Valve for motor vehicle engine, has tangentially reduced gas mixture flowing surface for increasing propagation of gas mixture, where gas mixture is heated while flowing through valve

摘要

The valve has a tangentially reduced gas mixture flowing surface for increasing propagation of the gas mixture, where the gas mixture is heated while flowing through the valve. A surface of a needle (1) is reduced for propagation of the gas mixture in a tangential manner or a flowable manner. A drill hole formed in a valve body (2) is enlarged for propagation of the gas mixture in a tangential manner or a flowable manner.
