Performance Characteristics of Four Stroke Diesel Engine Using Bio Diesel Obtained From Peanut Oil

Abstract

In the transportation industry, many alternative fuels have already seen commercial success, including biodiesel, liquefied petroleum gas (LPG), compressed natural gas (CNG), and alcohol. Rubber seed oil is combined with diesel in the current work and utilized as an alternative fuel for CI engines. Trans-etherification is a chemical process that can turn peanut oil into bio-diesel. The technique of mixing has resulted in gasoline blends with various ratios. Each blend's fuel characteristics are identified. A four-stroke diesel engine with a mixture of diesel and peanut oil was used for the load test. Based on the engine's experimental findings, performance metrics like power, specific fuel consumption, thermal efficiency, mechanical efficiency, and mean effective pressures are calculated and compared. At various loads, the comparative graphs are drawn. Through this work, the viability of employing alternative fuels in diesel engines has been highlighted, particularly the possible use of peanut oil as bio-diesel.
