3) At high speed running with overload
When an overload is applied to the engine running at a
high speed, the centrifugal force of steel ball (13) be-
comes small as the engine speed is dropped, and fork
lever 2 (5) is pulled to the right by the governor spring 1
(2) and 2 (3), increasing fuel injection. Though, fork
lever 2 becomes ineffective in increasing 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 ball, fork lever 1
(4) moves rightward to increase fuel injection, causing
the engine to run continuously at a high torque.
4) To stop engine
When the stop lever (19) is moved to the STOP position,
fork lever 1 (4) is moved leftward and the control rack
(14) is moved to the non-injection position, stopping
the engine.
