Engine Stop Solenoid (IDI Engines)

Figure 15
When the key is turned to the ON position, the
engine stop solenoid (Figure 15, (1)) is energized
and allows the fuel injection pump to deliver fuel to
the engine, allowing the engine to be started. When
the key is turned to the OFF position, the engine
stop solenoid is de-energized and shuts off the fuel
supply from the fuel injection pump to the engine,
causing the engine to stop.
Speed Control of Electronically
Controlled Engines
3CE1
The electronically controlled engines have no
governor lever. For these engines, the position
signal of the throttle lever or accelerator pedal of
the driven machine is converted into an electric
signal by the accelerator sensor Figure 16, which is
then delivered to the rack actuator of the
Eco-governor Figure 18 through the E-ECU
Figure 17, allowing the engine speed to be
controlled.
