If you know about "dieselgate" and the scandal with heavy fuel engines in Germany, then you are already rubbing your hands in anticipation of very cheap cars on the Russian market. Diesel cars have shown their inability to meet environmental regulations and requirements. But in Russia this indicator is not taken into account as strictly as in Europe and the USA. There, the environment has become the main means of speculation by politicians and corruption schemes, while in our country reality is assessed much more adequately. It's time to think about which diesel engines to consider for purchase. Manufacturers' catalogs contain dozens of motors with different characteristics that fully meet the requirements for reliability and confidence of movement. Today we will figure out who is the manufacturer of the most reliable diesel engine with high potential and certain advantages over rivals.
Find the best technical solution not so easy. Among all modern technologies even a few worthy units are not easy to choose. On the one hand, German diesels show good opportunities. On the other hand, branded french cars on heavy fuel also do not lag behind in technology, reliability and operational capabilities. The question is not only who the manufacturer is, but also when the unit was developed. There are dozens of criteria worth considering in this aspect. But most of them are purely technical, so for a non-specialist in the production or maintenance of cars, such numbers will not say anything. Let's look at a few of the most successful motors that actually have the right features to buy. In this case, you can easily choose a decent option without a lengthy comparison.
Volkswagen 2.0 TDI Common Rail 140 HP
Talk about German diesels 2 liters is somehow not accepted in modern automotive society. Journalists politely walk away from the conversation, experts shake their heads disapprovingly. It was this unit that caused all the problems of a diesel nature in the USA and Europe. But in other countries they are happy to buy it today. The machine with the unit in the 140 horsepower version has the following pleasant characteristics for the owner:
- 140 horsepower and a very noticeable torque from the lowest revs give simply amazing dynamics and excellent power that is felt when driving a car;
- fuel consumption on the Passat, for example, in the city is kept within 7.5 liters per 100 km, and on the highway, diesel consumption drops to 5 liters per hundred, which is confirmed on average by logbooks;
- the elasticity of work is excellent, it is immediately felt that the most famous diesel engineers world, and the motor inherited its abilities from a huge series;
- reliability has been proven by millions of buyers around the world, reviews of the 2.0 TDI engine from Volkswagen are very surprising, which contributes to their active sale to this day;
- maintenance is not as expensive as for other diesel engines of many other concerns, the engine design is not so simple, but special attention it does not require operation.
This is the main data about the engine with a volume of 2 liters and a potential of 140 horses. There are versions of this unit even with 110 hp, which were installed on Caddy and other cars without significant power requirements. But in fact, it is the 140 hp device. demonstrates its readiness for modern conditions operation. The motor will delight you with its qualities and the ability to work in all modes.
Renault 2.0 DCI 177 horses - super motor
New Renault diesel engine developed for Koleos current generation. At first it was believed that diesel would not be supplied to Russia, selling it only in Europe. But it turned out that Europeans are quickly losing interest in heavy fuel and cars with engines running on such fuel, so Russia got additional equipment in the crossover range. The engine has the following interesting characteristics:
- a simple 2-liter volume and a very groovy 177 horsepower pull a large crossover well, accelerating it to 100 km / h in 9.5 seconds, which is very good in this segment;
- torque of 380 N * m is already available at 2000 rpm, traction is simply magnificent, from the very bottom the engine works perfectly and follows all the instructions of the driver;
- fuel consumption in the city according to the passport is 6.1 liters, on the highway you can invest in 5.7 liters per 100 km, which makes the crossover one of the most economical in its class of elite vehicles;
- reliability has not yet been tested well, but today we can say that the motor has passed all possible tests and has become one of the most interesting for experts and car buyers;
- the engine is supplied complete with automatic machine, there is four-wheel drive, which even takes a little fuel and dynamics, and this indicates an excellent tuning of the power plant.
The French did their best and created a real warrior. A Koleos car with such a unit is able to please with fuel consumption, quality and travel conditions, reliability and endurance. The car is still very demanding on fuel quality and cannot guarantee optimal driving without normal service. But this common feature all modern diesels that require decent attention.
Hyundai 2.0D 185 horsepower - Korean soldier
Another diesel unit with great endurance and amazing performance is a new Korean development. Just like in the previous version, this unit was being prepared for sale on the European market. Today, this engine is equipped with a new generation Hyundai Tucson. But soon after the release of the car, the persecution began. diesel engines, sales in the target market fell. Interestingly, the unit has the following characteristics:
- very high quality, which allows you to cope with the greatest difficulties on the road, the engine requires only regular maintenance, reliability is proven by reviews;
- in the 2.0D unit, the Koreans offered as much as 185 horsepower, and this is very good indicator paired with a torque of 400 N * m at low engine speeds;
- in the urban cycle, the consumption is 8 liters, on the highway, fuel consumption is reduced to 5.6 liters, efficiency has become another important advantage for most buyers;
- simplicity of design becomes another reliability factor, it should be noted that maintenance requirements are minimal, and the list of materials for maintenance is very extensive;
- a car with such an engine received good dynamics and very successful characteristics, transport has greatly changed its character in comparison with the usual gasoline engine.
Supplied motor with automatic, mechanics for Russian market not provided. The 2.0D engine from Korea has already won its fan base, who are posting accolades online. It is interesting that the reputation of the Korean motor is still clean, not negative opinions of experts and other factors that could make you think about the advisability of buying. Everything is very positive and suggests the thought of purchasing such a car.
Peugeot 1.6 HDi 120 HP - better economy
On a fairly inexpensive Peugeot 408, the manufacturer installs quite suitable and interesting engines. Transport is of the highest quality and simply excellent operating capabilities. Among the engines, there is also one diesel engine, but the range of heavy fuel units may soon expand. Even this one engine pleases with performance and can become one of the main ones on the sales list. And the reasons for this are as follows:
- the engine has only 1.6 liters of volume and 114 horsepower, while the unit drives quite well with 254 N * m of torque and a chic setting from the French;
- naturally, there is a turbocharger and all the accompanying elements of a modern engine of European origin, even if the volume is small, but the power is mediocre;
- consumption in the city will be 6.2 liters per hundred, and on the highway this figure will drop to an incredible 4.3 liters, the savings are tangible, this is what can make you buy this car in the cabin;
- reliability is perhaps a little less than in the case of German engines, but in general the unit does not cause problems in operation, so its quality is very high;
- there are no maintenance problems, the design is simple and understandable for most motorists, there is no doubt that transport will be popular in Russia in the future.
Engine tuning is one of Peugeot's main positives. By the way, Peugeot-Citroen engines have also become the object of attention of crazy environmentalists in Europe, and this promises a reduction in prices for diesel vehicles of these brands in Russia. In general, it’s worth waiting until cars with diesel units cost less in the cabin. petrol versions. It is at this moment that the time will come to go shopping.
By the way, we also offer you to watch a video review of the Peugeot 408 car with a diesel unit under the hood:
Summing up
Much has been said about the technical advantages and disadvantages of diesel power units. In fact, everything has its advantages and bad sides. Gasoline engines do not please with consumption, and on a diesel engine you can save about 3000 liters of fuel only during the warranty period of a car trip. Although the cost of servicing a diesel engine is somewhat higher than with a service for gasoline units, this does not reduce their financial benefits. In addition, modern diesel engines do not cause problems at all in operation. Of course, if you take the experimental Smart diesel, for example, you will definitely feel the difference for the worse.
In general, the most reliable diesel engines have long ceased to be a matter of concern for buyers. In Europe, for several years they bought almost only diesel engines and were very pleased with their quality and reliability. And most of all, it was the economy that inspired me. Nevertheless, it is worth weighing the pros and cons of operating a heavy fuel engine in Russia, where winter temperatures sometimes exceed the freezing threshold of even high-quality diesel fuel. It is up to you to decide whether it is worth experimenting with such cars. And if you are already accustomed to operating a motor with this type of fuel, it's time to upgrade your fleet. What do you think about buying a car with one of the above motors?
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.
Choosing the best diesel engine for Russia, you can count on successful implementation its potential. Experts note that older generations of diesel engines are characterized by a simple design and a margin of safety.
Overview of top units
What models of motors managed to go down in history, having proven themselves from the best side? First of all, the answer refers to German products, which have a well-known quality and are able to please with compliance with 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 injection pump kind.
The above three principles allow the unit to maintain a leading position in terms of mileage, resistance to operational tests. Diesel engines were produced in 1985-2002, which indicates their reliability.
The main advantages were reliability and economy. At the same time, the power correlated with 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 following cars:
- Mercedes in the back of W124, W201, W210;
- SUVs G-class;
- vans T1, Sprinter.
Advice! The list of the best SUV diesel engines includes the Mercedes-Benz OM602, as well as two of its heirs at once - OM612, OM647.
BMW M57
Bavarian BMW engines managed to win a high level of popularity and an ideal reputation. All 6-cylinder units were pleased with reliability, decent power indicators. Cars could accelerate from 201 to 286 horsepower.
The release of motors fell on 199-2008, and it was successfully installed on most Bavarian cars. All famous models BMW was pleased with the presence of the M57 diesel engine. In addition, they can be found on the Range Rover.
The ancestor also turned out to be a real legend - M51. Its release was carried out in 1991-2000. How can you understand Bavarian BMW manufacturer has accumulated very good experience, which is now being actively implemented in the development of diesel engines.
Experts note reliability, because serious breakdowns are rare. Mileage reaches 350-500 thousand kilometers, which is a significant indicator.
Volkswagen diesels
Experienced motorists are trying to find out which are the best Volkswagen diesel engines that have gone down in history and become a real legend. Representatives of one of the most famous automotive corporations in the world have made every effort to still please their admirers with a worthy offer.
Volkswagen employees have carefully studied how fuel economy affects the technical parameters of the engine and the reliability of the ride, the quality of control.
The best is 1.6 TDI engine, 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 acted as follows: pressure in fuel cylinders has been increased while saving fuel. Power characteristics managed to remain 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 show that 3.3 liters of diesel fuel are required for every 100 kilometers. As you might guess, these figures are among the most attractive.
The 1.6 TDI diesel engine has been successfully used in the following vehicles:
- hatchback Golf;
- Tiguan crossover.
Subsidiaries automobile concern, namely - Audi, Skoda, SEAT, actively use this motor. Wondering which diesel engine better audi, you can safely choose the 1.6 TDI version.
Toyota 3S-FE engines
Toyota 3S-FE is one of the most worthy engines, which is reliable and unpretentious. Japanese development managed to gain a high level of popularity due to the following parameters:
- 2 liter volume;
- 4 cylinders;
- 16 valves.
Despite the typical characteristics, they became the basis for the development of the best diesel unit. In addition, the power indicator really pleased: 128-140 horsepower. There were enough options for successful trips on cars.
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 robust design worthy resource.
Diesel engines were installed on the following cars:
- Camry;
- Celice T200;
- carina;
- Corona T170/T190;
- Avensis;
- RAV4;
- Picnic;
- Caldina;
- Altezza.
Interested in whether a Japanese manufacturer offers a good diesel engine for Rav-4, numerous positive responses can be noted. Even car experts note that the power unit is able to adequately endure significant loads, as a result of which serious breakdowns are surprisingly rare. Additional advantages include the convenience of carrying out repair activities and the thoughtfulness of the design, which allows you to quickly eliminate any breakdowns. Good maintenance allows you to focus on a mileage of up to 500,000 kilometers without overhaul.
Despite the fact that many diesel units have gone down in history and gained an ideal reputation, you need to understand how they differ from gasoline engines.
Which is better petrol or diesel engines
When researching the best passenger car diesel engines, it is important to understand what their advantages are. This will help the usual comparison of gasoline and diesel units.
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 ratio useful action, and, consequently, fuel consumption, taking into account the distance covered. In addition, diesel engines provide for successful adjustment of the working mixture, which guarantees the same amount of air to enter all cylinders. At the same time, even maximum power allows you to count on the minimum amount of injected fuel, which leads to decent diesel savings.
The stability of the diesel units is determined by the resistance air filter affecting the air required to fill the cylinders. Correct adjustment injection start pressure allows you to increase the operational life of the motors. At the same time, the need for less adjustment of diesel units is envisaged than that of 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, as their elements are made of durable and tough materials. The use of high-quality fuel with pronounced lubrication characteristics, will allow longer use of the power unit. Experts note that even the best diesel engine in the world requires a responsible approach to its maintenance.
The disadvantages of the units may appear during the operation of the motors. The disadvantages include a large mass, less power compared to gasoline counterparts, noise due to high pressure in the cylinders used, difficult starting the car at sub-zero temperatures. The risk of diesel engine failures appears after the device has traveled 100,000 kilometers. Over time, motor components wear out anyway, so maintenance is as important as understanding deadline operation. Otherwise, the car will not be able to develop optimal power and speed. Most often, the cause of repair measures is increased oil consumption, which can be determined by a change in the color of the smoke emitted exhaust pipe.
Summary
Recently, diesel engines deservedly gaining popularity. Being interested in 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 developing optimal technical parameters in the shortest possible time.
Advantages of diesel engines:
- optimal power;
- resistance to traction;
- fuel economy;
- long service life thanks to a reliable and simple design;
- fuel savings.
There are also disadvantages:
- Difficulty starting the car at low air temperatures;
- the need for regular replacement of engine oil;
- increased requirements for the quality of the 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. The unit that matches the car in its parameters becomes the best choice.
The main component of any car is its engine, which can easily be compared to the human heart. Naturally, the malfunctions of this “organ” will affect the performance of the entire machine, which is why the issue of engine reliability worries car owners so much. What power unit will be the most reliable? Let's try to find out.
1. In-line gasoline "fours"
Inline gasoline engines- These are internal combustion engines with cylinders arranged in a row, the pistons of which rotate one common. Most often, such mechanisms are designated as Ix or Lx, where x is the number of cylinders in a particular engine. I must say that the most common four-cylinder engines can surprise the car owner with a rather long service life, especially since the use of gasoline as fuel has certain advantages, for example, it does not freeze in the cold.
Interesting fact!The first produced internal combustion engines had only one cylinder, so it was necessary to achieve an increase in power by increasing its volume. A little later, the engineers retreated from this method and simply increased the number of cylinders. Thus, from the end of the 19th century, two-cylinder engines began to be used, and from the beginning of the 20th century, four-cylinder units also became widespread.
It's no secret that domestic motorists always preferred gasoline installations than diesel ones, but both types have models that have already become legends. For example, among the usual in-line “fours”, four engines stand out with enviable reliability: Toyota 3S-FE, Mitsubishi 4G63, Honda D-series, Opel 20ne.
The 2-liter 3S-FE power unit was a very common power plant of the 90s. It had four cylinders and six valves, and the power fluctuated in the region of 128-140 hp. It was this type that was supplied with the most popular models. Toyota brands: Camry (1987-1991), Carina (1987-1998), Avensis (1997-2000), RAV4 (1994-2000).
If such an engine is provided with quality service, it can serve faithfully for 500,000 km without major repairs. In addition, a positive feature of the Toyota 3S-FE power plant is also its high maintainability.
Did you know?According to the results of the international competition "Engine of the Year 2016", the best engine was recognized as the Ferrari V8 biturbo, whose power is 670 hp. (installed on the 488 GTB supercar). In addition, the same power unit won in three more categories of the competition: Best Engine in the category from 3.0 to 4.0 liters”, “Best new engine and Best Sports Engine.
The two-liter Mitsubishi 4G63 engine was released in 1982, and its licensed copies continue to be assembled in our time, only in China (previously, specialists from Japan were engaged in this). The first versions of this engine were equipped with only one camshaft, and the cylinders had three valves each (SOHC version). However, five years later, the world saw new variation 4G63, already equipped with two camshafts called DOHC.
It should be noted that throughout the history various modifications of the described power unit were installed not only on cars of the Mitsubishi concern, but also on Korean Kia cars and Hyundai. Currently, the Chinese company Brilliance is engaged in the production of popular engines.
Another representative of reliable gasoline "fours" are Honda D-series engines, which were produced from 1984 to 2005. For 21 years of impeccable work, they managed to get only positive characteristics, and there were up to ten different variations of this unit - from 1.2- to 1.7-liter engines. Power indicators reached 131 hp, and operating speed approached the mark of 7000. It was these engines that were installed on cars Honda Civic, Honda Accord, Honda Stream, Honda HR-V, Integra.
Also, the list of the most successful gasoline "fours" cannot do without another engine - the Opel x20se, which is a prominent representative of the GM Family II. In practice, he repeatedly proved his reliability, especially since in some cases such motors served longer than the machines themselves, on which, in fact, they were installed. The secret of such “durability” lies in a simple design and a rather primitive distributed injection system.
2. Petrol in-line "sixes"
An in-line six-cylinder engine, or simply "six" is another version of an internal combustion engine in which all cylinders are placed in a row (their order of operation is 1-5-3-6-2-4), and the pistons turn one common crankshaft. As in the previous versions, there are also many centenarians among the power units of this type, but to list them all, you will have to spend a lot of time. For this reason, we will recall only the most popular of them.
The BMW M30 was created in 1968 and was produced in various variations until 1994. The volume of this power plant varied between 2.5-3.4 liters, and the power corresponded to 150-220 hp. So long term services this engine due to its classic design: the block is made of cast iron, there is a timing chain drive and a twelve-valve aluminum block head. True, there is also a turbocharged version of the M30 - M102B34 with a capacity of 252 hp.
This type of engine was equipped with machines of three BMW series: fifth, sixth and seventh. Moreover, even in our time there are vehicles with this particular engine. In principle, there is nothing surprising here, because a run of more than 400,000 kilometers without a major overhaul is a rather impressive indicator, although, for example, the same M30 can work for 500,000 kilometers.
The next, no less prominent representatives gasoline inline "sixes" are the Japanese Toyota 1JZ-GE and 2JZ-GE, produced for 17 years (1990-2007). The first option has a volume of 2.5 liters, and the second - 3 liters. In addition, at one time there were supercharged modifications with the indices 1JZ-GTE and 2JZ-GTE.
The engines of this series were equipped with the Supra, Chaser, Soarer, Crown and Mark II models, as well as the GS300 and Lexus Is 300 imported from the USA. It must be said that the resource Japanese motors and the truth is impressive, because there are cars whose engine worked properly up to a million kilometers.
3. V-shaped "eight"
First of all, it should be noted that representatives of the V8 category have never distinguished themselves by too large a working resource, which has its own explanation. The fact is that their design was specially facilitated, while differing in a rather high level of complexity. However, despite this fact, the Bavarian specialists were able to design an engine that successfully overcame the milestone of 500,000 kilometers without disturbing the car owner with frequent malfunctions. Of course, we are talking about the BMW M60, which has a nickel-silicon coating (nikasil) and two rows of chains, which made the cylinders almost indestructible.
There were times when, with a run of 400-500 thousand kilometers, technically, the M60 remained practically new, that is, even the piston rings retained their previous state. It would seem that here it is - an ideal version of the engine, but not everything is so simple. With all its advantages, nikasil coating has one significant disadvantage- the complete absence of sulfur resistance in the fuel. It was this fact that played a cruel joke with the motor.
Engines in America suffered the most, because it is here that fuel with high content sulfur. This fact served as the basis for the use of another type of coating - alusil coating (with the same hardness, it turned out to be more sensitive to impacts than nikasil coating). M60 power plants were produced for six years - from 1992 to 1998, and were installed on BMW cars 5th and 7th series.
4. Diesel engines
In terms of reliability, none gasoline engines will not be able to compare with their diesel counterparts. In past decades, it was hard to imagine sport car with a diesel engine, but those who are used to using the car often still prefer the diesel power plant.
Older models of such units have a fairly simple and durable design. So, for example, the OM602 series of diesel engines is equipped with five cylinders (each of which has two valves) and mechanical Bosch. In the ranking of the most reliable and enduring diesel engines, this particular model should be given first place.
This engine stood on the assembly line for almost two decades - from 1985 to 2002. But it should be noted that these motors were not famous for any superpower, and their advantage was a high level of reliability and efficiency. The predecessors (generation OM617) and successors (OM647 and OM612) of this species were also famous for their high level of endurance.
OM602 million-plus engines can be found on Mercedes cars with W201 (MB190), W124 bodies, on Sprinter vans and T1, G-class SUVs. The mileage of many of these Vehicle exceeds 500,000 km, and some have even reached 2 million km. Regular inspection of attachments and fuel equipment, together with the timely elimination of all their malfunctions, will be able to guarantee a very long operation of the power unit.
Be that as it may, the mileage is different, and much depends on the specific operating conditions. So, the "counter" of the taxi driver big city can wind up a decent mileage in just a few years, which means that this indicator cannot indicate the real life of the engine, because in such a short period of time breakdowns will be quite a rare occurrence, and wear will be minimal.
The life of the engine is not facilitated by the constant presence of “traffic jams” and “pedal to the floor”, not to mention unsuitable temperature conditions. In such situations, it is unlikely that you will have to claim the title of “millionaire engine”.
There are many different ratings of cars according to a variety of criteria: safety, reliability, premium, price, and so on. However, most of the "experts" who make up such ratings completely forget that the key element in any car is the engine. The ability to operate the vehicle itself depends on its efficiency, performance and reliability.
The generation of the 80s and 90s still remembers cars that could travel a million kilometers or more. Today, there is an opinion among motorists that modern manufacturers are not interested in such a durable performance of their products. From a marketing point of view, it is much more convenient for a customer to buy a new car every 3-5 years.
However, not all engines and units of modern cars are so hopeless. There are indeed several ideal options that can last 10 or even more years. Today we will begin to consider the rating of the most reliable automobile motors in different classes. Today you will finally know which engines you can trust.
The voiced rating will help you choose the engine that will be the most productive and durable, parts will not cost too much, and maintenance will be simple. In a word, the ideal power unit. Let's see if it exists.
small class
Class B+ is one of the most popular car classes. They are characterized by simplicity, reliability and lack of newfangled and complex innovations. This means that such features make the power unit really easy to operate and maintain. The number of cars from different manufacturers in this class is simply huge. Here the buyer can choose between domestic or foreign car industry, the choice is very large.
This class of small cars is being intensively developed and improved. Perhaps the most reliable engine in this class is the K7M power unit from the French company Renault.
This motor can be described with just a couple of phrases: 1.6 liters of displacement, 16 valves and stable work. A technologically simple engine is a guarantee of excellent performance and good performance. The timing drive is carried out by a belt, an ignition module, cast iron block- everything is very simple. Such engines are put on the popular Logan and Sandero. These are truly folk cars confidently won a part of the market from domestic cars. The simplicity of the design provides the possibility of long-term and trouble-free operation of this power unit.
The second place in the reliability rating for a small class of cars was received by engines from the VAZ 21116. The standard 1.6-liter, 8-valve engine is simple and reliable. The only thing that can let the owner down here is the build quality and the quality of the wiring. Sometimes this can be a real problem.
The third place of honor is occupied by K4M from Renault. Unlike the motor, which is in the first place, this option is a little more complicated and, accordingly, more expensive. It is somewhat difficult to tolerate increased loads. Logan, Kangoo, Duster, Megane, Fluence and a number of other cars are aggregated with this motor.
Middle class
In this category, the well-known K4M engine can be called the leader. This power unit is installed on Renault cars C-class. These cars are more weighty, therefore, the loads on the engine are completely different. The 1.6-liter unit is somewhat difficult to drive the "heavy" cars of the c-class. Therefore, 1.6 is a separate category from 1.8 and 2-liter versions.
Z18XER is one of the simplest and most conservative engines. The timing drive is carried out by a belt, the injection system is quite simple. The motor has a good margin of safety. The power of this power unit is 140 hp, which is quite enough for a confident bridle in the city or on the highway. Z18XER is installed on such Opel cars Astra J, Zafira and Chevrolet Cruze.
The second place in the ranking is occupied by two-liter G4KD / 4B11 engines, which are installed on Mitsubishi, Hyundai and KIA. This power unit is very reliable and practical. The timing drive is carried out by a chain. This is what made the engine a little more expensive. The power of these power plants from 150 to 165 hp
The engine works great in tandem with automatic transmission or mechanics. Kia Optima, Cee'd, Cerato, Hyundai i30, Sonata, Elantra, ix35, Mitsubishi ASX, Outlander, Lancer - all these cars have this type of engine.
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. Simple design showed high wear resistance even in small engines (for example, 1.1). Outdated 8-valve versions after a timing belt break will not require a major overhaul, which is inevitable for more modern modifications that 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: 8th generation Honda Accord, 3rd generation Honda CR-V, 9th generation Honda Civic.
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 BMW N47 diesel connoisseur will tell you.
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 were replaced with a bypass valve upstream of the bifurcated intake port, with the EGR plugged in 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 Mitsubishi engines very reliable, so it is not easy to choose the most-most difficult. 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. injection system common rail manufactured by Siemens has proven itself from the very beginning. 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 a mechanical control drive throttle valve and an 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 drawbacks are the relatively high fuel consumption (especially in the Legacy 3.0 Spec B equipped with a sports manual with a short-throw gear selector) and minor difficulties when maintenance(for example, to replace spark plugs due to poor accessibility to "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 flaws, small oil leaks through the stuffing box can be noted. crankshaft. 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, almost anyone could have been included in this review. Toyota engines, 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. Simple petrol engine a high degree compression, working on the Atkinson cycle, synchronous 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 Š koda Octavia(1 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. Often mentioned problems with the mass air flow sensor are 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 Skoda Octavia the best TDI considered CMA. 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 weak point of SDI/TDI, especially in the early years of production, is the crankshaft damper pulley.
