Abstract

Switching off a fuel pump of a fuel supply system for the internal combustion engine with the aid of a signal from a retardation sensor of the airbag in the event of a crash in which the motor vehicle is involved is known. To further enhance the safety of motor-vehicle occupants, a method is proposed for an internal combustion engine which has at least one fuel injection valve, a fuel supply system for the at least one fuel injection valve, and a sensor for detecting a crash. After the crash has been detected by means of the sensor, the fuel injection valve is brought into an open position, with the result that fuel is discharged from the fuel supply system of the fuel injection valve into a combustion chamber of the internal combustion engine. The method according to the invention is provided for internal combustion engines with at least one fuel injection valve.
