| Abstract |
: |
The development of internal combustion engine always facing with the knock problem., Indeed, the characteristics of a motor engine itself is determined by the knocking issue. In this study, a method of knocking detection through simple microphone sensor has been developed. It incorporates discrete wavelet transformation (DWT) analysis and the regression function of the sound wave envelope to identify the occurrance of knock. After detecting the knock, a 3D engine ignition chart (characteristic) can be created as demonstrated in this paper. |
