ABSTRACT:
A method for correcting a measured cylinder pressure of an internal combustion engine, in which a cylinder pressure sensor is connected to a combustion chamber via a duct, disturbing portions resulting from whistle oscillations being suppressed by determining an oscillation frequency of a gas oscillation caused in the duct during a power stroke and filtering the measurement values of the cylinder pressure sensor using a band-stop filter having the previously determined oscillation frequency.
