Abstract

A Natural Gas Vehicle or NGV according to Wikipedia online dictionary (Internet reference,02/08/2008) is an alternative fuel vehicle that uses compressed natural gas (CNG) or, less commonly, liquefied natural gas (LNG) as a clean alternative to other automobile fuels. NGVs are standard vehicles that have been modified to run on CNG and there are three types of NGV engines which are Dedicated, Bi-Fuel and Dual Fuel engines. As any other engines, the NGV engines are also producing some noise. In common use, the word noise means unwanted sound or noise pollution. Therefore, this report is mainly on the research to determine the noise level of NGV engines and compared the differences between both petrol and diesel engines. There are several engines which used the application of NGV which have been totally proved to save the fuel and money. Therefore, the main aim for this research is that to identify its sequences and merely focused it from the noise level area in the aspects of safety, durability and stability that might come from the usage of NGV. This research could be done by collecting the noise level data in experimental test using the noise level detector on several engines including NGV. Besides, the differences set of data will be studied, compared and analyzed to find out its sequences of safety, durability and stability so that the result that will be obtained afterwards might be useful in further studies of the NGV improvements system.
