weichai marine WP12C marine engine for yachats

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-pssure common rail, such as the body, the cylinder heads, crankshaft, connecting rod.

WP12 high pssure 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.

WP12C series boat engineadvantages
Low fuel consumption: the lowest fuel comsumption is 192g/kW.h, fourvalve 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.

The cylinder block adopts cast iron and lattice structure to enhance the strength of cylinder block; arrange observation window beside the engine body to replace connecting rod and connecting rod bearing more conveniently. The cylinder block adopts single cylinder head and reasonable design of cooling water chamber to cool the cylinder head more completely.
1. Lubrication system is designed by European top design team.
2. flow oil pump could support higher engine oil pssure (Rate point reaches 0.62MPa)
3. There is hand pss engine oil pump installed on engine body, which could p-lubricate the engine to reduce starting resistance
4. Bypass engine oil centrifugal filter improves quality of lubricating oil.
