Abstract

In this study, the effect of intake air enrichment on the performance
and emission characteristics of a single-cylinder direct-injection diesel
engine fueled with non edible oil namely Cardanol—diesel-methanol
blend (B20M10) are investigated. With increase of intake air oxygen
concentration, CO and HC decreased while brake thermal efficiency and
NOx considerably increased. The maximum Brake Thermal Efficiency of
33.98% is obtained for B20M10 with 7% oxygen enrichment of intake air.
Maximum NOx emission 20% is obtained for B20M10 with 7% oxygen
enrichment for the full load condition. Decreases of 20% and 14.5% in
CO emission are obtained for B20M10, over B20M10 with 7% oxygen
enrichment, where as 76.8% and 74% decrease in hydrocarbon emission
is obtained over B20M10 without oxygen enrichment.
