Some issues of road emission for passenger cars and light duty vehicles sector in the aspects of environmental protection

The benefits of electrified powertrains for light-duty vehicles are well understood, however sufficient published information is not available on the benefits of advanced powertrains on the various types of medium and heavy duty vehicles. Quantifying the benefits of powertrain electrification will help fleet operators understand the advantages or limitations in adopting electrified powertrains in their truck fleets. Trucks vary in size and shape, as they are designed for specific applications. It is necessary to model each kind of truck separately to understand what kind of powertrain architecture will be feasible for their daily operations. This paper examines 11 types of vehicles and 5 powertrain technology choices to quantify the fuel saving potential of each design choice. This study uses the regulatory cycles proposed by the US Environmental Protection Agency (EPA) for measuring fuel consumption.

Road Emission

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.
