Method and device for recognizing uncontrolled combustions in an internal combustion engine

A method for recognizing uncontrolled combustions in an internal combustion engine which occur independently of the ignition by a spark plug.

Beschreibung
Zusammenfassung:	A method for recognizing uncontrolled combustions in an internal combustion engine which occur independently of the ignition by a spark plug. The pressure oscillations in the combustion chamber triggered by the combustion are detected and evaluated. To allow identification at any time of an uncontrolled combustion prior to ignition by the spark plug and/or prior to the normal combustion initiation for a given ignition point, the rotational speed of a crankshaft of the internal combustion engine which is influenced by the pressure oscillations, is evaluated.
