Experimental research on performance and emission characteristics of country borage methyl ester - Diesel blend in a compression ignition engine

Abstract

An Experiment has been conducted performance and emission and combustion characteristics of a single-cylinder by using country borage methyl ester (CBM) and diesel blend in a direct injection at a constant speed diesel engine. In the past few years, the investigation on the biofuels has been considerable interest by virtue of their unique physical and chemical properties. This experiment works involves the usage of country borage methyl ester and diesel blend, to study its effect on performance, combustion and emission characteristics. Diesel and country borage methyl ester fuel blends are 20%, 40%, 60%, 80%, 100%, and varying load of 25% increment from no load to full load. The experiment was carried out for engine performance parameter such as brake thermal efficiency (BTE) of CBM 20 blend was slightly higher 3% than that of diesel. And the engine emission parameters such as hydrogen emissions is reduced 22% for CBM 20 and 32.5% for CBM 40 blend. And NOx emission was slightly increased by 5% for CBM 20 and 8% for CBM 40.
