康明斯柴油发动机PT燃油系统与高压燃油系统的区别?康明斯柴油发动机PT燃油系统?
1.PT系统输出的燃油压力**大不超过300PSI（21kg/cm2）?2.所有的喷油器都共用一根供油管?
3.即使有些空气进入燃油系统也不会使发动机“失速”?
4.PT油泵不需要正时调?
5.有80%左右的燃油用于冷却喷油器后回到油箱，喷油器得到很好的冷却?
6.喷射压力范围高达10000PSI--20000PSI??(703--1406kg/cm2?),这样保证良好的雾化，可使燃油有效地燃烧?7.油管连接处少量漏油对整个发动机输出功率无影响?
8.发动机的停车是切断燃油的流动?
9.通用性好，相同的基础泵和喷油器作一些调整就可以实用于不同型号的发动机在大范围内的功率和转速的变化?康明斯柴油发动机高压燃油系统?
1.高压油泵输出的油压高达????2500--3000PSI?(176--225kg/cm2)?2.每一喷油器需从油泵中单独引出供油管?3.当空气进入燃油系统时发动机马上“失速”?4.高压油泵需要正时调整?
5.只有极少量的回油，喷油器无法很好的冷却?
6.喷射压力范围为：2500--3000PSI(176--?225?kg/cm2)?
