Features
Main bearing with support to have high rigidity,low vibration and low noise. BMEP, specific power and other indicators are at the domestic leading level. Internal and external double-circulation water-cooling: internal circulation uses fresh water to cool the engine, and the external circulation uses seawater to cool the fresh water through the sea-fresh water heat exchanger to improve the service life of the engine. Optional water jacket exhaust pipe can be used to reduce the cabin temperature. The unique remote navigation monitoring system can monitor the engine speed,water temperature,oil temperature and pressure data in real time. When the engine parameters exceed the limit, it can automatically alarm and stop the engine. Turbulence mode is now added to ensure no shut-down would happen when the ship encounters wind and waves. Energy-saving and fuel-saving: The properly designed intake oil supply system broadens the operating range and maintains low fuel consumption in the common working conditions and even in the speed range of the ship. Powerful: large power reserve and maximum output torque of 1500N.m, bringing out fast acceleration and high speed suitable for high-speed ships and heavy-duty fishing boats.
