YC6MK Details

Yuchai YC6MK marine engine — OBKA Group

YC6MK Series — Product Description

  • 1. Reliability & durability: Deep thermal-shock, high-temperature and alpine-cold, and crankshaft-fatigue tests during R&D. European development process; overhaul period > 12,000 hours. Integral crankcase, rear gear chamber and advanced point-line meshing gears deliver lower noise and higher comfort.
  • 2. Fuel & cost saving: Independent electronic control enables precise injection, high injection pressure and optimized combustion—stable operation, low combustion noise, strong low-speed torque and quick response. Four-valve design and central injector improve breathing and atomization; proprietary piston-ring and valve-stem-seal tech reduces lube-oil consumption by >50% vs. domestic peers at same power.
  • 3. Safety & comfort: Digital local/remote monitoring and integral cast-iron fresh-water cooling jacket exhaust pipe lower engine-room temperature for safer use.
