Products
Power range：219kW~293.7kW
Applications：public service ships, yachts and speedboats of 7~20m
The reduction soft mesh starter ensures smooth starting; the damping gear enables noise to be shielded; the oil pan of the cast aluminum marine engine reduces vibration noise.
The parts are developed based on the 6L platform and are 94% used universally for 6L series vehicle diesel engines, with good maintainability.
The HPCR system enables strong power and quick response. The four-valve, efficient turbocharged & intercooled technologies, Yuchai's combustion, NVH development + electronically-control fuel injection technologies ensure low comprehensive fuel consumption (with the minimum fuel consumption of 190.15g/kw.h), low operating cost, subdivided purposes, road spectrum collection, fine calibration based on different purposes, guaranteed fuel saving, light dead weight (5% lighter than competing products), and more fuel-efficient.
Developed based on Yuchai's 6L vehicle engine platform with 300,000 6L vehicle engines in the market, the product is mature and stable; the engine block and cylinder head are made of alloy cast iron, with high strength; the 42CrMo forged steel crankshaft enables the product small in size, light in weight and compact in outline structure; the statistical service life of B10 is up to 13,000 hours.
