Abstract
A muffler (or a silencer) is one of the important parts of an engine system used in an exhaust system to reduce the exhaust gas noise level. Although its’ primary role is to reduce the exhaust gas noise level, but it can also play a role in the car’s overall performance. An engine is able to generate more power faster, if it is able to get rid of all of the exhaust gases. By their nature, mufflers restrict the exhaust gases or create back pressure which has a negative effect on engine efficiency. The literature review reveals that it depends upon various factors such as muffler geometry, number of perforations and its’ diameter; etc. The objective of this study is to achieve a good fuel economy. The performance of the muffler is assessed by analyzing average fuel consumption, average mechanical efficiency and firing. The tests are run over the muffler before and after its’ modifications with the help of a diesel engine. The results obtained from first testing are graphically plotted and are compared with the results from second testing, containing the required modifications, which too are graphically plotted. After the comparison, it is found that the modified muffler has achieved good fuel economy with increased overall average with smooth firing, also the problem of black soot is reduced which overall increased its’ lifespan.
