Assessment of performance, combustion, and emission characteristics of single cylinder diesel engine fuelled by pyrolysis oil + CeO₂ 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 CeO_2. 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, NO_X 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.
