“When China implements the Euro III standard, how much can air quality be improved?†Just as all parties were busy with Euro III, one person in the auto industry asked such a question. What is the “contribution rate†of Euro III to improve the atmosphere? “In recent years, the number of motor vehicles in Beijing has been continuously increasing, but the number of days when we can see the blue sky has become more and more. What are the reasons?†A question from a car environmental expert confuses reporters. After seeing the reporter’s doubts, the expert asked himself: “In the past, Beijing was mainly smoke-type pollution, and now the boilers have been transformed into natural gas, and the situation has greatly improved. It was not successful." Then he continued to ask: "If you watch the air pollution index broadcast by Beijing TV every day, you will find that the primary pollutants in Beijing's atmosphere are almost all respirable particulates all year round, but data from countries around the world show that Only 7% to 10% of the inhalable particulates in the air are emitted by cars. How is the other 90% of inhalable particulate matter produced? Is the car the main source of atmospheric pollution in Beijing?†Absolutely not. “Generally speaking, every time the country raises its emission standards, it will be able to reduce vehicle exhaust emissions. It is a good thing that Beijing will implement Euro III next year.†The expert suggested that according to international experience, what kind of pollution control methods will be adopted by countries and regions depends on The share of the atmosphere. "From the current situation, the main target of Beijing's air pollution control should be to find out the origin of respirable particulate matter. Only by drastically reducing the amount of respirable particulate matter can air quality be significantly improved." Only from the perspective of China's implementation of emission standards, "Only the implementation of Euro III and OBD (vehicle diagnostic system) at the same time will play a relatively large role in reducing air pollution." Engineers who have been working on the issue of exhaust emissions from automobiles have proposed that they work by controlling vehicle emissions to control atmospheric pollution. The focus should be on the management of the exhaust gas in the vehicle. “China should strengthen the establishment of the I/M system (detection/maintenance) because 60% of the pollutants in automotive emissions come from cars that are not well-maintained by the vehicle's emission system, which accounts for 20% of the total number of vehicles in use. According to the current situation in China, environmental protection experts analyzed, “In 2000, the national implementation of the national I standard, the car fitted with catalytic devices, air pollutants reduced by 80% to 90%, the implementation of the State II standards can reduce the absolute amount of pollution There are few things, and the implementation country can reduce even less, and based on the implementation of the country II standard, the implementation of the country III standard can be reduced by 20% to 30%, but the absolute amount can only drop a few percentage points. Can oil guarantee Euro III requirements? "China Motorsport should appeal to the issue of automobile oil." On July 1st, after the State Environmental Protection Administration held a press conference to implement the National II Standard, the State Environmental Protection Bureau deputy director Wang Jichen raised this hope to the newspaper. . At this meeting, the relevant person in charge of the State Environmental Protection Administration once stated that at present, the oil in the market basically meets the requirements of State II, but the implementation of Euro III standards, but also the introduction of new vehicle fuel oil. In order to cooperate with Beijing to implement the Euro III standard, Sinopec will supply fuels meeting the Euro III standard specifically to Beijing in the next year, but this will not solve the fundamental problem. Auto fuel is still a heart disease of the State Environmental Protection Administration. “The implementation of Euro III, oil products is the biggest obstacle. The long-distance car is a big problem. Sinopec, PetroChina only to Beijing to meet the EU III oil standards, which means that Beijing's cars can not out of the city, because the oil in other areas The Euro III car has damage.†A car company's technical engineer has expressed concern for consumers. “Even if Sinopec supplies oil to the country in 2008, can the gas stations provide good oil for a long time?†said one expert in the automobile industry. “The State Administration of Quality Supervision has recently conducted a survey on oil products and the results show that it meets the requirements of the State II standard automobile industry. Only 67% of the fuel used is a qualified product. Vehicle fuels that meet the National II standards do not meet the 100% pass rate. How can gas stations guarantee the supply of vehicle fuel that meets Euro III standards for many years?†It is very likely that the quality of gasoline will not meet the requirements and the Euro III standard will be difficult to achieve. “If your car does not reach the Euro III standard, will the annual inspection be a problem in the future? If you want to pass this Euro III standard inspection , Is it necessary to spend some money to live? At least it has to adjust the exhaust, if you adjust the exhaust, it will not be free? Therefore, according to the current quality of gasoline, hard on the EU III standard, may bring to consumers Risk and economic burden.†Regardless of whether it is from environmental protection or from the standpoint of safeguarding consumer interests, the country has the responsibility to ensure that consumers can use “safety oil†after purchasing Euro III vehicles. It is understood that the State Environmental Protection Administration must coordinate with the relevant departments and related petrochemical groups to formulate China's low-sulfur automotive fuel plan to solve the vehicle fuel problem that matches the Euro III standard. However, the State Environmental Protection Administration is not the competent department for oil production. Can the fuel problem be truly solved? Consumers believe that “difficulties.†Experts who understand the formulation of the National III standard have revealed that the National III standard has not been introduced for a long time. One of the important reasons is that the provisions for the oil products in the State III standard have not yet been determined. Can companies introduce Euro III cars? In the face of the implementation of the Euro III standard throughout the country in 2008, and Beijing's implementation in advance next year, will companies be able to launch vehicles that meet Euro III standards? The technicians of Zhengzhou Nissan firmly stated that at the beginning of next year, Zhengzhou Nissan will launch a car that meets Euro III standards. “We only need to introduce foreign technology. But China’s autos will eventually implement the Euro III standard. State III standards, and the current state III standard has not yet been promulgated, Beijing will be implemented next year, and start OBD at the same time, to the company to prepare a little time. " Zhengzhou Nissan's technical staff put it lightly put forward all automotive companies in the implementation of Euro III standards Problems encountered in the process. Beijing Environmental Protection Bureau has already decided that Euro III and OBD will be implemented at the same time. And propose three kinds of schemes that implement Europe III and OBD: The first one, both start at the same time; The second, implement Europe III, and install OBD hardware does not install software; The third, implement Europe III, but postpone installing OBD. Beijing Municipal Environmental Protection Bureau is currently discussing which plan to adopt. They believe that the second option is most likely to be implemented, but companies are opposed to doing so. "This will increase the cost of the company and restart it for re-commissioning." In addition, the company believes that "some of the accessories in the OBD, such as sensors, will work when the car is in normal use, if it is installed but does not allow it to operate." The responsibility of the company is also not clear.†In addition, some companies have proposed that although the “Automotive Industry Development Policy†has been announced, the problems posed by the multi-headed management of automobiles still exist. In terms of the implementation time of emission standards, Article 71 of the "Automobile Industry Development Policy" stipulates that "the relevant state departments shall formulate and promulgate automobile emission standards uniformly and divide them into current standards and expected standards according to the national conditions. Each province, autonomous region, and municipality directly under the central government The People's Government chooses to implement the current or expected standards according to local conditions. If the expected standard is selected as the current standard, the implementation date shall be announced at least one year in advance." If Beijing implements Euro III standards on July 1 next year, as early as July of this year. On the 1st, the implementation time should be formally announced, but so far, the implementation date has not been formally announced, and there are still few conditions for implementing the Euro III standard. The State Environmental Protection Administration stated at the press conference held on July 1 that the National III standard has been formulated and is awaiting approval. In addition, “Our country still does not have OBD standard at present, the domestic can't do OBD experiment at present, and Beijing will implement Euro III standard and OBD next year. †Car enterprise feels very difficult, but now can only overcome these problems by one's own efforts. . Chinese enterprises are currently drawing on the European-European III standard and are actively developing and designing products. Although companies have stated that they can launch Euro III cars in a timely manner, it is understood that the content of the National III Standard and the Euro III Standard is almost the same, but the enterprise still hopes that the relevant authorities will introduce the National III Standard as soon as possible.
