Brand new Yuchai YC6MK series marine diesel engine (163kw to 257Kw)
YC6MK/6MJ
Features & Benefits
The integration of crankshaft, postposition gear chamber and point-line gear-meshing patent technology reduce noise level
Wet cylinder liner structure facilitates maintenance and repair
Improved fuel consumption by P7100 fuel pump, P-injector and Honeywell turbocharger achieves high mean effective pressure and power density
The use of 42CrMo forged steel crankshaft increase fatigue strength and abrasive resistance, and the torque output at front end could be more than 900Nm
Yuchai sealing technology in piston ring and valve oil seal reduces the lube oil consumption
High fuel efficiency and low maintenance cost
Operator and nature friendly with low noise, rapid start ability and low emissions
Major overhaul period is more than 12000 hours
