Experimentation on Performance and Emission Characteristics of Nerium - Water Emulsion with Fuel Additive in DI Engine

Abstract

Abstract— In this experimental work, performance, and emission parameters of Nerium - water emulsion (5%water), Nerium - water emulsion (10%water), Nerium - water emulsion (15%water), Nerium - water emulsion (5%water + 1%DEE), Nerium - water emulsion (10%water + 1%DEE), Nerium - water emulsion (15%water + 1%DEE) has tested in a direct njection (DI) diesel engine. The fuel additive is di-ethyl ether (DEE). A single - cylinder, air cooled diesel engine has used as an experimental apparatus. During this test, brake thermal efficiency, specific fuel consumption, and pollutant toxic emissions of nitrogen oxide, hydrocarbon, carbon monoxide, carbon-di-oxide and smoke are measured. Nerium-water emulsion (5%water + 1%DEE) gives the higher brake thermal efficiency of 4.94%, lower specific fuel consumption of 2.31%, and brings down the discharge characteristics of carbon monoxide, hydrocarbon, carbon-di-oxide, nitrogen oxide and smoke when compared to the diesel.
