An Experimental Investigation on Diesel Engine Performance using Moringa Olifera Biodiesel with the Effect of Different Injection Pressures

Increasing cost of petroleum diesel and environmental degradation due to automotive pollution, forces the researchers to search an alternate fuel like biofuel and biodiesel for diesel engine. The biodiesel is produced from Moringa oil by tranesterification process. In the present work, test was conducted to study the performance, emission and combustion characteristics of a diesel engine using Moringa oleifera oil methyl ester- diesel blend (B25: 25%MOME + 75% Diesel) with different injection pressures like 200bar (original), 220bar, 240 and 260 bar at different operating conditions. The results revealed that the Brake thermal efficiency, brake specific fuel consumption were calculated and the emissions parameters like Carbon monoxide, unburnt hydro carbon, Nitrogen oxide and Smoke opacity were and analyzed and compared with standard diesel.
