Weichai 6170 Engine

Weichai X6170ZC series and 8170ZC series marine diesel engines are 6-cylinder and 8-cylinder diesel engines that improved on the basis of the original 170Z series diesel engine. By selecting more advanced turbocharger, high-pressure injection pump, injector, intake pipe and combustion chamber, the engines possess advantages of wide power range, low fuel consumption, low emission and rapid starting.

Meanwhile, the cylinder block, cylinder liner, exhaust pipe and oil sump are all been improved, and the engines are more reliable, more advanced, with operation and maintenance more convenient. The power range is from 258 to 735kW, rotation speed range is from 1,000 to 1,500rpm. The engines can widely be used in various shipping.
