High-Pressure Pumps
Bosch High-Pressure Pumps: Precision to Help You Saving Fuel
During direct gasoline injection the high-pressure circuit is fed by the high-pressure pump. In the high-pressure pump, the fuel supplied by the electric fuel pump with a pre-supply pressure of 0.3-0.5 MPa is compressed to the injection pressure of 5-15 MPa.
It thus compresses the fuel to the high pressure level required in the fuel rail. The high-pressure injection valves attached to the fuel rail rapidly meter and vaporize the fuel at high pressure for optimum mixture formation directly in the combustion chamber.
Advantages of direct gasoline injection:
- Reduced fuel consumption of up to 15%
- Up to 5% higher torque
- Spontaneous response behavior
