Stop solenoid
The stop solenoid operates for normal shutdown of
engine operation.
The stop solenoid moves the rack of fuel injection
pump to cut the fuel, and consequently stops the
engine.
Two types of stop solenoids are available.
RUN OFF (ETS: Energized To Stop) type
Not energized while the engine is running. Energized
by a stop signal to stop the engine.
RUN ON (ETR: Energized To Run) type
Energized while the engine is running, and de-ener-
gized to stop the engine.
