Abstract
The increasing in popularity of Light Commercial Vehicles (LCV) segment is an emerging trend in the commercial vehicle industry. LCVs are very efficient and cost-effective for transportation of materials and good on short distances or loads of lesser weights. Sensing the market potential, many auto companies have developed LCVs recently.
Since LCV segment is price sensitive, low cost single cylinder water cooled diesel engine being used as prime mover. High noise & vibration is inherent feature of diesel engine & it is predominant in single cylinder diesel engine. In order to retain low cost of product, less attention is given on overall noise of vehicle. Also, it is challenging to meet the regulatory limits of Pass-by Noise (PBN) for this category of vehicle.
This paper is a development work done for pass-by noise reduction of a diesel powered single cylinder LCV vehicle. A prototype vehicle needs to meet the legislative pass-by noise requirement when tested as per IS0 362 / IS 3028. Initial Pass-by noise test of the proto vehicle clearly demands to reduce the Pass-by noise by 2-3 dB which in turn required to carry out the Noise Source Identification during Pass-by noise test. Pass-by Noise Source Identification resulted with various sources contributing to increase in noise levels. Development iterations were conducted on the vehicle to achieve the significant Pass-by noise reduction.
