The 4D56 engine was developed in 1986 by the Japanese automobile company Mitsubishi. After that, for 10 years, Japanese engineers were finalizing it. The main task for the designers was to increase the power and service life, to ensure normal maintainability.
4D56 is designed according to the standard layout, the cylinder heads are made of aluminum and the block is made of cast iron. It was the use of such alloys that made it possible to achieve the smallest mass and provide excellent thermal stability. In 2001, the production of 4D56 with a Common Rail fuel system began. New pistons were used, which reduced the Compression ratio to 17. All this allowed an increase in power by 10 hp and torque by 7 Nm.

Frequent problems
- a lot of problems are caused by numerous leaks from gaskets or oil seals;
- injector nozzles quickly fail and the motor starts to smoke;
- at low mileage may make noise and require replacement of the crankshaft pulley;
- the balancer shaft belt is about 50,000 km long;
- fragile fuel return pipes – overtightening can lead to early damage;
- The aluminum cylinder head often cracks on over 100,000 km.
