Abstract

In a fuel system of an internal combustion engine, the fuel quantity injected into a combustion chamber is a function of an activation period, during which a fuel injection device is activated. A pressure sensor detects the pressure in the fuel rail and provides a signal. The pressure in the fuel rail may be regulated to a setpoint pressure using a setting unit and employing the signal provided by the pressure sensor. The following method is provided for testing the fuel system:
