Abstract: Many research works are focusing on novel techniques to replace crude‐based fuels due to the increasing demand for sustainable fuels and decreased emissions from automobile vehicles. The current study is mainly focused on the effect of aluminum nitrate (Al(NO3)3) nanoparticles on the performance and emission characteristics of coconut fatty acid distillate biodiesel (CFADB) in a diesel engine. In this novel approach, nitrate‐based aluminum nanoparticles having excess oxygen influence combustion improvement, lowering emissions compared to utilizing metal or oxide‐based nanoparticles. The different test fuels such as diesel, B20, B100 and their blends with Al(NO3)3 nanoparticles (50 ppm and 100 ppm) were investigated on a single‐cylinder engine with a constant speed of 1500 rpm at various loads. The B20 + Al(NO3)3 100 ppm blend exhibited a 12.16% higher brake thermal efficiency than diesel. In the case of emissions, carbon monoxide (CO), hydrocarbon (HC) and smoke are decreased by 47.3%, 44.6% and 34.6% respectively. Moreover, it is observed that the higher oxides of nitrogen (NOx) emissions increased by 57.03% at peak load. The Al(NO3)3 nanoparticles have excessive oxygen and catalyst characteristics in their structure which has the ability for combustion improvement and lower emissions. The research findings confirmed the feasibility of CFADB‐ Al(NO3)3 combinations as cost‐effective, eco‐friendly, and renewable alternatives for diesel engines. [ABSTRACT FROM AUTHOR]
