The governor serves to keep engine speed constant by automatically adjusting the amount of fuel supplied to
the engine according to changes in the load. The engine employs an all-speed governor which controls
centrifugal force of the steel ball(13) weight, produced by rotation of the fuel camshaft (9), and tension of the
governor spring 1 (2) and 2 (3) are balanced.
b. Operation of Governor
a) At Start
The steel ball(13) has no centrifugal force. As the
fork lever 1 (4) is pulled by the start spring(1), the
control rack(14) moves to the maximum injection
position. At start, the sufficient injection of the fuel
enables easy starting.
