Analysis On The Present Situation Of Vehicle Exhaust Pollution In Huhhot And Its Countermeasures

Nowadays,the pollution resulted from automobile exhausts is getting worse and worse.And air quality has become the primary public concern in recent years.The number of automobile Huhhot is increasing year by year,and the pollution trend is also increased continuously.Therefore,it’s essential to research and analyze the pollution from automobile exhausts in Huhhot.Based on the information acquired from the Huhhot Automobile Exhaust Detecting and Administration Center and the Huhhot Vehicle Management Station,the statistical analysis of Huhhot automobile ownership composition was performed.Various pollutant exhaust factors were calculated systematically by using the China Vehicle Exhausts Model(CVEM),and then all autotomobiles were divided according to vehicle type,fuel type,exhaust standard,pollution level and car brand.Further,the exhaust state and distribution of four different pollutants,CO,HC,NOx and PM,were analyzed.The conclusions are described briefly below.(1)The relationship between the amounnt of vehicle and GDP is linear correlation;as as to the relationslhip between automobile exhausts and the amount of vehicle.(2)Emissions of CO and HC form diminutivc passenger car are higher,and emlissions of NOx and PM from heavy truck are higher.(3)CO emission from gasoline vehicle is higher than that from diesel vehicle;NOx and PM emissions from diesel vehicle are higher than that from gasoline vehicle.(4)The pollutant emission of the low-level-exhaust vehicles have a higher occupancy although their amount is small,especially the PM exhausts.(5)Emissions of CO,HC,NOx and PM from the "Yellow Lable Car" have a higher occupancy.(6)Amongst various vehicle brands,CO emission from German vehicle is the highest;HC,NOx and PM emissions from Chinese vehicle are the highest,and the pollutants emissions from Japanese vehicle are the lowest.Lastly,in order to promote the preventing and administering the pollution control on automobile exhausts,some recommendations were provided in six different fields,such as laws and regulations,administrative measure,scientific technology,real situations,public environmental awareness and dialectical thinking.
