Assessment of performance, combustion, and emission characteristics of single cylinder diesel engine fuelled by pyrolysis oil + CeO ₂ nanoparticles and 1-butanol blends

Abstract

This experimental work focused on trials on diesel engines using Pyrolysis blends. The novelty in this work is the addition of cerium oxide additives with 1-butanol as an ignitor. The blends used were D100, 90D7WPO3B + 25 ppm CeO2, 85D10WPO5B + 50 ppm CeO2, 80D13WPO7 + 75 ppm CeO2 and 100WPO + 100 ppm CeO2. The results were outstanding as BTE is good for the fuel 90D7WPO3B + 25 ppm CeO2 by 36.2%, which is 12.25% greater than diesel, BSFC is better for the blend 90D7WPO3B + 25 ppm CeO2 by 0.22 kg/kWh, and maximum in-cylinder pressure obtained for 90D7WPO3B + 25 ppm CeO2 blend rated as 66.45bar; and maximum HRR is obtained for 85D10WPO5B + 50 ppm CeO2 blends by 84 J/ deg CA, BSEC of 85D10WPO5B + 50 ppm CeO2 blend is lower next only to diesel by 12.5 KJ/kWh, NOX emission minimum for 100WPO + 100 ppm CeO2 blends rate of 12 g/kWh, 14.2% lower than diesel, and lowest CO is attained for blend 80D13WPO7 + 75 ppm CeO2 blends at a rate of 0.8 g/kWh, 27.7% less than diesel, CO2 is minimum for blend 80D13WPO7 + 75 ppm CeO2 rate of 5 g/kWh; 18.03% less than diesel and HC is minimum for blend 100WPO + 100 ppm CeO2 blend rate of 0.18 kg/kWh; Which is 40% lower than diesel.
