[Truck Home Original] Entering the 39th century, the weather is getting colder and the air quality problem is becoming more and more serious. "Gray sky" is reappeared in many places, and the visibility is extremely low. As the largest source of pollution and the largest source of mobile pollution except steel and chemical enterprises, the exhaust supervision of motor vehicles is particularly strict in winter.
In the national air quality rankings a few days ago, Shandong Liaocheng City ranked first with air quality index 500, Shandong Linyi, Hebei Xingtai ranked second and third. Among the 32 cities (districts and counties) with severe pollution, Shaanxi Province, Henan Province, Shandong Province and Shanxi Province account for the vast majority.
exhaust gas, as one of the main sources of air pollution, has been highly valued in its past governance work. A variety of effective measures have been taken for the National III vehicles, which have exceeded the standard of emissions and have remained high, including restriction on travel, deadlines, banning on travel, scrapping, etc.
National III vehicle that does not meet the standards is indeed a major source of pollution. The pollutant emissions of a National III diesel vehicle are equivalent to 50-80 times that of a National V sedan. However, should National III vehicle be sentenced to "death penalty". Can some National III vehicles that exceed the standards for emissions exceeding the standards before their service life be saved?
The answer is yes. Many provinces do not kill themselves in one shot in the governance of diesel vehicles that exceed the standard. Many diesel vehicles that exceed the standard emissions are still allowed to go on the road after the emission reduction is met, which also reflects the humanization and concretization of the governance process.
National III car owners who successfully reduce emissions through exhaust treatment technology can still continue to operate. Through exhaust treatment technology, National III car can "spend their lives".
But it is worth noting that real-time monitoring equipment must be installed to install DFP and must be cleaned up in time to avoid safety hazards caused by blockage of exhaust system.
