1) Before starting

The starting fuel increase spring let the governor

lever move to the "fuel increase" side to raise the

starting performance.

2) After starting

The starting fuel increase spring is compressed by

the thrust force of the governor to stop the starting

fuel increase.

3) Max. speed

Thrust force of the governor increases according to

the rise of revolutions and the fuel is increased until

the reversed angleich spring is completely com-

pressed.

(This is the max. injection position.)

To explain the function more concretely, during the

medium to high load operation, even if the tension

lever contacts the fuel limiter and the rack is at the

max. position, the reversed angleich spring overcomes

the thrust force of the governor since the revolution is

below the max. speed and caused the governor level to

move to the fuel decrease side by the distance of the

control q'ty (

). This is the reversed angleich mecha-

nism, which limits the fuel injection q'ty during

medium to high load operation for preventing "over-

torque" and adverse exhaust color.
