Role of Additives on Emission Characteristics of Methyl Ester in Constant Speed Diesel Engine

Abstract:

In this study, the outcome of adding n-butyl alcohol to jatropha methyl ester on the emissions characteristics of compression ignition engines is investigated. Single cylinder diesel engine was fuelled with n-butyl alcohol / jatropha methyl ester blends. The doping volume of n-butyl alcohol to jatropha methyl ester blends was in the range of 10, 20 and 30%. Emission parameters such as Hydro carbon (HC), Carbon monoxide (CO), Nitrogen oxides (NOX) and Smoke emissions were examined at different load conditions. The engine speed was maintained constant throughout the trail. This work resulted in a significant reduction in reduction in all the emissions. Addition of n-butyl alcohol as additive improves the rate of combustion, mixing and vaporization of the blends with air and reduces the emissions associated with it. Further, it can be used in the existing engine with any modification. This also results that the addition of n-butyl alcohol to jatropha methyl ester reduces the emissions associated with it. Further, no damage to engine components was observed during the trail.
