Brief Introduction
- This series diesel engine is developed by Yuchai adopting the technology of FEV, Germany;
- The cylinder block and head are made of the alloyed cast iron with high degree of the strength; the integral crankshaft & sliding bearing are featured by compact construction, smaller weight and higher reliability; the overhaul period is over 10000 hours;
- The index of the fuel consumption is very low by adopting the A type high pressure fuel pump with a higher injection pressure;
- Consumption of the oil is very low by adopting the Yuchai¡¯s special sealing technology for the piston rings;
- It is an ideal power which can be used as the main machine for small-sized marine and fishery vessels and as the ancillary machine for 20¡ª40kW gen-sets.
