Features:
- Its noise is much lower by adopting the integral crankcase, rear-positioned gear chamber and the patented technology of spot-line meshing;
- The engine is easy for maintenance by means of its approachable design (one cover for each cylinder) and the wet type liner construction;
- The engine is in the lead of products of the same category at home for the indexes, such as the average effective pressure, per liter power, per liter torque etc.;
- 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;
- 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;
- The engine is developed for reliability by AVL technology with strict & accurate mechanical development sequence and so its overhaul period is over 12000 hours;
- 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¡ª200kW gen-sets.
