العربية Our diesel engines are suitable for light duty trucks, medium duty trucks, heavy-duty trucks and 6-9m buses as well as engineering machines, etc.
Diesel engine CY4100 series is further divided into two subcategories which are CY4100Q series natural aspirated engines in Euro I emission standard and CY4100ZLQ series turbocharged and intercooled vehicle engines in Euro II emission standard. Both subcategories are inline, 4-stroke, 4-cylinder diesel engines which are ideal power equipment for 1.5-3ton trucks, 6m buses, 4-wheel agricultural vehicles, minibuses, and diesel generating sets, as well as many other types economic, energy saving vehicles.
CY4100Q Series
Our CY4100Q series 4 cylinder diesel engines are designed with reduced cylinder bore size on the basis of CY4102BQ series vehicle engines. The parts and components of CY4100Q series are almost interchangeable with that of our CY4102BQ series diesel vehicle engines, and both series engines are easy and convenient for repair and maintenance. CY4100Q series diesel engines feature high economy efficiency, high power index, easy start, and low emission, etc.
CY4100ZLQ Series
CY4100ZLQ series turbocharged engines are developed on the basis of our CY4100 series diesel engines, by taking advantage of turbocharged intercooling technology and making improvements on engine's intake and exhaust system, fuel supply system, combustion system, cooling system and lubrication system, as well.
