· Why is it difficult to cure diesel exhaust emissions?

In response to many problems in diesel vehicle exhaust emissions, CCTV has tracked reports that the Ministry of Environmental Protection and other national ministries have issued documents and conducted random inspections. As early as June last year, the General Office of the State Council has issued "2014". The 2015-2015 Energy Conservation and Emission Reduction Low Carbon Development Action Plan (hereinafter referred to as the “Program”) will increase the emission reduction of motor vehicles. Among them, the "Program" pointed out that by the end of 2014, the country will supply four standard vehicle diesels in the country, and eliminate 6 million yellow-label vehicles and old vehicles; by the end of 2015, Beijing-Tianjin-Hebei, Yangtze River Delta, Pearl River Delta, etc. The key cities in the region will supply the country's five standard vehicle gasoline and diesel.
However, at present, there are still many diesel vehicles that are not up to standard on the road. Why is the problem of exhaust emissions fraud not being effectively managed?
Yue Xin, director of the Automotive Fuel Emissions Laboratory of the Chinese Academy of Environmental Sciences, believes that the main punishment is small, the environmental protection department has weak supervision ability, and the technical ability is not enough, and the testing equipment is not perfect. According to Yue Xin, the current environmental protection department is tense and there are not enough people to check so many cars.
In the view of Li Wei, deputy director of China Automotive Research Institute's vehicle emissions department, the punishment mechanism for enterprises after the spot check has not really been implemented. "A lot of random inspections are not only rectified within a time limit, but also temporarily canceled the announcement. For enterprises, the deterrent effect is not enough." Li Wei said.
An industry insider who did not want to be named said that it is understood that the Ministry of Environmental Protection conducts an investigation every year on the issue of diesel vehicle emission fraud, and also found problems, but specifically which companies are in violation of regulations, what companies have adopted for illegal vehicles sold out Effective remedies, what penalties these companies have received, are not known.
According to Articles 53 and 54 of the Environmental Protection Law, the industry has suggested that the Ministry of Environmental Protection should disclose the information for each investigation.
The public information also showed that in March 2014, the Ministry of Environmental Protection conducted environmental protection key component verification for the national three and four diesel vehicles produced by 16 companies in Beijing, Tianjin and Hebei, and found that the pass rate was only 32%.
In this regard, the rule of law weekend sent a letter to the Ministry of Environmental Protection, asked 16 companies specifically including which companies, what kind of punishment, but as of the time of publication, has not yet received a reply.
Li Kunsheng, director of the Motor Vehicle Emissions Management Office of the Beijing Municipal Environmental Protection Bureau, said that this situation is not very effective by the environmental check and punishment of entering the Jingkou intersection. Only when these vehicles are scrapped can the problem be solved.
However, Zhang Hua (pseudonym), who has been engaged in truck transportation for more than ten years, believes that for those diesel vehicles that have not yet reached the end of their retirement years, this time they are in a very embarrassing situation, and the owners are not willing to put the diesel vehicles that have not reached the end of life. Eliminate and spend money to buy a new car.
“Can a diesel vehicle that does not meet the emission standards be converted into a vehicle that meets emission standards?” asked the rule of law weekend reporter.
"Because the current diesel vehicle line technology is more complicated, modification is a very troublesome thing, and the cost is not low." Zhang Hua said.
However, Wang Canfa, director of the Institute of Environmental Resources Law at the School of Civil and Commercial Economics of the China University of Political Science and Law, seems to be able to improve with the implementation of the newly revised Air Pollution Prevention and Control Law on January 1 next year.
"The previous air pollution prevention and control law falsified the automobile emissions, including the falsification of the test, the punishment was very light, and did not have the deterrent effect. The new air pollution prevention and control law made stricter regulations on this point. I believe in After the implementation of January 1 next year, as long as the law enforcement is strict, it will have a certain reversal effect on car emissions fraud." Wang Canfa said.
