Method for determining pressure values in cylinder of e.g. internal combustion engine, involves determining correction values in dependent upon pressure measuring values, and utilizing correction values to find pressure values

摘要

The method involves measuring pressure measuring values i.e. pressure curves, using pressure sensors (24). Correction values are determined in dependent upon the pressure measuring values and an operating cycle condition and/or a combustion condition of a combustion chamber (12) i.e. cylinder, of an internal combustion engine (10). The correction values are utilized for determining the pressure values. A correction function is provided for assigning the correction values in dependent upon the course of the operating cycle and/or the combustion condition of the combustion chamber. Independent claims are also included for the following: (1) a computer program that is programmed for execution of the method for determining pressure values in the combustion chamber of the internal combustion engine (2) a control device for controlling the internal combustion engine.
