Diesel Engine Fault Detection Using Vibration and Acoustic Emission Signals

Abstract

The vibration and acoustic methods are among the most useful techniques for monitoring the conditions of machines. The  internal combustion engine one of machine which has the reciprocating parts can cause progressive damage that ultimately affects the engine efficiency. Therefore, following the performance of these parts can save a lot of time, money, effort and maintain the acceptable performance of the engine. This paper gives a brief review and evaluates the most of effective monitoring techniques to the internal combustion engine based on acoustic and vibration emissions.
