Yuchai 4F overhead camshaft high-speed diesel engine developed successfully

Recently, the first 4F overhead camshaft of the electronically controlled Guotai 4 high-speed diesel engine developed on the basis of the 4F platform was successfully ignited in the laboratory of Yuchai Engineering Research Institute, signifying Yuchai’s new breakthrough in the light vehicle diesel engine sector. The industry’s leading technology advantage. It is understood that the YC4F overhead camshaft diesel engine application DCR high pressure common rail system development, the design of the use of overhead camshaft technology, so that the engine's calibration speed of 3800r/min or more, the power can be increased to 90kW or more. In addition, a set of cooling EGR system with ejector function has been carefully designed to improve the EGR rate and uniformity, and particle capture technology has been adopted in post-processing to ensure that the engine has reached the national 4 emission standard. These advanced technologies have been developed and applied. It is at the leading level in the current domestic similar light diesel engine.
