Abstract

Enter In the current study, an effort has been made to use biodiesel together with nano sized additives as combustion promoter and as an emission inhibitor. The study investigates the influence of volume concentration of cerium oxide (CeO2) nanoparticles (NPs) on the engine combustion and emission at different load conditions. Engine experiments are conducted in a stationary diesel engine with B20 (20% waste cooking oil biodiesel and 80% mineral diesel) fuel blend and CeO2 NPs with volume fractions 40, 80 and 120 ppm. The performance parameters such as brake specific energy consumption (BSEC), cylinder pressure and rate of heat release, emission parameters like carbon monoxide, unburnt hydrocarbon, smoke, oxides of nitrogen and carbon dioxide are measured and analyzed. It is seen that, when CeO2 NPs are added to the base B20 fuel, the performance of the engine is improved in terms of reduced BSEC, increased cylinder pressure and higher heat release rate. The tail pipe emissions such as carbon monoxide, unburnt hydrocarbon, smoke and oxides of nitrogen are reduced compared to neat B20 biodiesel operation. The optimum engine performance is obtained for B20 biodiesel with 80 ppm CeO2, whereas major reduction in the engine emissions is observed for B20 biodiesel with 120 ppm CeO2.
