Impact of Alcohol and Gutter Oil Emulsion in Single Cylinder Compression Ignition Engine

Abstract

Although the world's natural fossil fuel supplies are running low, the demand for fuel is rising due to rapid urbanization and population growth. The direct use of spent cooking oil in diesel engines has gained acceptance to lessen global reliance on fossil fuels, particularly in the transportation sector. As a result, carbon and lacquer deposits have worn down and damaged the engine. Furthermore, deposits on the piston crown may become extremely persistent due to the increased heat generated by contemporary diesel injection systems. In a single chamber CI motor, three distinct fuel tests were put through a 200-hour endurance test: DF83WCO7Pe10, which is a blend of 65% diesel, 20% waste cooking oil, and 15% n-pentanol, and diesel fuel (DF), which is a mixture of 95% diesel and 5% waste cooking oil. This review examined the effects of DF, the ternary fuel mix DF65WCO20Pe15, and the twofold fuel mixes DF93WCO7 on cylinder crown stores. According to the investigation, visual inspection revealed some deposit deposition on the piston while it was running with all tested fuel types. Energy dispersive X-ray spectroscopy (EDS) and scanning electron microscopy (SEM) revealed that an engine powered by DF93WCO7 left more carbon deposits on and around the piston surface than one powered by DF83WCO7Pe10.
