Recently, Shenzhen and Guangzhou have successively implemented the National Sixth Emission Standard for Light Vehicles, which has become a hot topic in the industry.

  On May 7, 2018, the website of the Guangzhou Municipal Environmental Protection Bureau posted a "Notice on the Implementation of the Sixth National Motor Vehicle Air Pollutant Emission Standards for Light Vehicles (Draft for Comment). Among them, a plan was proposed to implement the National Sixth Standard for light vehicles newly registered locally and transferred from outside the country from January 1, 2019.

  More active than Guangzhou is Shenzhen.

  As early as March 29, 2018, the Shenzhen Municipal Committee on Human Settlements and Environment issued the "Shenzhen Human Settlement and Environment Committee and the Traffic Police Bureau of Shenzhen Public Security Bureau on the implementation of the sixth phase of the National Motor Vehicle Air Pollutant Emission Standard (F) Notice (draft for comments).

This notice (draft for comments) stipulates that: from July 1, 2018, the light diesel vehicles sold, registered and transferred in Shenzhen should meet the National Sixth Standard; from January 1, 2019, Shenzhen sales and registration The light gasoline vehicles transferred to and from them should meet the National Sixth Standard.

  ● Shenzhen and Guangzhou will implement National Six five years in advance

  According to the unified requirements of the Ministry of Environmental Protection, the implementation time of the "National Six" standard is divided into two phases. From July 1, 2020, all light vehicles sold and registered should meet the 6a standard requirements of the "National Six" standard. Beginning July 1, 2023, all light vehicles sold and registered should meet the 6b limit requirements of the "National Sixth" standard.

Shenzhen and Guangzhou not only plan to implement China ’s National Sixth Emission Standard for Light Vehicles in advance, but also intend to cross the implementation stage of China ’s National Sixth Year Light Vehicles and directly implement the stricter National Sixth Emissions Standard for Light Vehicles ahead of schedule. This is much earlier than the original plan. For 5 years.

  ● What are the issues to be avoided when National Six is ​​coming?

  It is not an easy task to upgrade from the fifth to the sixth national level. It will be a big challenge for the government, as well as for manufacturers and car owners.

  1. Fuel quality comes first

  From the perspective of supply, China ’s fuel quality is low, and there is still a large gap compared with developed countries. Poor fuel quality will directly lead to increased exhaust emissions. Therefore, we want to finally achieve the National Six emission target, fuel quality. It is first to be promoted.

  Beginning in October 2017, cities in 6 provinces including Beijing, Tianjin, Hebei, Shandong, Shanxi, and Henan have banned the sale of gasoline and diesel for vehicles below the "National Six" standard, and more and more regions will begin in the future. Provide national six oil.

  2. Engine manufacturers: facing a severe test

  For a car, reducing emissions also affects fuel consumption and power performance. For an automobile company, the standard is upgraded again and again, and emissions treatment will become more and more complicated, and the increase in research and development costs is inevitable.

  From the just-implemented "National V" to the forthcoming "National VI" full implementation, less than two years have been left for auto manufacturers. For many cities, the transition time is only one or two years. The implementation of "National Six" in 2020 is slightly tense in terms of time. The key to implementing the National Sixth Standard is to upgrade the engine and aftertreatment system, which will be a severe test for domestic light engine manufacturers.

  3. Vehicle manufacturers: Frequent updates of standards make it difficult for automakers to keep up

  Too densely and frequently set and change standards, it is difficult for many companies to keep up with the pace, especially for self-owned brand car companies with relatively weak vehicle technology research and development capabilities.

  Even if individual large companies can predict that the new emission standards will be in line with international standards and develop engines in advance, the product development may be already 2020, and even if the products have been released, they can only be assembled on individual models. Cannot expand across the board.

  4. Difficult market promotion: the pressure of rising costs is difficult to digest

  Due to the lower emissions limits of diesel vehicles before China ’s “National V”, diesel vehicles are more difficult to upgrade than gasoline vehicles. The upgrade cost of a light gasoline vehicle is about 1,200 yuan, while the upgrade cost of a light diesel vehicle is about 4,000 yuan.

  In order to adapt to the "National Six" standard, car companies will invest more in the research and development costs of vehicle emissions. As the saying goes, "wool comes from sheep", the final cost increase may still be fed back to the car price. It also costs a small amount for a vehicle to pass the "National Six" certification, which will also increase the purchase cost of the vehicle. In addition to changes in the vehicle engine and after-treatment system, the National Six vehicle will also face subsequent maintenance costs. rise.

  Various factors have led to low acceptance of the implementation of the National Six Standards by users, and the general attitude is to refuse, which also makes it very difficult to promote policies.

  The formal adoption of National VI heavy-duty vehicle emission standards has made China one of the countries with the strictest control of heavy-duty vehicle emissions in the world. This is the inevitable result of technological progress and social development.

  But at the same time, we must learn from previous experiences and try to avoid possible problems. From the feedback from engines, OEMs and users, it can be found that all sectors are generally questioning the current implementation of State VI.

  In this regard, Gong Huiming, director of the Energy Foundation's China Transportation Project, said: "We must attach great importance to the implementation of the National Sixth Standard, effectively strengthen the supervision of production consistency and in-use durability, and ensure that the main responsibility of the manufacturer should not be passed on. To the end consumer, promote healthy market competition, and establish a mechanism for survival of the fittest, this is the key to the functioning of the standard, so that the expected results can be truly achieved. "

  In any case, the pace of National Six is ​​getting closer.
