Abstract

A method for controlling and regulating the combustion in the combustion chamber of an internal combustion engine, at least one knock sensor detecting a cylinder-specific knocking signal for each cylinder of the internal combustion engine, the knocking signal detected in this manner being fed to an evaluation circuit which reconstructs the combustion chamber pressure characteristic from the detected knocking signal, this combustion chamber pressure characteristic being evaluated for the control and regulation of the next combustion in this cylinder.
