Abstract
The Discrete Wavelet Transform (DWT) is a new way to analyze gas flow measurements in engine cylinders. The DWT technique differs significantly from the Fast Fourier Transform (FFT) in that with the former, the analysis of information can be done in both the time domain and frequency domain. The basic theory of wavelets is presented and the use of DWT is demonstrated on information derived from laser Doppler velocity (LDV) measurements for different geometrical configurations of combustion chambers in a natural gas converted truck engine.
