Experimental Investigation on The Performance and Emission Characteristics of A Single Cylinder Di Diesel Engine Using Mahua Biodiesel, Blends and Diesel By Varying Number of Injection Nozzle Holes

Fuel injection parameters play an important role in diesel engine performance for obtaining proper combustion. The performance and emission characteristics of diesel engine depend on many parameters. 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 as 2 and 3 hole.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.
