Abstract

A gasoline engine condition monitoring uses an accelerometer to monitor engine. Typically, detected vibration signal is included considerable noise (<1000 Hz) that related to moving parts and mechanisms of rotating machine. The use of acoustic emission signal can help to clearly identify various processes in the gasoline engine cycle. This study was used acoustic emission sensor to investigate mechanisms of 4-stoke, 4-cylinder, Suzuki gasoline engine with capacity of 1600 cc such as the operation of intake and exhaust valves, clearance intake and exhaust valve faults and injector faults when engine was running with no load and load of 10 and 20 Nm. It is found that acoustic emission signal can be used to monitor engine operations and also can be used to predict various simulated engine conditions of normal and abnormal engines with better result than vibration signal.
