Abstract: The emission inventory and pollution characteristics of on-road vehicles were studied in low temperature areas in winter. Taking Changchun as an example, and based on tests and the technical guide for emission inventory preparation of on-road vehicles, an emission inventory of Changchun was established in 2016. ArcGIS was used to allocate space, and the contribution rate of typical vehicles starting emission was analyzed based on the IVE model. The results showed that the annual emissions of CO, HC, NOx, PM2.5 and PM10 are 137700, 29000, 40900, 2200 and 2400 tons, respectively. Minibuses are the dominant contributors to CO and HC, while heavy-duty trucks are the main sources of NOx and PM10. Meanwhile, the contribution rate during the start-up phase of typical vehicles in Changchun is higher than that in Shanghai.In addition, the emission intensity tends to decrease from the center of city to the outskirts.

Key words: on-road vehicle, low-temperature area in winter, emission inventory, start-up emission, spatial distribution
