Weichai 170 Series Marine Diesel Engine (258-601kW)
Main advantages of diesel engine
★ Strong power:
Supercharger, high pressure oil pump, fuel injector and other performance parts of the optimal configuration, power coverage, sufficient reserve, greater torque, the same at low speed with large torque, better for all kinds of working conditions;
Economy and fuel saving:
Four-valve technology, pulse conversion supercharger, make the combustion more full, low fuel consumption, low fuel consumption economic work area range is larger: at the same time through the optimization of the oil seals, the engine fuel consumption is reduced by 45% than before;
Safe and reliable:
High strength QT800 integral crankshaft, large flow filter before cooling lubrication system and efficient cooling system, less pipe and one cylinder one cover design, ensure the reliability of diesel engine and maintenance convenience.
