Abstract
A method and an arrangement for evaluating the combustion operations in an internal combustion engine with a model is suggested. The model takes a time-dependent transfer between pressure and structure-borne noise as a basis for the relevant low frequency oscillations and only individual components of the reconstructable pressure signal are used for the determination of combustion-relevant parameters and conditions. Independence of engine speed is achieved with the realization of the time dependency with an angular-dependent transfer function.
