Abstract
⺠A novel approach to detect valve and combustion key events in internal combustion engines is presented. ⺠The measured in-cylinder pressure is used as an input. ⺠The method is based on the polytropic change of state during compression and expansion. ⺠A polytropic volume is calculated which can easily and intuitively be compared with the known real cylinder volume. ⺠Events are detected using wavelet transformation.
