4.电控高压共轨系统的功能在共轨喷油系统中,喷油压力的建立与喷油量互不相关,喷油压力不取决于柴油机的转速和喷油量。在高压燃油存储器(即“共轨”)中,始终充满着高压燃油,而喷油量、喷油正时和喷油压力由电控单元(ECU)根据其中存储的特性曲线和传感器采集的柴油机运转工况信息算出,然后控制每缸喷油器的高速电磁阀开闭来实现。
4. The function of electronically controlled high-pressure common rail system Common rail injection system, the establishment of injection pressure and fuel injection are irrelevant, injection pressure does not depend on the speed and fuel injection diesel engine. High-pressure fuel storage (ie, “common rail”) is always filled with high-pressure fuel, and fuel injection quantity, fuel injection timing and injection pressure are collected by the ECU based on the characteristic curves stored therein and the sensors Of diesel operating conditions information is calculated, and then control each cylinder injector high-speed solenoid valve to open and close to achieve.
