weichai WP12 sinotruk diesel marine engine 450hp ship machinery boat engines high speed 2100rpm
Strong power:External characteristic is up to 2100N•m
Environment protect and low noise:Smoke value in range of full load is less than 1.0Rb
WP12C series marine diesel engines based on Landking national WP12 series diesel engine focus on use characteristics and configuration requirements of marine power, adopt design concepts to optimize and design special energy saving and environment protection diesel engine for marine, and is the ideal power for inland shipping, fishing and public boat.
Five special technologies
Reliability Safety High efficiency Low-noise Convenience
Reliability-Special oil pan technology for marine-Flat oil pan
Adopt special flat oil pan for marine with overall stamping design, and arrange the ribs reasonably to improve the strength; no welding line on the surface, formed at one time, prevent the leakage failure, and improve reliability.
Convenient to maintenance
Reduce the overall height, increase the distance to the bottom of the cabin, convenient to replace oil
Safety-Protection technology of preventing burning-Steel low-pressure pipeline+ Water jacket exhaust pipe
Steel low-pressure pipeline
Optimize the layout of fuel pipeline, adopt steel low-pressure pipeline, improve safety and reliability; meanwhile, the appearance is more beautiful, and comply with regulatory requirements of marine.
Water jacket exhaust pipe
Adopt water jacket exhaust pipe cooled by freshwater to reduce the cabin temperature caused by surface radiation effectively, and improve the comfort and safety.
Efficient-Multi-wedge belt transmission technology
High transmission efficiency, stable operation, and reduced the "Turn belt phenomenon" effectively caused by the beating of the original V-belt during transmitting.
Achieved belt automatic tensioning in the process of operating diesel engine and maintenance free according to the auto-tensioner
Low-noise--Flange pump technology--Flange connecting high-pressure pump
Adopt high-pressure pump connect flange to improve the oil pump connection stiffness, and reduced vibration problems caused by connection of coupling to improve reliability and reduce noise.
Convenient--Non-stop filter technology--Replace the filter element in non-stop situation
Replace diesel oil and oil filter element without stopping in the situation of engine operating according to design regulations of marine, and convenient to maintenance.
Reduce occur of failure caused by blocking of filter element during the operating of marine, increase the safety of marine.
1) Simple structure in linear type ,easy in installation and maintation.
2) Adopting advanced world famous brand components in pneumatic parts ,electric parts and operation parts.
3) High pressure double crank to control the die opening and closing.
4) Running in a high automatization and intellectualization,no pollution
