Abstract: In a mechanical fuel pump control device for a diesel engine, air at intake manifold pressure is fed to an actuator that is used to control the amount of fuel being injected into the engine cylinders. The mechanism is designed such that an increase in air pressure reduces fuelling and a decrease in air pressure increases fuelling. By this means the engine's (rotational) speed is held substantially constant at a predetermined value, the variation in (rotational) speed with increasing load (speed droop) being controllable within the design by altering the effective rate of fuel increase for given pressure decrease.

Abstract: Fuel injection devices are used for injecting fuel into the combustion chambers of compression ignition engines. It is desirable to isolate the mechanical drive for fuel injection timing from the flow path of high pressure fuel to minimize the seepage of fuel into the fluid lubricating the mechanical drive while using only one speed responsive device for both the timing and governing functions. The subject fuel injection apparatus includes a planetary gear arrangement having a ring gear to change the timing phase relationship between a distributor rotor and a delivery passage which communicates the pump section with the rotor. A metering collar is adapted to meter the quantity of fuel delivered by the rotor to the outlet ports. Both the ring gear and the metering collar are mechanically connected to an element of a single flyweight assembly. The metering collar is widely spaced from the planetary gear arrangement to minimize the leakage of fuel into the lubricating fluid.
