Diesel engine is a kind of complex power generating machine, and play an important role in industry, which failure rate is high. How to utilize new science and technology to carry out diesel engine fault diagnosis is a lasting topic. Instantaneous angular acceleration of diesel crankshaft contains a little information for diesel engine fault diagnosing and its power balance evaluating. In this paper the theory and the method of diesel engine fault diagnosis based on angular acceleration measurement are studied. At the same time, the high speed micro-controller AVR8535 which has unique function of automatically capturing the rising or falling edge of square wave is studied, and it was utilized in the diesel engine's crankshaft angular acceleration measuring system. In this paper its software and hardware was designed, which supplied a whole solution to diesel engine fault diagnosis based on instantaneous angular acceleration.
