柴油机PT燃油系统的基本原理是根据燃油泵输出压力和喷油器进油时间控制循环供油量,以满足柴油机不同工况的需要。供油计量时间即喷油器计量室与油道接通的时间,而计量室量孔的关闭取决于柱塞的位置。喷油器喷油升程指的是喷油器柱塞由最高点压至最底部所经过的距离,它不
The basic principle of the diesel engine PT fuel system is to control the circulating fuel supply according to the output pressure of the fuel pump and the fuel injection time to meet the needs of different operating conditions of the diesel engine. The fuel metering time is the time when the fuel injector metering chamber is connected to the gallery, and the metering chamber volume shutoff depends on the plunger position. Injector injection stroke refers to the injector plunger from the highest point of pressure to the bottom of the distance, it does not
