Detection of Diesel Engine Injector Faults Using Acoustic Emissions

By Fathi Elamin, Yibo Fan, Fengshou Gu and Andrew Ball

Abstract

This study investigated the method of identifying injector faults in a JCB 444T2 diesel engine using\ud acoustic emission (AE) technique. Different kinds of injector faults were seeded in the four-cylinder, four-stroke, and turbo-engine. The AE signals recorded from the tests were processed in the angular domain, frequency and joint angular-frequency domain. The results showed that AE could clearly monitor the combustion process of diesel engine because high frequency AE signal measured from engine cylinder head has very high signal-to-noise ratio. Using features in the AE signal, faults of injector can be identified during the operation of the engine
