Abstract:
1. A governor for controlling the fuel pump of a supercharged compression ignition internal combustion engine, comprising a pneumatic actuator having a member movable between predetermined end positions and having a first pressure side and a second pressure side, the first pressure side being fluidly connectable to a point between the engine's supercharger outlet and cylinders, the second pressure side being at a lower pressure than the first pressure side, the actuator producing a force via a mechanical outlet dependent upon the pressure acting across the member, the governor further including mechanical connecting means for connecting the mechanical outlet of the actuator to the control means of the engine's fuel pump such that an increase in the pressure on the first pressure side relative to the second pressure side acts so as to reduce the quantity of fuel delivered by the fuel pump to the engine.
