IN Lately Gasoline prices have increased very noticeably, and now going to see friends is quite expensive. That is why most motorists began to seriously think about converting their car to gas. This topic has become of concern to many, and we decided to help you with this. In this article we will look at installing LPG from both the positive and negative sides, so it will be much easier for you to make a choice.

• Let's start with the most important advantage; many people have heard about it. When running on propane, the engine emits almost 3 times less carbon dioxide into the air.
• The service life before the first engine repair is increased by 2 times when compared with an engine that was operated exclusively on 95 gasoline.
• Propane and methane during combustion leave virtually no carbon deposits in the cylinders, thanks to which the engine operates simply excellent for a long time.
• The power reserve is 40-50% greater compared to gasoline and diesel engines. According to reviews, this is, on average, 1000 kilometers.
• The engine oil almost always remains clean due to the fact that the fuel burns almost clean.

Gas injectors under the hood of a car

Disadvantages of HBO:

• The cost of such an upgrade is quite high, usually the price is in the range of 20-30 thousand rubles. But you should not rely on these numbers, since the price also depends on the region in which you live, so the final cost of the work should be clarified at the nearest car service center.
• Starting the engine in winter is very problematic, so experts strongly recommend having about 10 liters of gasoline in the gas tank. Because of this, motorists have to start on gasoline, and then switch to propane or methane.
• The big problem lies in the fact that the installed equipment needs to be brought into technical certificate, and this process is long and quite painful. The difficulty usually lies in the fact that to register with the PTS you need to have a gas technician certificate. Such a document will be given to you at the service center after installation of the equipment. Then you need to contact the nearest traffic police department, where your HBO will be added to the PTS. The service, unfortunately, is not free - you will have to part with 10,000 rubles. But if you are stopped by traffic police officers and you do not have a mark in your PTS, then you will have to pay a hefty fine of 3,000 rubles.
• The final disadvantage is that you will practically lose the trunk, since this space will now be occupied by steel gas cylinders. And this is perhaps the most important drawback for passenger vehicles.

A gas cylinder often takes up a lot of space in the trunk of a car.

Although LPG has a large number of disadvantages, its installation is superior to diesel and gasoline ones in terms of maintenance and fuel economy. Let’s say the price of a liter of 92 gasoline is approximately 42 rubles, then gas of the same volume will cost you about 20 rubles. Yes, plus everything, as mentioned earlier, on gas the power reserve almost doubles. Therefore, from the point of view of saving and reducing car costs, the choice definitely falls on gas.

The cost of traveling in such a car will cost you two to three times less. For this reason, you will be able to recoup all the costs of installing equipment in six months or a year.

Installation, of course, can be done with your own hands, but then it will be extremely difficult to get a gas technician’s certificate. In fact, there are also craftsmen who do the installation on their own.

If you decide to do this, then you must be aware that during the installation process you may make a mistake, which in the future may negatively affect the operation of your car, up to its critical breakdown. Therefore, we strongly recommend that you trust the work only to professionals who have proven themselves well.

We have already discussed in detail the advantages and disadvantages of installing gas equipment. Next, we will consider the features of the fuel used in LPG. Motorists note significant savings in money; most people justify their choice only by this.

Gases, namely propane and butane, have excellent anti-knock resistance. The octane number is higher than that of gasoline and is equal to 105, so detonation of parts will definitely not occur. The gas does not have catalyst substances, so there is no destruction of metals, for example, as in gasoline or diesel fuel. The service life of an engine that runs on propane or butane increases by 60 percent.

Gas engine lasts longer

The rate of combustion of air with gas is slightly slower than with gasoline, for this reason the load on the piston part is reduced. Many European car manufacturers have noticed these features, and now some companies (Opel, Volvo, Fiat) produce hybrid cars.

Also, a distinctive feature of the gas is its good ability to diffuse with air. The gas mixes well with air and fills the engine with perfectly mixed fuel. Soot does not form on the walls of the combustion chamber, which is typical for gasoline. As manufacturers assure, gas-powered cars do not require engine repairs for approximately 10 years. Flooding of the spark plugs never occurs; all of the above makes the machine very reliable in operation.

If you think that in the event of an accident the cylinder is explosive, then you are greatly mistaken. Modern gas cylinders are equipped with an innovative valve. In the event of an emergency depressurization of the gas line, the valve is activated and no leakage occurs from the cylinder. The thickness of the walls of the cylinder is comparable to the thick walls of an armored safe.

In order for an explosion to occur, he needs to be thrown from a 50-meter bridge, and at the same time be hit by a high-speed locomotive. And in all other cases of damage, it is invulnerable, this is confirmed by multiple tests of the manufacturers.

Vehicle gas equipment

Therefore, know that all myths about explosion hazards remain just that, myths, and LPG is no more dangerous than a gasoline system.

Motorists who are planning to install gas equipment are mostly interested in how much they can save on fuel. And, of course, they are interested in whether the dynamic characteristics are significantly deteriorating.

Dynamics during acceleration is lost by about 6-7 percent - this is not that much, so it’s not so scary. If you look at fuel costs, the savings average 30%. In order to know the exact savings rate, it is necessary to take measurements and compare the results. The inaccuracy of the data lies in the fact that the equipment is produced in different modifications, and consumption depends on this.

Car gas equipment under the hood

Also, consumption depends on the correctness of adjustment of gas equipment; for this we advise you to contact competent specialists in this field. Now there are electronic systems control, they make it possible to further save up to 20% of gas.

There are two types of fuel for gas equipment - propane and methane. Their main difference for the motorist is only in the refueling method.

Methane is filled into the tank under a pressure of 250 atm, so the weight of the cylinder can even exceed 1 quintal. And for stable operation, for example, a Gazelle, you need at least 1 pair of cylinders. For this reason, the total load capacity may drop from 1.5 tons to 1.2-1.3, and this is clearly noticeable on small-tonnage Gazelles. Therefore, manufacturers do not recommend using LPG on lightweight cars, as this increases fuel consumption and vehicle acceleration.

External filling device with installed adapter for gas filling

Propane cylinders are more often used by motorists; this choice is deliberate, because they do not load the car so much. This gas is 1.5 - 2 times lighter than methane gas. It is also not operated under such high pressure, so the risk of explosion in an accident is much less.

More recently, they began to produce new gas tanks, they are called “toroidal”. Their advantage is that they do not require much space. Toroidal cylinders can be easily connected to each other, so you will have a large supply of fuel. The only thing is that the price for such tanks still remains quite high - from about 6,000 rubles for a 50-liter cylinder.

Toroidal cylinder in the trunk of a car

In order not to cause harm to the machine, you must follow several rules when operating:

• At a temperature environment below -15 degrees (for injection engines) and -10 (for carburetor engines), we strongly recommend starting on gasoline. In just 5 minutes the reducer will reach sufficient temperature, after which you can switch to gas.
• The transition from gasoline to gas should be made at 2 thousand revolutions, otherwise the engine will simply stall. HBO modification 4 has an interesting feature - there is a special button with which automatic switching occurs. Typically, the gearbox lasts 7 full years; after this time, we recommend replacing the membrane or the entire gearbox.
• When you drive into your garage in winter, immediately set the fuel switch to gasoline. Then you will not have difficulties starting the engine in severe frosts.
• At least 2 times a month it is necessary to drain the accumulated condensate from the gearbox. For this purpose, there is a special nut, unscrew it and wait about 5 minutes, and then screw it back. Depending on the modification of the gas equipment, the position of the bolt may change, but you can easily find it.

HBO switch button

Now you know what the positive and negative aspects of HBO are. Knowing all this, you can definitely decide whether you need to install this equipment. If you decide to install such equipment, try to contact reliable car services. This is the only way to be sure that no errors were made during installation. We wish you success!

Is it worth installing LPG on a car: pros and cons, savings, loss of power

Gas equipment for a car (GBO) is additional system in a vehicle, which makes it possible to supply the power plant not only with liquid bulk fuel, as provided by the manufacturer, but also to operate using gas. One of the motivations for installing gas equipment is the positive economic effect. Taking into account the fact that prices for gasoline and diesel fuel are rapidly increasing, drivers often decide to use gas in their cars.

By installing gas equipment on a car, you can reduce fuel consumption by up to 20%, if only high-quality equipment was chosen. In the auto market, we can find gas equipment from a wide variety of manufacturers, but the price does not always correspond to the quality of the product. Various types of liquefied gas act as gas fuel, such as: natural gas (methane) and oil (butane-propane mixture).

Depending on what type of fuel is used in the car and what type of engine the car has, cars are converted to use gas cylinder transport. It is divided into the following groups:

• single fuel;
• dual-fuel with independent supply of one of the fuels to the machine unit;
• dual-fuel gas-diesel engines, i.e., two types of fuel (gas and diesel) are injected simultaneously.

Each of these refueling technologies has its own specifics, but does not exclude common features. When analyzing gas equipment systems step by step, a factor such as “generation” is identified. There are five generations of HBO. 4th generation gas equipment is one of the most economical. It is also easy to operate and has good compatibility with Russian gas. While there is a fourth generation, the fifth is not entirely suitable for our country in some respects. The difference lies in the injection system: the “four” distributes gas into separate cylinders, the V generation sends gas in liquid form directly to the car’s engine.

All information on this system was installed for carburetor and injection cars, with a fuel injection system. The basis of its operation is the vacuum control of the fuel intake, a mechanical dispenser.

Advantages of the first generation:

• affordable price;
• admissibility of use on types of transport with an injection power unit;
• low price of fuel.

Disadvantage of the first generation: in high frosts it requires switching to parallel gasoline fuel.

II generation of gas equipment

The operating principle is based on the operation of an electronic atomizer that interacts with an oxygen sensor.

Advantages of the II generation:

• simple structure in the mechanism of the system;
• less fuel consumption compared to the first generation;
• low price of fuel.

Disadvantages of the second generation:

• increased need for gas consumption, compared to gasoline;
• in high frosts requires switching to parallel gasoline fuel;
• no possibility mechanical switching between gasoline and gas.

III generation of gas equipment

Advantages of the III generation:

• even less fuel is required when compared with the second generation;
• low cost of fuel.

Disadvantages of the III generation:

• quite high cost of equipment;
• in high frosts requires switching to parallel gasoline fuel;
• there is no possibility of mechanical switching between gasoline and gas;
• increased need for gas consumption compared to gasoline.

IV generation of gas equipment

This generation of gas equipment carries out its work by methodically injecting fuel using electric magnetic gas nozzles. Gas nozzles are located on the manifold, close to intake valve, like the third generation.

Advantages of the IV generation:

• lower fuel consumption when compared with the third generation;
• it is possible to automatically switch between gasoline and gas;
• low cost of fuel.

Disadvantages of the IV generation:

• high cost of the kit;
• in case of significant frosts, a mandatory transition to liquid bulk fuel is required;
• compatibility with car engines that use fuel injection directly into the cylinder is excluded;
• increased need for gas consumption compared to gasoline.

Due to electric magnetic gas atomizers, this system provides parallel and methodical release of gas injection. The operation of gas electromagnetic sprayers is determined using a gas control unit.

V generation of gas equipment

Gas enters each engine cylinder in a liquid state, which is the main difference between the fifth generation and the other four varieties. The kit for a conventional engine includes a gas pump that transfers liquid gas through the fuel system into the gas nozzle ramp, thereby creating the required regular pressure in front of the nozzles.

Advantages of the V generation:

• the ability to start the engine on gas fuel during high frosts;
• the ability to automatically switch between gasoline and gas;
• low cost of fuel.

Disadvantages of the V generation:

• high cost of equipment;
• practically beyond repair;
• high demands on gas quality.

To install HBO, you do not need to make any changes to the mechanism of your vehicle. Gas equipment for a car is an additional alternative to fuel, which you can always refuse and return to a mono-fuel type of engine.

The main change in the design with LPG is an electric magnetic valve, which is built into the fuel line, to be able to turn off the gasoline supply. By increasing the overall stroke of the machine, the valve independently selects the supply of fuel to the engine of the machine, which is its advantage.

Positive aspects of HBO:

1. High efficiency.
2. Emissions of pollutants into the atmosphere are significantly reduced, since it is environmentally friendly.
3. Engine performance improves. The engine runs quieter and has a longer service life.
4. The vehicle's power reserve increases. The transfer from one type of fuel to another occurs automatically, thus increasing the distance without refueling.
5. Possibility of using gas and gasoline.
6. Ease of use.

Negative points of gas equipment:

1. Fuel consumption increases by about 20%, but you need to take into account that gasoline is more expensive than gas.
2. Expensive cost of installation work. The one-time fee is quite large and cannot be divided into several payments.
3. Regular technical inspection is mandatory. This minus can be considered insignificant, since the driver controls his own car for his own safety.
4. The weight of the vehicle increases.
5. The spare wheel has to be carried in the trunk of the car.

Is it necessary to install HBO?

The system justifies itself in several cases. For example, if you have frequent trips, then a car that will be parked in the garage will not pay for itself so quickly. If you do not expect to purchase a new car in the near future, then the system is also needed. If the car's warranty period has come to an end, the system will be of use. And finally, the system justifies itself in cases where the engine consumption is about 10 liters of gasoline per 100 kilometers, only after switching to a gas power system.

How to install gas equipment on a car yourself

Installing gas on a car yourself requires some experience and knowledge of disassembling and repairing a car. Before installing gas on a car, you need to weigh all the risks and carefully study the process of installing gas equipment.

Let's look at the main tasks of the procedure and try to identify all the difficult points that arise during the equipment assembly process:

1. Choice required kit installations. There are offers from many manufacturers on the sales market, but it is better to pay attention to well-known brands; with them, fewer questions arise during the installation process and subsequent operation.
2. We determine the installation location of the pressure transducer (reducer). If there is a need for holes for installing a pressure transducer, they must be treated with Movil. It must be secured in an accessible place for further ease of maintenance.
3. If the kit contains electronic equipment, it is necessary to determine its installation location. The electronic control unit contains special microcircuits, as well as built-in programs, thanks to which you can organize the operation of all gas equipment. Any damage to the electronic control unit affects the operation of the electrical supply, transmission and exhaust system.
4. Correctly secure the gas nozzles. Their task is to timely supply dispersed gas to the cylinder block.
5. Create holes in the ramp for the bushing (in cars with carburetor engine drilling is carried out in the carburetor body). Before drilling the ramp, it is better to remove it in order to avoid chips getting inside. The holes should be closer to the fuel nozzles.
6. Correctly distribute the wires from the electronic control unit to the sensors, gas nozzles and the button in the car interior. The work will be considered high quality if there are no electrical wires hanging down. All trolleys must be connected with brass terminals and insulated with corrugation. It is important to maintain the correct polarity.
7. Installation of the cylinder, shut-off valves and filling structure. As a rule, they are installed in the place where the spare tire is located, under the back of the rear seat and under the bottom of the trunk. The location for the refueling unit may be in the gas tank flap or in the rear fender of the car. The choice is at the request of the car owner.
8. Laying a gas pipeline. To install gas equipment, both copper and thermoplastic lines are used. The latter are more resistant to corrosion. The gas pipeline is carried out along the bottom, where the brake and fuel system pipeline is located.

Gas equipment for the machine at this stage can be considered complete.

Setting up a gas installation

The first thing you need to do is fill the gas cylinder. Using a soapy solution, check all pipeline connections for leaks under pressure.

Manual adjustment is carried out only in the first generation of HBO. There is an electronic control unit, the system is regulated using software individually stitched onto the computer.

Maintenance of gas equipment on cars

What is included in the maintenance of gas equipment on a car:

1. Diagnosis of the equipment management system, as a result of which all its operating indices are identified.
2. Timely replacement of liquid and vapor phase filters.
3. Flushing gas nozzles - if the software identifies this need.
4. Examination of the system for impermeability.

Do not forget to indicate all the final results obtained regarding the fact of maintenance in the service book. This is an approximate maintenance procedure for generation IV gas equipment; for other, earlier generations, the process may vary.

How often do maintenance take place?

From the moment of installation of gas equipment, Maintenance must be carried out regularly after every 10 thousand kilometers. Once a year, before frost sets in, the entire gas system should be inspected. The maintenance book will give you a complete list of recommendations.

Certification and inspection of gas cylinders must be carried out once every 24 months. Those who have installed methane equipment must undergo certification and inspection once every 60 months. Checks take place at certain authorized locations. Inspection for confirmation is carried out by:

• visual inspection;
• hydraulic test;
• pneumatic test;
• test result.

The cylinder is considered defective if: there are breaks in the welded joints, chips on the surface of the gas cylinder. The cylinder is also unfit for use if damage has been clearly identified through physical impact. And finally, the cylinder is defective if traces of corrosion damage are detected, the thickness of which is 10% of the total depth of the cylinder wall.

Increasing the service life allows you to control the consumption of used fuel, as well as ensure the safety of yourself and your passengers from gas leakage. If a butane-propane mixture is used, a specific engine oil must be used. Then you will really feel everything positive sides use of a gas installation.

Most car owners dream of saving on the maintenance of their iron horse, without changing the nature of its operation. This is possible when installing gas equipment (LPG) on a car. What this gives, what are the advantages and disadvantages, and how to convert the fuel system with your own hands is outlined in the article.

What is LPG? LPG, or car gas equipment, is optional equipment, which makes it possible to store and supply gas fuel to the engine internal combustion(ICE). The type of car produced or converted depends on the type of gas fuel and engine. There are single-fuel, dual-fuel (the supply of one type of fuel is insignificant), dual-fuel (simultaneous supply of both types of fuel). The last ones are gas diesel engines.

Gaseous fuels are:

methane; propane-butane mixture.

The type of gas fuel used determines the classification of the LPG system. Systems are divided into generations, although this is not an official classification. There is simply no official one.

Did you know? In 1910 it was received liquefied gas, suitable for use in cars. The author of the development was the American V. Snelling.

History of appearance and distribution

Speaking about the history of gas equipment, perhaps we should first mention the appearance of the gas engine. It all started with the fact that in 1799, the Frenchman Philippe Lebon discovered illuminating gas (a mixture of H, CH4 and CO) and received a patent for its use. 60 years later, Etienne Lenoir developed and patented an engine that ran on such gas. Later, in 1883, the British were able to combine a gas generator unit and an engine in one unit. From that time on, the era of a new type of car began, which became very popular in the post-war years. But such a vehicle was not very effective. In the 30s of the 20th century, England and Germany, as countries poorly supplied with oil and having a sufficient number of cars, began to think about finding alternative type fuel.

The Germans accidentally discovered that when compressing the residual gases that arise after receiving diesel fuel, liquefied gas is formed. It condensed on the walls, it was collected and sold in cylinders. When the need for alternative fuel arose, they tried to use it in cars. In 1935, at the international automobile exhibition, five car models running on alternative fuels were presented (3 diesel engines converted to run on methane, liquefied petroleum gas, methanol, and two thermal ones). By 1942, the resulting shortage of traditional fuel made cars running on alternative fuels quite popular.

The massive conversion of vehicles to gas fuel began about 50 years ago. After the Germans and British, the baton was picked up by Poles, Turks, Chinese, Lithuanians, Italians, Russians, Ukrainians, Americans and many others. This active transition is explained by the fact that although a gas engine operates on the same cycle as a gasoline engine (Otto cycle), the alternative fuel gives a higher compression ratio - about 17, while gasoline engines usually have 10–12, in rare cases - 16 (gasoline AI-109).

Work principles

A machine equipped with gas equipment runs on a mixture of propane-butane or methane. They are pumped into cylinders under a pressure of 16 atmospheres (mixture) and 200 atmospheres (butane). They are located in trunks if the vehicle is a passenger car, or under the floor in the bus interior or on its roof. The cylinders are equipped with a multi-valve through which they are refueled and supply fuel to the system. In addition, the valve provides safe work the entire highway.

Did you know? Gas cylinders never fully refilled. In winter they contain 85% fuel, in summer - 75%.

Based on their operating principle, existing gas equipment systems can be divided into traditional and injection systems. The first option is usually used for carburetor cars. The air that enters the engine passes through a special mixer, capturing the required amount of gas. Here everything is directly proportional to the force of pressing the gas pedal (the harder, the more gas). In this system, gas enters the engine through injectors controlled by LPG electronics. The main principle of operation of the gas injection system is that it is invisible to the car’s factory electronics, that is, the control unit should not sense that the system is running on alternative fuel.

Is it worth installing HBO? Installing HBO on a car is a controversial issue. Some believe that this is pointless, others, on the contrary, are confident that it will pay for itself quickly and will save significant money on the purchase of fuel.

Advantages and disadvantages

The advantages of the equipment include:

efficiency; the engine runs more smoothly; the resource of the internal combustion engine increases due to a decrease in the load on its main components; the range increases (if the gas runs out, you can drive on gasoline); emissions of harmful substances are reduced.

Video: Gas for a car, pros and cons

Among the disadvantages are:

the cost of gas equipment is rather large, not everyone can allocate such an amount from the budget; gas cylinders will reduce the volume of the trunk or displace the spare tire; you need to constantly carry out maintenance, since gas can leak, which can lead to an explosion; due to the fact that methane is compressed under high pressure, if it explodes, there will be nothing left of the car.

Price and payback

Installing equipment on a vehicle for a propane-butane mixture will cost about 20,000 rubles, for methane - 50,000 rubles. Of course, you can find it cheaper, but it’s not a guarantee that it will be of high quality.

Important! Installation costs vary by region. Where gasoline is cheaper, the cost of gas is lower.

An analysis of the installation's payback will allow us to understand how reasonable such costs will be. For example, on ordinary cars recent years release, the average gasoline consumption in the city is 8 l/100 km. Let's assume that in a month the driver travels 1500 km, for which he spends 120 liters of fuel. Let's take the average cost of fuel at 35 rubles. /l. Then you will spend 4,200 rubles per month on refueling. A propane-butane mixture costs 16 rubles. /l. The monthly consumption will be about 130 liters, i.e. 2080 rubles. With such data, the savings amount to 2120 rubles. per month. But you need to take into account that there was a contribution to the equipment - 20 thousand rubles. It will pay for itself in a year, taking into account maintenance costs as well. It turns out that the savings seem to be quite good, but only if you drive over 1000 km per month. This means that installing HBO is beneficial for those who have a car - a way to earn money.

Cost-effective and environmentally friendly

Many people believe that if you install an LPG system, there will immediately be a noticeable loss of power in the car. In fact, the speed of propagation of the combustion front for gasoline is 0.85 m/s, for methane - 0.8 m/s, and for propane - 0.81 m/s. As you can see, the difference is not significant, some hundredths, so it is impossible to feel it, especially for modern generations of cars. The calorific value of gasoline is also not very different from this characteristic for gas.

Losses amount to 5–7%, so if car owners install gas equipment, then the loss in power will be practically unnoticeable to them, but the savings will be significant, since although gas consumption is a couple of liters more than gasoline, its cost is lower. Autogas also has a high octane number, which is why its anti-knock resistance is higher, it absorbs heat better due to cooling and parallel evaporation after injection. This all makes the motor more efficient.

Liquefied gas does not contain chemical components that can interact with motor oil which protects the engine from rapid wear. Accordingly, an engine running on alternative fuel will last longer and you will have lower maintenance costs. Of course, no one has canceled regular technical checks, because if the gas supply is interrupted, burnout and intense oxidation of the engine oil can begin.

Blue fuel wins over gasoline and diesel in terms of environmental friendliness. When it is burned, practically nothing is released into the atmosphere, and those hydrocarbons that remain are less toxic to the environment. All this is due to the fact that additives and aromatic substances are not used in the production of liquefied gas.

Which HBO is better?

To understand which gas equipment is better, you must first study its existing varieties.

Punishment for installing special signals in the Russian Federation Possible fines for deprivation of rights

The first generation is the very first gas systems for carburetor cars. They had a gearbox, a mixer and a simple fuel switch. A simple system effectively ensured the operation of a motor of this type. Despite the fact that carburetor vehicles have not been produced for a long time, the first generation system continues to be used. The second generation was a previous system adapted for injection machines. When installed, its task was to turn an injection gasoline car into a gas carburetor when alternative fuel is supplied to the engine. After some time, an electronic fuel dispenser was added to the system. Its role was played by a stepper electric motor, which corrects the state of the gas mixture (enriched or lean), relying on the readings of the oxygen sensor in the car. Such a system was not distinguished by the accuracy of fuel dosing, and the operation of the engine was accompanied by the sound of a pop. This forced equipment manufacturers to modify their creations. The third generation already had a rather complex design, the brain part of which was a computer that controlled the supply of fuel. The new gas equipment could also collect data from various vehicle sensors, analyze them and, based on the data received, form a gas mixture (open/close the injectors at the right moment and for a certain period of time). This system had an important advantage - it could be installed on those car models for which the later released HBO-4 (Audi 80 and 100) was not suitable. There was also a significant drawback - the system could not always process signals from all the vehicle’s sensors. Such a limitation and a considerable price were the reason that this generation could not become popular. The fourth generation is a universal system suitable for most gasoline modern cars. After analyzing the errors, the manufacturers decided that the fuel supply should be regulated by a car gasoline controller. The control unit collects data from sensors and regulates the fuel supply (opening of gasoline injectors). When the car switches to an alternative fuel, the gas system computer turns off the gasoline supply, interrupting the signal going to the gasoline injectors. The intercepted output signal of the gasoline controller going to the injectors is converted taking into account the properties of the gas (temperature, pressure) and sent to the injectors, but now gas ones. Thus, the result was a universal system with good fuel supply accuracy. Over time, gas systems were able to exchange data with gasoline ones, which increased the accuracy of fuel supply. Fifth generation - designed for vehicles with direct gasoline injection. They differ from conventional ones in the location of the injectors (directly in the combustion chamber, and not in intake manifold), so the gas system must constantly supply some gasoline to keep the injectors cool. In the new generation, the gas part of the system is taken from its predecessor, but needs calibration. Each car needs its own system firmware, so if the LPG manufacturer does not provide it, then it is normal to install the system on secondary market is not possible (there will be no calibration to ensure safe operation of the equipment). The sixth generation is a liquid gas injection system. They do not have a reducer, so the liquefied gas directly enters the nozzles, gasoline or gas. If this part is absent, there is no need to connect the cooling system. It would seem that it does last generation the most reliable and simplest. Unfortunately, the system reacts sensitively to the quality of the gas, i.e. this will mean that if there are many impurities in the fuel, it will quickly clog and fail.

The question of which gas-cylinder equipment is better, of course, is purely individual, since it depends on your car, but if we consider the existing options, then only the 4th and 5th generations are worthy of attention.

They are modern, equipped with good protection and are suitable for current vehicles. If we consider the 4th generation, then the systems of all manufacturers are identical in their ideology, only the mechanisms that put everything into action and some service functions differ. The fifth generation, of course, is inferior in efficiency to its predecessor, but since vehicle manufacturers are constantly modernizing them, the popularity of such a system is increasing.

Cars with liquid gas injection could be supplied to Russia by Holland, but after filling with Russian gas the systems quickly failed, so it is too early to consider the 6th generation. HBOs also differ in their manufacturers. The leaders are Polish and Italian systems, as they combine good quality and affordable price. Polish equipment is inferior in functionality.

Gas consumption

If a car is switched to gas, then drivers assume that its consumption will be greater. Indeed, since the calorific value of blue fuel is lower than that of gasoline or diesel, this will mean that its consumption is greater, but only slightly, due to the minuscule difference in performance. Of course, this will also be influenced by the generation of equipment. For HBO-2, where the feed is mechanically controlled, the difference can be a maximum of 20%. Optimized HBO-4 reduces the difference in consumption to 12–15%, and new Italian systems guarantee a reduction of up to 8–10%. In this situation, you can save about 2000 rubles. /100 km. The 5th generation equipment reduced the difference in fuel consumption to 5%.

DIY installation process on a car

The quality of installation determines how efficiently and safely the entire system will operate. If you are confident that you can install everything yourself, then here are some tips for you.

Installation of cylinder, VSU and gas lines

It is most convenient to install cylinders that have a toroidal shape. They fit in place of the spare wheel and do not take away any volume from the trunk. It is necessary to make a drainage hole in the bottom through which gas will evaporate in case of leakage and condensate will drain. You also need two holes for the gas supply and filling tubes. Some cylinders come with vent cups included, through which you can pass the tubes. Then you need a large hole for the glass and two small ones on the sides for attaching it. After installing the cylinder, a remote filling device (RFU) is installed. The hole for it is best made in the gas tank hatch. Before drilling a hole and installing the VZU, it is necessary to remove the wheel and wheel arch liner so that it is convenient to screw it on from the inside. Usually, the VSU kit includes the device itself with a sealing rubber band, an adapter for it, a lid with a rope, a nut with a cap and self-tapping screws. It is better to replace the latter with bolts so that they can be fixed more securely and can be unscrewed if necessary.

Then the backbone system is installed. It uses a thermoplastic tube with a fitting (8 mm) at the end. The filling line should come out of the cylinder under the bottom of the trunk and extend to the tank. The tube must be secured under the bottom so that it does not dangle. If possible, use as few screws as possible. Where possible, it is better to secure with ties. The required length of the tube is measured and fittings are attached to its ends. First, put on the nut, then the nut, and insert the fitting itself into the tube. It is fixed on it with a nut. You need to tighten it well to crush the bronze cap that seals the system. The wheel and fender liner are returned to their place, and then the fuel supply line is pulled. It runs under the bottom near the standard brake pipes. It also has fittings (6 mm) at the ends. Now the line is extended from the cylinder to the reducer.

The cylinder may have a multivalve equipped with an additional electric valve. It is connected using terminals. When the ignition is turned off, this valve shuts off the gas supply to the reducer and from the cylinder to the outlet. This allows you to avoid gas leaks during parking or an emergency.

Important! After drilling the holes, the ends of the metal must be coated with anticorrosive.

Engine compartment work

Stages of under-hood work when installing gas equipment:

choosing a location for the control unit; choosing a location for the gearbox; connecting the system to the gearbox; connecting the gearbox to the antifreeze line; drilling for injectors in the intake manifold; choosing a location for installing injectors; choosing a location for the fine filter; laying out the wiring in the corrugation and connection; installation gas-gasoline switch buttons.

The control unit must be firmly fixed to static parts of the body so that it does not come into contact with other elements of the engine compartment and does not interfere with their maintenance. The gearbox should be installed according to the same principle. To mount it you need a metal bracket. You need to think about the wiring from the control unit in advance. The gearbox is connected to the cooling system at the point where the antifreeze hoses exit to the stove. You need to cut them and connect the hoses from the gearbox with the antifreeze hoses going to the stove through the tees.

Holes need to be drilled and threaded in the exhaust manifold. Before screwing fittings into them, the threads must be coated with high-temperature sealant. The injectors should be located as close as possible to the manifold fittings. They need to be installed at an angle of 45° in the direction of movement of the fuel mixture and fixed firmly, preferably on a bracket. The hoses connecting the fittings to the nozzles should not be longer than 30 cm.

There is also a hole in the intake manifold for the vacuum reducer. It should also be threaded. The vacuum hose stretching from the manifold to the gearbox is designed to control the membrane in the gearbox. When the gas pedal is pressed in the exhaust manifold, a vacuum is created, pulling back the membrane in the gearbox. This provides more gas to the engine.

The filter with a sump should not interfere with the maintenance of parts in the engine compartment. It must be firmly fixed to the bracket. It is advisable that it have a temperature and gas pressure sensor. Route the gas line from the reducer to the injectors through the filter. Pack the wiring from the control unit into a corrugated box and lay it along the standard factory lines. Mark a place for the fuel switch button and pull the wire from the control unit to it through the hole between the engine compartment and the passenger compartment. Drill a hole and install the switch.

Important! All manipulations are completed by setting up the HBO system using special software, as well as checking it for leaks and, if necessary, adding antifreeze to the cooling system.

Security measures

Safety in equipment installation is paramount. Any vehicle fuel system is a fire hazard, especially a gas one, so the cylinder must have a multi-valve with an additional electric valve, which will guarantee that in any unforeseen situation, and even when stopping the car, the gas supply will be automatically shut off if the ignition is turned off.

When installing a gas system yourself, you should avoid using cylinders that have already been used. Their service life is limited to 12 years, since then corrosion processes begin in them, thinning the walls of the vessel. Accordingly, the risk of depressurization increases. This can be dangerous because the balloon will suddenly burst when the pressure in it increases.

In general, modern gas systems make them reliable and protected from fuel leaks, so if you are hesitating whether to install gas equipment in your car due to the unsafety of the system, then you can rest assured. The main thing: install HBO according to all the rules.

In light of the constant rise in price of processed “black” gold products, many car owners have turned their attention to the use of a propane-butane mixture of gases, instead of traditional gasoline or diesel fuel. There are many rumors that cars with gas equipment often explode, valves burn out from using a propane-butane mixture of gases, engine power decreases, etc. Is this so and what actually happens, what are the pros and cons of HBO at the moment, we will try to figure it out within the framework of this article.

Advantages of HBO

The advantages of HBO include:

Disadvantages of HBO

But not everything is so smooth, there is also the other side of the coin. As part of the article, the pros and cons of LPG, it is also necessary to consider the disadvantages of installing LPG.

Let's move on to consider the disadvantages of a car with installed LPG:

• “eats up” useful trunk space. (or takes the place of a spare wheel). You can combat this by using a “dokatka” or a repair tube with a special composition for repairing tire punctures on the road;
• Installation of equipment for gas treatment, like the equipment itself, is the most expensive financial part. But the more gasoline or diesel fuel your car consumed before installing LPG and the greater the annual mileage, the faster the payback for the installed LPG will come;
• The cost of car maintenance increases (instead of just one fuel system it will be necessary to carry out maintenance of two systems simultaneously.);
• Engine power decreases (but when correct settings and adjustments it is almost not felt) ;
• Even with LPG installed and configured, the car needs to be refueled with gasoline or diesel fuel, of course in much smaller volumes (in gasoline engine the recommended transition from gasoline to gas occurs when the engine temperature reaches 40 degrees; To operate on gas, a diesel engine still needs an “ignition” portion of diesel fuel, since the gas itself does not ignite due to compression. The consumption of traditional engine fuel increases significantly with decreasing ambient temperature);
• The consumption of a propane-butane mixture will be higher than that of gasoline or diesel. Depending on the generation of installed gas equipment, the average gas consumption can be 20 - 30 percent higher than the consumption of the “native” fuel for the engine;
• It is more difficult to ignite the gas-air mixture, therefore more stringent requirements are imposed on the ignition system than when operating on gasoline;
• When the engine is running on gas, the valves and valve seats experience an increased temperature load (since there is no effect of evaporation of fuel droplets from the seat and its cooling), which leads to the need to be more attentive to adjusting and checking valve clearances or the condition of hydraulic compensators;
• Propane-butane is heavier than air, so when operating a car in a garage with a pit, it is necessary to produce all the gas outside, and drive into the garage on gasoline, in order to avoid gas accumulation and a possible explosion. This may also serve as a refusal of some parking lots to accept gas-powered vehicles;
• When planning a route, you need to pay more attention to the presence of gas filling stations on it for possible refueling;
• Nowadays, when converting a car to LPG, in 85 percent of cases it is necessary to make changes to the registration documents of the car (replace the technical passport).
