This year, most parts of the country have experienced frequent haze days. China’s environmental protection pressure has increased unprecedentedly. The State Council has recently made great efforts to reduce the production capacity of steel, cement and non-ferrous metals industries that affect air quality, and strict emission standards. At the same time, the focus of public opinion is also aimed at cars, because with the popularization of automobiles, tail gas emissions, especially the exhaust emissions of commercial vehicles, are increasingly becoming an important factor affecting air quality.
Exhaust emissions are increasingly becoming an important factor affecting air quality. Starting from 2010, the Ministry of Environmental Protection-based management department is set to increase emissions standards for commercial vehicle exhausts in the hope of reducing hydrocarbons, nitrogen oxides, carbon monoxide, and PM. Substances and other substances enter the atmosphere. The specific approach is to replace the National III emission standard engine with the National IV emission standard engine. However, the implementation time has been repeatedly delayed, from January 1, 2011 to January 1, 2012, July 1, 2013, and then to the 2014 unfixed time. In these several postponed periods, the atmospheric environment of Chinese cities has continued to deteriorate, and haze and pm2.5 have become social pain.
According to reports, the main reason for the repeated implementation of the National IV implementation is that the diesel oil monopolized by CNPC and Sinopec cannot meet the national IV emission requirements nationwide. Therefore, the Automobile Industry Association strongly recommends that after the oil products meet the standards, the National IV standard will be fully implemented. This contrasts sharply with the attitude that the Ministry of Environmental Protection strongly urges early implementation. In the end, the relevant state departments adopted the recommendations of the corporate industry.
As a result, the country’s four standards, which are being postponed, are similar to “come as if the wolf is coming†for commercial vehicle production companies. They have not called many times and led some companies to find another way out. As we all know, the higher price of the national four-car than the three-country car is bound to have an impact on sales. According to relevant investigations, some enterprises have illegally used the three national standard cars to disguise themselves as the country’s third-rate car while claiming that they have completed technological transformation. The vehicle obtained the certificate and left a great deal of hidden danger for the full implementation of the future State IV.
Dangerous exhaust <br> <br> national IV emission standard is the national phase IV vehicle emissions standards, vehicle emissions of pollutants mainly hydrocarbons, nitrogen oxygenation, carbon monoxide, PM and other national IV standards that control And reduce the number of pollutants emitted by automobiles to the specified value. China's No. 3 standard has a 30% lower emission limit for exhaust pollutants than No. 2 standard exhaust pollutants, while China's No. 4 standard has been further reduced by 60%.
In response to the delay in the implementation of the National IV standard, the Ministry of Environmental Protection said: “Given that the supply of automotive diesel fuel that currently meets the requirements of the Fourth National Standard is still not in place, it has severely constrained the progress of the implementation of the National IV standard. In order to ensure the implementation of the standard, it is based on the actual fuel supply for vehicles. , decided to sub-model, sub-regional implementation of the four national standards."
The study found that the main source of inhalable particulates in urban air is motor vehicle exhaust emissions, accounting for 29.4% of the total. The main source of carbon dioxide in urban air is also the emissions of motor vehicles, which account for 48.7% of the total. The implementation of the Fourth National Standard will greatly improve air pollution.
It is reported that the National IV emission standard was originally planned to be implemented on January 1, 2011. However, on December 21, 2010, the environmental protection department stated that the implementation time of the diesel standard for the four countries with 3.5 tons or more was postponed for one year, that is, until January 1, 2012. Day implementation. However, due to some reasons, the National IV standard has been postponed again until July 1 this year. However, on the eve of implementation, the Ministry of Environmental Protection has reached an agreement with the Ministry of Industry and Information Technology and the Industry Association on the implementation time of the State Council. The state-wide implementation of the four emission standards for heavy-duty diesel vehicles, which was formally implemented on July 1, will be postponed again.
Prior to this, in May, Director of the Vehicle Pollution Control Center of the Ministry of Environmental Protection, Tang Dagang pointed out to Guosi that on July 1, 2013, it will firmly implement the Phase IV emission standard for heavy vehicles (hereinafter abbreviated as GB17691), without delay. He said that the national IV emission standards will not be postponed. GB17691 has been issued for eight years. According to the timetable established at that time, the country was to implement the five emission standards in 2013 and it is still in the implementation of the national three standards. There are already many preparations for enterprises that are postponed. Therefore, the four emission standards for heavy-duty vehicles should not be postponed any longer, especially in today's very environmental pressures.
Oil the responsibility <br> <br> Obviously, in the process of solving the above problems, the Ministry of Environmental Protection to play the "face" of the main culprits is still oil. Just as the Ministry of Environmental Protection has repeatedly emphasized that heavy-duty vehicle emissions cannot be postponed, the attitude of the industry associations and the Ministry of Industry and Information Technology has been very clear: the vehicle oil must be synchronized.
The industry association believes that in the environment where the quality of diesel oil cannot reach the quality of the three oil products with a sulfur content of 350 ppm or less, the forced promotion of heavy-duty diesel engines will not only fail to meet the limits of exhaust gas pollutants required by the four-phase standard of diesel vehicles. It will cause great damage to the operation of the National IV vehicle. It may even lead to major vehicle failures and even "squeaks," and even cause major problems in the commercial vehicle industry and the upgrading of the logistics industry.
Actually, the reason for each postponement is actually very simple. It is because “the conditions for the implementation of the National IV are not met.†This “two barrels of oil†has always stated that it cannot provide nationwide diesel emissions on a national scale, and it also adds The "reason" of supply of urea solutions for vehicles is also difficult to satisfy.
Due to the unqualified quality of oil products, the China Automobile Industry Association had raised this issue with the two ministries and commissions in May this year. Although the auto companies have already completed the preparations for the State Fourth, the quality of domestic oil products has not only been improved synchronously with the discharge standards. However, the oil quality problem has not only seriously affected the real effect of energy-saving and emission reduction after emission upgrades, but also triggered a wide range of market product quality disputes, caused market confusion, and increased the complexity of the automotive industry, products, and market management. The difficulty has increased the cost and market risk of automotive product launches.
For this reason, the Automobile Industry Association has repeatedly appealed to the National III heavy-duty diesel engines and models already existing in the “Announcement†to recommend a further six-month sales transition after the “National Three-vehicle diesel and automotive urea solutions are in place throughout the country. Period, stop production, sales, and registration after the transition period expires."
Because it is difficult to provide nationwide fully-supplied diesel fuel, and the supply of automotive urea solutions for post-processing is difficult to meet, at the same time, vehicles that have been discharged from China on July 1 of this year will no longer be allowed to report to the Ministry of Industry and Information Technology. In the context of a nationwide delay in the full implementation of the plan, some cities have issued separate local emission policies. For example, Shanghai and Chengdu announced the timing of the implementation of the National IV emissions, among which Shanghai can no longer sell products from July 1 this year. Three diesel vehicles, vehicles that were previously purchased but not on the card can be put up for sale by August 1.
Worry about implementation
“The state has demanded for the country for many years. At present, almost all engine companies claim that they are ready and have already made technical reserves. But what is the actual situation? No conclusion can be drawn without going on the road and not being ruled out. In order to protect the sales, the company has moved illegally.†One person interviewed in the industry said that after all, the country’s four cars are more expensive than the country’s three. In addition, in addition to oil and urea and other external factors, the production consistency of the engine is also The key to implementing the country's four emission standards.
In fact, the phenomenon of corporate fraud occurred at the third national escalation country, resulting in many "false country three" in the market. According to reports, commercial vehicle companies used high-pressure common-rail routes at the time, but they increased the total vehicle cost by 30,000 to 50,000 yuan, which led to a decline in sales volume. This led to the production of lower-cost EGR technology and led to the production of engines. Consistency has dropped dramatically. In addition, at that time, even more tactics to tamper with certifications severely disrupted the market order and further impaired the production consistency of engine products. â€
Industry sources said that after upgrading the engine, due to the addition of a post-processing system, the cost will inevitably increase. Coupled with the impact of oil and urea, some companies may also “send down the road†and then again appear like “fake countryâ€. To this end, the industry suggested that the state should introduce a standard regulatory system, strict inspections of engine companies. At the same time, companies should also shoulder the responsibility of energy-saving emission reduction, establish a corresponding quality assurance system and testing system, and strictly control the process to ensure product consistency.
According to a survey by media reporters, phenomena similar to “false country 3†have emerged. The Pingdingshan City Environmental Protection Bureau and the Public Security Bureau of Henan Province issued a joint document as early as December 24 last year, requesting that, as of July 1, 2013, all gasoline vehicles, dual-purpose fuel vehicles, and single gases that do not meet the requirements of the national environmental protection standard The fuel vehicles shall not be sold and registered in the area of ​​Pingdingshan City, and may not issue environmental protection inspection marks for motor vehicles.
From October 1, 2013, any compression-ignition vehicle that does not meet the requirements of the National IV Environmental Protection Standard shall not be sold and registered in the area of ​​Pingdingshan City, and shall not issue environmental protection inspection marks for motor vehicles. However, according to the reporter, after October 1, some auto brand dealers in Pingdingshan City illegally applied the national fourth-class emission standard automobile qualification certificate to the national three-emission standard automobile.
The person in charge of the local vehicle management department admitted in an interview that the staff couldn’t distinguish the difference between the two types of emission standard cars by naked eyes, and that the seller’s and manufacturer’s partnership’s falsification of the certifications made it more difficult to investigate and handle. It is understood that the local vehicle management office had received SMS messages to report the possession of more than 50 vehicle sets of certificates. According to reports, more than 20 vehicle sets including the Auman and Shaanxi Automobile were certified after October 1. Home. However, according to a survey conducted by the reporter, after October 1, the number of vehicles in the area that use the country's four certificates to enter the country is far more than that.
Industry insiders told reporters that the biggest difference between the two types of cars is that the country’s four countries have more than one car urea tank, which is independently placed on the side of the frame and is easily identifiable. The vehicle management office strictly follows the requirements of the car. There is no unrecognizable situation in the three controls of the license, real vehicle, and announcement.
