Editor's note: Starting on July 1, the National IV emission standards will be implemented. What impact will the new emission standards bring to automakers and government procurement markets? What are the issues that need to be solved to implement the new standard? The reporter interviewed related experts and vendors on the above issues and asked them to answer the reader's questions.

Due to technological bottlenecks and other reasons, 90% of commercial vehicles currently sold nationwide cannot yet meet the National IV standard.

The State IV finally came. As early as in 2009, there was news that China will fully implement the national IV emission standards in 2010, and the new standard has finally been implemented. Automobiles are recognized as large polluters. The benefits of raising emission standards for environmental protection are obvious. However, the impact of increased emission standards on oil prices, vehicle prices, and manufacturers' production and operations also deserves our consideration and attention.

Passenger cars basically reach new standards

“Actually, this has basically no effect on passenger car companies. The sales of passenger cars have basically reached the national IV standard, and Beijing began to implement the national IV standards as early as before the 2008 Olympic Games.” Yayuncun A dealer in the auto market told reporters. It is understood that the cities that have entered the National Phase IV in advance are Beijing, Shanghai, Nanjing and Guangzhou. Emissions increase standards have little effect on these cities.

In addition to the above-mentioned major cities, some advanced regions have already entered the national IV stage in advance. As early as July 2010, the Traffic Management Bureau of the Public Security Bureau of Guangdong Province issued a document requesting the implementation of the fourth phase of the national machine in the Pearl River Delta including Guangzhou, Shenzhen, Zhuhai, Foshan, Jiangmen, Huizhou, Zhaoqing, Zhongshan and Dongguan. Emission standards for pollutants from motor vehicles. According to the relevant person in charge, at present, in the Pearl River Delta region, motor vehicles must meet the national IV standards before they can be branded. It is expected that the emissions of light-duty bicycles will be reduced by about 50%, that of heavy-duty vehicles will be reduced by about 30%, and particulate emissions will be reduced. More than 80% of total pollutant emissions from the entire Pearl River Delta will therefore be reduced by 15% to 20%. It can be seen that the escalator IV is not a problem for the general city and passenger car companies. So, can escalation country IV be smooth?

Oil issues need to be solved urgently

It is understood that the full implementation of the National IV emission standards, the difficulties are mainly concentrated in oil products and commercial vehicle companies.

Du Fangci, deputy secretary-general of the Automobile Industry Association, said that the biggest problem in fully implementing the national IV emission standards is not the technical problem of fuel engines, but the oil products in the market. In order to promote the national IV emission standards on a large scale across the country, the current priority is to raise oil from the market to meet the requirements for the use of the National IV engine rather than requiring the engine manufacturers to raise the engine again and again. Fuel performance. Otherwise, no matter how advocating national IV emission standards, it is just an empty talk. At present, there are also many users on the Internet to discuss the issue of the fuel of the National IV standard. There are many netizens asking “What can I do if I don’t add oil to China IV?” and “Is the national IV vehicle capable of adding Canada's oil?”.

Regarding oil products, Vice Minister of Environmental Protection Zhang Lijun once said in a question to the Fourth Session of the 11th National People's Congress that it will speed up the implementation of the “National IV” emission standard for motor vehicles and accelerate the upgrading of refinery oil product quality. We will implement the implementation of "National IV Oil" as soon as possible throughout the country. However, judging from the current situation, especially in less developed areas, the quality of oil products is still out of line with the new standards.

Larger impact on commercial vehicle companies

Another impact of the IV national emission standards is mainly concentrated on commercial vehicle companies. Compared with the National III environmental protection standard, the National IV standard requires that the emission limit be reduced by approximately 50% on the former basis. For this reason, the electronically controlled fuel injection system of the engine needs to be re-matched and the catalytic converter formula is recalibrated to add precious metal elements. Electronically controlled fuel injection has higher control accuracy. "This may be quite difficult for some companies," an automotive technologist told reporters. According to industry sources, due to technical bottlenecks and other reasons, 90% of commercial vehicles currently sold nationwide cannot yet meet the National IV standard. Tan Xiuqing, vice president of Shandong Heavy Industry Group Co., Ltd., told reporters: “For commercial vehicle companies, technology upgrades that continue to meet emission standards are the only way for companies to develop and connect with international standards. Without core technology, our products are a pile of waste copper. iron."

According to the China Association of Automobile Manufacturers, the state-of-the-art engine emission technology is basically in the hands of large foreign companies from the State III to the State IV, and foreign commercial vehicle companies can easily launch new products that meet China IV, and China’s commercial vehicle companies Due to excessive pursuit of market share and ignoring the research and development of core technologies, technological upgrading has lags behind. At present, domestic enterprises can only introduce the technology of foreign companies to complete this technology upgrade. Facing the increase in the internationalization of new green energy strategies and emission standards, China should gradually increase the control of commercial vehicle emissions technology.

According to the latest statistics from the China Association of Automobile Manufacturers, the production and sales of commercial vehicles showed a negative year-on-year growth from January to May. Experts said that the strict implementation of State IV will lead to a significant decline in commercial vehicle sales in the second half of the year.
