Abstract
A novel nanofuel is formulated using aluminum oxide (alumina) nanoparticles (AONs) in neat plastic oil (PO). A light-duty compression-ignition engine is used in the present investigation to analyze the effect of a 100% plastic nanofuel under different concentrations of nanoparticle on performance, combustion, and emission characteristics. The modified fuels used for conducting the experiment were formulated by mixing PO with 100, 150, and 200 mg/L of AON. The results of the physical and chemical properties of neat PO were significantly improved, in addition to AON. The nanofuels exhibited lower in-cylinder pressure, delay period, and combustion duration than that of neat PO operation. The performance analysis revealed a 10.3% increase in thermal efficiency for PAN200 nanofuel compared with PO and it was almost the same as that of conventional diesel fuel. The emission levels of HC, CO, and smoke for PO-based nanofuels were reduced significantly at all brake mean effective pressure values, whereas the reduction in the NOX emission was only marginal. At full load, the emission of smoke, HC and CO of the PAN200 nanofuel were lower than the diesel operation. Overall, the engine fueled with nanofuel exhibited superior characteristics compared to that of neat PO operation.
