Abstract: The present study explores the influence of post-injection parameters, namely, post-injection angle and post-injection mass, on a continuous active regeneration trap to mitigate vehicular emissions using diesel enriched by active amyl alcohol from Scenedesmus quadricauda microalgae. From the study, while operating on active amyl alcohol-diesel blend, the maximum de-smoke efficiency for low, medium and high load conditions observed were 67.25%, 55.78% and 46.94% respectively at a post-injection timing of 20°CA aTDC and at a post-injection mass of 2 mg. Furthermore, the maximum de-hydrocarbon efficiency was obtained at a post-injection timing and mass of 10°CA aTDC and 1 mg with a reduction of about 65.45%, 75% and 73.8% for low, medium and high load conditions. However, a 1.36% increase in fuel consumption is observed at late post-injections as compared to diesel fuel. At all cases, simultaneous reduction of particulate smoke emissions and oxides of nitrogen of up to 65.45% and 29% were observed with the complete elimination of carbon monoxide emissions by catalytic oxidation treatment within the after-treatment unit. The novelty of this study is to establish third generation bio-energy as a suitable diesel fuel surrogate for a post-injection activated after-treatment unit.
