Power 100 horsepower diesel engines. The best diesel engine for a passenger car

Many people often wonder what more economical car with diesel, if diesel fuel costs almost the same as 95-grade gasoline? We answer: the difference, first of all, is in consumption. A diesel engine with a comparable volume consumes almost twice less fuel. That is, on one tank, a diesel car can travel almost twice as far as the same gasoline car. In addition, modern diesel cars They are almost no different from gasoline engines in terms of sound, and even superior in performance.

But there are also negative aspects: diesel cars are initially more expensive than their gasoline counterparts. And in addition, they have a reduced service mileage and, as a rule, higher maintenance costs. And high-quality diesel fuel cannot be found everywhere. So you need to choose an economical diesel modification with a calculator in your hands - in most cases, such a car pays for itself only with high mileage over a fairly long period of time.

Stated city consumption: 4.4 liters per 100 km
Price: from 792,900 rubles

Another representative of the PSA concern is equipped with the same 1.6 diesel engine as the 408 sedan. Stylish appearance, comfortable and high-quality interior, complemented by a good level of equipment, should justify the fairly high starting price. In addition, potential buyers have at their disposal a robotic transmission, although not the most modern. And the fuel consumption declared by the manufacturer seems very optimistic.

Engine: diesel 1.7 (110 and 100 hp)
Checkpoint:

The elegant five-door Korean hatchback is trying its best to look like a crossover, which it actually is not. However, the high profile of the body allows you to conveniently enter a fairly comfortable and well-equipped interior. The high-tech diesel engine has very decent characteristics at the level of the best European manufacturers. The only drawback is that the trunk is not the most spacious and convenient.

Engine: diesel 2.0 (110 hp)
Checkpoint: manual 5-speed
Acceleration to 100 km/h: 10.7 seconds
Stated city consumption: 6.4 liters per 100 km
Price: from 815,000 rubles

A recognized standard in its class in many respects. The car has already changed generations, but for now you can still buy the current model in car dealerships. The two-liter diesel engine does not have high power, but this does not prevent it from remaining quite dynamic and economical. Disadvantages include the lack of an automatic transmission and the high cost of additional options.

Engine: diesel 2.0 (140 hp)
Checkpoint:
Acceleration to 100 km/h: 9.5 seconds
Stated city consumption: 6.8 liters per 100 km
Price: from 847,000 rubles

With a diesel engine it sells worse than other modifications. The reason is the high price of the diesel version. But with this engine, the Focus truly reveals the talent of a well-tuned chassis. In general, a two-liter engine makes Ford Focus the most dynamic diesel car for the money. In addition, on the car side there is a choice of three body styles: hatchback, sedan and station wagon.

Engine: diesel 1.6 (128 hp)
Checkpoint: automatic 6-speed
Acceleration to 100 km/h: 11.7 seconds
Stated city consumption: 7.9 liters per 100 km
Price: from 899,000 rubles

Another new product on the domestic market. The Korean manufacturer decided to equip the i30 with an economical diesel engine exclusively in a practical station wagon, which is quite logical. The car is distinguished by a spacious interior with a large 530-liter trunk. However, the average level of equipment against the backdrop of a fairly high cost still scares off potential buyers.

Engine: diesel 1.6 (112 hp)
Checkpoint: robotic 6-speed
Acceleration to 100 km/h: 12.6 seconds
Stated city consumption: 5.2 liters per 100 km
Price: from 947,000 rubles

Positioned as a crossover car, it is actually a comfortable compact van. On the 3008 side there is a spacious interior, a very comfortable and roomy trunk, as well as an enlarged ground clearance. In addition, the handling, which is adventurous for a family car, even allows for a little mischief on the road. As a result, the suspension is quite stiff. And the same simple “robot” as on the C4 does not add comfort to the car.

Engine: diesel 2.0 (140 hp)
Checkpoint: robotic preselective 6-speed
Acceleration to 100 km/h: 8.3 seconds
Stated city consumption: 7.2 liters per 100 km
Price: from 999,000 rubles

The main advantage of this car is its spacious and well-thought-out interior. The station wagon body with a 580-liter trunk turns the Octavia almost into a passenger van. And the two-liter diesel engine gives the car very decent dynamics. The machine only offers preselective DSG box, which serves as an excellent match for a technologically advanced engine. The only pity is that you will have to pay a lot for all this pleasure.

Engine: diesel 2.0 (160 hp)
Checkpoint: manual and automatic 6-speed
Acceleration to 100 km/h: 9.6 seconds
Stated city consumption: 6.9 liters per 100 km

The German compact van is equipped with the same engine as the Golf. Only the larger model has two transmissions available. The main advantage of the car is that the buyer can choose between a five-seater version with a huge trunk, or take the latter’s place with two additional seats. In any case, the ergonomically adjusted interior will remain comfortable for all passengers.

One of the most popular cars of its class in Russia. Mondeo captivates, first of all, with its excellent balance of consumer qualities. Spacious salon with a large trunk, an optimal level of equipment, good driving characteristics without sacrificing comfort and three body styles to choose from, the car is a good offer in its segment. Many may note that the design is not the most modern, but with the advent of the new generation, this drawback will be eliminated.

Built according to German patterns, it lost a significant part of its French charm, but gained more pragmatism and functionality. It is interesting that the power line, even for Russia, is made with an emphasis on diesel engines, which the French are an expert in. The owner will especially be pleased with the top-end 2.2-liter engine with excellent performance.

Engine: diesel 2.0 (136 hp), 2.2 (204 hp), 3.0 (240 hp)

But the “co-platform” Peugeot 508 remained faithful not only to its non-trivial design, but also to the proprietary air suspension, with which the C5 is one of the most comfortable cars class. And it has the widest choice of diesel units, including a 3.0-liter engine with diesel traction. For pragmatic connoisseurs of comfort and dynamics, there is also a station wagon.

Engine: diesel 2.0 (184 hp)

The most affordable car with a diesel engine, belonging to the premium segment. A powerful engine and refined handling give the car a sporty character. True, a trained driver who can cope with the rear-wheel drive habits of a compact hatchback will be able to fully appreciate it. The BMW 120d is especially good with the optional sports package, which includes retuned suspension, steering and brakes.

Engine: diesel 2.0 (140 hp)
Checkpoint: robotic preselective 6-speed
Acceleration to 100 km/h: 10.2 seconds

Checkpoint: automatic 6-speed
Acceleration to 100 km/h: 10.4 seconds
Stated city consumption: 7.9 liters per 100 km
Price: from 1,334,000 rubles

One of the most unusual cars on the Russian market, attracting attention primarily with its unusual appearance. The number of design delights both in the exterior and in the interior is off the charts. However, this does not prevent the DS5 from being a convenient machine for everyday use. It’s just a pity that due to the design features of the stylish model, it didn’t get Citroen’s signature air suspension.

Engine: diesel 2.0 (143 hp) and 3.0 (245 hp)
Checkpoint: CVT and robotic preselective 7-speed
Acceleration to 100 km/h: 9.1 (5.9) seconds
Stated city expenditure: 5.7 (6.8) liters per 100 km
Price: from 1,430,000 rubles

Another representative of luxury cars, which can be purchased with an economical diesel engine for reasonable money. True, the smooth variator that comes with the 2.0-liter engine noticeably dampens the acceleration dynamics. And the equipment corresponding to the premium status will have to be purchased from the list of expensive options. But the range also includes a powerful 245-horsepower diesel engine, but the price of such an A4 is already approaching two million rubles.

Volkswagen Passat/ Passat CC

Engine: diesel 2.0 (170 hp)
checkpoint: robotic preselective 6-speed
Acceleration to 100 km/h: 8.6 seconds
Stated city consumption: 6.6 liters per 100 km
Price: from 1,454,000 rubles / 1,434,000 rubles

The coupe-shaped version of the regular Passat with a diesel engine under the hood surprisingly turned out to be slightly cheaper than its more traditional counterpart. The reason is a more modest configuration. The traditionally ergonomic interior is more comfortable in a regular Passat due to the larger headroom. For those who value style over practicality, the CC modification is addressed. But the speed characteristics and efficiency indicators of the two cars are almost identical.

Engine: diesel 2.0 (184 hp)
Checkpoint: automatic 8-speed
Acceleration to 100 km/h: 7.6 seconds
Stated city consumption: 5.4 liters per 100 km

The BMW 3-series, which recently changed its generation, has placed a bet on comfort and safety in its new generation. The car has not lost its proven habits on the road, but the sporting spirit of the Bavarian brand is no longer felt so clearly in this car. In any case, the diesel “Treshka” dynamic characteristics outperforms all competitors with a diesel engine of comparable power.

Despite the general low demand in Russia for cars with diesel engines, they are represented on the domestic market quite widely. Even a passenger car can be chosen to suit every taste and budget. And what is planned by the government may significantly encourage buyers to choose diesel modifications.

Back in 1991, only 15% were used passenger cars. Then they could not be a significant competitor to gasoline ones and had practically no advantages. But by 2015, they had won more than half of the market and became the most popular, because new diesel models have become more powerful, more economical, and more reliable.

Now the share of diesel engines has fallen somewhat, and a scandal with Volkswagen due to inaccurate information regarding emissions of harmful substances played a significant role in this. However, they are still in demand and occupy 45% of the market. They are used where gasoline engines cannot provide the required power with acceptable fuel consumption, for example, in SUVs.

Advantages and disadvantages of diesel engines

The best diesel engines for passenger cars have significant advantages over their gasoline counterparts:

1. Economical - they consume much less fuel. Savings can reach 40%, which makes maintaining a car more profitable even now, when the cost diesel fuel slightly more than the cost of gasoline.
2. Durability – not so long ago such motors had a short lifespan. Modern models can easily cover 500-600 thousand kilometers.
3. Simple design. Unlike gasoline engines, there is no complex ignition system and some other components that often cause problems.

Of course, there are also disadvantages:

1. Sensitivity to fuel quality. Even the best diesel engine can be easily damaged by bad fuel - you will have to change the injectors.
2. Periodically required Maintenance, more often than for gasoline ones. Because of this, the maintenance of such a car increases somewhat.
3. The sound during operation is not as quiet and pleasant as that of a gasoline one. On the other hand, some people like the growl of a powerful engine.
4. Warming up in winter takes longer.
5. Environmental friendliness is generally comparable, but Lately The standards have become more stringent, and not all motor manufacturers can withstand them. Therefore, the number of diesel cars has decreased.

These disadvantages are quite relative and solvable - gasoline engines have their own unpleasant moments. Therefore, diesel engines continue to gain popularity throughout the world. Nowadays, many models have been released that are superior to their gasoline counterparts in many respects. Let's look at the best of them.

Top best diesel engines

The engines are all different and if you compare all their characteristics, it is unlikely that you will be able to identify the best contender. Some have better parameters, while others have others. In addition, they have different designs and different volumes. Therefore, we will choose the best representatives of diesel engines that have proven themselves to be the best.

Volkswagen 1.6 TDI

The TDI diesel engine, developed by engineers, remains unrivaled Volkswagen company. It is the most economical. With a volume of 1.6 liters, the designers managed to significantly reduce the engine’s appetite, while maintaining power, 90-120 hp. With. in different modifications.

The 1.6 TDI engine uses an injection system Common Rail, Bosh injectors and variable geometry turbocharger. Thanks to the increased pressure in the fuel supply system, it was possible to achieve fuel consumption of only 4.5 l/100 km. And this is while driving slowly around the city. On the highway, this engine shows a much better result - 3.5 l/100 km according to the passport, but in reality it can be close to 3 liters.

The 1.6 TDI diesel was used in many cars of the Volkswagen, Audi, Scoda brands. Its estimated resource is 350,000 kilometers.

BMW M57

This engine is included in the ranking of the 10 best diesel engines as the most powerful. One of the modifications of this 6-cylinder engine developed a power of 380 hp. With. and a torque of 800 Nm. This, of course, will please fans of powerful BMW models, but such an engine is not used in ordinary production cars - they are weaker, by 150 horses. Although most competitors don’t even have that. Range Rover SUVs and the BMW 330D used options up to 286 hp. With.

This motor is created using proprietary modular technology. It serves for a very long time and up to 600 thousand kilometers, but its repair requires considerable investment. However, it is also one of the most reliable in the world in terms of service life; many old cars with this engine have been running on the roads for a couple of decades.

Hyundai/Kia D4FB (1.6 CRDi)

The Korean development is distinguished by its simplicity of design, so it is unpretentious and reliable engine, but is demanding on fuel quality. However, it uses all modern technologies - fuel system Bosh common rail, variable geometry turbo, Swirl Control Valve? And much more.

This engine is ahead of most competitors in terms of reliability, while it has low fuel consumption and starts easily in cold weather. It is also quieter than other diesel engines.

Fiat 2.0 JTD

Fiat diesel engines have earned recognition all over the world, and the JTD line, which appeared in the mid-90s of the last century, turned out to be so successful that it was used in many European cars, and then in some American ones. An Italian company that produces mediocre cars has developed one of the best diesel engines in the world.

With regular maintenance, OEB series engines last a very long time without losing power. It is used in cars Alfa Romeo different models, Suzuki SX4, Chevrolet Malibu, and many others.

Toyota 1ND-TV

Toyota developed its diesel engine independently. The result is one of the best diesel engines for small passenger cars. It has a power of 55 hp. With. for every liter of volume and easily covers 500 thousand kilometers. Dynamically, it behaves excellently, and its environmental characteristics are very good even modern requirements, although it was developed back in 2002.

Based on this diesel engine installed on popular models Honda Civic and Accord, a newer 2.2 i-DTEC was developed, which turned out to be no less successful.

Volvo D5

This company did not have its own diesel engine for a long time and used the developments of other companies. In 2001, a motor of its own production was created. It turned out to be very successful and durable - it easily covers 700 thousand kilometers without loss of performance, of course, with proper care.

This motor was used for Volvo cars C80, Volvo B70 and some others.

conclusions

Recently, due to stricter environmental requirements, the share of diesel engines on the market has been decreasing. But best models show excellent performance, and engineers continue to work to improve the design. And although gasoline engines are more common, there is still a need for diesel engines, especially where efficiency and power are required. This means that they will not leave the stage completely soon.

Nowadays, many car enthusiasts prefer diesel engines. Consulting agency J.D. PowerAsiaPacific conducted the study. According to its results, a quarter of all new cars are produced with diesel engines. And that's not all, there is a tendency for this figure to increase.

Back in the 2000s, only one in 10 cars had a diesel engine. And in the future, based on the opinion of experts, this figure will grow annually by 1–2%. There are many reasons for this: the ever-increasing price of fuel and stricter control of environmental standards. Another plus is the possibility of refueling with biodiesel, which is increasingly relevant in light of declining oil reserves.

Pros and cons of a diesel engine

Let's highlight why a diesel engine is better than its gasoline comrades:

• Economical. Fuel requirement is 30–40% less.
• Life time. It is durable, on average it will last you twice as long as its gasoline counterpart.
• Fuel prices. Diesel fuel is much cheaper than gasoline throughout the country.
• Simplicity. It does not have an ignition system, which eliminates many problems. Reliability is higher.
• Environmental friendliness. Emissions carbon dioxide very small.

If you have mentioned the advantages, then you need to talk about the disadvantages.

• Reliability. Low-quality fuel will quickly destroy the injectors.
• Maintenance. It will cost you about 20% more.
• Comfort. The sound of the engine when starting is very unpleasant, and warming up will take longer.
• Convenience. If you use a manual transmission, you will have to change gears more often.

Most Russians, when they hear the word diesel, remember the smell of diesel fuel on the bus, as well as jeans and watches from the brand of the same name. In Europe, this word is associated with the name of the German inventor. And it is a symbol of a reliable, inexpensive car.

In our country it is not so popular, probably due to the climate. And in last years Almost nothing has been heard about the “million-dollar” engines for which the 90s were so famous. Most likely, this is due to the fact that it has simply become unprofitable for large corporations to produce reliable, long-lived engines.

Rating of the best diesel engines

Having studied the ratings of major car dealerships around the world, we can come to the conclusion that the best diesel engines for passenger cars are no longer smaller copies of truck units, but a full-fledged product. Just look at the durable 1.9 TDI engine from the well-known Volkswagen concern.

At the present time, according to experts, it is considered the most balanced in both power and dynamics.

It comes in various modifications, does not conflict with local fuel, and in good hands runs about 500 thousand kilometers. Of course, a lot depends on proper maintenance and operating conditions, but still this model deserves attention.

Let's not ignore the brand new cars of the Passat series. They are now equipped with BlueMotion engines. The engineers did a great job, they managed to reduce fuel consumption despite the fact that the power did not change and varies from 90 to 120 (hp).

Now he spends only 3.3 liters. per 100 km. They achieved this by updating the turbine and increasing the pressure in the combustion chambers. They also began to pollute the environment much less, which is important in the current conditions.

We also cannot ignore Mercedes and Nissan engines - these are the most reliable engines; Subaru engines will be placed a little lower in our rating. But not only the Japanese and Germans have good diesel engines; for example, the Americans have a good engine from Ford. We'll put Opel on the next level. We’ll stop here, because there are too many complaints about Renault engines, and VAZ engines deserve a separate conversation about them.

What can cause engine failure?

Like everything in our world, the reliability of a diesel engine is a relative concept. It is worth noting that turbine diesel engines are not as reliable as atmospheric ones, because the turbine tends to break down often. There are many factors influencing the work besides assembly. Same engine internal combustion will behave differently under different conditions.

As mentioned above, diesel engines are very dependent on the quality of the fuel. Diesel fuel of dubious quality can seriously damage your engine after the first refueling. The point is that outdated Soviet engines can easily handle such fuel, while new ones are guaranteed to fail. Especially if somehow there is some water in the fuel.

This is due to the formation of sulfuric acid, which negatively affects all parts of the car. It occurs as a result of the reaction of sulfur with water, the catalyst of which is high temperature in internal combustion engines.

Although even without the absence of water, excessive sulfur content significantly reduces the service life of the oil. Due to the ingress of crankcase gases into it. Sulfur will also quickly ruin your particulate filter. It should be remembered that if you have doubts about fuel, then to be sure that the car is working, you will have to change the oil twice as often.

If you follow simple rules, even the least successful motor will serve you faithfully for a long time. You need to use only high-quality motor oil, if possible of the same brand, replace it on time, and, of course, do not overheat your unit - do not allow the engine to operate under increased loads.

"Eternal" engines

Let's return to the legendary million-dollar engines already mentioned above. There is an opinion that there used to be engines that could drive up to 1 million kilometers, and this was on those roads, without major repairs. One of these was the Mercedes-Benz M102 model. He came to replace the M115. The M102 has become lighter, but at the same time more powerful.

He achieved this by using thinner walls, which made it possible to lower the crankshaft lower. The cylindrical heads were made in a cross-shape, on which there are suspended V-shaped valves, the drive operates through the central rocker arm of the camshaft.

The engine itself began to be produced in the 80s of the last century in two assemblies. Both configurations were installed in the W123 family of cars.

After 4 years, a new family appeared - W124 and the engine was improved. Hydromounts replaced rubber ones. An oil pressure sensor, a serpentine belt, a crankshaft and lightweight connecting rods were installed on it, and the oil filter was also replaced.

The carburetor version was the last in the history of the brand.

It is also worth mentioning the 2.5 liter diesel engine from Toyota. This engine was considered very good and could run back its million. But of course, with a major overhaul, because the cylinders wear out much faster. The lifespan of the cylinders is approximately 300-400 thousand km.

Let's remember about VAZ engines. Although the build quality of these cars leaves much to be desired, the engines on the frets are very good, I would like to highlight the 8-valve internal combustion engines. For a VAZ-2112, a mileage of 200–300 thousand kilometers is considered quite normal, after which it will have to undergo major repairs.

And VAZ-21083, with the right approach and timely oil changes, can last even longer - up to 400 thousand km. But the 16-valve engine breaks down very quickly. To summarize, the entire VAZ product is a lottery. Marriage is very common.

It’s difficult to say something unambiguously about Renault engines - in the line of power units there are good models, and there are downright weak ones. The most reliable diesel engine is considered to be the 8-valve K7J engine, 1.4 liter, and K7M, 1.6 liter. They are made simply and successfully, and therefore break very rarely.

They have a timing belt (gas distribution mechanism) drive, the valve is adjusted with screws. K7M - used in RenaultSymbol/ Sandero/Logan/ Clio cars. The above-mentioned VAZ uses the Lada Largus in its car. By all accounts, the K7J looks good, except for the power - it is not enough for a mid-size passenger car mobile

On average, the most economical engine can run up to 400 thousand km without major repairs.

As for the Renault company, its engines are not characterized by high reliability - these are 1.5 liter, 1.9 liter and 2.2 liter diesel engines. Problems often arise with them. Under load, the crankshaft begins to knock, and when the same begins to happen to connecting rod bearings- this is definitely a major overhaul. This diesel engine from Renault will not be able to run much, and major repairs will have to be done after 130–150 thousand kilometers.

The largest and smallest engines

Also wondering, which diesel engine is the best? To date, the Wartsila-Sulzer RTA96 is the most powerful diesel engine. Its size is comparable to a three-story house.

This two-stroke engine weighs 2300 tons. Has two modifications - 6 and 14 cylinders and 108920 Horse power. This engine is designed for large merchant ships. The latest engine option will burn 6,280 liters of fuel per hour.

And the smallest diesel engine can fit on one finger. In the near future, microscopic engines that will be fueled by hydrocarbon fuel and driven by a tiny generator are on the way in Europe and the United States.

Conclusion

From what is written above, we can see that there are plenty of problems. It is quite possible to understand a motorist who does not want to take risks to save money. But with proper operation, the motor will work for a very long time.

There are cases when such engines lasted 1–1.2 million km even on low-quality fuel.

That is, if you need a car designed to last a long time, then you should think carefully about the diesel option. Also, don’t forget about efficiency. Every 100 kilometers will give you about 30% savings in fuel, which justifies the higher cost of passenger cars.

Diesel engines are initially considered the most reliable. When choosing a car with a similar power unit, you need to focus on its optimal technical specifications.

When choosing the best diesel engine for Russia, you can count on the successful realization of its potential. Experts note that older generations of diesel engines are distinguished by their simple design and safety margin.

Review of top units

Which engine models have gone down in history and proven themselves to be the best? First of all, the answer relates to German products, which have a well-known quality and can satisfy all quality standards.

Mercedes-Benz OM602

The OM602 diesel engine is considered one of the best. Main characteristics:

• 5 cylinders;
• 2 valves per cylinder;
• Mechanical fuel injection pump.

The three principles listed above allow the unit to maintain a leading position in terms of mileage and resistance to operational tests. Diesel engines were produced in 1985-2002, which indicates their reliability.

The main advantages were reliability and efficiency. At the same time, the power was comparable to the average - 90-130 horsepower.

The previous generation was OM617. The successors, namely OM612, OM647, have also earned a high level of popularity.

Motors are actively installed on the following cars:

• Mercedes in the body of W124, W201, W210;
• G-class SUVs;
• vans T1, Sprinter.

Advice! The list of the best diesel SUV engines includes the Mercedes-Benz OM602, as well as its two successors - OM612, OM647.

BMW M57

Bavarian BMW engines managed to gain a high level of popularity and an ideal reputation. All 6-cylinder units were reliable and had decent power ratings. The cars could accelerate from 201 to 286 horsepower.

The engines were produced between 199 and 2008, and they were successfully installed on the majority of Bavarian cars. All famous BMW models were pleased with the presence of the M57 diesel engine. In addition, they can be found on Range Rover.

The ancestor also turned out to be a real legend - M51. Its release was carried out in 1991-2000. As you can understand, the Bavarian manufacturer BMW has accumulated very good experience, which is now being actively used in the development of diesel engines.

Experts note reliability, because serious breakdowns are rare. The mileage reaches 350-500 thousand kilometers, which is a significant indicator.

Volkswagen diesels

Experienced motorists are trying to find out which best Volkswagen diesel engines have gone down in history and become a real legend. Representatives of one of the most famous automobile corporations in the world made every effort to please their admirers with a worthy offer.

Volkswagen employees carefully studied how fuel economy affects engine technical parameters, ride reliability, and control quality.

The 1.6 TDI engine is considered the best, because it was its technical parameters that allowed the power unit to take the golden mean. The model replaced the 1.9-liter modification, which was previously actively used.

The manufacturer did the following: the pressure in the fuel cylinders was increased while simultaneously saving fuel. The power characteristics were left the same: 90-120 horsepower.

Experts note that cars with a 1.6 TDI engine are ready to be among the most economical in the world. Official data shows: 3.3 liters of diesel fuel is required for every 100 kilometers. As you might guess, these indicators are among the most attractive.

The 1.6 TDI diesel engine is successfully used in the following cars:

• Golf hatchback;
• Tiguan crossover.

Subsidiaries of the automobile concern, namely Audi, Skoda, SEAT, actively use this engine. If you are wondering which diesel engine is better than an Audi, you can safely choose the 1.6 TDI version.

Toyota 3S-FE engines

Toyota 3S-FE is one of the most worthy engines, reliable and unpretentious. The Japanese development has managed to gain a high level of popularity thanks to the following parameters:

• 2 liter volume;
• 4 cylinders;
• 16 valves.

Despite typical characteristics, they became the basis for the development of a better diesel unit. In addition, the power indicator was truly pleasing: 128-140 horsepower. The parameters were sufficient for successful car trips.

The successful performance of the motor confirms its long production: 1986-2000. Subsequently, the engine was updated to two modifications: 3S-GE, 3S-GTE. Both updated versions are ready to please with a reliable design and a decent resource.

Diesel engines were installed on the following cars:

• Camry;
• Celice T200;
• Carina;
• Corona T170/T190;
• Avensis;
• RAV4;
• Picnic;
• Caldina;
• Altezza.

When wondering whether the Japanese manufacturer offers a good diesel engine for the Rav-4, one can note numerous positive responses. Even car experts note that the power unit is able to adequately withstand significant loads, with the result that serious breakdowns are surprisingly rare. Additional advantages include ease of repair and thoughtful design, which allows you to quickly repair any breakdowns. Good maintenance allows you to aim for a mileage of up to 500,000 kilometers without major repairs.

Despite the fact that many diesel units have gone down in history and have won an ideal reputation, you need to understand how they differ from gasoline engines.

Which is better, gasoline or diesel engines?

When studying the best diesel engines for passenger cars, it is important to understand what their advantages are. The usual comparison of gasoline and diesel units will help with this.

The use of diesel fuel immediately provides significant savings. This is due to the difference in compression ratio: diesel - 21 units, gasoline - 10. The compression ratio determines the efficiency, and therefore the fuel consumption, taking into account the distance covered. In addition, diesel engines provide for successful adjustment of the working mixture, guaranteeing the flow of the same amount of air into all cylinders. At the same time, even maximum power allows you to rely on a minimum volume of injected fuel, which leads to decent diesel economy.

The stability of diesel units is determined by the resistance air filter, affecting the air required to fill the cylinders. Correct adjustment of the injection start pressure allows you to increase the service life of engines. At the same time, diesel units require less adjustment than their gasoline competitors.

The reliability and stability of the engine is determined by the following aspects:

• air filter control;
• temperature at which the power unit operates.

Important! Initially, diesel engines have a long service life, since their elements are made of durable and rigid materials. The use of high-quality fuel with pronounced lubricating characteristics will allow the power unit to be used longer. Experts note that even the best diesel engine in the world requires a responsible approach to its maintenance.

Disadvantages of units may appear while the engines are running. The disadvantages include the large mass, less power compared to gasoline counterparts, noise due to high pressure in the cylinders used, difficult to start the machine at sub-zero temperatures. The risk of diesel engine malfunctions appears after the device has traveled 100,000 kilometers. Over time, engine components still wear out, so maintenance is as important as understanding the service life limit. Otherwise, the car will not be able to develop optimal power and speed. The most common reason for repairs is increased consumption oil, which can be determined by a change in the color of the smoke released from the exhaust pipe.

Summary

Recently, diesel engines have deservedly gained popularity. When wondering which diesel engine is better, it is advisable to pay attention only to the products of well-known automobile corporations. Only the best manufacturers offer reliable motors that allow you to develop optimal technical parameters in the shortest possible time.

Advantages of diesel engines:

• optimal power;
• resistance to traction forces;
• fuel economy;
• long service life thanks to a reliable and simple design;
• saving on fuel use.

Disadvantages are also present:

• difficulty starting the car at low air temperatures;
• the need to regularly change engine oil;
• increased requirements for the quality of fuel used.

When choosing the best diesel engine for your car, it is advisable to take into account the technical parameters that determine the possibility of using the engine. A unit that matches the car’s parameters becomes the best choice.

Japanese manufacturers have reliable diesel engines. And what is the most reliable diesel engine of all the reliable ones in Japan?

Let's look at the most common modern diesel engines in the Japanese automobile industry.

What are these diesel engines, what are the strengths and weaknesses of Japanese diesel engines. They now dominate mainly in Europe, but they have begun to appear quite often in Russia.

But, unfortunately, they also have problems when their mileage exceeds one hundred thousand kilometers, and even for some up to one hundred thousand.

The caution in the supply of diesel engines from Japan is due to their capricious attitude towards fuel. Their fuel system is quite weak to use our diesel fuel.

Another problem is the availability of spare parts. There are practically no non-original spare parts from reliable manufacturers. Chinese ones appear, but their quality leaves much to be desired and does not at all correspond to Japanese quality.

Hence their very high price, much higher than for German spare parts. There are many factories in Europe that produce spare parts of decent quality and at prices significantly lower than the original ones.

The most reliable diesel engine from Japan

So what is the most reliable diesel engine from Japan? Let's rank the TOP 5 best diesel engines.

5th place

In fifth place you can safely put the 2.0 liter Subaru engine. Four-cylinder, turbocharged, opposed, 16-valve. Common Rail intake system.

It must be said that this is the only boxer diesel engine in the world.

A boxer engine is when mutual pairs of pistons operate in a horizontal plane. This arrangement does not require careful balancing of the crankshafts.

Weak sides This engine, it is a dual-mass flywheel, it failed even before five thousand kilometers. Cracking crankshaft, until 2009, crankshafts and shaft supports were destroyed.

This engine is very interesting in its design, with good characteristics, but the lack of spare parts for such engines negates its advantages. Therefore, we give it the fifth place of honor in the Japanese range of diesel engines.

4th place

In fourth place we will place the Mazda 2.0 MZR-CD engine. This diesel engine began to be produced in 2002 and installed on Mazda car 6, Mazda 6, MPV. This was the first Mazda engine with a common rail system.

Four cylinders, 16 valves. Two versions - 121 hp. and 136 hp, both developing a torque of 310 Nm at 2000 rpm.

In 2005, it underwent modernization, with an improved injection system and a new injection pump. The compression ratio and adaptation of the engine with a catalyst for the emission of harmful gases have been reduced. Power became 143 hp.

Two years later, a version with a 140 hp engine was released; in 2011, this engine disappeared from the line of installed engines for unknown reasons.

This engine calmly nursed 200,000 kilometers, after which it was necessary to change the turbine and dual-mass flywheel.

When purchasing, you should carefully study its history, or better yet, remove the pan and look at the oil sump.

3rd place

Also a Mazda engine, Mazda 2.2 MZF-CD. The same engine, but with a larger volume. The engineers tried to eliminate all the shortcomings of the old two-liter engine.

In addition to the increased volume, the injection system was modernized and a different turbine was installed. On this engine they installed piezo injectors, changed the compression ratio and radically changed the particulate filter, which was the reason for all the problems of the previous model of the two-liter engine.

But the global struggle for the environment, both in Europe and in Japan, adds trouble to all engines, and this is where a system is installed, with the addition of urea to the diesel fuel mixture.

All this reduces emissions to Euro5, but as always, in Russia this adds problems to all modern diesel engines without exception. This is simply solved here: the particulate filter is thrown out and the valve for afterburning the unburnt exhaust is turned off.

Otherwise the engine is reliable and unpretentious

2nd place

Engine Toyota 2.0/2.2 D-4D.

The first two-liter Toyota 2.0 D-4D CD appeared in 2006. Four-cylinder, eight-valve, cast-iron block, timing belt drive, 116 hp. The engines came with the index “CD”.

Complaints about this engine were very rare, all of them were limited to the injectors and the exhaust gas recirculation system. In 2008, it was discontinued and replaced by a new one with a volume of 2.2 liters.

Toyota 2.0/2.2 D-4D AD

They have already begun to make it a chain one, there are already 16 valves for four cylinders. The block began to be made of aluminum with cast iron sleeves. The index of this engine became "AD".

The engines are available in both 2.0 liters and 2.2.

The most good feedback about such an engine, both good performance and low fuel consumption. But there were also complaints, the main one being the oxidation of the aluminum head at the point of contact with the cylinder head gasket, approximately in the period of 150-200 thousand km. mileage

Replacing the head gasket does not help, only grinding the cylinder head and block, and this procedure is only possible with engine removal. And such a repair is only possible once; the engine will not withstand the second grinding of the head and block, the depth will be critical with the possibility of the valves meeting the head. Therefore, if the engine has traveled 300-400 thousand kilometers, with one grinding, it should only be replaced. Although this is a very decent resource.

Toyota solved this problem in 2009; with such malfunctions, they even replaced the engines with new ones under warranty at their own expense. But the problem, very rarely, does occur. Mainly for those who are not weak in igniting the most powerful version of this 2.2-liter engine model.

Such engines are still produced and installed on various car models: Raf4, Avensis, Corolla, Lexus IS and others.

1 place

Honda 2.2 CDTi diesel engine. The most reliable small-displacement diesel engine. Very productive and very economical diesel engine.

Four-cylinder, 16-valve, variable displacement turbocharged, common rail injection system, lined aluminum block.

The injectors are used by Bosch, and not the capricious and expensive Japanese Denso ones.

The predecessor to this engine was built back in 2003, badged 2.2 i-CTDi. It turned out to be very successful. Hassle-free, dynamic and economical in fuel consumption.

Modern under consideration Honda engine The 2.2 CDTi appeared in 2008.

Of course, there were no typical malfunctions, but they were all extremely rare. Cracks in the exhaust manifold, but they appeared in the first editions, the Japanese reacted and this did not occur in subsequent editions.

Sometimes there were malfunctions of the timing chain tensioner. Also, sometimes the turbine shaft play appeared prematurely.

All these malfunctions arose from excessive constant loads and poor maintenance.

Honda installed this engine on Honda Civic, Accord, CR-V and others.

Of course, this engine has the lowest number of failures and breakdowns compared to all other engines from Japanese automakers.

We give it five points out of five, assign it the first place of honor and wish you to have a similar one in your car.
