Indestructible diesel engine. The best gasoline engines

Long gone are the days when diesel fuel was used only on ships and in heavy trucks. Now this type of fuel has become an integral attribute of modern passenger car. And the current units have nothing to do with the engines produced in the past, which were distinguished by slowness, low power, an unpleasant smell of diesel fuel and black burning.

Modern diesel engines are very different from their ancestors.

The first appeared in the pre-war period. They were too noisy, demanding on quality fuel and needed frequent maintenance which was costly. Modern engines running on such fuel are quite economical and have high power. They are able to make life easier for their owner and bring him a lot of advantages.

Engine differences

Consider how the units operating on different fuels differ from each other.

Motors are aggregates internal combustion. The compressed air-fuel mixture in the cylinders is ignited by a spark. Such engines are divided as follows:

• injection - gasoline is supplied to a common pipeline using one or more injectors;
• carburetor - the process of mixing air and fuel begins, and ends in the intake manifold;
• injection of fuel directly into the combustion chamber allows the engine to work even on lean mixtures and optimizes the combustion process.

These are internal combustion units equipped with a piston system. The principle of operation of such a motor is somewhat different. The ignition of the atomized fuel occurs after its contact with heated air. Makes diesel units more economical, unlike their gasoline counterparts, a high degree of fuel compression. Diesel engines do not have a throttle valve, which does not reduce fuel consumption.

Advantages of diesel engines

The first diesel engines for passenger cars mobiles were simply reduced copies of motors that were installed on heavy ones. Thanks to innovative engineering solutions modern diesel engines unique characteristics and become quieter and more powerful. Cars diesel cars now popular and in demand. The following are their main advantages:

• The efficiency of a diesel engine is higher than that of its gasoline-powered counterpart. It converts 36% of the fuel energy into useful energy, and only 26% for a gasoline unit;
• the likelihood of fire is significantly lower than that of gasoline options;
• the cost of fuel is lower than the price of gasoline;
• efficiency - fuel consumption is 25% lower than gasoline;
• low toxicity of exhaust gases does not pollute the environment;
• lack of an ignition system;
• endurance of a diesel engine, and, accordingly, its long work, in contrast to gasoline units;
• high power acceleration speed due to the presence of a turbocharger;
• fuel acts as an oil, lubricating the main parts of the engine;
• water resistance, unpretentiousness and universal cross-country ability in off-road conditions;
• popularity.

Of course, it cannot be said that the diesel engine is so perfect and does not have any shortcomings. Among the shortcomings can be noted:

• diesel fuel has a lower freezing point than gasoline;
• quite noisy operation of the unit at idle;
• high cost of spare parts;
• a high power starter is required;
• engine sensitivity to low-quality and dirty fuel;
• before starting the engine, you have to wait until the combustion chamber warms up;
• the diesel unit is not designed to operate at high speeds;
• in winter, you can not use the "summer" diesel fuel;
• V very coldy due to insufficient compression, starting the engine will be quite problematic.

best diesel car engine

It has already been proven that diesel engines are more reliable, durable and economical. All the best diesel engines can be divided into the following areas:

1. American - Chrysler and Ford. These manufacturers are constantly working to reduce fuel consumption and rely on the power and performance of their units.
2. German - Mercedes and BMW. High technological performance of engines and excellent quality of products. Distinctive features are excellent dynamic characteristics and maximum reliability.
3. Asian - Toyota and Hyundai. The products of these brands are distinguished by reliability, high dynamic performance and productivity.

We will figure out which of the diesel engines is the best.

The OM602 diesel engine from Mercedes is a real legend. It has already been discontinued, but diesel-fueled vehicles equipped with such an engine will continue to drive on the roads of the world for a long time to come. This is due to the fact that the service life of this unit is estimated at a million kilometers. If you properly take care of the fuel system of the vehicle, then the engine will certainly be able to drive up to two million kilometers.

The N57 engine from BMW has a volume of 3 liters and 6 cylinders. Such indicators make this unit a champion in its niche. It is installed on sedans of the 5th and 7th series and full-size crossovers. For all its power, the engine is quite economical. Permanent care for the fuel system and purchase exclusively quality fuel will allow you to drive up to 200-250 thousand km without problems.

Chrysler's Cummins turbodiesel has a power of 275 Horse power. It is aggressive and at the same time very economical. The heads of this engine are cast from a new alloy, which allows us to consider it an environmentally friendly unit.

The Asian U2 14 is the best fit for Russian motorists. It has a simpler design, reliable and unpretentious. It gives pretty decent performance and at the same time is resistant to low-quality fuels and lubricants.

The best diesel cars of 2015

• Favorite diesel market considered a car business class Volkswagen Passat. He is able to accelerate in 7 seconds to a speed of 100 km / h. There are also budget options, with less power, but affordable for many at a price.

• Family Skoda car Octavia has been unrivaled since 1996. It is equipped with a 1.9 liter engine.

• Ford Focus 3 is ideally suited for city driving. There are options that, on the contrary, are ideal for the track. The choice is up to the consumer.

• Ford Fiesta is a fairly compact car that has a lot of modifications. It can be equipped with a 1.4 or 1.6 liter diesel engine. Great for both city driving and highway driving. real model is different affordable cost and attractive appearance.

• Volkswagen Golf is the best diesel car in the middle class. In terms of sales, it leads the world market. It can be equipped with different options for turbocharged engines with a volume of 1.6 to 2 liters. This brand has high power along with excellent fuel economy.

• The BMW 3-Series is the perfect solution for a business person. The lineup includes several options for machines that are different in power and other parameters. Each consumer will be able to determine the best option for himself.

The best

Diesel-powered vehicles may differ in power, economy and other characteristics. There are many ratings that call the best completely different vehicles. And this is an absolutely normal phenomenon, because everything depends on the audience being surveyed, the territory of the survey and the number of respondents. And the opinions of amateurs and experts also often have cardinal differences.

It is worth noting that the opinions of many experts and ordinary drivers agreed on the issue of determining the best diesel passenger car. The championship was unanimously given to the Volkswagen Golf. The car is considered comfortable, economical and reliable. It is equipped with 8-10 airbags.

Most best crossover- Range Rover Evoque. It is considered practical and prestigious at the same time. It has a simplified configuration, excellent power and a high degree of safety. There is a version with three doors. It has a lighter weight and increased rigidity of the body, thereby optimizing the handling of the vehicle.

The most powerful passenger car with a diesel engine can be called the Audi Q7. It is equipped with a 12-cylinder engine with a volume of 6 liters. Its power reaches 500 horsepower. Despite the weight of 2.5 tons, this car is able to compete with modern sports cars. Up to 100 km / h, the car accelerates in just 5.5 seconds. This model is not available for free sale, but is made exclusively to order.

The best diesel-powered vehicles aren't always the most agile and capable of delivering high speed. The fastest of them is BMW crossover X6. It has an engine with 6 cylinders and a volume of 3 liters. The presence of three turbines allows a car with a capacity of 381 horsepower to accelerate to 100 km in just 5.2 seconds. Max Speed this car reaches 290 km / h. Manufacturers don't stop there. They plan to release a car with four turbines in the future, the power of which will reach 390 horsepower.

The best diesel vehicles tend to have low fuel consumption. The most economical of them is the Seat Ecomotive. Fuel consumption is only 3.3 liters per 100 km in mixed mode. Despite the fact that the engine has a volume of only 1.2 liters, it cannot be called weak. Vehicles in the Ecomotive configuration, they can reach speeds of up to 175 km / h and accelerate to 100 km / h in 13 seconds.

Summing up all of the above, we can say that the future of the automotive industry lies with diesel engines. They are durable, reliable and economical. However, recently it turned out that in their exhausts there are substances that can cause cancer in humans. Therefore, engineers of world manufacturers will have to work hard and develop filters that would capture harmful substances and did not release them into the atmosphere.

Which engines are the best - German, Japanese or maybe American? We have ranked the most successful motors and revealed the secrets of their reliability and "indestructibility".

Car owners have a legend. About an engine that doesn't break down. And not just one, but many. These legends are overgrown with amazing biographies over time, giving rise to unceasing disputes on the topic "German versus Japanese versus American."

Many eyewitnesses are ready to testify to the reliability of this or that motor with a mileage of half a million to a million kilometers, not in the least embarrassed by the fact that its origin is hidden in the darkness of centuries, and it has been observed by eyewitnesses for several years at most. But the legends do not lie: such engines exist. We have combined them into a list, in the preparation of which we provided all possible assistance to auto mechanics with a solid work experience.

The list turned out to be rather big - over the past few decades, automakers have managed to create enough masterpieces of engine building. And we will make a reservation that not all motors will be included in our review, but only ten, the most famous and massive ones. Those that were installed on the iconic models of their time won races. Some kind of celebrity in the world of cars.

Diesels

Diesel power plants traditionally considered the most reliable. Largely due to the fact that ten years ago it was difficult to imagine a car with a sporty character and diesel unit, and even now diesels are taken by those who need to travel a lot, which means that the engine works in the best conditions. In addition, older generations of engines have a relatively simple design with a good margin of safety.

Mercedes-Benz OM602

The family of OM602 diesel engines, five-cylinder, with two valves per cylinder and a Bosch mechanical injection pump deservedly holds the palm in terms of mileage, resistance to life's difficulties and the number of cars left on the move with them. These diesels were produced from 1985 to 2002 - almost twenty years.

Not the most powerful, from 90 to 130 hp, they were famous for their reliability and efficiency. This family had quite worthy ancestors, the OM617 generation, and quite worthy successors - OM612 and OM647.

You can meet such motors on Mercedes in the back of W124, W201 (MB190), on G-class SUVs, on T1 and Sprinter vans, and even on later W210s. The runs of many instances exceed half a million kilometers, and the record ones - in two. And if you take care of the failing fuel equipment and attachments in time, then the design will not let you down.

BMW M57

Bavarian engines are no less deserved than Stuttgart ones. These in-line six-cylinder diesels, in addition to impressive reliability, were also distinguished by a very lively disposition, contributing a lot to changing the image of the diesel engine. It is no longer possible to perceive the BMW 330D in the E46 body as a slow car for pensioners or taxi drivers, it is a driver car, but with a powerful and high-torque diesel engine.

The power of these motors in different versions ranged from 201 hp. up to 286 hp, and they were produced from 1998 to 2008 and were on most Bavarian models of the decade. All of them, from the third series to the seventh, had variants with the M57. They are also found on the Range Rover - the engine of the legendary Mumusik was from this series.

By the way, our hero had a no less legendary ancestor, albeit not so common. The M51 engine family was produced from 1991 to 2000. petty problems the engines had enough, but the mechanics are unanimous: serious breakdowns are rare and it “runs” well, at least up to runs of 350-500 thousand.

Petrol in-line fours

Petrol engines in Russia are still loved more than diesel ones. Still, gasoline does not freeze in winter, and they are simpler. And if the diesel engines in the list of finalists turned out to be only relatively large, then among the gasoline “legends” there will be smaller engines, the usual in-line “fours”.

Toyota 3S-FE

The honor to open the list falls to the Toyta 3S-FE motor, a representative of the well-deserved S series, which is considered one of the most reliable and unpretentious units in it. A two-liter volume, four cylinders and sixteen valves are typical indicators for mass engines of the 90s. Camshaft drive by belt, simple distributed injection. The engine was produced from 1986 to 2000.

Power ranged from 128 to 140 hp. More powerful versions of this engine, 3S-GE and turbocharged 3S-GTE, inherited a successful design and a good resource. The 3S-FE engine was installed on whole line Toyota models: Toyota Camry(1987-1991), Toyota Celica T200, Toyota Carina (1987-1998), Toyota Corona T170 / T190, Toyota Avensis (1997-2000), Toyota RAV4 (1994-2000), Toyota Picnic (1996-2002), Toyota MR2, and turbocharged 3S-GTE also on Toyota Caldina, Toyota Altezza.

Mechanics note the amazing ability of this engine to endure high loads and poor service, the convenience of its repair and the overall thoughtfulness of the design. At good service such motors exchange a mileage of 500 thousand kilometers without major repairs and with a good margin for the future. And they know how not to bother the owners with minor problems.

Mitsubishi 4G63

Another epic Japanese family of two-liter gasoline engines. Its first variants appeared in 1982, and licensed copies and successor models are still being produced. Initially, the engine was produced with one camshaft(SOHC) and three valves per cylinder, but in 1987 a DOHC version with two camshafts appeared. The latest varieties of the unit were installed on Mitsubishi Lancer evolution IX until 2006. The motors of the family found a place under the hood not only Mitsubishi machines but also Hyundai, Kia as well Chinese brand Brilliance.

Over the years of production, the engine has been repeatedly upgraded, its most recent versions have a timing system for adjusting the timing and more complex power and boost systems. All this does not affect reliability in the best way, but maintainability and ease of layout remain. Only naturally aspirated versions of the engine are considered “millionaires”, although turbocharged ones can also have a very large resource, by the standards of competitors.

Honda D series

Another Japanese family of engines, which includes more than a dozen varieties with a volume from 1.2 to 1.7 liters, which have rightfully earned the status of practically “indestructible”. They were produced from 1984 to 2005. The D15 and D16 options are considered the most reliable, but they all have one thing in common - the will to live and high tachometer readings.

Power reaches 131 hp, and operating speed - up to 7 thousand. Such motors were installed on the Honda Civic, HR-V, Stream, Accord and Acura Integra. With a combat nature and a small working volume, the resource before overhaul of 350-500 thousand can be considered outstanding, and the well-thought-out design gives chances for a second life and another 350 thousand mileage.

Opel 20ne

The list of excellent and simple “fours” is closed by the representative of the European school of engine building - x20se from the Opel 20ne engine family. This member of the GM Family II engine family became famous for often outliving the cars it was installed on.

Simple design- 8 valves, camshaft belt drive - and simple system multipoint injection are the secrets to longevity. Like the most successful examples of the Japanese school, it has a volume of two liters and the same ratio of bore and piston stroke as on the 3S-FE - 86 x 86mm.

Power different options ranges from 114 to 130 hp. Motors were produced from 1987 to 1999 and installed on models such as Kadett, Astra, Vectra, Omega, Frontera, Calibra, as well as Australian Holden and American Buick and Oldsmobile. In Brazil, they even produced a turbocharged version of the engine - Lt3 with a capacity of 165 hp.

The sixteen-valve version, the famous C20XE, was used on Lada and Chevrolet cars in the WTCC racing championship until last year (we talk about the successes of the AvtoVAZ factory team), and its turbocharged version, C20LET, managed to be noted in the rally and is considered one of the simplest and most successful.

Simple versions of the engine can exchange not only half a million mileage without a major overhaul, but with a careful attitude, they will try to go for a million. Sixteen-valve varieties, X20XEV and C20XE, do not have such “health”, but they can also please the owner for a long time, and their design is just as simple and logical.

V-shaped "eight"

V8 motors for cars usually they do not differ in an extra-long resource - the lightweight design and the complexity of the layout of such big motor do not add reliability to the unit as a whole. This does not quite apply to American V8s, but they are a separate conversation.

Really reliable V-shaped motors, which do not annoy the owners with large and small breakdowns, can easily cross the threshold of half a million kilometers, can be counted on the fingers.

BMW M60

And again in the list of reliable motors - Bavarian products. The company made the first passenger car V8 in many years to fame: double row chain, nickel-plated cylinders and a good margin of safety. A relatively small degree of forcing and a good design study made it possible to create a truly resourceful motor.

The use of a nickel-silicon coating (Nikasil) makes the cylinders of such a motor virtually wear-free. By half a million kilometers, often the engine does not even need to be changed piston rings. But such a durable nickel coating is afraid of sulfur in the fuel, and after numerous cases of engine damage in the USA, its use was abandoned in favor of Alusil technology, with a more “gentle” coating. Despite the same high hardness, it crumbles over time under the influence of shock loads and other factors. These motors were installed on the BMW 5th and 7th series models in 1992-1998.

Simplicity of design, high power, a good margin of safety allows them to cover more than half a million kilometers. Unless, of course, you run on high-sulfur Canadian gasoline... Later engines, the M62, have become much more complex and, as a result, much less reliable. They can compete in terms of resource before overhaul, but not in terms of the number of breakdowns. Early versions of the M62 also used a nikasil coating, later replaced by alusil.

Petrol in-line "sixes"

Surprisingly, it is a fact: there are a lot of in-line six-cylinder engines among millionaires. Relatively simple design, balance (and therefore lack of vibration) and power bear fruit in the form of reliability and resource.

Toyota 1JZ-GE and 2JZ-GE

These 2.5 and 3 liter engines have earned the right to be called legendary. An excellent resource with a very lively character - this is the formula for success. They were produced from 1990 to 2007 in various versions. There were also turbocharged versions of them - 1JZ-GTE and 2JZ-GTE.

In Russia, they are best known in the Far East due to the prevalence of right-hand drive "Japanese". Among others, 1JZ and 2JZ were installed on Toyota Mark II, Soarer, Supra, Crown, Chaser, as well as the American Lexus Is 300, GS300, which are incomparably less common in our country. By the way, we wrote about right-hand drive legends of the 90s in ours.

For the attention of motorists are presented most reliable car engines according to experts.

Powertrain Series AWM open the top ten most reliable motors for cars. They were first created in 1987 and still these motors enjoy unprecedented popularity on many cars. German made- Volkswagen, Audi and many others. AWM are durable, reliable and unpretentious. by the most powerful engines from the AWM series are APG and AWA motors. The first engine is eight-valve with Digifant injection. Its volume is 1.8 liters, the power is high - 160 hp. with a torque of 228 Nm / 3800 rpm. This power unit has found the widest application in Volkswagen cars Passat B5. The second motor is a much larger volume - 2.8l. At the same time, its power is 175 hp. at 240 Nm/4000 rpm

Mercedes M266 is one of the most reliable engines for passenger cars. The 4-cylinder petrol engine is an evolution of the previous M166, known from the first A-Class and Vaneo. The engine received a specific design, as it had to be placed at a large slope in a close engine compartment. The engineers relied on simplicity: only one timing chain and 8-valve gas distribution mechanism. Mechanical very reliable. Injector malfunctions are very rare.

Suzuki DOHC M

Engines Suzuki DOHC"M" located on the eighth line in the list of the most reliable engines. The power units of the "M" series include small-capacity motors 1.3, 1.5, 1.6 and 1.8. The latter is exclusively for the Australian market. On the European continent, the power unit is found in almost all small and medium Suzuki models that appeared at the turn of the 20th and 21st centuries, and in the Fiat Sedici 1.6, which is a copy of the Suzuki SX4. The mechanical part of the engine is very reliable and durable. Even the phase change system is not satisfactory VVT valve timing used by most engine modifications. It is not only in the 1.3-liter version, designed for Ignis and Jimny until 2005, and the old 1.5 modifications for the SX4. chain drive Timing belt is very reliable. Among the minor drawbacks, small oil leaks through the crankshaft oil seal can be noted. More serious malfunctions practically do not occur.

Honda D— series ranked seventh in the top of the most reliable engines for passenger cars. Honda's D-series is, first of all, the legendary D15B and all their modifications. First of all, it is worth considering precisely these motors, which had greatest influence on the development of single-shaft engines in the world. The Honda D-series engine is an almost perfect design. Transversely installed in engine compartment inline four, rotating according to the “laws of Honda”, counterclockwise with a belt drive. The fuel mixture was supplied through a carburetor, through two carburetors (a unique development from Honda), through a mono-injection system (supply of atomized fuel to intake manifold), and injection feed. Moreover, all these options met simultaneously in one model. The reliability of this series has become the standard for simple single-shaft engines. They were produced from 1984 to 2005.

Mitsubishi 4 G63 is one of the best and most reliable motors for a passenger car. The first modification 4G63 appeared back in 1981, and continues to be produced to this day with minor changes. Excellent specifications of this motor are combined with its excellent reliability. Engines of the 4G63 family are four-cylinder power units that have a volume of 2.0 liters and power from 109 to 144 horsepower. The 4g63 engine has cast iron block cylinders and an aluminum head, which allows for maximum resistance to overheating.

Toyota 3 S— F.E.- one of the most reliable engines for passenger cars. Modification 3S FE was one of the first Toyota with a direct fuel injection system. The use of an injector made it possible to significantly improve the power characteristics of the new engine, its idling speed improved, and fuel consumption was significantly reduced in comparison with the carburetor version of this engine. Myself Toyota engine The 3S FE is actually an upgraded version of the 3S, so it retains its legendary reliability and relative simplicity of design. A feature of this power unit is the presence of two ignition coils, which improves the quality of flammability fuel-air mixture. The 3S engine works confidently on 92 and 95 gasoline. Depending on its version, the power indicator can range from 115 to 130 horsepower. The motor shows the maximum torque already from the very bottom, so the car owners did not experience a lack of traction.

Included in the top ten most reliable engines for passenger cars. This member of the GM Family II engine family became famous for often outliving the cars it was installed on. Simple design: 8 valves, camshaft belt drive and a simple port injection system are the secrets of longevity. The power of different options ranges from 114 to 130 hp. Motors were produced from 1987 to 1999 and installed on models such as Kadett, Astra, Vectra, Omega, Frontera, Calibra, as well as Australian Holden and American Buick and Oldsmobile. In Brazil, they even produced a turbocharged version of the engine - Lt3 with a capacity of 165 hp.

BMW M60

bmw M60 opens the top three most “indestructible” engines for a passenger car. The use of a nickel-silicon coating (Nikasil) makes the cylinders of such a motor virtually wear-free. By half a million kilometers, it is often not necessary to change even the piston rings in the engine. Simplicity of design, high power, good margin of safety puts the M60 among the best.

bmw M57 included in the list of the most reliable engines for passenger cars. The power unit was designed by BMW and its production began in 1998. The motor has several of its modifications, changes and improvements were made as performance was studied, and not all implemented engineering improvements had the same effect on the reliability of the unit. The main innovation of this engine was the common rail diesel fuel injection system, with which it was possible to achieve high performance engine operation. An important characteristic of all M57 engines is their ability to provide high torque at low crankshaft speeds (exact data depends on the modification) and average values maximum speed, which led to an increase in the service life.

Mercedes— Benz OM602 tops the ranking of the most reliable passenger car engines. In 1985 Mercedes company Benz introduced the OM602 diesel engine for a passenger car that stood out highest reliability and took its place in the history of the automotive industry. The resource of this 5-cylinder diesel engine was more than 500,000 km, there were cases when cars with such an engine traveled more than 1 million kilometers without engine overhaul. In 1996, they released a new modification of the OM602 engine called OM602.982 with direct fuel injection and a power of 129 horsepower. This diesel engine had unique fuel economy characteristics (7.9 l/100 km urban for the C class), significant torque at low revs and was fairly quiet despite direct injection.

Production: since 1993 - 1.2 liters, since 2003 - 1.4 liters.

Application: Fiat Punto/Grande Punto/Punto Evo, Fiat 500, Fiat Panda, Fiat Idea, Fiat Palio, Ford Ka (2nd generation), Fiat Linea, Lancia Musa, Lancia Y.

Fiat's engines of the FIRE series (Fully Integrated Robotised Engine - an engine completely assembled by robots) for more than 30 years. The range of power units covers a wide range of engines with a working volume from 769 cm3 to 1368 cm3, and 8-valve versions were later supplemented with 16-valve ones. Two 8-valve units without hydraulic pushers are worthy of attention.

In general, all versions of engines with an 8-valve head, regardless of the displacement, turned out to be very durable. The simple design showed high wear resistance even in small displacement engines (eg 1.1). Outdated 8-valve versions after a timing belt break will not require a major overhaul, which is inevitable for more modern modifications, which have a higher compression ratio and comply with Euro-5 standards.

FIRE engines have always been characterized by "plasticity" of character. Incredibly, two absolutely identical motors after running in behaved completely differently. So with calm drivers, he behaved lazily, and with temperamental drivers, he behaved more briskly.

Regular maintenance involves changing the timing belt, spark plugs and a reasonable oil change interval (in Europe it is a maximum of 15,000 km). These engines are absolutely reliable - they can only occasionally be disturbed by minor oil leaks.

Ford 1.38VDuratecRocam"

Production: 2001-2008

Application: Ford Ka (1st generation), Ford Fiesta VI.

The engine is similar in design and parameters to the older 1.3 OHV. It has a cast iron block, timing chain and hydraulic tappets. The power unit is rather lazy, but absolutely reliable. It has good traction at low revs and requires minimal operating costs. The motor was assembled in Brazil and South Africa (South Africa). The abbreviation Rocam stands for Shaft with Roller Bearings.

Along with the ancient OHC "Pinto" unit (used, for example, in the Ford Sierra), this is one of the most reliable engines that has ever been under the hood of a Ford. The larger 1.6L Rocams are much rarer. They were used mainly in the "charged" Ford SportKa and Ford StreetKa.

Honda 2.2i-DTEC

Production: 2008-2015.

Application: Honda Accord 8th generation, Honda CR-V 3rd generation, Honda Civic - 9th generation.

In fact, 98% of Honda's gasoline units could be listed here, and no one would object. But much more interesting is the fact that the Japanese diesel engine turned out to be very reliable. And this despite the fact that its design uses all the most vulnerable elements of modern diesel engines, which the best of competitors cannot cope with.

Using a single-row timing chain is completely counterproductive, not to mention a thermally unstable aluminum block with thin, dry steel cylinder inserts (complicating heat dissipation) - any connoisseur will tell you BMW diesel N47.

In 2.2 i-DTEC, such a set works properly for a long time. Even the piezoelectric injectors, the turbocharger (has water-cooled bearings) and the electrically controlled EGR valve do not cause problems. The normally carbonized swirl flaps in the intake manifold have been replaced bypass valve at the entrance to the bifurcated intake duct, and the EGR was "connected" behind it.

The only known drawback is the failure of the differential pressure sensor of the DPF filter.

Mercedes M266 (1.5/1.7/2.0)

Production: 2004-2012.

Application: Mercedes A-Class (W/C 169), mercedes b-class(T 245).

Strong and reliable diesel engines from OM601 to OM606 are known from the legendary W124. But they are long out of date. However, among the newer units you can find a hardy motor. This is M266. The 4-cylinder petrol engine is an evolution of the previous M166, known from the first A-Class and Vaneo.

The engine received a specific design, as it had to be placed at a large slope in a cramped engine compartment. The engineers relied on simplicity: only one timing chain and 8-valve gas distribution mechanism.

The mechanical part is very reliable. Injector failures are very rare (which is somewhat surprising for an indirect injection gasoline engine). But in most cases, the defect manifested itself during the warranty period.

All three versions of the motor are very hardy. The presence of turbocharging for modifications of the A200 Turbo theoretically increases the likelihood of malfunctions, but in reality nothing of the kind happens. The disadvantages include slightly increased fuel consumption, but this merit is not enough good aerodynamics of the body.

Mitsubishi 1.3/1.5/1.6MIVEC (series 4A9)

Production: since 2004.

Application: Mitsubishi Colt, Mitsubishi Lancer, Mitsubishi ASX, Smart ForFour, Citroën C4 Aircross.

Almost all gasoline engines Mitsubishi is very reliable, so choosing the best one is not easy. One of the most common is the 4-cylinder unit of the 4A9 series. It was created in a Mitsubishi/Daimler-Chrysler collaboration and is one of the most reliable engines on the market today.

4A9 is made entirely of aluminum, has a 16-valve DOHC gas distribution system, a variable valve timing system intake valves With electronic control MIVEC (some versions of the engine with a working volume of 1.3 liters are deprived of it). Although the engine is over 10 years old, no problems are known. Cars with such engines come to the service only for maintenance - replacement, oil, filters and candles.

4A9 is only atmospheric. Turbocharged Colt CZT/Ralliart models use a completely different Mitsubishi "Orion" engine. The Citroen C4 Aircross inherited the engine from its tech twin, the Mitsubishi ASX 1.6 MIVEC, but sold it under the simple name 1.6 i, and in some markets even the downright amazing 1.6 VTi.

PSA 1.4HDi 8V(DV4)

Production: since 2001.

Application: Citroen C1, C2 Citroen, Citroen C3, Citroen Nemo, Peugeot 107, Peugeot 1007, Peugeot 206, Peugeot 207, Peugeot Bipper, Toyota Aygo, Ford Fiesta, Ford Fusion Mazda 2.

The small 1.4 HDi can be seen as the successor to the legendary XUD7/XUD9. Even despite the fact that "on paper" the 1.4 HDi was created in collaboration with Ford (as was the larger 1.6 HDi). In fact, this is a completely French design, which turned out to be very successful.

Like Honda, the French were able to create a solid aluminum block with dry inserts. The timing belt is capable of going 240,000 km or 10 years. A simple turbocharger will last forever. The common rail injection system from Siemens has proven itself right from the start. Mazda, Ford and some PSA models have recently mentioned the Bosch injection system.

Initiates know that there is also a 16-valve version with a return of 90 hp. for more powerful options - Citroen C3 1.4 HDi and Suzuki Liana 1.4 DDiS. With its leaky 16-valve head, variable geometry turbocharger and Delphi injection system, this engine will never match the simple 8-valve version in terms of reliability.

Subaru 3.0 / 3.6R6 (EZ30 /EZ36)

Production: since 2000.

Application: Subaru Legacy, Subaru Outback, Subaru Tribeca.

Of all the illustrious Subaru boxers, the most reliable are the naturally aspirated six-cylinder EZ series, known from the Outback, Legacy 3.0R and the Tribeca crossover. The first versions of the 3-liter Outback H6 (219 hp until 2002) still had mechanical drive throttle control and aluminum intake manifold. Later modifications (245 hp), despite more sophisticated technologies (among others, the system for regulating the height of the lift and the phases of the intake valves, and in 3.6 also the exhaust ones), did not become more “vulnerable”.

The engine has so-called wet cylinder liners and a durable timing chain. The only real downside is the relatively high level fuel consumption (especially in the Legacy 3.0 Spec B equipped with a sports manual with a short-stroke gear selector) and minor maintenance difficulties (for example, to change spark plugs due to poor accessibility to the "horizontal" cylinders).

Suzuki 1.3/1.5/1.6DOHCM"

Production: since 2000.

Application: Suzuki Jimny, Suzuki Swift, Suzuki Ignis, Suzuki SX4, Suzuki Liana, Suzuki Grand Vitara(1.6), Fiat Sedici (1.6), Subaru Justy III.

M series engines include 1.3, 1.5, 1.6 and 1.8 small capacity motors. The latter is exclusively for the Australian market. On the European continent, the power unit is found in almost all small and medium Suzuki models that appeared at the turn of our millennium, and in the Fiat Sedici 1.6, which is a copy of the Suzuki SX4. The mechanical part of the engine is very reliable and durable. Even the VVT ​​variable valve timing system, which is used by most engine modifications, is not satisfactory. It is not only in the 1.3-liter version, designed for Ignis and Jimny until 2005, and the old 1.5 modifications for the SX4.

The timing chain drive is reliable. Among the minor drawbacks, small oil leaks through the crankshaft oil seal can be noted. More serious malfunctions are almost never encountered.

Toyota 1.51NZ-FXE Hybrid

Production: since 1997.

Application: Toyota Prius I, Toyota Prius II, Toyota Yaris III Hybrid.

As with Honda, this review almost all Toyota engines could get in, but let's focus on the hybrid, which is still perceived by most motorists with skepticism. And this despite the fact that this power unit has unprecedented reliability. A simple high compression gasoline engine operating on the Atkinson cycle, a synchronous electric motor with permanent magnet and nothing more.

There are no gearboxes in the classical sense, and therefore there are no problems with this device. Instead, it uses planetary reductor with two inputs and one output. gear ratio varies depending on the difference in the speeds of rotation of both engines.

The most frightening thing is the expensive battery. But so far none of the owners have changed it. European competitors cannot match the phenomenal Japanese reliability.

Volkswagen 1.9SDI /TDI

Production: 1991-2006 (in some markets until 2010).

Application: Audi 80 B4, Audi A4 (1st generation), Audi A3 (1st generation), Audi 100/A6 (C4), Audi A6 (C5), Seat Alhambra, Seat Ibiza, Seat Cordoba, Seat Inca, Seat Leon, Seat Toledo, VW Caddy, VW Polo, VW Golf, VW Vento, VW Bora, VW Passat, VW Sharan, VW Transporter, Ford Galaxy(1st generation), Škoda Fabia and Škoda Octavia (1st generation).

Without a doubt, this is one of the most famous, but perhaps the most controversial engine on our list. The SDI/TDI engines are based on the old 1.9 D/TD. They received direct injection, thermal loads on the head of the block were reduced and a Bosch rotary pump was installed, however, it is sensitive to fuel quality.

The reliability and durability, especially of the simple naturally aspirated 1.9 SDI versions, deserves respect. The engine is able to cover more than one million kilometers without major investments. Commonly Mentioned Sensor Issues mass flow air is not taken into account.

Paradoxically, the most reliable turbocharged option is only the 90 PS TDI with a maximum torque of 202 Nm (code designation 1Z or AHU). This turbodiesel appeared in the early nineties and was used in Audi, Golf III, Passat B4, Seat until 1996-1997.

Among the Skoda Octavia, the CMA is considered the best TDI. Its small, fixed-geometry turbocharger exhibits much greater survivability than the supercharger of a 90-horsepower ALH with variable geometry. The latter was prone to blade sticking, just like the 110 hp version.

The only thing weakness SDI / TDI, especially in the early years of production - crankshaft damper pulley.
