System Configuration of Supply Pump
1. Outline
The fuel that has been drawn up from the feed pump located inside the supply pump is pressurized to the required pressure. The plunger in the pump generates the required injection pressure. Read more System Configuration of Supply Pump

Gasoline Engine Fuel System/ Fuel Pump and Pressure regulator
The fuel is taken from the fuel tank by the fuel pump and sprayed under pressure by an injector. The fuel pressure in the fuel line must be regulated to maintain stable fuel injection by the pressure regulator Read more Gasoline Engine Fuel System/ Fuel Pump and Pressure regulator
Feed Pump and Regulating Valve
1. Feed pump
The vane type feed pump consists of four blades and a rotor. The rotor is driven by the drive shaft, and the blades push against the inner wall of the pressure chamber due to centrifugal Read more Feed Pump and Regulating Valve
