YC6MJ/YC6MK/YC6M Series diesel engine


Type characteristic
The overall crankcase, rear gear housing and dot line meshing patented technology, lower than the same product noise;
Wet cylinder liner is easy to maintain and repair
High power density and average effective pressure are achieved by using P7100 oil pump, low inertia small bore P injector, and Honeywell high efficiency supercharger;
The front end of the crankshaft can output torque greater than 900N.m, the torque reserve is large, and the maximum torque of the external characteristics is 2150N.m;
Seal technique for piston ring, lubricating oil consumption more than 50% low power;
High fuel efficiency and low maintenance cost;
Lower noise, faster start-up, lower emissions;
European technology, reliability development using depth and generalized mechanical procedures, the overhaul period is greater than 12000 hours
Integral cast iron water jacket exhaust pipe with lower engine room temperature
