c) At High Speed Running with a Load
When a load is applied to an engine running at high
speed, the engine speed drops and the centrifugal force
of steel ball (13) becomes less, the fork lever 2 (5) is
pulled forward by the governor spring 1 (2) and 2 (3),
this increases the amount of fuel injected.
The fork lever 2 (5) becomes ineffective in increasing
the fuel injection when it is stopped by the adjusting
bolt (17). After that, when the force of torque spring (18)
becomes greater than the centrifugal force of the steel
balls, fork lever 1 (4) moves forward to increase fuel
injection, causing the engine to run continuously at a
high torque.
d) To stop engine
When the stop lever (19) is moved to the STOP position,
fork lever 1 (4) is moved rearward and the control rack
(14) is moved to the non-injection position, causing
the engine to stop.
