Description
MD485 diesel engines are new type, direct-injection engines made on the basis of MD485 diesel engines. They have the following features: (1) Through simulation test for engine body, small curve surface is added to big curve surface of each cylinder skirt and thickness of bottom plate is increased, which have greatly raised rigidity of engine body and reduced vibration, noises, so performance and liability of motor have been raised. (2) In line with suggestions of AVL CO., spiral intake passage has been redesigned and direct-injection combustion chamber been adopted, which have reduced the lowest oil consumption ratio as displacement and starting performances.
