Abstract
A process for operating an internal combustion engine in which in the event of an incorrect fuel injection, the combustion chamber of the engine is discharged toward the injection side by way of a pressure valve in such a way that by introducing burned exhaust gases into the combustion chamber in lieu of fresh atmospheric oxygen, the combustion is interrupted despite or precisely due to an excess of injected fuel present. The resultant impairment of the drive output is used as a signal to trigger an interruption of the fuel supply or to shut off the engine. This prevents a destruction of the engine as a result of a malfunction of the injection.
