摘要

Method for controlling an internal combustion engine comprises deriving a noise parameter from a combustion chamber signal, in which the parameter characterizes the intensity of the combustion noises of the engine. An independent claim is also included for a device for controlling an internal combustion engine. Preferred Features: The noise parameter is produced by filtering the output signal from a combustion chamber pressure sensor. Two FIR deep passes are used for the filtering. The noise parameter is fed to a regulating unit (140).
