A governor is a device which controls the fuel injection of an engine, depending on fluctuations in load, to keep the
engine speed and output power at a constant level. The governor used for this engine is of mechanical type which
utilizes the balance between the centrifugal force of the governor weight and the tension of the springs. Its control
weight and the tension of the springs. Its control covers the entire speed range from idling to max rpm. The
mechanism consists of the following component part: governor weight, governor lever, governor spring, idle spring,
fuel limiter with built in torque spring, speed control lever, and others.
At Starting
When the speed control lever (5) is moved in the
direction of arrow A, the governor lever 2 (1) is pulled by
the governor spring (6) and the stop lever of the
governor lever 3 (7) turns in the direction of arrow C until
the stop lever comes into contact with the fuel injection
limit pin. The governor lever 1 (2) moves together with
the governor lever 2 in the same direction, but even
when the governor lever 2 has stopped, the governor
lever 1 remains pulled by the idling spring (4) to keep
turning just by the clearance of the lever's slit in the
same direction. This makes the injection pump's control
rack move to the maximum fuel injection rate position,
facilitating the start.
