Experimental Investigation on Performance and Emission Characteristics of Karanja Oil Biodiesel with Di-Ethyl Ether, Ethylhexyl Nitrate and Methanol 2023-28-0029

Air pollution is one of the biggest issues facing the planet today. One of the major sources of environmental pollution is car emissions. Reduced use of fossil fuel signals the need to switch to other fuels. Every nation in the world is making numerous efforts to reduce the pollution that vehicles are responsible for. Utilizing alternative fuels effectively can reduce air pollution. Decreased fuel consumption results from increased use of biodiesel. For this study, biodiesel made from karanja oil was combined with additives like methanol, diethyl ether, and ethyl hexyl nitrate (EHN). B10, B15, and B20 blends are created in various compositions. For comparison, several fuel attributes for the aforementioned mixes and diesel were discovered. Biodiesel’s viscosity has been significantly lowered to improve mixture preparation and has a higher calorific value than base fuel. The testing for the aforementioned mixes was carried out on a VCR-style CI engine. Analysis was done on the performance parameters heat release rate, brake thermal efficiency, brake power, and indicated power. B10 has a little greater brake thermal efficiency than diesel fuel (32.57% vs. 31.63%, respectively). The effects of different pollutants, such as HC, CO, CO₂, and NOx emissions, were compared to diesel fuel emissions. Compared to pure diesel, there is a reduction in HC, CO, and smoke emissions. However, NOx is more abundant than pure diesel.
