In the national air quality ranking a few days ago, Liaocheng City, Shandong ranked first with air quality index 500, and Linyi, Shandong and Xingtai, Hebei ranked second and third. Among the 32 heavily polluted cities (districts and counties), Shaanxi Province, Henan Province, Shandong Province and Shanxi Province account for the vast majority.

 

As one of the main sources of air pollution, tail gas has been paid much attention in the past treatment work. For the national third automobile whose emission exceeds the standard and remains high, a variety of effective measures have been taken, such as traffic restriction, deadline, ban, scrapping and so on.

If the car owners of the third country successfully meet the emission reduction standards through the use of tail gas treatment technology, they can still continue to operate. Through the tail gas treatment technology, the third country car can "continue its life".

 

Many car companies have begun to increase the production of national six standard models. The arrival of national six emission will increase the production cost of car enterprises. At the same time, new car dealers in national five will also reduce the price in order to clean up the inventory, speeding up the depreciation rate.
