Effect of Reformulated Gasoline and Methanol on Exhaust Emissions

Speciated Measurements and Calculated Reactivities of Vehicle Exhaust Emissions from Conventional and Reformulated Gasolines

“…Yet, due to a reduction in mass emission rates, a net reactivity benefit could be imputed to the reformulated fuel. This is consistent with results of other published studies involving reformulated gasolines (10,29,30). Slight differences in normalized reactivity were observed among the four vehicle categories tested.…”
