Effect of Al2O3 Nanoparticles on Performance and Emission Characteristics of Diesel Engine Fuelled with Diesel–Neem Biodiesel Blends

Indagation in the sphere of nanoparticle utilisation has provided commendatory upshots discrete areas application varying from medicinal use to environmental degradation alleviation. This study incorporates alumina nanoparticles as additives diesel and biodiesel blends. The prime objective present was scrutinisation denouement Al2O3 incorporation diesel–biodiesel blends on a engine’s performance emission characteristics. Test fuel samples were prepared by blending different proportions dispersing two concentrations (25 50 ppm) diesel. Dispersion made without stabiliser meet real-world feasibility. High-speed shearing employed blend diesel, while dispersed ultrasonication. so devised tested using single-cylinder engine at fixed RPM applied load for three compression ratios. Upshots brake-specific consumption (BSFC) brake thermal efficiency (BTE) measured with LabView-based software, whereas CO emissions unburnt hydrocarbon (UBHC) computed an external gas analyser attached exhaust vent engine. Investigation revealed that inclusion culminates amelioration along alleviation deleterious Furthermore, assisted dwindled attributed blending. More favourable results obtained higher ratios compared lower ones. Reckoning evinced is lucrative introduction fuels boost dwindle engines.
