CY4102BZLQ

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. The main technical parameters of CY4105   Model  CY4105Q   Type  vertical, in-line, water-cooled, four strokes, NA/T   No. of cylinder-bore×stroke  4—105×118   Displacement  4.087   Type of combustion chamber  direct injection, square combustion chamber   Compression ratio  17.5:1   Rated power/speed (KW/r/min)  74/3000   Max torque/speed(N·m/r/min)  265/2000   Full load min.fuel onsumption  230   Max. idling speed  <3300   Idling steady speed  ≤700   Oil & fuel consumption percent ratio %  ≤0.3   Firing order  1-3-4-2   Emission standard  EuroΙ   Net weight  330/340   Overall dimension(L×W×H)mm  790×660×750   Application  The engines are mainly applied to 2-4 T light-duty trucks, 6-8m buses and city buses etc.

Application scale:
	·The series diesel engine widely applied 2-3 tons cargo truck, all kinds of city buses, luxurious traveling bus and bus.
The main technical performance:
	Model CY4102BZLQ turbocharged diesel engine is developed on the base of CY4102BZQ diesel engine, adopting air to air inter-cooling technology, improving design on intake and exhaust system, fuel supply system, combustion system cooling system as well as lubrication system,with the emission standard of Euro II.The engine bench test, reliability test, vehicle road performance test and the customer operation have proved this version engine has a reasonable design and advanced performance index. The critical parts such as cylinder block, crankshaft,piston etc.have adopted new structure, new manufacturing process,which greatly increase the strength and rigidity and have higher operation reliability ·Crankshaft material:     42CrMo, with nitriding surface treatment.   ·Injection pump: PWS pump·Injector: Long body closed P type,holes6×Φ0.24.
