2.4.2.2. Function of Governor (1) Function of governor Following is a representation of the movement characteristics of the control rack at respective speeds when the speed rise from 0,with the governor control lever at the maximum speed position: A-B : Fuel volume condition during starting. Volume is controlled by excess fuel spring. B-C : The rack moves towards decrease after engine starts and speed increase as the load of the excess fuel spring is overcome by the centrifugal force of the governor weight. C-D : High torque at low speed is developed by increasing fuel injection volume equivalent to the angleich stroke. D-E :
Condition when the thrust force exceeds that of the angleich spring force on the bottom of the tension lever and it gradually pushes the rack to decrease fuel when engine speed increases. E-F : Condition when both right and left ends of the shifter come in contact with the sleeve and the bottom of the tension lever, and the control rack is kept at the normal position by the stopper. max injection volume position on models not equipped with an angleich spring) F : Point when governor starts to take effect. This is the rated output of the engine F’ : Point when governor start to take effect on models with torque spring G : Continuous rating point usually 85 90 injection volume of F point). H :
No load max speed L : Low-idle position 11
