Fuel Distributor: Description and Operation
Fig. 18 Fuel Distributor with Differential Pressure Regulator
As the volume of air entering the engine increases, the air flow sensor plate rises, the control plunger opens and fuel delivery to the injectors is
increased Fig. 18. When air flow decreases, the sensor plate and control plunger drops and less fuel is delivered to the injectors. When the engine is
stopped (no air flowing past sensor plate), the control plunger closes off the fuel distributor metering slot and no fuel is supplied to the injectors.
