Abstract
Pressure as a function of the crankshaft angle plays an important role in the dynamics of spark ignition (s.i.) engines because it determines the power output of the cylinders. The form of this curve indicates the status of the combustion process in the cylinder and can be used as a good diagnostic signal for engines. In this paper, some methods to recover the cylinder pressure waveform, by using information included in the vibrations taken on the engine block, are presented. The methodologies, here presented, use the Frequency Response Function or the Hilbert-Wiener filter and can be applied both in the steady state or in free acceleration running. The good results obtained in this first stage of study make the authors confident that this methodology could be used to detect the status of the cylinder combustion.
