Abstract
In the present study, graphene nanobiodiesel was prepared by dispersing of graphene in Simarouba methyl ester (SME) blend with diesel. Dispersion was characterized with ultraviolet–visible (UV–Vis) spectrometry. The performance and emission characteristics of graphene nanobiodiesel were carried out on a single-cylinder, water-cooled, direct injection, four-stroke computerized diesel engine. The characteristics are measured for 3 different dosing levels of graphene nanoparticle. It resulted in improved brake thermal efficiency by 9.14%, reduction in unburnt hydrocarbon (HC) by 15.38%, carbon monoxide (CO) by 42.855 and oxides of nitrogen (NOx) emission by 12.71% with SME2040. Also the addition of graphene nanoparticles has resulted in a significant reduction in the combustion duration and a marginal increase in peak cylinder pressure at all operational loads.
