The most stringent environmental standards of motor vehicles

According to news BEIJING, China 2 environment officials in Beijing said it would speed up the implementation of the development of diesel truck pollution control campaign of action programs, to establish the most stringent motor vehicle implement "full anti-full-controlled" environment monitoring system, promoting urban and regional ambient air quality improved significantly.

Recently, the Department of Ecology Environment issued "China's annual automobile Environmental Management (2018)", published last year, the management of the national vehicle environment. "Annual Report" shows that China has become the world's automobile production and sales for nine consecutive years superpower. Last year, the national vehicle fleet amounted to 310 million, an increase of 5.1?motor vehicle pollution has become an important source of air pollution in China. To this end, the ecological environment of atmospheric Management Division Head of the Ministry of Environment said it would speed up the development of action plans to reduce the amount of diesel emissions, and to establish the most stringent motor vehicle "full anti-full-controlled" environment monitoring system.

According to the "Annual Report" statistics, the car has dominated our vehicle. Specifically, last year, car ownership in China reached 217 million, an increase of 11.8?new energy vehicle population reached 1.53 million, an increase of 50.9?Environmental Management Division of the Ministry of Ecology Environment Atmospheric official said that with the rapid increase in vehicle population, some Chinese urban air is beginning to show a composite vehicle exhaust soot and pollution characteristics of a direct impact on public health.

Data show that, in recent years, the overall air quality improved Jingjinji area, but nitrogen dioxide (NO2) is far lower than the average concentration decline other contaminants. During heavy pollution weather, nitrate PM2.5 component is the largest and fastest growing proportion of components. Beijing, Tianjin, Shanghai and other 15 cities Atmospheric PM2.5 source apportionment work results show that local emission sources in mobile source contribution to PM2.5 concentration range of 13.5 to 52.1 percent. Beijing, for example, in May this year, the Beijing Municipal Environmental Protection Bureau released a new version PM2.5 source apportionment latest research results. Compared to the first version of the 2014 Beijing source apportionment data released in recent years, Beijing PM2.5 source structure has undergone significant changes. At present, the Beijing local emission sources in all major source of contribution to the absolute concentration of PM2.5 overall decreased, coal-fired source of the most significant decline, the proportion of mobile sources of pollution such as motor vehicle is increased to 45?which is the last round of analytical results (accounting for 31.1?of 1.4 times.

In the increasingly serious problem of motor vehicle pollution, reduce emissions of diesel vehicles, large trucks and other heavy vehicles are regarded as the key to solving the problem. Data show that car ownership accounted for 7.8?f the diesel truck emissions of NOx and 57.3?f the 77.8?f PM, is the most important motor vehicle pollution control. To this end, the atmosphere in charge of Environment Management Department, said the Ministry of Environment will accelerate the development of eco-implemented campaign of diesel truck pollution control action program to establish the most stringent motor vehicle implement "full anti-full-controlled" environment monitoring system, the implementation of clean diesel vehicles, clean diesel , clean transportation and clean fuel of the four operations, and ensure that rail freight was significantly improved, diesel and urea quality improved significantly, diesel emissions compliance rate improved significantly, significantly reduced pollutant emissions and promote urban and regional air quality improved significantly.
