Product Description

The integration of crankshaft, postposition gear chamber and point-line gear-meshing patent technology reduce noise level.
Wet cylinder liner structure facilitates maintenance and repair
Improved fuel consumption by P7100 fuel pump, P-injector and Honeywell turbocharger achieves high mean effective pressure and power density.
The use of 42CrMo forged steel crankshaft increase fatigue strength and abrasive resistance, and the torque output at front end could be more than 900Nm.
Sealing technology in piston ring and valve oil seal reduces the lube oil consumption.
High fuel efficiency and low maintenance cost.
Operator and nature friendly with low noise, rapid start adility and low emissions
Major overhaul period is more than 16000hours

1.Its noise is much lower by adopting the integral crankcase, rear-positioned gear chamber and the patented technology of pot-line meshing;
2.The engine is easy for maintenance by means of its approachable design (ove cover for each cylinder) and the wet type liner construction;
3.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 torgue etc;
4.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 velve oil seals and adopting the Yuchai's special technology for the piston rings and oil sealing technology for the valve;
5.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 torgue of 900N.m or above.
6.The engine is developed for reliability by Euro AVL technology with strict & accurate mechanical development sequence and so its overhaul periods is over 12000 hours;
7.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;
8.It is an ideal power which can be used as the main machine for speedboats, cargo ships, fishery vessels.
