CY4105Q

Good engine with stable performance, and well-used in the operation

Application scale:
	·The engines are mainly applied to 2-4 T light-duty trucks, 6-8m buses and city buses etc.
The main technical performance:
	CY105 series diesel engines are developed on the base of CY102 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.·Overall dimension of model 4105Q  diesel engine is the same with 4102BQ, general-property of parts is very high, usage and maintenance is conventional. Otherwise it is with low oil consumption, low emission and so on.  ·Model 4105Q direct injection vehicle, high speed diesel engine with international advanced level is always keep best state. It features low fuel consumption, high-efficiency and so on. Effectively controlled free accelerate, and reduced emission, making the emission reach regulation of the state. ·Cylinder block of three-dimensional optimization design, high strength alloy steel casting, automatic digital control machinery, so it features good rigidity and light weight.   ·Crankshaft is made of alloy-steel forged, applied advanced technology to treat the surface, so it features good-abrasion resistant and reliability. Optimization dynamic and static balance test, and decrease the loading and moving noise of main bearing.·Powerful, big torque, sufficient power, so it is used to use in the mountain area.·According to the requirement, it can be equipped with air conditioner, steering servo actuator, warm air and so on.  ·Advanced machinery equipment, perfect quality assured system, so it makes quality of the product higher.
