Study on On-Road Emission Characteristics of Gasoline Passenger Cars Fueled with Butanol-Gasoline Blends for Environmental Protection

Abstract:

An experimental investigation was conducted using PEMS(portable emissions measurement system) to compare on-road emission characteristics of passenger cars fueled with several butanol-gasoline blends including a 10% and 20% butanol-gasoline blend (by volume) to that of gasoline. It was found that the higher the proportion of butanol blends in gasoline is the lower the emissions of CO, CO2, unburned hydrocarbons exhibited, while the emission level of NOx is just the opposite. Meanwhile, the emissions of gasoline passenger cars are related with both the traffic conditions and the vehicle speed. Thus, using butanol-gasoline blend fuel as well as improving the traffic conditions is important to lower the emissions of cars so that they are useful to environmental protection to a certain degree.
