Abstract

The running loss SHED was selected to study the impact of temperature on the running loss emission for light-duty vehicles, and the monthly evolution of vehicle running loss emissions was analyzed in consideration with calculation model, meteorological temperature, and travel patterns. The test results show that the running loss emissions of the vehicle gradually increased with the increase of temperature. In the CLTC cycle conditions, the emission in the low speed phase account for the highest emissions, and is mostly affected by temperature with the highest emission increment due to the accumulation of volatile or permeable fuel vapor before the running loss test caused by long-time hot soak and the fuel tank heating. Based on the meteorological temperature of Tianjin from January to December, the average annual mileage of motor vehicles, the monthly variation coefficient, and the number of motor vehicle, the annual running loss emission is estimated to be approximately 159.54 tons. The monthly running loss emission in January and February are relatively low, then gradually increase and reach the peak at June, stabilize from June to August, and gradually decrease from September to December.
