Experimental investigation of methyl ester derived from distillate of coconut oil as eco‐friendly fuel in diesel engine

Abstract

AbstractFor a thorough investigation of the combustion, performance, and emission characteristics of coconut oil distillate biodiesel under various engine loads and a constant engine speed of 1500 rpm, a Kirloskar 4‐stroke, single‐cylinder, the air‐cooled diesel engine is used. A total of three fuel samples, such as 100% biodiesel, B20, and B30 biofuel are used respectively. There is a 5% increase in brake thermal efficiency (BTE) for biodiesel and its blends as compared to diesel. The HC, CO, and Smoke are reduced except NOx. Reduction of harmful gases is possible in biodiesel usage and its blends. It is concluded that emission reductions and alternative diesel fuel is the output of this investigation.
