Cummins diesel generator set governor, the governor is an automatic adjustment device, which automatically increases or decreases the fuel supply of the fuel injection pump according to the change in the load of the diesel generator set, so that the diesel generator set can run at a stable speed. Cummins electronic governor can also choose the size of unevenness according to the needs of the unit. When performing non-differential speed regulation, the electronic control system will eliminate the difference between the set speed and the actual speed caused by the load change, so that the unit maintains the original set speed. According to the needs of the unit, the unevenness potentiometer can also be adjusted to make the speed control system obtain a satisfactory static speed control.
