摘　　要：定压预胀比对狄塞尔循环的最高温度有直接影响,而共轨系统也直接影响着预胀比及循环最高温度,从而影响循环热效率及平均有效压力等技术指标。以潍柴国Ⅴ柴油机为例,主要对照装配共轨系统的柴油机萨巴德循环与未装配共轨系统的狄塞尔循环的最高温度以及其他技术指标。Constant pressure pre expansion ratio has directly influence on the highest temperature of Diesel cycle. The common rail injec-tion system also has directly influence on the highest temperature and pre expansion ratio, thereby, it also affects the technical property inde-xes, such as thermal efficiency and average valid pressure. Taking National V diesel from Weichai company as an instance, the highest temper-ature and other technical property indexes of Sabah cycle with a common rail injection system and Diesel cycle without a common rail injectionsystem were compared.

关 键 词：共轨系统 狄塞尔循环 萨巴德循环
