A Study for the Effect of Antioxidant EDA and Aluminium Hydroxide Additives to Mitigate CO and NOx Emissions in Biodiesel–Diesel Blend Fuelled CI Engine

Abstract

This paper studies the effect of using Jatropha biodiesel–diesel blends as fuel in single cylinder CI engine on the most obnoxious CI engine exhaust emissions NOx and carbon mono oxide (CO). Antioxidant ethylene diamine (EDA) and a novel additive aluminium hydroxide (Al(OH)3) have been used as additives with fuel in different concentrations. Aluminium hydroxide is a new material, not yet referred in journals, which chemically decomposes into alumina and water at high temperature. The test results found were promising in reducing the NOx and CO emissions. And aluminium hydroxide as expected has been proved to be an cost effective alternative to the alumina nanoparticles along with the advantages of water in mitigating emissions.
