CY4105 Series Diesel Engine General Situation
CY105 series diesel engines are developed on the base of CY4105 diesel engines by enlarging the cylinder bore, improving design on the aspect of fuel system, power output, with the features such as compact, light weight, powerful, fuel-saving, long service life, good starting performance, low emission and noise etc.
The parts and components have high exchangeability with those of DCD 102 series diesel engines. The engines are mainly applied to 2-4 T light-duty trucks, 6-8m buses and city buses etc. It includes: CY4105 CY4105ZQ
