【Abstract】 This paper mainly introduced the 4 valve intake port development progress of CA6DL diesel engine. The main characteristics of helical port and tangent port are analysed, and the influences of these two kinds of intake ports and valve arrangements on the cylinder head structure are investigated. In this paper the developing process of the CA6DL engine port is summarized by using the Pro/E 3D model technology, the developing period is shortened . Finally the designed 4 valve intake port has fully met the engine performance requirements.更多还原
