Engines from JAPAN Reviews
Engines ACURA
Product specification cars Acura, as a rule, do not differ from that of the models the company Honda. Even the names of the models are the same. Most of the models produced directly in North America (TL series and CL), and some models - RL and NSX because of low demand are imported from Japan. Issue only American Acura model in 1999 amounted to 101.3 thousand. Units. It is worth noting that the best Acura is a Japanese engine i-DTEC (turbo engine), it was put into production in 2009. Thanks to i-DTEC reduced harmful emissions, has great power, less fuel, is environmentally friendly, does not create a lot of noise, provides excellent handling characteristics. Drive the car with the engine i-DTEC is a pleasure.
Engines NISSAN
Engines of this company are the most reliable and unpretentious (foresee that many will disagree with me), but see for yourself:
1) Only Nissan manufactures engines with a gear and chain timing mechanism, which, as you know better than the rubber timing belts.
2) In case of overheating of the engine in diesel engines Nissan, very rarely occurs warping or cracking of the cylinder head.
3) Many of the Nissan gasoline engines allow long enough to ride at the Low-Octane gasoline, but do not abuse it.
I can give you some more examples, why the Japanese Nissan engines are not inferior in quality to the other best Japanese models. Since engines VQ, which are models Cedric, Maxima / Cefiro and many other models, about 7 years old are considered the best in the world in their "classmates".
Engines TOYOTA
Engines of this company well to repair and very reliable (though, as they say, the motor engine - strife). The Toyota engine is quite rare to find these "bells and whistles" as the balancing shafts (as opposed to Mitsubishi, which loves them very much); Variable valve timing (although Toyota has become wider still to implement the system VVTi) and other things that affect the reliability. At Toyota cars are well-organized engine compartment, so serve these cars quite easily.
Among the Japanese Toyota engine can be seen as a very good and reliable engines and machines is clearly bad. The best engines are in-line 6-cylinder series, and JZ 1G. Repairing engines Series A (except 4A-GE, with 5 valves per cylinder) is very easy. Repair of other engines Toyota does not give you much trouble. Failure of the engines of Toyota, can be attributed only diesels 2C-T, 2L-T (E), and gasoline Series VZ. The latter very quickly wear counterbalanced crankshaft journals.
Engines MITSUBISHI
Perhaps the most problematic and difficult to repair is the Japanese engines. Designers engines Mitsubishi, apparently did not try to look for simple and reliable solutions. Using plastic carburetors, balancing shafts, systems, direct fuel injection, V-shaped arrangement of cylinders, of course, does not increase the maintainability and reliability of the engines.
For example, many do not understand how in-line four-cylinder engine, standing on the model Galant, manages to work very gently, but then everything is simple, this is achieved by "artificial" way, through the use of balancing shafts. When the engine is no problem, the shafts are working properly, all right, but just happens to open the drive to the rollers (which often occurs on supported units), the engine that was not originally designed to work without them, may eventually get into a very serious repair. Particularly problematic are 4D56 and 4D55 diesel engines with turbocharging, they often burst the cylinder head, as the material from which they are made, can not withstand low temperatures our harsh Russian winters.
On the reliability of heads greatly affect the low temperatures and for this reason, because of the high temperature stress cracks in the heads. The higher the temperature difference on both sides of the wall, the higher the thermal stresses. Now imagine - outside minus 20, you rush to work, crank your engine, because of the lack of time, decide not to warm up to operating temperature (by the way, many people are doing it, because they have a very long wait) and start moving. From the combustion chamber, an intensive heating of the head, even though the coolant temperature and the entire head is even lower labor. In this situation, the thermal stresses are too high, moreover, there are mechanical stresses on the gas pressure. In any case, in one or several times the cracks do not appear immediately.
But gradually begin to appear microcracks, which can then develop into such that through them, to the coolant gas will break. It is worth noting that in a warm engine can be high thermal stresses when the engine will run for a long time under high load, and even at full supply of fuel.
But on the naturally aspirated diesel engines difficult to detect cracks in the heads, because they usually do not happen there, and all this thanks to the lower thermal stress, because less fuel is burned, respectively, the temperature of gas in the cylinder downward. Headache mechanics - EFI - Diesel 4M40, to be more precise, it is diesel with electronically controlled TVND, it can often be seen on the model Pajero.
Let's just say, the Japanese Mitsubishi engines are designed for a very timely and competent service. And if you decide to buy a car Mitsubishi, it is better to take it to the engine, "simple", say with 4G15, occurring on the model Lancer.
Engines HONDA
This automaker produces very high quality engines, with a minimum of defects. If you normally operate the engine Honda (ie will produce timely maintenance, and do not fill it poor-quality oil and gasoline), then bring you unpleasant surprises, he will not. However hondovskie engines have their own characteristics, which can not be ignored:
1) Many (but not all!) Engines this company has a high degree of boost, so often happens when Japan brought some Honda Integra (the tachometer red zone she starts with 8000 rev / min) and its engine had It needs major repairs, as the resource is already developed.
2) If repairs often have great difficulties because of such widespread at the Honda "bells and whistles", as the two carburetor with electronically controlled on one engine, VTEC, etc. Honda engines have even the crankshaft rotates in the opposite direction, in contrast to other Japanese engines.
3) this engine certainly necessary quality oil and fuel, and, this also applies to the high performance engine.
But most of the problems, as we have said, comes from the "clever" and uprated engines Honda, if, as on your car is "calm" the engine (for example, F23A or C35A), then you have nothing to fear.
Engines MAZDA
Engines Japanese company "Mazda" is not the most reliable, but not the most problematic. In Mazda's not much love to experiment with engines (excluding rotor units). Due to the fact that Mazda engines are no different innovations that have a positive impact on their maintainability and reliability. According to these indicators, they are only slightly inferior engines Toyota.
Engine SUBARU
Many Subaru engine has Opposite arrangement that provides high rigidity and strength of the cylinder. It is worth noting that the repair Subaru moved quite difficult.
Older engines Series EA82, which were issued before 1989, has always been known for its reliability. From 1989 to the present time in the cars Subaru began to put the latest series engines EJ (EJ15, EJ18, EJ20, EJ25, EJ30). We can not say that they are very reliable, in general, pretty good. The only thing they differ, so it is moderate force, the system of direct fuel injection and variable valve timing lack itp It should be noted that the car brand Subaru and Honda has not put diesel engines. Subaru engine demanding on the quality of fuel and oil, so the quality they are about on a par with the engines Toyota.
Engines SUZUKI
Because Suzuki engines do not deliver to its owner much trouble, can not be said about them is bad. True to say anything about the little motors with a working volume of 660 cm3 (by the way, Suzuki produces many cars with such engines), I can not. In popular models Vitara Escudo and set inline 4-cylinder G16A, working volume of 1.6 liters., Fairly easy to repair as well as reliable, but the newer V-shaped 6-cylinder J20A with a working volume of 2.0 l. and H25A with a volume of 2.5 liters. more capricious than the 4-cylinder G16A.
Engines DAIHATSU
It is worth noting that these vehicles too little information about them, respectively, too little. In them I have not noticed any specific defects. Historically, designers have not attracted Daihatsu different "twists" such as variable valve timing.
Engines ISUZU
This Japanese automaker has long ceased to produce its own models of cars. To date, Isuzu is famous for its SUVs and trucks, which are often put diesel engines. It must be said that the Japanese Isuzu diesel engines are always known for their ruggedness and reliability (though diesel 4JX1, which is put on the model and Trooper Bighorn is still less reliable than nissanTD27). If we talk about gasoline engines Isuzu, there is nothing wrong, I have not heard about them, the more that they are relatively simple design.
