Abstract
The present work focuses on various vibro-acoustic signals techniques that can monitor malfunctions in Internal Combustion Engines (ICEs). Recent works by other authors have focused on various reciprocating machines including compressors no attempts has been deal with IC engines. This paper gives a summary of the generation mechanism of sound and vibration in Engines. An overview of the monitoring and diagnostic techniques base on noise, pressure an vibration signatures is also discussed. Various fault conditions are described which affect ICEs. Measuring of acoustic signals has non-intrusive behavior with capability of detecting airborne transmission paths faults. In view of industrial needs to reduce the maintenance costs monitoring of vehicle operations, the present work can be a useful guide for engineers for understanding types of faults so as sufficient time is obtained to process reliable and information.
Highlights
Monitoring of in cylinder pressure developed, noise, vibration andacoustic signals are some of these techniques commonly used for analysis of working of machines [1]
Winger –Ville distribution (WVD), Born –Jordan distribution (BJD) and Choi-Williams distribution (CWD) are commonly used Bilinear Time-frequency Distribution (BTFD) methods [7]. When these methods are applied to transient signals, large ripples are produced on the envelopes which may lead to loss of information [8]
The combustion and piston motion noise have major contributions, it is necessary to analyze in more depths these aspects of engine noise and vibration acoustics
