2) AD086TI
Governor system for fuel injection pump consists of “Integral Actuator” and “Speed Control Unit”.
(1) Integral Actuator
•
Functions of Actuator’s component
1. Emergency stop lever
It is emergency stop lever operated by manual at emergency.
2. Upper control chamber
The cover for controlling the inside is installed.
3. Electro control chamber
Operating lever is started by the electric signal generated in it.
4. Adjusting screw
As it is a part of controlling the max. fuel amount if the length which comes outside is long
the torque decreases or if the length is short the torque increases.
5. Fuel stop plate
It is the plate which prevents fuel from increasing by stopping the proceeding of adjusting
screw.
6. Operating lever
It is a connecting lever for operating the fuel rack.
7. Fuel lever
It is connected with link lever, controls fuel amount of the fuel injection pump.
