Embodiment Construction

[0023] The present invention will be further described below in conjunction with embodiment. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0024] Such as figure 1 As shown, a method for estimating the impact of future motor vehicle structure adjustment on the traffic emission source inventory includes the following steps: (1) According to the Traffic Yearbook of Jiangsu Province, collect and sort out 13 cities in the province (Nanjing, Suzhou, Wuxi, Changzhou, Zhenjiang , Yangzhou, Taizhou, Nantong, Yancheng, Lianyungang, Huai'an, Suqian, Xuzhou) of motor vehicles (light vehicles, heavy vehicles, motorcycles) and their average mileage, so as to estimate the driving ratio of motor vehicles in different cities. Taking Nanjing and Xuzhou as examples ( figure 2 ), it can be seen that the proportion of light vehicles in Nanjing is as high as 77%, w...

Abstract

The invention discloses an estimation method for an influence of future motor vehicle structure adjustment on a traffic emission source list. Based on a traffic yearbook, and according to actual motorvehicle population and driving mileage of a city, a driving ratio of light and heavy vehicles to motorcycles in the city is estimated; according to collected and sorted literatures and data, the Reidvapor pressures of fuel and the sulfur content of the fuel in various regions are adjusted; by utilizing an MICAPS meteorological database, meteorological fields (temperature, humidity, cloud cover,terrain height and the like) of an estimated region are obtained, related environment parameters required by a model are adjusted, and motor vehicle emission factors of various regions and motor vehicle emission factors in a scene of different substitutions of future electric vehicles are estimated by utilizing the MOBILE model; and finally according to the estimated emission factors, and in combination with the motor vehicle population and the average driving mileage of the city, the influence of the future motor vehicle structure adjustment on the traffic emission source list is estimated.

Description

technical field [0001] The invention belongs to the technical field of traffic emissions, and in particular relates to a method for estimating the impact of future motor vehicle structure adjustments on the list of traffic emission sources. Background technique [0002] With the rapid development of China's economy and the rapid advancement of urbanization, the number of motor vehicles is increasing day by day. Especially in the economically developed Yangtze River Delta region, motor vehicles in some cities are almost saturated, and motor vehicle exhaust emissions account for the total air pollution. The proportion of air pollution is also increasing, exacerbating the further deterioration of air quality. Although motor vehicles are equipped with exhaust gas purification devices at present, most of them have single functions and are expensive, and cannot fundamentally solve the exhaust emission problem. At present, gasoline and diesel are still the main fuels for most moto...
