Abstract:
A method for handling uncontrolled combustions in an internal combustion engine of a motor vehicle, the uncontrolled combustions occurring independently of the ignition by a spark plug and being detected in or at the internal combustion engine. To allow a rapid yet reliable reduction of uncontrolled combustions in an internal combustion engine in order to protect the internal combustion engine from damage, the number of detected uncontrolled combustions in a monitoring period is determined and compared to a threshold value. A temperature in a combustion chamber of the internal combustion engine is dropped if the threshold value is exceeded.
