VIBRATION ANALYSIS OF DIESEL'S COMBU SION BASED ON FRACTAL THEORY

LIU LI; LI LI; SHEN YANHUA (College of Resources Engineering, USTB, Beijing 100083, PRC)  
Self-similarity of diesel's combustion process is analyzed.Vibration signals of combustion are picked up from the cylinder wall,and correlation fractal dimension D is calculated by using G - P algorithm in fractal theory. Parameters which influence D are investigated.At the same time, D can present cylinder's combustion condition to some extent.Thus,D can be used as a diagnostic parameter and used in diesel's fault diagnosis.
