“NOISE SOURCE IDENTIFICATION & REDUCTION IN SINGLE CYLINDER DIESEL ENGINE”

Sandip B. Chaudhari and Sachin V Lomte

In India, Three Wheeler is being used as a mode of public transport & also as a source of income for Bottom of Pyramid (BOP) segment. Since BOP segment is very price sensitive, low cost single cylinder air cooled diesel engine being used as prime mover for three wheeler vehicle. High noise & vibration is inherent feature of diesel engine & it is predominant in single cylinder diesel engine. In order to maintain low cost of product, less attention is given on overall noise of vehicle. Engine noise is major contributor for vehicle noise. As on today only regulatory requirements are met in terms of noise. Recently customer demands are increasing & also to sustain in competitive market, most of the engine manufacturers have started working on engine noise reduction. So the research work need to identify for reduction of engine noise in single cylinder air cooled diesel engine. Also Literature survey need to carry out to identify the methodologies of noise source identification & remedies to reduce from identified source. So this paper gives, engine selection, experimental test set up preparation to identify engine noise sources is completed. Overall study clearly indicates that it is possible to reduce engine noise to the tune of at least 1.5 dB; scope exists for overall reduction of engine noise
