Title:
METHOD AND DEVICE FOR HANDLING UNCONTROLLED COMBUSTION IN AN INTERNAL COMBUSTION ENGINE OF A MOTOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2011/117122
Kind Code:
A3
Abstract:
The invention relates to a method for handling uncontrolled combustion in an internal combustion engine of a motor vehicle, the uncontrolled combustion occurring independently of ignition by a spark plug and being detected in/or on the internal combustion engine. In order to enable uncontrolled combustion in an internal combustion engine to be reduced rapidly but nonetheless reliably, in order to protect the internal combustion engine from damage, the number of occurrences of uncontrolled combustion detected in a monitoring period is determined and compared with a threshold value, a temperature in a combustion chamber of the internal combustion engine being lowered if the threshold value is exceeded.
