Abstract

The main aim of automobile engineers is to increase the performance and reduce emission of the SI engine and one of the methods of doing it is by turbocharging. In this study, a 150 cc single cylinder two stroke SI engine is used to conduct performance and emission analysis with and without turbocharger. The turbocharger used was a TEL make used in Tata Indica. The brake horse power and brake thermal efficiency are increased by 12% and 21.83% whereas specific fuel consumption is reduced by 22% for turbocharged engine compared to the standard engine. CO emission is reduced by 34.31% and 39.17%, HC emission is reduced by 10.46% and 64.22% at idling and at high engine speed respectively for turbocharged engine when compared to the standard engine.
