After the implementation of many measures including the control of the number of motor vehicles, the improvement of oil quality, heating of coal-reforming gas, and the prohibition of stalk burning, why is smog still so severe? In addition to “waiting for windâ€, how can we eliminate or reduce air pollution as soon as possible? Pollutants, diesel vehicles account for 70% of emissions On July 17, 2016, the Ministry of Environmental Protection issued the air quality status of 74 cities in the first half of 2016, including the Beijing-Tianjin-Hebei region, the Yangtze River Delta, the Pearl River Delta region and municipalities, provincial capital cities, and cities with separate cities. Luo Yi, director of the Environmental Monitoring Department of the Ministry of Environmental Protection, said that the overall situation of ambient air quality in 74 cities improved. The concentrations of PM10 and PM2.5 in 74 cities decreased year-on-year, and the average number of good days increased year-on-year. According to the “2016 Annual report of China’s motor vehicle environmental management†issued by the Ministry of Environmental Protection, China has become the world’s largest motor vehicle production and sales country for seven years in a row. By 2015, motor vehicle pollution has become an important source of air pollution in China. The urgency of the pollution prevention and control of motor vehicles has become increasingly prominent due to the important causes of haze and photochemical smog pollution. In 2015, the preliminary accounting for pollutants emitted by motor vehicles in the country was 45,322,000 tons, which was 0.3% less than in 2014, including 5.489 million tons of nitrogen oxides (NOx), 4.302 million tons of hydrocarbons (HC), and 34.611 million carbon monoxide (CO). Tons, particulate matter (PM) 560 thousand tons. Automobiles are the main contributors to the total amount of pollutants emitted by motor vehicles. They emit more than 90% of NOx and PM, and more than 80% of HC and CO. Among them, NOx emitted by diesel vehicles is close to 70% of total vehicle emissions, and PM is over 90%. Eliminating yellow car In 2015, the number of motor vehicles in the country reached 279 million vehicles, an increase of 5.8% from 2014. Among them, the former standard cars that accounted for 1.6% of the total vehicle ownership accounted for more than 30.0% of the total emissions of the four major pollutants of the country, and the emissions of standard cars of the State III and above with 83.5% of the total vehicle ownership. About 35.2% of total vehicle emissions, eliminating yellow-label cars and old cars is imminent. According to the plan for phase-out of yellow-label vehicles and old cars issued by the Ministry of Environmental Protection and the six ministries and commissions, it is expected that by 2017, the nationwide yellow-labeled vehicles will be phased out. The 2015 Government Work Report also clearly stated that the yellow label vehicles registered before the end of 2005 should all be eliminated. However, the amount of pollutants released in 2015 was only 0.3% lower than that in 2014. China has eliminated the use of yellow-labeled vehicles and old cars as the focus of motor vehicles to reduce pollution, but why has the total amount of pollutants dropped only by this point? In this regard, Ding Yan, deputy director of the Ministry of Environmental Protection's motor vehicle emission monitoring center, said that the main reason is that the total number of motor vehicles in China still shows an explosive growth, and the total amount of pollution from motor vehicles is not controlled; in addition, the NOx and PM emissions from trucks across the country are significant. Higher than passenger cars, of which heavy trucks are the main contributors, and the majority of yellow-label vehicles that were eliminated in 2015 were light vehicles, and heavy-duty heavy vehicles were written off after three inspection periods did not come. The elimination of diesel heavy-duty vehicles will increase the effectiveness of emission reduction. Utilize high-cleaning vehicle urea to reduce diesel vehicle emissions In order to implement the Air Pollution Prevention and Control Law and the requirements of government work reports, various regions and relevant departments have formulated working programs and supporting policies that are conducive to pollution prevention and emission reduction of motor vehicles, and strengthened coordination and coordination to regulate and use new vehicles. Comprehensive measures have been taken in the areas of environmental protection management of cars, accelerated phase-out of “Yellow Label Vehiclesâ€, improvement of fuel for vehicles, and supply of urea for vehicles. In terms of vehicle urea, the use of high-purity urea from Carnegies, a "clean core" series, can effectively solve the pollution of diesel vehicles and prevent the formation of haze. At the same time, it does not increase the cost for users. The use of four cars, the user's car costs increased by 2-3 million, the use of vehicle urea fuel consumption of 3% -5%, that is, the consumption of 100L of fuel, the need to consume 3-5L of vehicle urea. The use of urea by the National IV vehicle will also increase the cost. But the fuel will save 3%-5% compared to the original three engines. At present, the urea for vehicles has been the national standard GB 29518-2013, which further regulates the quality of urea for vehicles. The rigorous factory inspection procedures of Kosher ensure the quality of urea used by KUKA Automotive. In the sampling inspections of urea aqueous solution branch offices in the China-China Association of Automobile Industry and Nanjing Bureau of Quality Supervision and other agencies, the sampling sample quality meets the national standards, effectively reducing NOx emissions from diesel vehicle exhaust. While ensuring product quality, Kosher further standardizes the market price system and cracks down counterfeit products on the market, allowing owners to feel comfortable buying. At present, Kosovo is strengthening the construction of outlets throughout the country so that consumers can easily purchase authentic Kosher products and contribute to the protection of the blue sky and the environmental protection of air pollution.

Autumn and winter last year, China's haze was high. Beijing launched the red warning of heavy air pollution twice, not only in the Beijing-Tianjin-Hebei region, but also in areas such as the Northeast and Chengdu-Chongqing, where the smog area has reached 560,000 square kilometers.
