Weichai 6170/8170 Series 350 ~ 817hp Marine Diesel 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 601kW, rotation speed range is from 1,000 to 1,500rpm
• The engines can widely be used in various shipping
• Structure advantages:
• Gantry structure with the reasonably collocated reinforcing steel bars makes the engine a compact structure with high intensity, high rigidity and low vibration
• 1 cover/cylinder, dual intake pipes and 4 valves/cylinder can supply enough air intake and optimal intake whirlpool
• Easy for maintenance work
• Crankshaft is made of cast iron with high intensity and has been nitrified
• It is collocated with 12 weight counterbalances itself which has greatly lessened the load of the main bearing
• Connecting rod is forged by alloy steel which makes it much more reliable
• Wet cylinder sleeve is cast by alloy of chrome, molybdenum, copper and nickel
• Piston is cooled by injection oil
• So the cylinder has little abrasion and can supply longevity service
• Both P9 high pressure oil pump produced with introduced technology and the imported low inertia injector has super performance and can work with high reliability
• Electric motor and air motor can both be supplied according to the end of the customers
• Engines equipped with both starting device can also be supplied
