YC6MJ/YC6MK/YC6M Series Engine for marine

FEATURES

  1. The integration of crankshaft, postposition gear chamber and point-line gear-meshing patent technology reduce noise level.
  2. Wet cylinder liner structure facilitates maintenance and repair.
  3. Improved fuel consumption by P7100 fuel pump, P-injector and Honeywell turbocharger achieves high mean effective pressure and power density.
  4. 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.
  5. Yuchai sealing technology in piston ring and valve oil seal reduces the lube oil consumption.
  6. High fuel efficiency and low maintenance cost.
  7. Operator and nature friendly with low noise, rapid start ability and low emissions.
  8. Major overhaul period is more than 12000 hours.
  9. Water-cooled exhaust pipe with the integrated forged steel water liner reduces exhaut temperature and emission.
