【 摘 要 】

Pressure constant pre-expansion ratio has directly influenced on the highest temperature of Diesel cycle. The common rail injection system also has directly influenced on the highest temperature and pre-expansion ratio, thereby it also affects the technical indices, such as thermal efficiency and average valid pressure. Taking National VI emission standard diesel from Weicai Company as an instance, the highest temperature and other technical indices of Sabah cycle with a common rail injection system and Diesel cycle without a common rail injection system were compared.
