New national standard implemented in May, Shanghai will increase monitoring of diesel vehicles

　　On the same day, Shanghai has developed a legal search and inspection of diesel vehicle emissions related to diesel vehicles by the situation monitoring unit and the public security traffic police unit.

　　The Shanghai Municipal Bureau of Ecological Situations revealed that starting from May 1, this year, the "Limits and Measurement Techniques for Pollutant Emissions from Diesel Vehicles" will be officially implemented, and the standards for emissions from diesel vehicles will be significantly tightened. According to the new standards, Shanghai's large one-sided diesel vehicles probably exceed the standards and will face punishment.

　　Because, according to the new standards, Shanghai's large one-sided diesel cars probably exceed the standard and will face punishment. To this end, the situation monitoring part turns on the preheating mode, prompting the diesel car company to secretly do vehicle maintenance to ensure that the exhaust emissions reach the new standard request.

　　Based on decision-making, this year, Shanghai must implement the national "Three-year Action Decision to Win the Guardian of the Blue Sky" and "Shanghai Clean Atmosphere Action Decision", and deepen special actions such as coal reduction, firewood control, nitrification reduction and weight reduction. Strengthen the prevention and control of fouling of flexible vehicles, ships and off-road mobile machines. Implement the national standard of new cars in advance; increase the spot checks and laws of diesel vehicles on road inspection and telemetry, and promote the management of substandard vehicles. At the same time, we should quickly study the detailed policies of the total number of severe diesel trucks and suburban pai. We will work out a plan for the mediation of transportation arrangements in Shanghai and the Yangtze River Delta to promote the proportion of water-to-water transfers and water-to-iron transfers. And as soon as possible to study the establishment of high-emission off-road moving machine prohibited areas, strengthen monitoring laws, and accelerate the elimination of high-polluted machines.

　　The Shanghai Ecological Situation Bureau revealed that mobile pollution source management has become one of the tense issues in Shanghai's atmospheric management. At present, Shanghai Mobile Source's contribution rate to PM2.5 accounts for about 1/3. Among them, the pollution emission of flexible vehicles accounts for about half of mobile sources. Tighter emission limits for diesel vehicles will help reduce exhaust emissions.
