YC6MK Integrated the advanced technology of Germany America and Japan. YC6MK is the new generation engine especially developed to meet the requirements of vessels. it is ideal for powering various kinds of vessels. lt is used as the ideal power for 150-250kw auxiliary genset.
The integration of crankshaft, postposition gear chamber and point-line gear-meshing patent technology reduce noise level.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.
