Mechanical high-pressure fuel pumps provide the required high injection pressure of approx. 120 to 250 bar in the fuel rail. They work according to the piston pump principle and are driven by a tappet from the camshaft.
The performance of a high-pressure pump is designed to supply more fuel than the engine requires at any time and in any operating state.
The fuel pump in the tank supplies the fuel in the low-pressure system to the high-pressure pump. The fuel pressure in the low-pressure system is between 0.5 and 5 bar during normal operation.
In addition to the existing range of Pierburg high-pressure fuel pumps, Motorservice offers a large number of other components in the fuel supply sector. These include fuel pressure sensors, fuel delivery modules, fuel pressure regulators, electric and mechanical fuel pumps, fuel / vacuum tandem pumps and fuel check valves – a comprehensive product range for cost-effective repairs.
