| Abstract: | Aiming at the needs of on-line performance monitoring and fault diagnosis, data acquisition system for internal combustion engine based on PCL-818HD data acquisition card was constructed. Conditioning circuit for vibration signal, oil signal, current signal, and voltage signal was designed. Programming method of data acquisition program based on VB and DLL techniques under Windows environment was introduced. Also, the application of fuzzy pattern recognition method on fault diagnosis for each sub-system of internal combustion engine was studied and the comprehensive performance evaluation method for the internal combustion engine based on the D-S evidential theory information fusion techniques was analyzed. |
