Abstract

Alternative fuels have garnered significant attention due to the depletion of petroleum sources and growing environmental concerns. Biodiesel, a renewable fuel, holds potential as a viable substitute for fossil fuels. Recent advancements in nanotechnology have made nanoparticle fuel additives for internal combustion engines feasible. Previous research has shown that these additives can enhance engine performance. In this experimental study, we investigated the effects of incorporating aluminium oxide nanoparticles (Al2O3) into a JB30 fuel blend (30% Jatropha biodiesel + 70% diesel) to assess potential performance improvements and reduced noise emissions. Our tests employed a 4-stroke, single-cylinder diesel engine operating at a constant speed of 1350 rpm. The JB30 blend was subjected to a 50 ppm dose of Al2O3 nanoparticles using an ultrasonicator. Results indicate that brake-specific fuel consumption (BSFC) improved for the DF70JB30 blend and further improved for the DF67JB30 blend with Al2O3 nanoparticles. Compared to pure diesel fuel, the brake thermal efficiency (BTE) increased by 3.77% for DF70JB30 and by 3.82% for DF67JB30Al2O3. Noise emissions, a crucial factor influenced by the fuel type, were lower for all blended fuels compared to pure diesel fuel (DF). The addition of nanoparticles also contributed to a reduction in the combustion pressure rise rate, resulting in decreased combustion noise. Based on these findings, it can be concluded that both the binary blend DF70JB30 and the ternary blend DF67JB30Al2O3 can be used in diesel engines without necessitating any adjustments. However, DF67JB30Al2O3 demonstrated superior outcomes when compared to DF70JB30.
