Tewari, P.C.Pankaj Kumar2022-12-262022-12-262022-09https://krishikosh.egranth.ac.in/handle/1/5810190800Energy is a fundamental component of social and economic development. A nation's energy strategy aims for productivity and security, as well as providing environmentally friendly access and achievement of primary resources for energy generation. Petroleum fuels will continue to play a dominant role in our country's energy sector in the coming decades. However, conventional fuel resources are limited, non-renewable, and polluting, and should thus be used with caution, whereas renewable energy sources are indigenous, non-polluting, and abundant. As a result, their use should be encouraged in any way possible. The aim of this present work is to blend wintergreen biofuel with diesel and diethyl ether in the proposed percentage and to test performance parameters such as brake power, fuel consumption, brake specific fuel consumption, brake thermal efficiency, and emission characteristics (exhaust temperature, smoke density, exhaust gas emissions) experimentally on 3.7 kW rated power, single cylinder four stroke compressed ignition engine. The current study led to the conclusion that wintergreen oil blending in diesel is restricted to 30% for comparable performance and emission characteristics with diesel fuel. Increasing wintergreen biofuel proportion led to increased performance characteristics such as BTE, BSFC and reduced CO emissions and decreased smoke density. It is concluded that wintergreen oil blended 20% in diesel gives best performance and emission characteristics at all loads.EnglishThesis
