The implementation of the Fourth National Standard for Commercial Vehicles can no longer be postponed. Problems such as oil and urea have not been properly resolved at present, but it seems to some people in the industry that they must adhere to standards first. Once the standard is implemented, whether the above problems can be effectively resolved and when it can be solved. A recent government report said that on July 1st, Guo San’s oil products will also be implemented. Then another person in charge of the oil sector said that some regions want to upgrade oil products to the country’s fifth, and they can achieve the oil upgrading technology.
It is near to the implementation of the commercial vehicle national four standard. Whether the supplier and the automaker are ready for technical upgrading on the diesel engine, or the local supplier is still blank on the core technology, and the purchase of the main components of the auto factory still comes from Foreign investment and joint ventures. The long-awaited National IV standard has finally been implemented. However, there are many problems to be faced, but it is true, as industry insiders say, that we must adhere to standards first, and only if we have the direction, requirements, and constantly improving policies and regulations. The upgrading of diesel technology and related supporting measures can be realized and improved.
Director of the Vehicle Sewage Monitoring Center of the Ministry of Environmental Protection Tang Outline: Heavy-duty diesel will not postpone the delay of light firewood may be postponed: heavy-duty diesel engines should not be postponed, light diesel engines may be delayed
Heavy-duty diesel engines should not be postponed. Light-duty diesel engines may be delayed. Heavy-duty diesel engines, after SCR treatment, are more resistant to oil, and now reportedly can withstand 350PPM diesel. Therefore, even after July 2013, if there is no 50PPM of oil, the heavy duty diesel locomotive that uses the SCR after-treatment can be used without problems.
In addition, there are some engines that take the DOC path and cannot tolerate 350PPM of oil, and it cannot be guaranteed that 350ppm of diesel can be used. However, the mainstream engines are now SCR post-processing technologies. Therefore, the implementation of the National IV standard on July 1, 2013 is not a problem.
In addition, at the end of 2012, a meeting convened by the China Internal Combustion Engine Industry Association also shouted a slogan “National IV emissions, we are ready.†At that time, the domestic mainstream automobile companies and engine companies all attended the meeting. Everyone said that there was no problem with product preparation and production preparation.
However, the current problem is the light diesel engine. Because the SCR's post-processing device is relatively large, it is not very easy to install for light vehicles. In addition, from the experiments conducted by various engine companies, the heavy-duty diesel engine basically used 350 ppm of diesel, while the light-duty diesel engine used 50 ppm of diesel. If it is impossible to supply 50 PPM of diesel fuel on July 1, 2013, these light diesel engines will have to re-prepare products and re-test 350 PPM diesel, all of which will take time. Therefore, the implementation date of the fourth emission of light diesel engine may be postponed.
In addition, according to the requirements of the emission regulations, the diesel fuel of the National IV should be provided after July 1st of the previous year, that is, the diesel fuel below 50PPM. However, now most of the country cannot provide it. At present, the state stipulates that the emission standard for diesel fuel for vehicles is 350 PPM or less, and the emission standard for ordinary diesel fuel is 2,000 PPM. However, in fact, there are many car petrol stations, such as gas stations on highways. Obviously, they can only refuel cars. They can't refuel cars, but they don't supply car diesel, but they supply regular diesel. In this case, the state should strictly regulate and enforce the law. For gas stations that provide fuel for cars, especially gas stations on high-speed roads, they can only provide vehicle diesel. Otherwise, there is no way for these illegal gas stations.
Fu Chengyu, Chairman of Sinopec Corp.: While improving the quality of oil products, it is also necessary to improve the technical level of the engine.
In the past, we did not say that we could not do it technically or in terms of capabilities. Instead, our local governments chose their own oil standards.
Several governors are now looking for me, stating that they would like to upgrade their oil products from the province to the fifth in the year and ask if I can guarantee it. I said I can give you protection at any time. In my opinion, oil upgrading technology can be achieved completely.
The refined oil mentioned in Country V not only reduces the emission of sulfur, but also consumes more energy to improve the quality of oil products. We need to do a good job in both areas. We must improve the technical level of the engine while improving the quality of the oil. If the car engine fails to meet the standards, eats “fine grain,†or if the emissions do not meet the standards, it will not reach the standard. To environmental effects.
In the protection of the ecological environment, I believe that the first priority is to enact legislation to raise environmental standards. Second, all industrial enterprises must assume certain responsibilities for environmental protection because we are also consuming society while producing and creating material wealth. Resources, manufacturing of various pollutants.
At the same time, in addition to legislation, pollution control is to adopt an energy price system that complies with the law of market prices. Now that the government has made adjustments in various aspects, we are confident that we will advance in accordance with the laws of the market in a short period of time.
In addition, China is currently undergoing a new round of industrialization. Industrialization means that a large amount of energy is consumed. According to the past development model, it is also a serious stage of pollution. Therefore, we cannot take the old road of industrialization in the West.
Moreover, if we break away from climate change and environmental protection, it is difficult to find the right direction when it comes to energy security alone. At present, our energy conversion efficiency is relatively low, and energy consumption is also very large. Energy allocation is related to overall energy planning. Our resource allocation is very unreasonable. For example, coal is transported from a coal production site to a long distance, and then electricity is generated and transported back. This results in wasted energy. Second, how can the energy efficiency in the production area be improved? . Whether it is oil production, coal production, or electricity production, our past industry standards in this area are relatively low and cannot meet the standards of Western countries.
Academician of the Chinese Academy of Engineering and Director of the 711 Institute of China Shipbuilding Industry Corporation, Jin Donghan: Sticking to Standards First
The attitude toward emission upgrades is to uphold standards first. Kim Dong-hwan said that European countries are putting forward standards and then trying their best to achieve them. The same is true for us now.
Dong Yang, executive vice president and secretary-general of the China Association of Automobile Manufacturers: The implementation of the country’s four is facing many difficulties, but the implementation of the National IV standard will also face major problems.
Upgrading to the Fourth National Standard, the denitrification agent has not landed at all. Although the enterprise says that it can produce, there is a long distance from the realization of the production process to the use, and there is a lack of implementation measures. If after the implementation of the national four diesel, denitrification agent supply shortage, how to do damage to the car, consumers tell us how to do, law enforcement agencies on the way to deduct the car how to do?
However, in terms of the automotive industry, there are major problems in postponing the implementation of the National IV standard because we are ready. If we cannot upgrade to the "National IV" standard, it will affect technological progress and will also affect the enthusiasm of parts suppliers.
In addition, in addition to PetroChina Sinopec, there are more than 20% privately-owned oil refining and fuel oil supplies, as well as imports. In this case, how to meet the standards of fuel oil is a major regulatory issue. And it is unlikely that the government will introduce a policy to subsidize the country's four standard diesel, but it will allow the national standard diesel to increase its price.
