A method for calibrating post-injections in a fuel injection system, including a fuel accumulator, of an internal combustion engine, in particular of a motor vehicle, in which it is provided in particular that the calibration of at least one post-injection takes place based on the pressure drop in the fuel accumulator caused by the fuel injection.

Method and device for calibrating post-injections of an internal combustion engine

A fuel injection system for an internal combustion engine in which pressurized fuel is made available in a pressure accumulator and a fuel pressure prevailing in the pressure accumulator is ascertained with the aid of a pressure sensor and in which the fuel enters a combustion chamber of the internal combustion engine through at least one fuel injection device. A slope of a curve, which links a pressure difference in the pressure accumulator during a fuel injection to an injected fuel quantity, is ascertained and the fuel pressure prevailing in the pressure accumulator is inferred from the slope.

Method for operating a fuel injection system

Described is a method for operating an internal combustion engine (), in which method at least one parameter of the exhaust gas flowing in an exhaust-gas duct () is detected by at least one exhaust-gas probe (), wherein the internal combustion engine () is at least temporarily turned over by a starting device (), during which an injection and combustion of fuel does not take place, and during and/or after which the exhaust-gas probe () is adjusted.

Method for operating an internal combustion engine

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:
