(Overloaded Operation)
The amount of the movement of the fork lever
assembly is limited with the fuel limitation bolt (10) and
can not be moved in the direction of the fuel increase.
As overload reduces the centrifugal force of the
governor weight, which is pressing the torque pin (8) into
the floating lever (7), the floating lever pushes the fork
lever 1 (6) in the way to increase the fuel supply with the
help of the torque spring tension.
The fuel supply increases (b) in relation to the degree
of the torque pin motion, thus preventing the engine
speed from dropping.
At the time, the maximum torque limiter (1) prevents
superfluous fuel supply and suppresses the generation
of black smoke.
