Integral Fuel Solenoid
The fuel solenoid is located on the end of the fuel
injection pump.
Operation of the engine is controlled by the
operation of the fuel solenoid and the high speed
(throttle) solenoid. The fuel solenoid consists of a
spring loaded plunger and electro-magnetic coil.
When the engine is Off, spring tension on the
plunger maintains the plunger’s “out” position.
When pushed out, this causes the governor
linkage to move the injection pump rack to the
“Fuel Off” position.
When the fuel solenoid is energized, current is
applied to the coil creating an electro-magnetic
field, which pulls the plunger in. When in the
“pulled-in” position, the plunger releases tension
on the governor linkage. The governor linkage
then moves the fuel injector rack, thus controlling
the fuel flow and placing it in the “Fuel On”
position.
Adjustments made to the throttle (high) speed
solenoid change governor spring tension which in
turn adjust speed settings.
