M33 series marine diesel engine
- Torque reserve 20%-30%
- Minimum fuel consumption 190g/kW.h
- Overhaul period 20000h
- Emissions meet IMO II/China I/China II
Product advantages
Safe and reliable
- Cast iron body, grid structure, high-strength one-piece forged steel crankshaft
- Utilizing Weichai's global excellent supplier system, the quality of parts is reliable
- All seawater pipes are made of cast copper or stainless steel, and pure copper seawater pumps are more resistant to corrosion
- Cooling and lubrication systems are equipped with emergency ports
Powerful
- Wide power coverage, more than 20% torque reserve
- Diesel engines are divided into high and low speed versions. The low speed version of the diesel engine has a higher torque value at medium and low speeds, and the high speed version of the diesel engine has a higher torque value at medium and high speeds, which is better adapted to different ship types.
Economical and fuel-efficient
