Yuchai YC6MJ/YC6MK/YC6M Series Marine Engines
· 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 ad 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
· Water-cooled exhaust pipe with the integrated forged steel water liner reduces exhaut temperature and emission
