Chengdu Implements Vehicle IV Standard on July 1st

From July 1 onwards, new vehicles entering the market must first pass through China IV customs Chengdu will take various measures to prevent motor vehicle pollution. On July 1 this year, Chengdu will implement the national IV emission standards of motor vehicles in accordance with the national unified plan. At the on-site verification and training meeting for the quality update of pollution investigations in Chengdu held yesterday, the relevant person in charge of the Chengdu Municipal Environmental Protection Bureau talked about plans to increase total emission reductions this year. He said that vehicle pollution is an important issue for nitrogen oxides. Source, the next step will take a variety of measures to promote pollution prevention and control of motor vehicles, as well as denitrification of power plants, denitrification of cement plants and the elimination of outdated production capacity of nitrogen-related work.

Respirable particulates become the "culprit" of air pollution

During the “Twelfth Five-Year Plan” period, the country’s major pollutant emission reduction targets have been increased on the basis of sulfur dioxide and chemical oxygen demand, and ammonia nitrogen and nitrogen oxides have been added. Since Sichuan had previously implemented a total reduction in the total amount of ammonia nitrogen, the reduction in nitrogen oxides has become a pressure factor for the environmental protection agencies.

Regarding how to promote nitrogen oxide emission reduction, the responsible person of the Municipal Environmental Protection Bureau stated that the total emission reduction of nitrogen oxides will be strengthened through measures such as denitrification in power plants, denitrification in cement plants, elimination of obsolete production capacity of nitrogen-related products, and pollution control of motor vehicles. According to monitoring by the environmental protection agency, the “culprit” of air pollution in Chengdu has changed from sulphur dioxide and nitrogen dioxide to respirable particulate matter, which is closely related to motor vehicle pollution. In addition, motor vehicle exhausts also produce highly polluting substances such as hydrocarbons, nitrogen oxides, and carbon monoxide.

Strengthen the road inspection two mobile monitoring vehicles will be on the road according to the national unified deployment, Chengdu will implement the national vehicle IV emission standards on July 1 this year, the new car entering the market must meet the national IV standard.

According to public information, some cities in China have previously implemented the National IV standard. In 2008, Chengdu implemented the National III standard, but due to the large number of motor vehicles that used the country's standard II oil at the time, automobile exhaust pollution was still very serious. After the implementation of the National IV standard, the pollution control of motor vehicles will be promoted from various aspects, such as the emission allowances and the quality of oil products.

In addition to motor vehicle pollution, oil and gas volatilization at gas stations is also an important source of pollution. In the future, gas and gas recovery and treatment at gas stations will be strengthened. In addition, Chengdu will also strengthen road inspections this year. The two mobile monitoring vehicles purchased by the Municipal Environmental Protection Bureau will be on the road to carry out monitoring.
