AB Injection process in diesel engines is a key to control engine performance parameters such as torque and power as well as to control noise and emissions from engine. Condition monitoring of injector is an important methodology for obtaining information about fuel injection process. However it is difficult to monitor the injector motion using air borne engine acoustic signals. In this work adaptive filtering has been used to study the injector impacts using condenser microphone located at a distance of 0.25 m from the engine rig on a array structure. The data obtained was filtered and processed in MATLAB 7 software. Various injection pressures were used and time frequency Wigner Ville Function was used to study the injector impacts.
