PERFORMANCE TEST ON FOUR STROKE DIESEL ENGINE WITH MODIFIED EXHAUST SILENCER MUFFLER DESIGN

The main objective of the study has been evaluate the performance measurement of four stroke diesel engine with modified exhaust silencer muffler design. The modified muffler designed by CERO software version 2.0 as per standard dimension in the chart and it?s optimized for expected dimension. The article focused on the main characteristics of attenuation of sound wave reduction by updated design implemented on the internal cross section of muffler and experimented by the performance test on four stroke diesel engine and in addition of engine efficiency are compared with the existing model in term of brake thermal efficiency, indicated thermal efficiency, mechanical efficiency, brake specific fuel consumption, temperature and pressure measurement of the engine.
