Engine MAN D2156

MAN D2156 – engine of joint Hungarian-German production on diesel fuel with direct injection of a combustible mixture and water cooling.

This engine is widely used on Ikarus 250 buses. RABA-MAN D 2156 are water-cooled and have a combined forced lubrication system. Fuel system operation is provided by a Bosch fuel pump, STA injection regulator and injectors. The air is cleaned by an oil bath air cleaner and a cyclone pre-filter.

Specifications

The RABA-MAN D 2156 engine provides acceptable dynamics (100 km / h), but weak acceleration due to low power. This motor has good maintainability, is quite reliable and simple. Its disadvantages, in addition to insufficient power, include a small resource, which is also a consequence of the low power of the motor and, as a result, constant operation at high speeds. Over the years, transport on such engines becomes more and more noisy due to a burnout of the muffler or improper operation of the engine, and also very smoky.
