Influence of the Metallic (SiO) and Non-metallic (Rice Husk) nano additives blended with 2-ethylhexyl nitrate on the Engine Characteristics of CRDI Diesel Engine

This study examines the impact of metallic (Silicon oxide) and non-metallic (rice husk) nano additives on 2-ethylhexyl nitrate blended with diesel on a common rail direct injection diesel engine. Using a homogenizer and an ultrasonicator, the nanoparticles (SiO and RH) were selected in different proportions (40, 80 and 120 ppm), and the biodiesel is made by combining 50% diesel, 50% mahua oil and 15% ethylhexyl nitrate. The analysis considered the performance, emission, and combustion parameters. The SiO additive propensity to function as an oxygen buffer and the catalytic breaking of hydrocarbon chains are the major causes of this rise in thermal efficiency (7.82%). Also, it can be noted that both RH40 and RH80 blends exhibit a considerable rise in the thermal efficiency value. The better combustion process brought on by the inclusion of the rice husk additive is the primary reason for the rise in efficiency (13.2%). This is due to the better characteristics like calorific value, viscosity, density, fuel mixing, atomization, etc., promote combustion within a cylinder.
