3.5.3 OPERATION OF GOVERNOR
A. WHEN STOPPED
The fuel is blocked since the solenoid (3) pushes
the speed control rack (4) to the left.
B. WHEN TURNING THE KEY SWITCH ON
When the electromagnet in the stop solenoid oper-
ates and the pin is retracted, the speed rack (4) of
the fuel injection pump is pushed to the right by the
start spring (9) and the idle shaft (10) to supply suf-
ficient fuel to start the engine.
C. WHEN STARTING THE ENGINE AND RUN-
NING THE ENGINE AT LOW IDLE SPEED
When the engine is started, the steel ball (6) pushes
the sleeve (11) to the left as the centrifugal force of
the steel ball increases. Therefore, the governor fork
lever 1 (13) pushes the rack (4) of the pump to the
left to reduce the amount of fuel supplied.
As the rack is stopped by the idle spring (8), it keeps
the balance with the centrifugal force of the steel
ball so that at least the minimum amount of fuel is
delivered for stable engine running at idle speed.
D. ACCELERATION AND DECELERATION
When depressing the accelerator pedal, the gover-
nor spring (1) pulls the fork lever 2 (12) to the right
and then pushes the fork lever 1 (13) to the right.
The fork lever (13) is stopped by the sleeve (11).
When the centrifugal force of the steel ball (6) that
is proportional to the engine speed is balanced with
the tension of the governor spring (1) that is deter-
mined by the driver, a stable speed is maintained.
E. LOAD INCREASE AT HIGH SPEED
When a load is applied to the engine running at a high
speed, the centrifugal force of steel ball (6) decreases
as the engine speed drops. The fork lever 2 (12) is
pulled to the right by the governor spring until it con-
tacts the fuel limit bolt (14). Then, the amount of in-
jected fuel per one stroke of the injector plunger and
the torque increase.
This range (a) is between the max. speed point with no
load and the max. power point of the torque curve.
When the fork lever 2 is blocked by the fuel limit bolt
(14) and does not move any more and the load is
increased, the centrifugal force of steel ball drops fur-
ther and the torque spring (15) compressed between
the fork lever 1 and 2 is loosened. Then, the fork lever 2
moves to the right until the torque spring is free, and
the amount of fuel supplied and the torque increase
simultaneously.
This range (b) is between the max. power and the max.
torque point on the torque curve.

F. WHEN STOPPED
When the key switch is moved to the “OFF” position,
the stop solenoid power is cut off to release the
electromagnet. Therefore, the stop pin comes off by
the return force of the spring and pushes the solenoid
guide (2) and fuel injection pump rack to the stop posi-
tion to stop the engine.
• The fuel limit bolt (14), idle spring (9) and max.
rpm setting bolt are set at factory. Unauthorized
adjustment of such components can negatively
effect the performance of the engine. Therefore,
never adjust them without permission from
DAEDONG. Such action violates the EPA regula-
tion and also can void the warranty.
