Combustion event detection is an important issue in internal combustion engine. The combustion is mostly detected by measurement of pressure by a pressure sensor which is mounted in cylinder head. However, the cost of pressure sensor is very high. Therefore, an effort has been made to detect the combustion event in a diesel engine by analysis of sound signal recorded by android mobile. The sound signal carries various frequencies. Therefore, an algorithm based on wavelet packet transform (WPT) has been developed to detect the combustion event in a single cylinder diesel engine.
