Emission Trends on an Un-modified Research Engine Run with Alcohol and Cashew-Nut Blends

Abstract

The effects of mixing pentanol, a future generation biofuel, with cashew biodiesel on engine emissions in a constant compression ignition engine were studied. Traditionally, cashew nut oil is converted into biodiesel using the transesterification process. Pentanol, an oxygenating component, is used. Three test fuels namely, CB100 (cashew nut biodiesel), CB90P10 (pentanol mixed with cashew nut biodiesel by 10% volume) and C80P20 (pentanol blended with cashew nut biodiesel by 20% volume) were used in the experiment. It was also examined whether it was feasible to use neat biofuel. Experimental tests concluded that those test fuels would not require any modification to engines. Significant reduction in carbon monoxide emissions is seen when 10% and 20% pentanol were added to the biodiesel.
