Features:

l Its noise is much lower by adopting the integral crankcase, rear-positioned gear chamber and the patented technology of spot-line meshing;

l The engine is easy for maintenance by means of its approachable design (one cover for each cylinder) and the wet type liner construction;

l The engine is in the lead of products of the same CAT-parts-partsegory at home for the indexes, such as the average effective pressure, per liter power, per liter torque etc.;

l The index of the fuel consumption is much lower by adopting the P7000 type top-class fuel injection pump, P type low-inertia & small-aperture injector and the new type Honeywell high-efficiency turbocharger; consumption of the oil is much lower by increasing the number of valve oil seals and adopting the Yuchai’s special sealing technology for the piston rings and oil sealing technology for the valve;

l The crankshaft is greatly improved itself in fatigue strength and wear resistance by adopting the pressure-forged 42CrMo steel blank and high-frequency quenching journals & fillets, and so its front end is able to outlet a torque of 900N.m or above;

l The engine is developed for reliability by AVL technology with strict & accurate mechanical development sequence and so its overhaul period is over 12000 hours;

l The engine is installed with digital & intellectual machine-side & remote monitoring instruments to facilitate operation, monitoring & automatic protection of the diesel engine and effectively ensure safe operation of the engine;

It is an ideal power which can be used as the main machine for speedboats, cargo ships, fishery vessels and as the ancillary machine for 150—200kW gen-sets.
