Experimental Investigation On The Performance And Emission Characteristics Of A Single Cylinder Di Diesel Engine Using Mahua Biodiesel, Blends And Diesel On Adding Dee By Varying Number Of Injection Nozzle Holes

Diesel engines have main contribution in air pollution by exhausting gases such as carbon monoxide, unburned hydrocarbons, oxides of nitrogen and other harmful gases or components. The formation of these harmful gases can be reduced by the use biodiesel as alternative fuel. This paper aims to present the experimental studies on the performance and emission characteristics of Mahua oil methyl ester (MOME), blends and diesel as a fuel for a single-cylinder direct injection diesel engine. Experiments have been carried out to study the effects of performance characteristics like brake specific fuel consumption (BSFC), brake thermal efficiency (BTE), and emissions such as hydrocarbon (HC), carbon monoxide (CO), carbon dioxide (Co2) oxides of nitrogen (NOx) in a diesel engine by varying number of injectors nozzle holes. Mahua oil methyl ester blends prepared are M20[18%biodiesel+2%DEE+80%diesel], M40[38%biodiesel+2%DEE+60%diesel], M60[58%biodiesel+2%DEE+40%diesel] and 100% biodiesel. Testing is carried out by varying number of holes of nozzle as 2 hole, 3 hole and 4 hole nozzle at constant engine speed 1500rpm. Increasing the number of nozzle holes improves the performance of diesel engine fueled with MOME in terms of increased BTE, reduced emissions like HC, CO, CO2. However, NOx emission increases with increased number of holes.
