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.
