Usage condition of diesel engines are extremely varied，with a wide range of loads and speeds．The governor plays an
important role in the operation of the engine by quickly adjusting the position of the control rack to control the amount of
fuel injected, according to changes of engine speed.
It also automatically controls the engine to prevent engine speed from exceeding the maximum ,and keeps the engine
from stopping.

The governor weight mounted on the end of the fuel injection pump cam shaft rotates around the governor support pin,
driven by the cam shaft, and is forced outwards by the centrifugal force acting on the weight．
The thrust force acting on the cam shaft due to this centrifugal force acts on the lower part of the tension lever through the
sleeve A starting excess fuel spring is mounted on the bottom of the tension lever．
0ne end of the governor spring is hooked to the right upper end of the tension lever, and the other end to the spring lever
