Experimental Assessment of Diesel Fuel Injection System Faults Using Vibration Signal Analysis

Abstract

Different tries have been presented to detect the faults of diesel fuel injection systems using vibration signal analysis and to ensure that this strategy is effective in detecting errors. In this paper, an attempt to detect the diesel injection system faults by analyzing its vibration signals using the angular range is presented. The time -frequency band was used to detect a series of faults such as; injections pressure, injected fuel quantity, and injection timing. This technique is useful because it does not need to decode and test the parts in a traditional way to detect faults. Throughout this paper, it has proved the possibility to use these techniques to detect these faults simply.
