Abstract
Propanol isomers are oxygenated fuels that have the potential to reduce the emission of engines. Particulate matter (PM) emissions of gasoline/propanol isomers blends have been comparatively investigated at different blending ratios of propanol isomers (0%, 10%, 20%, 40% and 100%) and EGR (Exhaust Gas Recirculation) rates (0% and 10%). Pure propanol isomers show significantly different emission characteristics compared to the other blends. PM number concentration decreases when EGR is introduced while little variation of PM mass concentration is observed. N-propanol mixtures produce higher PM number concentration than those of iso-propanol mixtures at the same blending ratio caused by their distinctively molecular structures and properties. The present study shows iso-propanol gives better performance as a gasoline additive compared to n-propanol.
