Since the European Union unveiled its proposal for the seventh phase of European emission standards, there has been little speculation about China VII. On December 7, the first issued the notice of the "Action Plan for Continuous Improvement of Air Quality", which clearly proposed to "study and formulate the next stage of motor vehicle emission standards", which is undoubtedly to provide reliable support for the formulation and introduction of the national seven, after all, the domestic emission standards have reached the national six stage, and the next stage is naturally the national seven.
Looking back on China's motor vehicle emission standards, from the implementation of the national one standard in 2001 to the full implementation of the national six emission standards 6b stage, more than 20 years, five changes and upgrades, each upgrade is a challenge to the research and development strength of car companies, but also caused the cost of car owners and vehicle operation restrictions.
As we all know, China's vehicle emission standards have been using the European system, and the formulation plan of the national seven emission standards may also be affected by Euro VII to a certain extent. Let's first take a look at what Euro 7, known as an "air purifier", contains.
The main content of Euro VII:
1. Vehicle nitrogen oxide emissions are reduced to 30 milligrams per kilometer, and carbon monoxide emissions are reduced to 100-300 milligrams. At the same time, it is made clear that all cars and vans sold in the EU will achieve zero CO2 emissions by 2035.
2. For pollutants that were previously unregulated, such as nitrous oxide emitted by heavy-duty diesel vehicles, Euro VII also limits the emission value, which puts forward higher and more complex requirements for the post-processor of trucks to a certain extent.
3. It is required that the iron filings and dust generated by the friction between the brake pads and the brake drum or brake disc during vehicle braking are included in the scope of pollutant restrictions.
4. Measure the vehicles that use Euro 7 for a longer period of time until these vehicles reach 200,000 kilometers or 10 years old.
5. Euro VII will standardize the durability of battery packs installed on vehicles to reduce the need for key raw materials needed to produce batteries.
6. Make full use of digital management to ensure that vehicle emission standards will not be tampered with by the outside, and that authorities can measure the emissions of the vehicle throughout its life cycle through sensors inside the vehicle, so as to control emissions more easily.
France, Italy, the Czech Republic, Bulgaria, Hungary, Poland, Romania and Slovakia even signed a joint document calling for the cancellation of Euro 7, saying it was too radical or even unrealistic for car companies. In this context, Spain, as the current Presidency of the Council of the European Union, came forward to submit a compromise draft, which was also adopted by the Council of the European Union. The relevant elements of the compromise draft are said to be much less powerful than the original version.
As for whether China's national seven will be as strict as the European seven, it is still unknown. After all, from the perspective of national conditions, China's power resources mainly rely on coal to provide, if blindly pursue the replacement of fuel engines with electric motors, the amount of carbon dioxide produced by coal to obtain power resources, than the amount of carbon dioxide emitted by the fuel engine itself, how much can be reduced, is still inconclusive. In addition, if you want to replace the fuel engine in large quantities in a short period of time, it is a great challenge for the country's power facilities and power generation facilities.
It is worth mentioning that the upgrading of emission standards is an international trend, and it is probably expected that China's emission standards will continue to tighten. Although fuel vehicles in the domestic long-distance transportation market are still the main force, whether it is regulations, purchase preferences, the right of way or the concept of consumption, the market share of fuel vehicles is being eroded little by little, when the emission standards are tightened again, fuel vehicles will once again face the test of technological upgrading, the production cost of vehicles will rise sharply, and ultimately can only be borne by consumers.
At present, the sales volume of diesel vehicles on the market has been declining, and the comprehensive sales of pure electric and hybrid models have gradually exceeded that of diesel vehicles.
