Abstract
This article discusses the use of biodiesel as an additive for diesohol - a mixture of regular diesel and ethanol. Physical and chemical properties of the diesohol blends were obtained and compared with those of regular diesel. The results showed that, in general, the fuel properties of diesohol with biodiesel as an emulsifier satisfy the requirement of regular diesel, although there is a tendency that increasing fraction of biodiesel results in more carbon residue. Engine performance and emissions of a selected blend (5% vol. biodiesel in the 95:5 diesel:ethanol mixture) were tested on a light-duty truck with a 2.5 L inter-cooled direct injection diesel engine. The results showed that biodiesel-emulsified diesohol produced less maximum power output than regular diesel. No significant difference in the emissions of CO2, CO, and NOx between diesohol and regular diesel was observed. But the use of diesohol resulted in a reduction of particulate matter.
