Japanese manufacturers have reliable diesel engines. And what is the most reliable diesel engine among all reliable in Japan?
Let's look at the most common modern diesel engines in the Japanese car industry.
What are these diesel engines, what are the strengths and weaknesses of Japanese diesel engines. They now dominate mainly in Europe, but quite often began to appear in Russia.
But, unfortunately, they also have problems when their runs exceed one hundred thousand kilometers, and even some up to one hundred thousand.
The caution in the supply of diesel engines from Japan is due to their capricious attitude to fuel. Their fuel system is rather weak to the use of our diesel fuel.
Another problem is the availability of spare parts. There are practically no non-original spare parts from reliable manufacturers. Chinese ones appear, but their quality leaves much to be desired and does not at all correspond to Japanese quality.
Hence their very high price is dictated, much higher than for German spare parts. There are many factories in Europe that produce spare parts of decent quality and at prices much lower than the original ones.
The most reliable diesel engine from Japan
So what is the most reliable diesel engine from Japan? Let's rank the TOP 5 of the best diesel engines.
5th place
In fifth place, you can safely put the 2.0-liter Subaru engine. Four-cylinder, turbocharged, boxer, 16-valve. Common rail intake system.
It must be said that this is the only boxer diesel engine in the world.
A boxer engine is when mutual pairs of pistons work in a horizontal plane. In this arrangement, careful balancing of the crankshafts is not required.
The weaknesses of this engine are a two-mass flywheel, it failed even up to five thousand kilometers. Crankshaft cracking, until 2009, crankshafts and shaft bearings were destroyed.
This engine is very interesting in its design, with good performance, but the lack of spare parts for such engines nullifies its advantages. Therefore, we give him the fifth place of honor in the Japanese series of diesel engines.
4th place
In fourth place will be the Mazda 2.0 MZR-CD engine. This diesel engine has been produced since 2002 and installed on Mazda 6, Mazda 6, MPV. It was Mazda's first Common Rail engine.
Four cylinders, 16 valves. Two versions - 121 hp and 136 hp, both of which developed a torque of 310 Nm at 2000 rpm.
In 2005, it underwent modernization, with an improved injection system and a new high-pressure fuel pump. Reduced compression ratio and adaptation of the engine with a catalyst for the emission of harmful gases. Power became 143 hp.
Two years later, a version with a 140 hp engine was released, in 2011 this engine disappeared from the line of installed engines for unknown reasons.
This engine calmly nursed 200,000 kilometers, after which it was necessary to change the turbine and the dual-mass flywheel.
When buying, you should carefully study its history, but it is better to remove the pan and look at the oil sump.
3rd place
Also a Mazda engine, Mazda 2.2 MZF-CD. The same engine of increased, but increased volume. Engineers tried to eliminate all the jambs of the old two-liter engine.
In addition to the increased volume, the injection system has been modernized, another turbine has been installed. On this engine, they put piezo injectors, changed the compression ratio and radically changed the particulate filter, which had all the problems of the previous model of the two-liter engine.
But the worldwide fight for the environment, both in Europe and Japan, adds gimoroya to all engines, and a system is installed on this one, with the addition of urea to the diesel fuel mixture.
All this reduces exhaust emissions to Euro5, but as always, in Russia this adds problems to all modern diesel engines without exception. This is simply solved by us, the particulate filter is thrown out and the afterburning valve of the unburned exhaust is turned off.
The rest of the engine is reliable and unpretentious
2nd place
Toyota 2.0/2.2 D-4D engine.
The first two-liter Toyota 2.0 D-4D CD appeared in 2006. Four-cylinder, eight-valve, cast iron block, timing belt, 116 hp The engines came with the "CD" index.
Complaints about this engine were very rare, they all came down only to the injectors and the exhaust gas recirculation system. In 2008, it was discontinued, and a new one was launched instead, with a volume of 2.2 liters.
Toyota 2.0/2.2 D-4D AD
They have already begun to make a chain, there are already 16 valves for four cylinders. The block began to be made of aluminum with cast-iron sleeves. The index of this engine became "AD".
The engine is available in both 2.0 liters and 2.2.
The best reviews about such an engine, and good returns, and low fuel consumption. But there were also complaints, the main one being the oxidation of the aluminum head at the point of contact with the cylinder head gasket, approximately in the period of 150-200 thousand km. run.
Replacing the head gasket does not help, only grinding the cylinder head and block, and this procedure is only possible with the removal of the engine. And such a repair is possible only once, the motor will not withstand the second grinding of the head and block, the depth will be critical with the possibility of meeting the valves with the head. Therefore, if the motor passed 300-400 thousand kilometers, with one grinding, it is only for replacement. Although this is a very decent resource.
Toyota in 2009 solved this problem, with such malfunctions, they even got me under warranty for new engines at their own expense. But the problem is very rare, but it does occur. Mostly for those who are not weak on the strongest version of this 2.2-liter engine model.
Such engines are still produced and installed on various car models: Raf4, Avensis, Corolla, Lexus IS and others.
1 place
Diesel engine Honda 2.2 CDTi. The most reliable small diesel engine. Very productive and very economical diesel engine.
Four-cylinder, 16-valve, variable displacement turbocharged, common rail injection system, sleeved aluminum block.
The injectors are used by Bosch, not capricious and expensive Japanese Denso.
The predecessor of this engine was built back in 2003 with the marking 2.2 i-CTDi. He turned out to be very successful. Trouble-free, dynamic and economical in fuel consumption.
The modern Honda 2.2 CDTi engine in question appeared in 2008.
Of course, typical malfunctions did not pass, but all of them were extremely rare. Exhaust manifold cracks, but they occurred in the first releases, the Japanese reacted and this was not observed in subsequent releases.
Sometimes there were malfunctions of the timing chain tensioner. Also, sometimes the play of the turbine shaft appeared prematurely.
All of these failures arose from excessive constant loads and poor maintenance.
Honda installed this engine on Honda Civic, Accord, CR-V and others.
Of course, this engine has the smallest number of failures and breakdowns in relation to all other engines of Japanese automakers.
We put him five points out of five, assign him the first place of honor and wish you to have a similar one on your car.
Good day to all!
A few words about the service: there is no service in Samara. After the first MOT the next morning I found a puddle of oil under the car! Went to the dealer. After a detailed check and clarification of all the circumstances, they returned the car with an apology, saying that the mechanic had spilled "a little" oil, but forgot to mention it and wipe the engine. At the same time, the oil level on the dipstick is 1 cm higher than normal (on a cold engine and the car stood on a flat area). After turning the brake discs, I picked up the car at night and did not notice abrasions on the front bumper in time, it was too late to present it the next day. In general, if it were not for the "very skillful" hands of our specialists, I think that there would be much more positive from the car, but in the future I am looking for an alternative to the official dealer.
Summing up, I want to say that the car is an amateur. You get used to everything, it's just a matter of time. If the advantages outweigh the disadvantages, there is something to think about and ask yourself: "Are you ready to put up with these disadvantages?"
The Toyota Land Cruiser 200 frame SUV is sold on the Russian market with two powertrain options: a 4.6-liter V8 petrol with a capacity of 309 hp. (439 Nm) and a 4.5-liter V8 turbodiesel with a return of 249 hp. (650 Nm). Both motors during restyling in 2015 are brought into line with the requirements of the Euro-5 standard. The diesel engine traditionally has a wide "shelf" of peak torque, developed in the range of 1600-2600 rpm. Both power plants are combined with a 6-speed automatic transmission.
The all-wheel drive of the car is a full-fledged Full-Time with an asymmetrical center differential (with a forced locking function) and a reduction gear. The suspension consists of a front structure on two levers and a rear axle. To reduce body roll, the KDSS roll suppression system with hydraulically controlled stabilizers is provided.
The atmospheric gasoline G8 installed under the hood of an SUV is famous for its remarkable “appetite”, consuming an average of about 13.9 liters of fuel per 100 kilometers. The fuel consumption of the Toyota Land Cruiser 200 with a diesel engine is significantly less - 10.2 liters when driving in a combined cycle. The installation of a 45-litre tank in addition to the base 93-litre capacity allows the vehicle's range to be increased to an impressive 1,200 km.

Toyota Land Cruiser 200 engines
1VD-FTV 4.5 V8 249 HP
A 4.5-liter diesel engine with the 1VD-FTV index has been installed on the Land Cruiser since 2007. This is one of the first Toyota engines in the V8 configuration. The latest version of the power unit develops 249 hp. and torque 650 Nm. The engine design includes a cast-iron cylinder block, a 32-valve timing belt with two camshafts per cylinder bank (DOHC) and a chain drive, two variable geometry turbines, a Common Rail injection system with electromagnetic injectors, two particulate filters.
1UR-FE 4.6 V8 309 HP
The 1UR-FE gasoline engine was introduced in its homeland in 2009, replacing the 4.7-liter 2UZ-FE unit. It is equipped with two camshafts (DOHC, 32 valves), Dual VVT-i system, ACIS system (change in intake manifold geometry), ETCS-i system (electronic throttle control), EGR.

The SUV is equipped with permanent all-wheel drive with a transfer case, which combines a Torsen center differential with the possibility of hard locking and a lowering row. The front axle is driven by a chain drive. By default, the torque is distributed between the axles in a ratio of 40:60, but this proportion may vary depending on road conditions.
The choice of the operating mode of the all-wheel drive Toyota Land Cruiser 200 is carried out using the selector on the inter-passenger tunnel. Position "H4" corresponds to the standard mode of operation, "L4" - downshift (ratio 2.618). The center differential is locked using a separate button, while the vehicle speed should not exceed 100 km / h.
Elka is a massive car. To set it in motion, a motor with sufficient power is required. For this reason, Mitsubishi L200 engine power is excellent. Depending on the pickup version, power units develop from 128 to 181 hp.
The Elka gasoline unit has been around for several decades. It has been constantly updated and the latest version is used on . This is a reinforced 2.5-liter engine, which is also installed on the Pajero SUV.
The latest version of the unit is capable of developing 178 hp, which is quite enough to compete with peers in the class. Together with the Super Select transmission, the Elka engine delivers excellent results on any road surface.
As for its predecessor, it developed only 136 hp. The motor was used on the 4th generation L200. With such a low-power internal combustion engine, the old Elka could stand out against the background of Hilux and Amarok only at a relatively low cost, because opponents had 156-horsepower installations under the hood. However, a more humane price tag did not help, the demand for Elka began to fall rapidly, and the company's management had to solve a difficult task. The situation improved by strengthening the gasoline engine - this is exactly what the Japanese pickup truck lacked to fight competitors.
diesel engine
The 4-cylinder diesel unit 4N15 is installed on the fifth generation Elka. It is an upgraded version of the 4D56 engine, runs much quieter than its predecessor and has good CO2 emissions. NewengineL200 with a volume of 2.4 liters, configured to return 154 or 181 horses.
This motor is offered with L200 for RF. But, for example, in Thailand, a version with a 2.4-liter gasoline naturally aspirated engine and a 2.5-liter turbodiesel is produced and sold.
Developing 154 hp, it is combined with two available gearboxes: a 6-speed manual and a 5-speed automatic. The same one, which develops 181 hp, is combined only with automatic transmission.
Features of the new L200 diesel engine:
- an aluminum cylinder block is used, due to which it is possible to optimize the parameters;
- the version with modulated geometry works;
- two camshafts operate with the motor - the DOHC system;
- the pressure inside the power system rises to 2 thousand bar;
- direct injection 3-stage;
- valves are electronically controlled;
- compression parameter 15.5:1;
- a timing chain is installed instead of a belt.

Motor 4D56 D-DI 2.5 l
The 2.5 liter diesel engine or 4D56 D-DI is a modernized version of the old 4D56 and 4D56T used on the Pajero, L-300 Delica and L-200 Strada. The modified power plant has different technical characteristics, but the main feature is the absence of liners in the cylinder block, two camshafts and the Common Rail fuel system.
The DOHC power plant has an overhead arrangement of both camshafts. This is an in-line four, with a cylinder head cast from aluminum. The block itself is cast iron. Steel crankshaft, 5-support.
Distinctive features of the upgraded version are:
- the absence of sleeves, which made it possible to reduce the number of elements inside the block;
- more efficient cooling by increasing the diameters of the channels and using a different water jacket with a corrugated surface;
- the use of modified pistons and fingers increased in diameter;
- protection against strong detonation due to the displacement of the axis of the finger;
- providing a better swirl of air flow in the cylinder head;
- use of refractory steel valves.
Concerning the systems working with the engine.
- Injection engine power system - Common Rail. It implies direct fuel injection, the presence of a synchronized injection pump and a fuel manifold that can withstand very high pressure.
- As for the lubrication system, it is endowed with a water-oil heat exchanger. And to cool the pistons, special oil nozzles are used, which have found a place in the cylinder head.
- The powerful diesel 4D56 D-DI would not have done without a closed cooling system with forced refrigerant circulation.
- The air system has a turbocharger and an intercooler.
- The timing system is driven by a belt gear from the crankshaft pulley.
The 4D56 D-DI engine is capable of developing up to 178 hp. However, the capabilities of the power plant are not limited to this. Carrying out chip tuning will further strengthen the engine.
