Weichai LandKing WP12C Series Marine Diesel Engine
See the large picture

Weichai LandKing WP12C Series Marine Diesel Engine that improved on the basis of the LandKing, is a environment-friendly energy-saving diesel engine with a new design concept.

WP12C series marine diesel engine, is the best supporting energy-saving power with the advantages of compact structure, optimum dynamic and economic performance, high reliability. It is the best power for freshwater transportation, fishery, ships of duty.

Structural features

  • WP12C series of marine diesel engine use the main frame structure of Landking Euro III Diesel Engine with high-pressure common rail, such as the body, the cylinder heads, crankshaft, connecting rod.
  • WP12 high pressure common rail Euro III Diesel Engine which is jointly developed with Austrians AvL company, is a new generation of high-performance energy saving, environmental protection engine. Its
  • Components are in finite element analysts and simulation operation, which makes substantial increase in reliability and service life.
  • WP12C series marine diesel engine use PZ8500-line flange pump, Huoersaite supercharger can be set in the middle or behind the engine. In cold and heat exchangers are seted on the both sides of the diesel engine.
  • Compated to Wd615, WD618 sereis marine diesel engine, Landking Series marine diesel engine are better reliability, power and economy of more obvious advantage.

Performance advantages

  • Low fuel consumption: the lowest fuel comsumption is 192g/kW.h, four?avalve structure and reasonable intake system and combustion system has widened the economic operation range, and ensure the engine work with the best economy.
  • Super power: high-reserve power, high-torque in low speed, acceleration good.
  • Environmental protection, Low noise: framework of the body, low noise gearbox, special sump, which make the engine noise greatly reduced; emission targets advanced, smoke less than 1.0Rb when the engine in full-load.
