Features:
¡ñThis series diesel engine is the product developed by Yuchai merging the technologies of FEV, Germany
¡ñThe cylinder block and head are made of the alloyed cast iron with high degree of the strength; the integral crankshaft & sliding bearing is featured by compact construction, smaller weight and higher reliability; the overhaul period is over 12000 hours;
¡ñThe index of the fuel consumption is much lower by adopting the turbo-charging & inter-cooling technology for the intake system and A type high pressure fuel injection pump & P type injector;
¡ñConsumption of the oil much lower by adopting the Yuchai¡¯s special sealing technology for the piston rings;
¡ñThe 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;
¡ñIt is an ideal power which can be used as the main machine for speedboats, cargo ships & fishery vessels and as the ancillary machine for 90kW gen-sets.
