How to increase engine power without adding new parts. Increasing the power of the naturally aspirated engine By which the engine power can be increased

Probably every car enthusiast sooner or later wonders how to increase the power and torque of his own "iron horse".

For some, this question arises after numerous modifications of the car: it seems to be hung with all kinds of body kits and looks like a sports car, but “from a traffic light”, God forbid, at least somehow worthy to get under way.

For some, increased power and torque is a matter of paramount importance, on which attention is focused even when choosing a car. However, there is no limit to desires, and the possibilities of an already familiar car are clearly not enough.

The main and most in a simple way an increase in power and other speed characteristics of a car is, paradoxically, replacing the car with another one that is more consistent with the needs of the car enthusiast.

Despite the obvious simplicity of solving the issue of increasing the speed characteristics of a car in this way, it does not suit everyone.

Someone will have an ensuing question about the availability of the necessary amount of money, someone has become a familiar car “painfully” to change it, and someone just wants to enjoy the process of step-by-step “pumping” of their car.

In any case, if you want to "speed up" your car without completely replacing it, then this article is written for you.

How to increase engine power using an injector control unit?

Now this is the most popular option for increasing the power parameters of a car, assuming that the installed block for changing the nozzle control pulses gains control over the fuel system through the nozzle “needles”.

Such a power increase is mounted diesel engine break the wires that control the fuel injector.

Due to its operation, the signal is delayed, the injection angle changes, and fuel is saved, since the impulse is so short-lived (no more than 0.0002 seconds) that it is blocked (it is simply not perceived by the unit).

Since the pulse changing units do not have their own high-voltage stages that can send a signal, they are not able to broadcast non-basic pulses.

Similar blocks manufactured under brands known to Russian motorists GreenBOX, TUNIT, R-Box, TuningBox, BlueBOX, TBS, Power-Box, can be mounted on all types of diesel engines equipped with an electronic injection complex.

Their use saves fuel. In addition, the cost of the products is more than affordable.

At the same time, the described block for increasing the power of a diesel engine also has a number of disadvantages:

Decrease in the resource of the internal combustion engine, caused by the fact that the device excludes some functions of the fuel supply;

Complex and time-consuming installation;

Increased emission of harmful compounds;

The diesel particulate filter wears out very quickly due to the lack of impulse, which is designed to ensure the correct combustion of fuel.

Increasing engine power on high pressure diesel engines

Improving the operation of the engine is achieved by installing a special unit that replaces the modes of operation of the fuel pump (fuel pump). Suitable for some engines equipped with old pumps (manufactured before 2008) under the brand name BOSCHVP 44.

Such installations are characterized by the fact that in them high pressure is accumulated in the pump, and not in the HP rail.

The increase in diesel engine power is achieved by lowering the values ​​shown on the fuel pressure indicator. And this becomes the reason for an increase in pressure in the pump (in its body).

All the work is performed by a solenoid valve (it is he who controls the pressure). Moreover, it acts outside the nominal modes, which leads to a decrease in the resource of the high-pressure pump.

The described increase in the power of the diesel engine has the following advantages:

Fast installation;

There is no direct impact on the amount of emission of harmful elements;

The resource of the cylinder block is not reduced;

The element base is inexpensive and objectively uncomplicated.

This block, of course, is also not without its drawbacks:

Smoke is recorded from the exhaust pipe (it is called after operational);

The resources of the electromagnetic injector and the high pressure fuel pump are reduced;

The floating engine speed is noted.

How to increase engine power in other ways?

Expensive and complex methods involve internal intervention in the device of a car engine (technical tuning) and require significant time expenditures for execution and a lot of experience of a specialist who performs tuning, as well as very significant financial investments from the customer.

Expensive and sophisticated ways to increase power and torque

Expensive and complex methods involve internal intervention in the device of a car engine (technical tuning) and require significant time expenditures for execution and a lot of experience of a specialist who performs tuning, as well as very significant financial investments from the customer.

At the same time, the difference in the operation of the car engine after the implementation of expensive technical tuning will be very noticeable, but it will also noticeably affect its motor resource.

In the future, repairing a forced engine will be very expensive, if you manage to find performers at all. Costly ways to increase engine power and torque include:

Installation of supercharging on a naturally aspirated engine

This is the most expensive and difficult way of technical tuning of a car, which includes a number of complex measures (selection of a supercharger, forcing the engine, reworking collectors, testing, etc., etc.).

In doing so, the supercharging unit can enormously increase both power and torque by significantly increasing the air entering the combustion chamber. There are two types of supercharging: the most common turbocharging (eng. "Turbocharger") and mechanical supercharging (compressor, eng. "Supercharger").

Replacing the engine

Definitely, in order to increase the power and torque in this way, a great experience of the performer is required and significant financial costs both for a new motor and for its installation, which implies a number of measures: determining a suitable engine for replacement, revising the engine compartment, connecting electrics, replacing an ECU etc.

Forcing

It implies mechanical intervention in the engine device: replacement of certain elements of it (for example, a camshaft, throttle or turbines) for sports, as well as the boring of the cylinder block, which will lead to an increase in engine displacement and, accordingly, to an increase in power and torque.

In addition, the engine will become much more demanding in terms of maintenance.

Budgetary and affordable ways to increase power and torque

There are also less expensive and affordable methods that do not imply technical intervention in the engine device.

The basic principle of such methods is the elimination of restrictions in the operation of the engine, provided by the manufacturer in order to comply with the car's environmental standards, as well as in order to reduce the number of warranty calls to service centers.

The available ways to increase power include:

Chip tuning

Software optimization of the engine operation implies a change in the factory-set operating parameters of the ECU by various methods: using electronic modules or using manual adjustment ("firmware") of the control unit program.

Electronic modules have a large number of advantages over the ECU "firmware" service, and negative reviews in their direction, as a rule, are not supported by any facts.

At the same time, the latest electronic modules ProRacing OBD are able to automatically, autonomously and safely increase the speed characteristics of cars.

Chip tuning is the most effective budgetary way to increase power and torque and does not require any technical intervention. In addition, smart chip tuning helps to reduce fuel consumption.

Modification or replacement of the air intake system

This is achieved by installing a zero resistance filter or by completely replacing the standard intake system.

In the first case, the increase in power will be within 2-5% due to a decrease in the resistance of the filtering element to the incoming air flow, in the second case, the increase can be very significant not only due to a decrease in the resistance of the filter, but also due to an increase in the supply of cold air.

This method deserves a detailed study and requires the correct approach to implementation, otherwise you can seriously harm the engine or simply not feel the result.

Modification or replacement of the exhaust system

For the sake of ecology, as well as to significantly reduce the outgoing noise, the standard exhaust system to some extent limits the capabilities of the engine.

Certain measures, such as replacing the catalyst with a flame arrester and removing the particulate filter, will make it easier for the engine to breathe out and provide a certain amount of additional Horse power and newton meters. A more expensive, but also more effective way is to completely replace the standard exhaust system with a sports one.

This will not only give a noticeable increase in power and torque, but also level the life of the exhaust system with the life of the car as a whole. sports exhaust systems are made of high quality stainless steel.

Use of quality consumables

Iridium Spark Plugs

This method cannot be called tuning, but that does not mean that it should be neglected. The use of high-quality and expensive consumables, such as engine oil, filters, spark plugs, as well as fuel, directly affect both power and torque.

A separate point is the use of expensive iridium or platinum spark plugs, which have a very significant effect on the operation of gasoline engines and can not only increase power and torque, but also reduce fuel consumption.

All mainstream car manufacturers make compromises. They are pushed into this framework by motorists, although they themselves do not suspect it. This situation can be easily explained: they are forced to produce competitive, cheap, reliable and economical cars that they will buy over and over again.

Why increase engine power?

Each car owner has his own motive for increasing the engine power output, starting with the banal desire to stand out from the crowd with a more aggressive engine sound and dynamic acceleration, ending with an increase in engine thrust and improvement of its practical qualities. There are several ways to increase the engine power of a production car:

• chip tuning;


• an increase in the working volume;


• an increase in the compression ratio of the fuel;


• weight loss;


• replacement of cylinder heads and camshafts;


• modernization of the intake system.


• modernization of the exhaust system;

A brief overview of methods for increasing the power of the internal combustion engine

In addition to the fact that chip tuning is one of the most effective, it is also one of the simplest from the point of view of direct technical method of intervention in the engine. The essence of the method comes down to installing a new program in the engine control unit.

With the displacement, everything is simple: the more fuel the engine is able to burn in one crankshaft revolution, the more power it generates. The working volume of the internal combustion engine is increased by boring the cylinders.

By increasing the compression ratio to a certain level, you can potentially develop more power with constant fuel consumption. That's why all high-performance race cars run on high-octane gasoline - their engines compress the fuel mixture to the maximum and get the utmost efficiency.

By replacing the heavy pistons of the engine with lighter ones, it is possible to reduce the waste of energy for changing the direction of movement of the pistons and for stopping them. The lighter the piston, the less energy is wasted.

Many factory engines have one intake valve and one exhaust valve per cylinder. By installing a cylinder head with an increased number of valves on the cylinders, you can significantly increase the flow of air into the combustion chambers and increase power.

The more air is forced into the cylinder, the more power it will give out in one revolution of the crankshaft. For this, the engines are equipped with special turbines and compressors that pump air into the cylinders under pressure.

If the exhaust gases do not escape well from the combustion chambers and the exhaust system as a whole, they steal engine power. The smaller the section of the exhaust pipes, the stronger the back pressure and the lower the power of the internal combustion engine.

Fans of motorsport in all its varieties know that there is an entire industry dedicated to increasing the efficiency of engines (and therefore increasing their power). But such work belongs to the category of very expensive, and the power units themselves are truly unique products in terms of complexity. Therefore, their installation on conventional mass-produced cars is, in principle, impossible.
What should ordinary motorists do who are dissatisfied with the performance characteristics of their four-wheeled friends? In the modern world, speed is everything, and in conditions of congestion of urban transport highways, any delay at an intersection is fraught with large temporary losses. An increase in engine power allows you to feel more confident on high-speed highways, where overtaking time is a critical indicator, especially when it comes to budget cars, initially characterized by the presence of a low-power motor.

There are many ways to increase the power of a power unit. Some of them are quite simple, others are complex and costly. Some give an almost imperceptible increase in power, others can please with a noticeable improvement in dynamics (and a deterioration in other characteristics). Therefore, it is advisable to study all popular techniques describing how to increase engine power. Informed means armed, and knowing the advantages and disadvantages of each of the demanded methods will allow you to choose only those that will meet your expectations and capabilities.

Increase in working volume

It is this indicator that owners of small cars are embarrassed to give when they are asked about the characteristics of the car. Well, increasing the volume of the combustion chamber is perhaps the most radical way to make your car more responsive and dynamic.

It is known that the concept of "engine displacement" includes several interrelated characteristics: how much the piston moves, what are the number and diameter of the cylinders. But since structurally changing the number of cylinders is impossible even theoretically, there remains an effect on the other two above-mentioned parameters.

An increase in the diameter of the cylinders is in principle possible, but since they move in chambers designed specifically for factory dimensions, boring will be required for the corresponding size of the cylinder block. If the BC is made of cast iron, new larger pistons must undergo additional processing, which consists in applying microroughnesses to the piston walls, which serve to retain the oil film. Needless to say, such work is almost impossible to perform in garage conditions.

If the cylinder block is made of aluminum and equipped with wet liners, the task is much easier. In this case, boring is not required - it is enough to change the sleeves for products of the required diameter, purchasing them at any auto shop.

The second way to achieve the desired results is to change the piston stroke upwards. Structurally, this can be done by using a crankshaft with a different geometry (the radius of the crank increased by a certain amount). The choice of a suitable crankshaft will also not cause problems - there are a considerable number of products on sale intended for installation on different types and modifications of power units, including forced ones.

Of course, the increase in engine power when using such a radical method will be quite noticeable. But do not forget that this characteristic of the car is closely related to other parameters (in particular, with the torque and the value of the crankshaft revolutions). In fact, an increase in piston stroke means that the greatest amount of torque is developed at the minimum value of the crankshaft revolutions.

If we talk about specific numbers, then an increase in the piston stroke / cylinder diameter provides an increase in power by about 10%, while the engine operation in all modes will become noticeably smoother.

Among the disadvantages of the method, it is worth noting the following:

• increased fuel consumption (by about the same percentage);
• the high cost of the procedure itself;
• in some cases, it becomes necessary to change the design of the clutch; for the correct operation of the ECU, an appropriate flashing will also be required;
• in such cases, the use of low-quality oil and fuel is highly undesirable;
• the resource of the motor will decrease due to a decrease in the thickness of the cylinder walls.

Increasing the compression ratio

This method is considered one of the most effective. The orientation towards a change in the upward direction of the compression of the air-fuel mixture in the combustion chamber is good because the increase in power in this case is not accompanied by an increase in fuel consumption. Agree, this is extremely important for budget cars (to be more precise, for car owners with limited funds).

Surely you will have a logical question: for what reason do automakers not maximize the compression ratio at the factory? Do they leave some reserve for self-tuning? The fact is that the characteristics of the gasoline used do not allow an arbitrary increase in the compression ratio. This indicator is calculated in such a way as to minimize various knocking phenomena. Increasing the compression ratio is a good way to increase the engine power by an impressive amount, but it does this by using a fuel with a higher octane number. And it, of course, is more expensive.

So the benefits of such tuning become less obvious. One thing pleases: the power unit after such a modernization will demonstrate greater efficiency even at the previous power, which is achieved by reducing fuel consumption. In general, increasing the compression ratio really turns out to be the most profitable way to increase engine throttle response.

Currently, two different techniques are used to increase the compression ratio:

• the first way is to install a thinner GB gasket. Its main disadvantage is the increased likelihood of valve-piston contact. So before using it, you need to carefully calculate everything. A variation of this method is the installation of other pistons in the power unit, which have appropriate recesses to prevent collision with the valves. In this case, of course, the valve timing will undergo changes, and appropriate engine settings will be required, but this, as they say, is a one-time procedure;
• the second method consists in cylinder boring - we have already talked about it above. We just did not mention that, in addition to increasing the volume of the combustion chamber, such a procedure increases the compression ratio, since the volume of the combustion chamber remains unchanged, only the volume of the cylinders itself changes. Before increasing engine power in this way, it is necessary to understand that with standard engine settings, the lower the compression ratio, the higher the power increase.

Intake system tuning

Most of the methods related to improving the intake path are aimed at reducing the resistance of the air flow directed into the combustion chamber. Technically, such improvements cannot be called very difficult, but they require the use of a large number of dissimilar parts and materials, allowing you to achieve a significant increase in power. Consider how to increase the power of a carburetor and injection engine by changing the elements of the intake system.

Installing a zero resistance filter

This term refers to a modified air filter, the main purpose of which is to increase the throughput of the filter element. In a standard VF, it is made of a sufficiently dense material that provides reliable filtration of the air entering from the outside. The "zero" uses a more rarefied material. Due to the deterioration of the filtering capacity and changes in the design of the filter itself, the air passes through the filter with less losses. It should be noted that the increase in power in this case will be scanty, so this method should be used only in conjunction with other similar measures.

This method is also quite popular, but, as in the case of using the Federal Tax Service, one should not expect tangible results. If you use it as part of a comprehensive tuning of the power unit, then a slight increase in the performance of the intake system will ultimately give a quite tangible cumulative effect.

Installing the receiver

The main purpose of this part is to smooth out air pulsations on the way to the combustion chamber. This is achieved through the use of shortened inlet pipes and an increase in the volume of the receiver chamber. This method belongs to the easy one, showing good results. Its feature is the maximum filling of the cylinders with the air-fuel mixture in the high speed range with adequate reduction at low speed. With a corresponding change in the design of the receiver, the opposite result can be achieved, when the torque increases in the low speed range, but in the rest of the range, the engine throttle response decreases.

A modification of this method is the installation of an intake system with a modified geometry of the air passages, which makes it possible to achieve a better filling of the cylinders in the entire torque range, guided by information about the remote control and the current crankshaft rotation speed. The option is very effective in terms of power gain, but also quite expensive to implement.

Removing the intake manifold

In some cases, instead of the intake manifold, "pipes" are installed - shortened pipes, tuned mainly to the high speed range. This is a very effective but expensive solution, which involves the installation of a separate DZ for each cylinder. At the same time, the volume of air supplied to the combustion chamber increases sharply, due to which a more stable engine operation at XX, low / medium speeds and very productive work in the upper range is achieved. The reaction time to pressing the accelerator pedal is noticeably reduced.

Pay for all these delights will have to increase fuel consumption and reduce the resource of the power unit.

As you know, the main task of the exhaust system is to ensure the removal of combustion products of the fuel-air mixture, as well as to reduce the sound effects and vibration resulting from the explosive ignition of the mixture. V modern cars the exhaust system is also equipped with elements that reduce the toxicity of the exhaust. Unfortunately, the law of conservation of energy also applies to cars. Therefore, with the obvious benefit of the muffler, the principle of its operation is to slightly reduce the engine power.

There are several ways to reduce power losses by upgrading the exhaust system:

• installation of direct-flow elements;
• use of downpipes;
• increase in the diameter of the outlet pipelines;
• bifurcation of the exhaust system.

To understand how you can increase the engine power due to the exhaust system, let's consider what the power of the power unit generally depends on.

The main and determining parameter is the quantity / quality of the air-fuel mixture. Moving from TDC to the lowest point, the cylinders are filled with a mixture of air and fuel, and the parameters of this mixture depend on the degree of pressure coordination between the inlet and outlet tracts.

In other words, an increase in the volume of air supplied to the compressor station increases the engine power, but exactly the same increase in performance must be achieved from the exhaust tract, otherwise there will be no increase in power.

The converse is also true - an increase in exhaust capacity in itself contributes to an increase in engine power. Let's consider the main ways to achieve the set goals.

Collector

The main share of the losses in the exhaust system falls on the manifold. Replacing it can reduce these losses. In professional tuning and motorsport, a "spider" is used for these purposes - a collector that differs from the standard one both in shape and quantity, as well as in the order of arrangement of the intake pipes.

In particular, for four-cylinder power units, either “4/2/1” type manifolds (long version, four pipes are first combined into two, and then merged), or a short “4/1” scheme are used. The latter option allows you to get an increase in power in a relatively small range of revolutions (6000 and above), so it is used mainly on sports cars. The first scheme is considered ideal for amateur tuning of the exhaust system, since it gives a significant increase in torque in almost all ranges.

Resonator

Increasing the resonator diameter is another way to increase power in co-current exhaust systems. The principle of operation of this tuning is to improve the process of blowing the cylinders during the exhaust phase, which makes it possible to increase the torque of the power unit. This procedure, referred to as “tune exhaust,” is used to modify the timing schedule. The actual tuning of the resonator assumes its greatest effect in the region of decrease after the maximum, which makes it possible to increase the CM at high speeds. To achieve an increase in power at low speeds, the resonator is tuned to work in the growth section to the maximum.

If a catalytic converter is installed on the machine, it is dismantled with the installation of a direct-flow flame arrester. Such modernization allows the resonator to withstand maximum temperature effects without any special consequences, but from an environmental point of view, there is nothing to do with such exhaust in Europe. Russian regulations allow for such a modification.

Silencer end

One of the main tasks of the exhaust system is to reduce the noise level emitted. For this purpose, the end part of the muffler is installed as far as possible from the manifold, thereby reducing its resonance effect. The use of a straight-through muffler instead of a conventional muffler allows the resistance to gas flow to be reduced to zero, at least at the last stage of the exhaust. To compensate for the drop in sound-absorbing properties, a pipe of a smaller diameter with perforations is placed in such a muffler. The space between the outer / inner pipes is filled with a fibrous material with good heat-resistant properties (eg glass fiber). To prevent the filler particles from "flying into the pipe" in the literal sense of the word, a barrier in the form of a fine mesh is installed between the fiberglass and the pipe.

Exhaust noise in such a muffler is effectively absorbed by the filler, penetrating through the perforations. However, over time, the padding layer still becomes thinner, which begins to affect the sound emitted by the direct-flow muffler. And the effect of the increase in power as a result turns out to be insignificant.

Chip tuning

This term means making changes to the on-board computer software aimed at changing the operation of the actuators that affect the operation of the power unit. In the general case, it is not necessary to perform chip tuning solely in order to achieve a noticeable increase in power, but it should be recognized that most cases fall on just such an upgrade of the ECU firmware.

Initial factory settings are not always optimal. In particular, automakers are trying to correlate the ignition timing, controlled by the on-board computer, with a certain region, but it turns out that in most cases it turns out to be slightly overestimated. For this reason, the combustion process of fuel assemblies is not so efficient.

The second reason why the ECU is tuned for an increased ignition timing is to reduce the load on the transmission units. The other side of this solution is an increase in the reaction time of the engine to the driver's actions, as well as a decrease in the stability of its operation. Some factory settings of the on-board computer lead to increased fuel consumption.

Chip tuning is able to eliminate all of the above disadvantages:

• increase many parameters of the power unit;
• to increase the comfort for the driver;
• raise the torque to an acceptable level;
• reduce fuel consumption.

From the point of view of cost, such a modernization of the car is considered one of the most inexpensive, while they do not interfere with the design of the car, which leaves a chance for the seller to fulfill the warranty obligations. Note that chip tuning for conventional cars does not allow you to achieve significant results, but you cannot do without it if you have made changes to the design of the power unit or a component adjacent to it, since this also changes the characteristics of the engine.

This type of car modernization demonstrates the greatest effect on sports cars, which already have powerful characteristics.

Reduced weight on flywheel and pistons

It would seem that weight reduction should not affect the power performance of the motor in any way, but in practice, the use of a lightweight flywheel allows you to achieve a small, but quite positive effect. The fact is that due to the reduction in mass, this part spins up much faster, allowing the engine to reach a high-speed mode in a shorter time. The average increase in power with this tuning method is about 4%, so it is suitable for a wave as a cumulative effect.

The advantage of this method is also that its implementation is within the power of. To increase the power of a diesel engine, it is enough to purchase a lightweight flywheel (its cost varies between 2000-5000 rubles), and its installation does not require a large number of operations. As a rule, such modernization is carried out in a complex manner, together with changing the compression level, chip tuning, installing a zero resistance filter and other simple and inexpensive modifications.

The second method related to reducing the mass of auto parts is the use of forged pistons. In theory, less energy should be spent on its movement, and in terms of strength characteristics, it will give odds to pistons made of traditional materials. However, one cannot count on a significant effect here either. Nevertheless, racers actively use it, since even a slight increase in power is very important for them. Recently, such an operation is increasingly included in the range of services provided by firms specializing in tuning.

Reduced frictional force

It is this force that has the maximum effect on reducing the efficiency of any device in which rubbing parts are used. In the engine internal combustion the greatest losses occur at the moment of movement of the piston in contact with the cylinder walls, which acts as a guide.

Of course, engine oil helps to reduce friction - this is its main purpose, but its physical characteristics can be improved using various additives.

You should be careful here - the composition of a particular additive can be optimized for completely different purposes. Ideally, you need to buy additives of complex action, which not only create an additional layer between rubbing surfaces, but are also capable of other deposits. Undoubtedly, the most important effect of such an additive is considered to be the formation of a new protective layer, which is characterized by a very strong bond with one of the rubbing surfaces and an excellent oil-retaining property.

And since engine power depends on the presence of losses in the CPG, reducing friction will have a positive effect on vehicle dynamics. According to various sources, this method of increasing the throttle response of the power unit gives an increase in power at the level of 6-7%, increasing the resource of the piston group and reducing fuel consumption.

However, many reviews do not contain any positive results from the use of such additives, so their use can be a simple waste of money.

In most cases, the use of camshafts with modified cam geometry is practiced to increase engine power, although there are directly opposite solutions.

It all depends on whether the size of the cams is increased or decreased. In the first case, a greater valve travel is provided, which has a positive effect on the dynamics of the power unit. However, there are some nuances here: there are modernized camshafts on sale designed to increase engine power at low, medium or high crankshaft speeds. It also depends on how much the valve lift is increased. If it is insignificant, we have an addition of power at low revs, if maximally (but in such a way as to exclude the collision of the valve with the piston), we will increase the engine thrust at high revs.

So if you want to increase the power of a naturally aspirated engine while minimally changing the design of the power unit, installing a sports camshaft will help you solve this problem. Of course, after replacing this part, a valve adjustment procedure will be required.

Turbocharging

This method is deservedly considered the most effective in terms of increasing the power of the power plant. This is evidenced by the growth in the number of models produced with such an option (turbocharged modifications are not uncommon today even for the AvtoVAZ concern).

However, even owners of turbocharged cars have something to strive for, since they also have many opportunities to increase the amount of horsepower produced by the engine. Such tuning is especially interesting for owners of low-power cars (for example, with an engine capacity of 1.4-1.5 liters). In order to achieve even more impressive results, it is enough to install a large turbine. An alternative option is to increase the pressure of the factory turbine. All of these methods allow you to achieve a noticeable increase in power, but requires a lot of changes. Instead, you can pick up a turbine with higher performance indicators, since there are a huge number of models on the market for most running models.

If we talk about installing a turbine on an atmospheric power unit, then this is already considered a cardinal change in the design of a car, affecting both engine settings and operational points (the need for mandatory warming up of the engine, even in the hot season, more frequent replacement of consumables).

However, the power gain can be almost twofold, so the work is worth the effort. It all depends on your skills, as well as the characteristics of the turbine being installed. True, in addition to the turbine itself, an intercooler will have to be installed, since it heats up very much during operation, and the engine heats up with it. To reduce the heat load, some increase the amount of coolant entering the radiator and improve its airflow by installing a more powerful fan. Old injectors also need to be replaced with more efficient ones, since they are not designed for such a heavy load.

The principle of operation of a turbocharger is quite simple - providing a much larger amount of air into the cylinder. And since the intensity of the combustion process depends to the maximum extent on the availability of oxygen (recall, there is not much oxygen in the atmospheric air - about 21%), the more air enters the combustion chamber, the better. By the way, the turbine is driven by the exhaust energy without using the engine power, however, it must be taken into account that there is a direct relationship between the accelerator pedal depression and the turbine performance.

The advantages of this method of increasing the power of the power unit are obvious: in terms of efficiency (a two-fold or more increase in engine efficiency), there is no alternative to it, the use of a turbine can be canceled with one click of a button if there is no need for it.

But this is also the most expensive method, which also requires flashing the on-board computer software. It is also unrealistic on its own - this requires appropriate experience and knowledge. Although powering the turbine does not require the power take-off of the engine, at high speeds an increased fuel consumption is inevitable - this is required by elementary physical laws. The installation of the turbine requires substantial revision of many other components of the machine - the use of more durable parts, strengthening the braking capabilities. Finally, get ready for the fact that the engine resource will be obviously less than the scheduled one.

Brief conclusions

As you can see, even a low-powered car can be made to work like a sports car. As a matter of fact, it makes sense to compare such tuning with doping used in professional sports. But there is no direct prohibition here. The maximum sanctions are loss of warranty, which is irrelevant after the end of the warranty period. Most of the current methods give a relatively small increase in power, therefore, if you do not use the most radical methods, it makes sense to use a combination of several less significant ones.

But in any case, you will have to pay something for the increase in the output of the motor. In most cases, this is an increase in fuel consumption.

Hello dear visitors and blog readers. In the article we will tell you how to increase the power of a car engine with your own hands, without resorting to the help of professionals. car motor is a fascinating process.

Allows you to find out the device of the power plant and improve performance. Often the owner is not satisfied with the power of the motor. The car enthusiast tries to "squeeze out" the maximum without outside help due to competent optimization and the use of special equipment.

We must remember that you should not engage in amateur performances. Individual parts or components of the motor can be damaged. Compliance with the technology for increasing engine power will provide a positive result.

Experiments can damage the engine. All the steps described in this article are recommendatory in nature. The driver accepts obligations related to possible malfunction of the engine due to erroneous actions. You need to be careful and careful in the process of increasing engine power with your own hands.

At the end of the article, you can find a video that allows you to better understand such a question as increasing engine power with your own hands.

Car engine power is the value obtained by multiplying the engine speed by the torque. The power value is constant for a particular car. To increase the power, you need to increase the revs. In fact, not everything is as simple as it might seem at first glance.

There is a mechanism for changing the valve timing. It plays the role of a regulator in the motor power supply system and is a stumbling block on the way to increasing the engine power.

The main task of the gas distribution mechanism in the engine is to ensure uniform filling of the cylinders with the fuel-air mixture. The gas distribution mechanism, depending on the ranges of engine operation, shows different results.

Low revs do not contribute to the complete filling of the engine cylinder chambers. The rise in power is slow and sluggish. For the full filling of the chambers, the engine speed should be close to 3000 thousand. Abuse of a sharp set of speed and an increase in revs at the start is fraught with rapid clutch wear.

Powerplant manufacturers have learned to overcome the limitations of the gas distribution mechanism. The electronic system automatically adjusts the phase change conditions depending on the driving style. Allows to ensure effective filling of the cylinder chambers with a fuel-air mixture without the threat of clutch breakage.

Most of the cars driving on the roads of the country cannot be classified as new. Almost 80% of the car park is represented by used cars with different mileage levels.

The prevailing motors are not equipped with a sophisticated electronic control system. Fuel-air mixture is used ineffectively. Machines can and should be upgraded to increase engine power.

Do-it-yourself car engine power increase

The increase in engine power is a kind of tuning. Outwardly invisible to the human eye, but noticeably improves the dynamics and quality of the car.

There are 6 ways to increase power:

1.Installation of a wide-phase camshaft instead of the standard mechanism.

Convenient and budget option for increasing power with your own hands. An intelligent minder is taken as assistants. Without the use of special equipment, you can cope.

Installation of an improved camshaft allows for maximum filling of the cylinder chambers at high rpm. Excellent cost-to-cost ratio.

2.Reduction of friction force.

A decrease in mechanical losses with a decrease in frictional force makes it possible to achieve positive dynamics of an increase in power. The emphasis is on reducing the force of friction between the pistons and the cylinder walls.

There are several ways:

• reducing the thickness of the piston rings;
• reduction of the piston skirt;
• modification of the connecting rod-to-piston attachment by displacing it into the piston bosses.

3. Reducing the weight of the piston group.

To increase the engine power, replace the standard engine elements with lightweight versions. The effectiveness of the method is questioned by experts. Today it has not been proven that changing the weight of the piston group increases the power of the engine.

4. Cylinder boring.

An effective but costly method. Increases engine power. Boring cylinders increases their volume. The result is a nice gain on standard power. Among the minuses, the increased "appetite" of the car is distinguished, expressed in an increase. The cost of using the machine goes up.

Many manufacturers of motors, when creating, lay in a power reserve. It is normally not used. Designed to keep it stable. The power is limited by electronic blocking.

Software, straight arms and a laptop are able to unlock the hidden reserves of the motor. You can achieve an increase in power. Among the disadvantages of the method of tuning the engine, there is a decrease in the service life.

Probably, every motorist at least once thought about how to increase the engine power, and whether it is possible at all. Yes, there really is such an opportunity, and not even one. The fact is that the engines of mass non-sports cars are focused on a certain balance of power, fuel consumption, reliability and durability, cost, and other indicators. This balance can be moved to one side or the other in various ways.

The octane number indicates the resistance of the fuel to detonation, i.e. to explosive combustion. Contrary to popular belief, gasoline in the cylinder does not explode, but burns out. And this combustion should be as uniform as possible, distributed throughout the entire volume of the cylinder. Only then will it deliver maximum power. Due to detonation, noticeable drawdowns occur in the engine power. Therefore, you can fill in gasoline with an octane level higher for more confident traction.

Advantages:

• this is the simplest and fastest method that does not require any preparation and work;
• in case of a bad experience, you can just as easily and quickly return everything back;
• the engine runs smoother and quieter for improved ride comfort.

Flaws:

• fuel with a higher octane number is significantly more expensive;
• the increase in power is very small, it is often difficult to feel it;
• without adjusting the ECU, it is possible to reduce the resource of engine parts.

Installing a sports air filter

For fuel combustion, oxygen obtained from the air is required. Therefore, at the intake stroke, the engine sucks in a portion of air from the outside into the cylinder. In this case, the air must pass through the filter for cleaning, because of which force must be applied to suck in the air. On sports cars, air filters of zero resistance are installed, through which air passes very easily. As a result, the engine practically does not waste its power on sucking in air.

Advantages:

• zero resistance air filters are quite cheap;
• they are very simple and short-lived to install and remove on their own;
• in case of contamination, there is no need to change them, you can simply clean them.

Flaws:

• this method gives a maximum of 3% power gain;
• the air is less cleaned, which is why the engine becomes clogged faster;
• truly sporty models can be expensive.

Modification or replacement of the exhaust system

As with air intake, pushing the exhaust gas requires some force because it travels through the tortuous path of the muffler and catalyst. But you can install the so-called forward flow - a simplified, less tortuous exhaust system, as well as remove the catalyst and install an enlarged exhaust pipe. Then the exhaust gases will pass as easily and quickly as possible.

Advantages:

• the method does not require particularly large labor and money costs;
• a good master can achieve a power increase of up to 7%;
• returning a conventional exhaust system is not difficult.

Flaws:

• such a system makes a lot of noise;
• the problem of passing the inspection due to increased air pollution;
• the appearance of vibrations.

Modification of the control program (chip tuning)

All modern injection engines are controlled by special firmware in the electronic control unit. The parameters of the standard firmware are focused on a certain fuel consumption, ride comfort, etc. The master, with the help of special equipment, can correct the gas distribution phases, timers of the operation of various subsystems so as to achieve an increase in power.

Advantages:

• all work takes place at the program level, without mechanical changes;
• increase in power from 10% to 30%, depending on the type of engine;
• dynamics is leveled, turbo lags are smoothed, responsiveness is increased;
• there are no problems with passing the inspection.

Flaws:

• chip tuning requires high qualifications of the master, otherwise it will only get worse;
• a reflash engine requires high octane fuel;
• the service life of certain parts of the engine, for example, pistons, may decrease.

Changes in cylinders and piston group

One of the old, "old-fashioned" methods is the so-called boring. Its essence lies in the machining of the cylinder block, after which their working volume increases. Since this also requires replacement of the piston group, usually the pistons and connecting rods are immediately changed to lightweight, sporty versions. The calculation is that the engine will spend less energy on the rotation of the crankshaft.

Advantages:

• you can achieve a tangible increase in power, at a level of up to 10%;
• increased engine endurance thanks to sports components;
• the engine runs smoother, and the sound can also change - become deeper.

Flaws:

• increased fuel consumption due to an increase in the working volume;
• the procedure is quite expensive in terms of money and labor intensive;
• the total engine resource may be reduced due to thin cylinder walls;
• high quality fuel and engine oil is required;
• clutch rework and ECU modifications may be required.

Installation of a nitrous oxide injection system

A way very much loved by professional street racers and those who try to be like them. The bottom line is to install cylinders with compressed gas N 2 O, from which it is injected into the intake manifold of the engine. Nitric oxide has a complex effect: it cools the injected mixture, increases the oxygen concentration, and also causes a more intense and uniform combustion of the fuel-air suspension.

Advantages:

• a very effective way - acceleration is several times more intense;
• the view of a set of cylinders and a special acceleration button is very effective;
• does not significantly affect engine life.

Flaws:

• short duration of action, depending on the volume of the cylinders;
• a good nitrous oxide kit is very expensive, and cheap ones are just dangerous;
• enhanced brake system and sharp steering.

Turbocharging the naturally aspirated engine

Combustion is nothing more than a combination of a substance with oxygen, and there is quite a bit of it in the air - less than a quarter of the total volume. To make the fuel burn more intensively, you need to pump as much air as possible into the cylinder. This is what a turbocharger or a turbocharger does. The turbine, which blows air into the intake system, is powered by the energy from the exhaust gases. Therefore, the performance of the turbine directly depends on the force of pressing the accelerator.

Advantages:

• the most effective way - the power can grow 2 times or more;
• the set of works usually also includes tuning the ECU firmware;
• the turbine can be turned off by pressing a button if it is not needed.

Flaws:

• a very expensive method that also requires high professionalism;
• fuel consumption increases significantly, especially at high speeds;
• in parallel, it is required to replace many engine parts with more durable ones;
• it is also recommended to significantly strengthen the braking system;
• overall engine life can be reduced due to increased wear.
