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
