Effect of Oxygen Enrichment in the Emission Characteristics of Yttria Stabilized Zirconia Coated Diesel Engine with Alumina Nanoparticle Additives
J. Environ. Nanotechnol., Volume 14, No 1 (2025) pp. 366-370
Abstract
This work aims to provide a proper solution for the global warming caused by the emission of IC engines. To cope with the emission standard of current emission norms BS-VI, it is necessary to reduce engine emissions at a considerable level. Oxygen enrichment and alumina nanoparticle additives minimize engine emissions such as hydrocarbon, carbon monoxide, nitrogen oxide, and smoke. For oxygen enrichment, Pressure Swing Adsorption (PSA) methods are used. Oxygen enrichment is done at various oxygen concentrations of 21-29%. Uniform distribution of additives with fuel is done through an ultrasonicator. Yttria Stabilized Zirconia (YSZ) thermal barrier coating controls the increase in engine temperature due to oxygen enrichment and avoids detonation. It was also found that the increase in oxygen concentration from 21% to 25% led to a rise in engine performance and control emissions such as hydrocarbons for about 10-15 ppm and carbon monoxide by 40%. It was also found that nitrogen oxide emission is maintained similarly to that of the diesel engine with the effect of alumina nanoparticle addition. It was also found that increasing the oxygen concentration reduces the OH concentration due to the lack of H atoms.
