At
high
speed running
with
overload
When
an
overload is applied to the engine running at a high speed, the centrifugal force of
ball weights become small
as
the speed
is
reduced, and fork lever 2 is pulled rightward by
governor springs 1 and
2,
increasing fuel injection. Fork lever 2 becomes ineffective
to
increase fuel injection when it is stopped by maximum output limit bolt. After that when the
force
of
spring becomes larger than the centrifugal force of ball weights, fork lever 1 moves
rightward to increase
fuel injection, driving the engine continuously with a high torque.
