        Product Features

      1. Safe and reliable: It uses a frame-type main bearing structure, and boasts high stiffness of the engine block, and low vibration and noise; it is cooled by internal and external circulating water cooling means, of which the internal circulating water part uses fresh water to cool the diesel engine, and the external circulating water part uses seawater to cool the fresh water through the seawater/fresh water heat exchanger, so as to extend the service life of the diesel engine. And, the engine can be equipped with an optional water jacket exhaust pipe to reduce the temperature in the engine compartment.
      2. Strong power: It boasts large power reserve, rapid acceleration and high speed.It is suitable for high speed ships and heavy duty fishing boats.
      3. Fuel economy: The well-designed intake and oil supply system widens the operating range of the diesel engine and are able to maintain low fuel consumption in both normal operating conditions and speed ranges.
      4. Strong practicality: The unique Yuanhangbao monitoring system is able to monitor the speed, water temperature, oil temperature and pressure and other data of the diesel engine in a real time manner, and in case that the diesel engine parameters exceed the limit, an automatic alarm is triggered and the engine is shut down; the wind/wave mode is added to ensure that the ship is not shut down at critical moment.
