Everyone knows that once, in the distant 80s and 90s, there were "millionaire" motors that served faithfully for hundreds of thousands of kilometers. So, in fact, it is - we made their rating not so long ago. But there are worthy successors of the cause of "millionaires" even today.
For some reason, it is believed that modern cars are disposable. Ride three years, sold and went for a new one. But this is at least an exaggeration and a generalization. Indeed, there is failed engines, but this is only part of the market. People own cars for 5-7 or even 10 years and, scary to say, buy them second-hand! So, reliable motors exist. Question: how to find them?
What car and with what engine to buy, so that it not only does not break down during the warranty period, but also does not fall under recall campaigns, does not require expensive consumables and special service equipment. He ran happily ever after, albeit more slowly, consuming a little more fuel than more progressive brothers.
Renault 1.6 16v K4M
Different classes of cars have their own leaders, and, of course, more complex and expensive cars are not well suited for harsh operating conditions, but they also have their leaders and laggards in terms of the required amount of maintenance and the likelihood of failure.
small class
Let's start with class B +, since this size is one of the most common in Russia. The segment is developing rapidly, and there are a variety of cars in it: both our Kalina-Grants and foreign cars for every taste and budget. Almost all machines are extremely practical and are not burdened with special innovations. But this is only in Russia; abroad, such cars are often equipped with more advanced engines. Fortunately, there are few "imported" cars, most of the cars in this segment have long taken root on Russian soil and are produced here, or supplied in special Russian configurations.
The undisputed leader is the K7M engine from Renault. The recipe for reliability is simple: a displacement of 1.6 liters and only eight valves, no complications. Timing belt drive, no hydraulic lifters, a simple cast-iron block, a simple ignition module, no "newfangled" things at all. Such motors are installed on the "folk" Logan and Sandero and do not cause much trouble. There is simply nothing to break, and the workmanship is excellent.
The second and third places, perhaps, should be given to the VAZ-21116 and Renault K4M engines. The first engine is also 1.6 and eight-valve, simple and reliable. But sometimes build quality, wiring quality fails, and cars with manual transmission are not the most reliable, because the box is not designed for increased torque.
Renault's sixteen-valve K4M engine is just a little more complicated and a little more expensive. Not so easy to carry high loads. But they install it not only on Logan, but also on Duster, Megane, Kangoo, Fluence and other cars.
Middle class
There is already one of the leaders in reliability in the C-class - this is the mentioned K4M from Renault. But cars are somewhat heavier, cars with automatic transmission are more common, which means that the power requirements are slightly higher. 1.6 engines will obviously have a smaller resource than engines with a displacement of 1.8 and 2 liters, which means that it is worth highlighting 1.6 engines in a separate group for those who do not need to drive fast.
Probably the simplest, cheapest resource engine for cars in the C-class can be called the very venerable Z18XER. The design is the most conservative, except that phase shifters and an adjustable thermostat are installed. Timing belt drive, simple injection system and a good margin of safety. The power of 140 forces is enough for comfortable movement of such difficult machines as Opel Astra J and Chevrolet Cruse, as well as the Opel Zafira minivan.
The second place in terms of reliability can be given to a series of engines from Hyundai / Kia / Mitsubushi G4KD / 4B11. These two-liter engines are the heirs of the famous Mitsubishi 4G63, including in terms of reliability. It was not without a system for adjusting the timing phases, and in its drive - quite reliable chain. Simple power system and good quality assembly, but chain drive The timing is more complicated and more expensive, and the motor itself is noticeably more technologically advanced, so only second place. The power of the motors, however, is noticeably higher, all 150-165 hp. This is more than enough for any C-class car with any load, on the highway and in the city, with automatic transmission and with "mechanics". Such engines were installed on a huge number of cars, here and Hyundai i30, Kia Cerato, Ceed, Mitsubishi Lancer and other cars and crossovers of a higher class: Mitsubishi ASX, Outlander, Hyundai Sonata, Elantra, ix35 and Kia Optima.
The Renault-Nissan MR20DE / M4R engine may well claim third place. This two-liter gasoline engine has been produced for quite a long time, since 2005, and in design it also goes back to " glorious ancestors"F-series from the 80s. The key to success is precisely in the conservatism of the design and a moderate degree of forcing. Compared to the leaders, it has a less reliable cylinder head, sometimes the chain still stretches, but still it allows you to exchange all three hundred thousand kilometers with careful operation, and the price of spare parts does not go off scale.
Junior business class
In the D + segment, two-liter engines from among the C-class reliability leaders are also popular, and here they look good, because the mass of cars does not differ so much. But complex and "prestigious" high-power motors are more popular.
Motor 2AR-FE with a power of 165-180 hp and a working volume of 2.5 liters is installed on one of the bestsellers in the D + segment, on Toyota Camry, and without a doubt is the most common and reliable motor in its class. They are installed on RAV4 crossovers, and on Alphard minivans. The motor is quite simple, but the key to success is the quality of performance and frequent maintenance of Toyota cars.
The second place is deservedly received by the G4KE / 4B12 engines from Hyundai / Kia / Mitsubishi. These engines have a working volume of 2.4 liters and a power of 176-180 hp. installed on Kia Optima, Hyundai Sonata, many others passenger models and a galaxy Mitsubishi crossovers Outlander/Peugeot 4008/Citroen C-Crosser. The design is close to the G4KD / 4B11 motors, and in the same way they are the heirs of reliable Mitsubishi motors. Design without any special frills in the form of direct injection, timing chain drive plus phase shifters. A good margin of power and resource, not too expensive parts- that's the key to success.
But there will be no third place. Turbo engines on European cars are noticeably more difficult to operate and potentially more vulnerable. Relatively reliable turbodiesels still require more High Quality service. And the third place goes to fairly simple units, for example, the already mentioned Z18XER on Opel Insignia or Duratec Ti-VCT on Ford Mondeo, and if you have enough power and you drive calmly, then they will also be the most inexpensive to operate.
Senior business class
Prestigious E-class sedans are not low cost cars, and the engines in this class are complex and powerful. And often they cannot boast of special reliability. But even among them there are leaders and units with high reliability.
Again, Toyota is in the lead, or rather Lexus, but you know that the company is essentially one? Motors 3.5 of the 2GR-FE and 2GR-FSE series are installed on Lexus models ES and GS and luxury Lexus SUVs RX. Despite the high power and low weight, this is a very successful gasoline engine, in the version without direct injection it is considered one of the most hassle-free in its class.
Second place is deservedly occupied by Volvo with its inline "six" B6304T2 with a volume of 3 liters. The first turbo engine in our rating turns out to be even simpler and cheaper than diesel engines in operation. Largely due to the venerable age of the design with a good margin of safety and relatively low prices for service.
Unfortunately, the naturally aspirated 3.2 is no longer available, it is undoubtedly even more reliable and could claim first place in this category. The secret of success lies in the modular design of the engines. This family has been produced since 1990 to the present day in four, five and six cylinder versions. Continuous improvement of the design and rich experience in the operation of motors has a good effect on the reliability and cost of operation.
For Infiniti, which is in third place, in this class, the Q70 model plays with the legendary “six” of the VQVQ37VHR series with a volume of 3.7 liters and a power of 330 hp. The key to success in this case, too, is the quality of execution, the glorious and long history of the series of motors and prevalence. Such motors were installed on the sports Nissan 370Z, and on the QX50 and QX70 SUVs, and on the smaller Q50 sedan.
Don't expect a rating here. An F-class car is never cheap to operate, in modern car of this level, all the achievements of technology are collected recent years, all the most complex and expensive equipment. They have, of course, their leaders and their outsiders, especially since German executive sedans are produced with very reliable diesel engines, while Korean and Japanese premium brands focus on the reliability of gasoline engines and warranty. But it is difficult to make a choice between them, and it does not make sense, in this class there are other rules of the game.
We bring to your attention the 10 best Japanese auto companies, you will find out what engines they produce. It is clear that a car is chosen not only by what engine it has, but still, this factor should not be "discarded". You will learn the consumer properties of the best Japanese auto engines, such as resource, reliability, efficiency, ease of operation, and repair. 10 best Japanese engines, read in this publication.
After reading this article, many will say: “Yes, my 4D56 is the best engine, has never been repaired, and it only consumes 5 l / 100 km.” Therefore, I will immediately make a reservation that everything that is written in this article is based on statistics. And if your engine hasn't broken down yet, you're lucky. I would like that this article read by the inhabitants of the western and central regions of the Russian Federation, tk. it will help them make up for the lack of “communication” with Japanese cars.
Toyota
The engines of this company are perfectly repairable and very reliable (although, as they say, the engine is different for the engine). In Toyota engines, it is quite rare to find such “bells and whistles” as balancing shafts (unlike Mitsubishi, which loves them very much); valve timing configuration system (although Toyota has increasingly begun to implement the VVTi system) and other things that affect reliability. At cars Toyota has a well-organized engine compartment, so servicing such cars is quite simple.
Among Japanese Toyota engines, you can meet both very reliable and excellent engines, as well as obviously bad units. by the most the best engines are in-line 6-cylinder JZ and 1G series. Repairing A-series engines (not counting the 4A-GE, which has 5 valves per cylinder) is not at all difficult. Repair of other Toyota engines will not give you any special trouble. Toyota's bad engines include only 2C-T, 2L-T (E), and petrol series VZ. In the latter, the crankshaft bearing necks wear out very rapidly.
The engines of this company are the most reliable and undemanding (I expect that many will disagree with me), but see for yourself:
1) Only Nissan produces engines with gear and chain timing drives, which, as you know, are better than rubber timing belts.
2) When the engine overheats in Nissan diesel engines, warping or cracking of the cylinder head quite rarely occurs.
3) Many gasoline engines Nissan allow you to drive on 76-m gasoline for quite a long time, but you should not abuse it.
I can give a few more examples why Japanese Nissan engines are not inferior in quality to other best ones. Japanese models. So the VQ engines, which are on the Cedric, Maxima / Cefiro and many other models, have been considered the best in the world among their own “classmates” for about 7 years.
Diesel engines of the TD series installed on the Safari / Patrol, Terrano / Pasfinder, Caravan / Urvan models were originally developed for boats. You probably do not understand, but marine engines have always been very reliable, unlike cars. On the engines of the TD series there is a gear drive of the gas distribution mechanism. It is necessary to see that the timing gear drive can often be found on the Toyota 3V diesel engine. In the main, there are no problems with this engine, but if they do, it is exclusively in the fuel system.
The only shortcomings of Nissan engines are that they are more difficult to maintain and repair, compared to Toyota engines. This is due to the fact that under the hood nissan cars everything is very tightly packed.
I note that the best and most reliable Nissan engines are SR18/20, RB20/25/26, GA13/15/16, TD23/25/27/42.
Basically, Nissan had no problematic engines, not counting the CA18 / 20 (due to the dual-circuit ignition system) and VG20 / 30 (fast wear of the crankshaft bearing journals).
Mitsubishi
Perhaps the most problematic and difficult to repair are Japanese engines. Mitsubishi engine designers apparently did not try to find ordinary and reliable solutions. The introduction of plastic carburetors, balance shafts, specific fuel injection systems, V arrangement cylinders, of course, does not increase the maintainability and reliability of engines. For example, it is not clear to many how in-line four-cylinder engines standing on Galant models, it is possible to work very gently, but everything is simple here, this is achieved by an “artificial” rim, thanks to the use of balancing shafts. When there are no problems with the engine, the shafts work normally, everything is fine, but as the drive to the shafts breaks (which often happens on supported units), the engine, which at first was not designed to work without them, can eventually get into a very serious repair. Particularly problematic are the turbocharged 4D56 and 4D55 diesels, whose cylinder heads often explode because the material from which they were made cannot withstand the low temperatures of our formidable Russian winters.
The reliability of the heads is very much influenced low temperatures and it is for this reason that cracks appear in the heads due to high thermal stresses. The higher the temperature difference on both sides of the wall, the higher the temperature stresses. Now imagine - on the other side of the window it is minus 20, you are in a hurry to work, start your own engine, due to lack of time decide not to warm it up to operating temperature(by the way, a lot of people do this, because they have to wait a very long time) and start moving. From the side of the combustion chamber, a saturated heating of the head occurs, despite the fact that the temperature of the cooling water and the entire head is even lower than the working one. In this situation, the temperature stresses are very high, in addition, there are mechanical stresses from gas pressure. In any case, cracks will not appear immediately in one or a couple of times. But evenly microcracks will begin to appear, which can then grow into such that gases will break through into the coolant through them. It is worth seeing that even on a warmed-up engine there can be the highest thermal stresses if the engine will work for a long time under the highest load, and even with a full supply of fuel.
But on naturally aspirated diesels, it is difficult to find cracks in the heads, since they usually do not exist there, and all this is due to lower temperature stresses, because. less fuel is burned, respectively, the temperature of the gases in the cylinder is less. Pain in the head of auto mechanics - EFI - diesel 4M40, to be more precise, it is a diesel engine with electronically controlled high pressure fuel pump, it can often be found on the Pajero model.
Let's put it this way, Japanese Mitsubishi engines are designed for a very timely and qualified service. And if you decide to buy a Mitsubishi car for yourself, then take it better with a “more ordinary” engine, for example, with the 4G15 found on the Lancer model.
This auto concern produces very high quality engines, with the least number of flaws. If you operate the Honda engine normally (in other words, you will create maintenance on time and will not fill it with bad oil and gasoline), then it will not give you nasty surprises. But Honda engines also have their own characteristics, which cannot be ignored:
1) Many (but not all!) engines of this company have the highest degree forcing, therefore it often happens when some Honda Integra is brought from the Land of the Rising Sun (on the tachometer, the reddish zone starts at 8000 rpm) and its engine already needs a complete overhaul, because. it has already developed its own resource.
2) When repairing, huge difficulties often arise due to such common Honda “bells and whistles” as: two carburetors with electric control for one engine, VTEC, etc. Honda engines even crankshaft spinning in reverse side, unlike other Japanese engines.
3) These engines certainly need high-quality oil and fuel, and this also applies to highly accelerated engines.
But most of the troubles, as we have already said, come from the “wound” and forced Honda engines, but if your car has a “measured” engine (for example, F23A or C35A), then you have nothing to fear.
Mazda
Engines Japanese company Mazda are not the most reliable, and not the most problematic. At Mazda, they don’t really like to experiment with engines (not counting rotary units). Due to the fact that Mazda engines lack various innovations, this has a positive effect on their maintainability and reliability. According to these indicators, they are only slightly inferior to Toyota engines.
Subaru
Many Subaru engines have a boxer assembly that provides higher rigidity and strength of the cylinder block. It is worth seeing that Subaru was rather difficult to repair. Old engines, the EA82 series, which were produced before 1989, have always been famous for their reliability. From 1989 to the present time, new engines of the EJ series (EJ15, EJ18, EJ20, EJ25, EJ30) began to be installed on Subaru cars. This is not to say that they are very reliable, in general, they are quite good. The only thing they differ in is the moderate degree of forcing, specific fuel injection systems, also the absence of variable valve timing, etc. It is worth seeing that diesels are not installed on Subaru and Honda cars. Subaru engines are demanding on the quality of fuel and oil, therefore, in terms of quality, they are approximately on a par with Toyota engines.
Due to the fact that Suzuki engines do not deliver special troubles to their owner, one cannot say bad things about them. True, I can’t say anything about small motors with a displacement of 660 cm3 (by the way, Suzuki produces many cars with such engines). The popular Escudo and Vitara models are equipped with in-line 4-cylinder G16A, the displacement is 1.6 liters, they are quite ordinary in repair, they are also reliable, but the newer V-shaped 6-cylinder J20A with a displacement of 2.0 l. and H25A with a volume of 2.5 liters. more capricious than the 4-cylinder G16A.
Daihatsu
It is worth seeing that there are very few of these cars, so there is not much information on them either. I didn't see any flaws in them. It so happened that Daihatsu designers are not fond of various "bells and whistles" such as variable valve timing.
This Japanese automaker has long ceased to produce its own models of cars. At the moment, Isuzu is known for its SUVs and trucks, which are often equipped with diesel engines. It must be said that Japanese Isuzu diesel engines are always famous for their unpretentiousness and reliability (although the 4JX1 diesel engine, which is installed on the Bighorn and Trooper models, is still the least reliable than the Nissan TD27). If we talk about Isuzu gasoline engines, then I have not heard anything disgusting about them, especially since they are relatively ordinary in design.
Specifications Acura cars, usually do not differ from the corresponding characteristics of the models Honda. Even the model names are the same. Most of the models are made specifically in North America(TL and CL series) and individual models- RL and NSX are imported from the Land of the Rising Sun due to low demand. The release of only American Acura models in 1999 amounted to 101.3 thousand units. It is worth seeing that Acura's best Japanese engine is the i-DTEC (turbocharged engine), launched in 2009. Thanks to i-DTEC, the amount of harmful exhaust gases, has great power, consumes less fuel, is environmentally friendly, does not create a lot of noise, provides good running properties. Driving a car with an i-DTEC engine is a pleasure.
And in conclusion, I would like to add that in our top 10, the best and most reliable Japanese engine is the one that is correctly exploited. I hope that this article will help you resolve many disputes when choosing a car.
Diesel engines for cars are different, and it's not just the volume and number of cylinders, so let's try to briefly review modern market and find out which of the motors are the most reliable.
To whom did the ratings give leadership?
Associations with the word "diesel" among a resident of Russia are always unambiguous: the smell of diesel fuel from passenger bus, black cinder from a passing truck, vintage jeans and a watch from the brand of the same name. Nevertheless, for most Europeans, the word derived from the name of a German inventor is synonymous with a reliable, inexpensive and powerful “heart” of a car. In our country, its popularity is not so high, apparently due to weather conditions and knowledge that diesel fuel thickens in the cold.
Reliability ratings, and especially for cars, are a thankless task. How many opinions, so many lists, in which the compiler simply expresses his view on a particular subject. That is why we want to draw your attention to the fact that the rating below does not claim to become an indisputable truth, but is just an attempt to systematize the data, knowledge and (partially) personal point of view of the compiler.
In search of an answer to the question of which diesel engine occupies a leading position in the configuration of passenger cars, you can see that some ratings call the best products from Mercedes and BMW concerns. However, the situation in the world of the automotive industry today is somewhat different, let's try to figure it out.
As shown by the rankings of major world car showrooms, the days when passenger car diesel engines were reduced copies of units installed on heavy trucks are a thing of the past. Particularly successful in the production of such motors known to all Volkswagen concern, who developed the 1.9 TDI engine. To date, it ranks first and is considered the most balanced in terms of dynamics and power.
Thanks to the latest engineering solutions, in particular, an updated turbine and an increase in pressure in the combustion chambers, managed not only to achieve unique environmental performance, but also to reduce. Moreover, the power remained at the same level (90–120 hp). The newest cars in the Passat series are now equipped with the highest performance engine (BlueMotion package). Fuel consumption is 3.3 liters per 100 km.
Diesel winners of the car market
The second place is occupied by a modification of the engine with three turbines, owned by the German company BMW. The first time this unit was introduced a few years ago. It has 6 cylinders and, having a volume of 3.0 liters, is capable of developing a power of 381 hp. With. Complete with these engines latest cars 5 and 7 series, as well as heavy crossovers with X5 and X6 indices. Its modification is provided with convertibles having serial number 6. True, it has two turbines, due to which the power is reduced to 313 hp. With.
Not so long ago, cars were presented to potential buyers, whose engines have four turbines, and with a torque of 800 Nm, the power will be within 390–406 hp. With.
A car with a four-turbine engine
The third place in our rating was taken by the American company of industrial diesel engines Cummins, which released a super-powered engine on order. famous company Dodge. In fairness, it should be noted that overseas manufacturers did not pay too much attention to diesel engines, preferring to develop gasoline ones. However, the recent increasing demand for cars with units that consume diesel fuel has forced them to pay attention to the production of diesel engines.
The model proved to be quite powerful (240–275 hp), but in an attempt to occupy the “diesel” niche in the market, the Americans were cunning and passed off as their development by the Italian concern Fiat. The Maserati Ghibli was equipped with a model of such an engine, but due to the crisis, production was given to US industrialists.
This engine was recognized not only as the most environmentally friendly, but also the most innovative: in its production, metals used in the space industry and plasma fuel filters were used. The fact that the engine took only third place is a "merit" of a narrow focus. It is installed only on sports cars and Dodge Ram pickups. In terms of efficiency, it can give odds to its competitors: the consumption is only 8.5 liters per 100 kilometers.
Who is not far behind the top three?
The Koreans, who broke into the global automotive market 20 years ago, not only managed to take their rightful place on it, but also “move” the Japanese giants in the ranking. Having come a long way "from electric kettles to mining trucks”, they also do not want to miss their benefits, which promises an increased demand for cars equipped with diesel engines.
As always, Asian manufacturers acted very cunningly: not wanting to overhaul production and compete with Europeans and Americans in the power of units, they managed to create a 1.7-liter engine that can produce 110–136 hp. With. Do not rush to wrinkle your nose contemptuously! With such rather modest (compared to products from other manufacturers) data, Hyundai's diesel engine has such an incredible torque that it is not inferior in dynamics gasoline units having a capacity of 150-170 liters. With.
I must say that the Hyundai i40 car supplied to the European market is equipped with such a unit. In Korea, diesel engines were also somehow not found. wide application(or the wave of “fashion” has not yet reached there), and therefore they are still being installed only on export cars. Recently, the same unit appeared on a crossover with the ix35 index, and now it is equipped with such popular cars like Grandeur and Sonata. Fuel consumption, however, is more than that of competitors, but the Koreans do not seek to surprise anyone. Their mission is to deliver reliable workhorses capable of average fuel consumption, in this case 5.5 liters per 100 km.
"Squeezing out" enough power from cars and having won its cell in the market, Japanese concern Toyota now makes no sense to prove something to anyone. The concept that manufacturers have thrown all their efforts into is ecology and economy while maintaining sufficient power. And they succeeded. Creating an engine for their compact car named Urban Cruiser, they thought that the residents of megacities would not only be convenient to move around the city, but also that a “calculator” would not turn on in their heads, calculating fuel costs.
One of the smallest diesel units to date is a 1.4 liter engine with a power of only 90 hp. With. This is the fifth place in our ranking. Such parameters, however, do not interfere with the creation of torque, allowing you to easily "pull" all-wheel drive vehicle. The consumption of diesel fuel, depending on the mode of travel, ranges from 4 to 6 liters per 100 km.
So which one is the most reliable?
Such a question is a bit naive, since this parameter depends on many factors, including driving style. But if you choose the best from the above list, then the reliability will be given to the Americans Cummins with a Dodge engine.
And it's not about power or fuel consumption per 100 km. Most likely, the materials used in production play a role. The cylinder block is made of high carbon cast iron, capable of withstanding not only high pressure, but also significant temperature conditions. And its pistons are made of a special aluminum alloy, which is used in the details of spacecraft. This means that they are able to withstand long work under extreme conditions, and sharp rise load when changing speed.
The engine is also equipped fuel system injection common rail, which, despite a rather capricious attitude to the quality of diesel fuel, not only significantly saves its consumption, but also plays a decisive role in reducing engine noise. It is with these engines that both sports cars and cars are equipped. off-road. That is, precisely those instances of the automotive industry, the operation of which takes place in extreme conditions, requiring from the motor not only unsurpassed power, but also impeccable reliability.
If we talk about the rating of cars that are suitable for Russian roads, it is best to pay attention to the samples Japanese made. Optionally, it will be Toyota (which, by the way, not a single Russian motorist has any complaints about the engine).
For our vast expanses, Mazda, Honda, Nissan or the newly revived Datsun will do just fine. The Subaru performed quite well.
The fact is that European cars equipped with a diesel engine are very sensitive to our diesel fuel, the cleaning quality of which leaves much to be desired. As numerous reviews of car owners show, Japanese cars are less prone to malfunctions when using. diesel fuel, thanks to numerous cleaning devices, electronic devices and built-in preheaters that do not allow diesel fuel to solidify at low temperatures.
Car owners dream of a super reliable engine, the best in the world, and which will not break down. There are such legends and not just one. Such legends give rise to controversy: Japanese engines against German and European ones in general, and those against American ones.
There are people who are ready to certify the reliability of an engine that has run a million or more kilometers. They will not be embarrassed by the unknown history of the engine, although they themselves have been using it for a couple of years. Folk tales do not lie - there are motors that can be considered the best in the world in terms of reliability. Not without the help of mechanics, a list of the best motors was created.
It includes the great masterpieces of designers of eminent manufacturers. Not all the best engines in the world are represented in it. The list contains truly reliable and popular units. Such motors were installed in iconic car models of past years.
The best diesel engines of all time
Diesel engines are traditionally considered reliable and among them there are few of the best in the world. Indeed, in old motors, designers used simple but reliable schemes. And they didn’t put diesels on sports cars, so scorchers don’t drive diesel cars.
Opens the list of the best diesel engines world Mercedes-Benz OM602. Its features:
- 5 cylinders;
- 2 valves per cylinder;
- mechanical injection pump from Bosch;
- release from 1985 to 2002;
- power from 90 to 130 liters. With.
On some machines that are still in service, it was covered under 2 million km. It does German diesel is the best engine in the world. These engines were installed on minibuses Sprinter, T1, W124 Geliki.
For your information! The only flaw best diesel Mercedes - injection pump. It crashes sometimes. Attachments also require proper care.
The next representative of the best diesel engines in the world is also from Germany - BMW M57. The lively temper of the Bavarian changed the image of diesel engines, its characteristics:
- in-line arrangement of 6 cylinders;
- power from 200 to 286 hp;
- in production from 1998 to 2008.
The ancestor of the best Bavarian diesel engine in the world is the M51, which was produced from 1991 to 2000. The M57 was installed on the BMW 330D, which in the 46th body ceased to be a taxi driver's car.
The most reliable gasoline engines
In the vastness of our fatherland gasoline engines more popular than diesels, since gasoline is easier to start in cold weather. Another advantage of gasoline is simple design. Among the best gasoline engines in the world there are even small 4-cylinder ones.
Opens the Toyota 3S-FE list. This unpretentious hard worker has following characteristics:
- volume 2 l;
- 4 cylinders;
- 16 valves;
- production from 1986 to 2000;
- power up to 140 l. With.
Installed this best benzie new engine in the world for many Toyota cars, including crossovers. This Japanese unit is famous for its unpretentiousness. A long period of being on the conveyor indicates the success of the motor. Its design is typical of the 90s.
For your information! The best gasoline engine in the world from Toyota used a camshaft belt drive and distributed fuel injection.
The engine from Toyota easily tolerates heavy loads and does not quality service. But it is easy to repair it due to its simple design. If the power plant is properly monitored, then it will cover over 500 thousand km. without overhaul, while there will be a reserve for the future. Minor Issues not specific to this engine.
But there are not so many reliable V-shaped 8-cylinder engines. Such engines have a complex layout and design, which is as light as possible. Therefore, it is difficult for them to get into the best engines in the world in terms of reliability. Americans don't count. The engines that do not annoy their owners include the BMW M60. Good strength helped to achieve a chain in 2 rows and nikasil coating. The design was worked out by the company's engineers for a long time and was somewhat strangled. Due to the special coating, the cylinders wear out little.
Attention! Nickel-silicon, as Nikasil is called, is afraid of fuels with a high sulfur content. Therefore, the motor did not take root in the American market.
Later, the Bavarians began to produce the M62 engine, which turned out to be more difficult, and as a result, less reliable.
It should be repeated that not all of the best engines in the world are included in the list. This is especially true for V-shaped engines. Each car owner has his own preferences for motors and everyone has the right to present their own opinion. But the presented motors have written their name in the history of the automotive industry and are not yet going to retire. It's no joke, but it is unlikely that they departed at least 30% of the time allotted to them, although almost all of them have been discontinued. That is why they are still writing history.
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 species that supplied 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 overhaul. In addition, a positive feature of the power Toyota installations 3S-FE is also a 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".
two liter Mitsubishi engine 4G63 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 motor were supplied 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, which was called DOHC.
It should be noted that in its history, various modifications of the described power unit were installed not only on Mitsubishi cars, but also on Korean Kia cars and Hyundai. Currently, the production of popular engines is engaged in Chinese company Brilliance.
Another representative of reliable gasoline "fours" are Honda engines D-series, 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 Honda cars 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. Such a long service life 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 in-line "sixes" are 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 enough high level difficulties. 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 owner of the car. 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 a high sulfur content is used. 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, no gasoline engines can compare with their diesel counterparts. In past decades, it was difficult to imagine a sports car with a diesel engine, but those who are used to driving a car often still prefer a 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 and T1 vans, and 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, but the mileage will be 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 real resource engine, because in such a short period of time breakdowns will be quite rare, 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”.
