Diesel engine is in operation, appear load (throttle) add do not go up.This situation is generally caused by the following factors:

1) the pressurized fuel limit of the governor is in effect, causing the throttle (load) cannot be added.Pressure limit characteristic line should be adjusted.Generally by the governor company technical personnel for adjustment.Adjustment can only be made if the governor + points are familiar to the technician.

2) adjustment of installation position of governor output rocker arm and oil adjusting rod system:

If the rocker arm is not installed correctly, then the governor output shaft is in the maximum position, but the rocker arm control oil pump rack is not in the maximum throttle position.At this time, the installation Angle of the rocker arm should be adjusted to meet the requirements.

3) during the refueling process of the governor, it is restricted by the maximum oil] limit screw of the oil adjusting rod system.

Cause governor refueling, in fact, the elastic rod by compression, and fuel pump rack is not moving, so that the throttle can not be added.Therefore, the rod system and the maximum throttle limit screw should be readjusted.

4) in the oil adjusting rod system, there is loosening or the connecting pin is loosening, so that the rack of the fuel injection pump will not move when the governor is refueling.The looseness shall be eliminated to ensure the tracking performance of the refueling/reducing action.

5) the nozzle is damaged, resulting in bad atomization, which causes the load cannot be added and the exhaust temperature is on the high side.The nozzle needs to be replaced to return the atomization to normal.

6) air exists in the fuel oil circuit, which reduces the amount of oil actually injected into the cylinder and causes the load not to be added.The air in the oil pipeline should be eliminated to ensure the oil supply.

7) the control signal is not in place, so that the throttle (load) can not be added.Adjust the control signal to meet the requirements.
