Does it affect the annual inspection?, Starting from now on, the implementation of the National VI Emission Standards for automobiles in China will begin in Stage 6b | Standards | Emissions
Starting today, the national level will fully implement the 6b stage of the National VI emission standard for automobiles, and prohibit the production, import, and sale of vehicles that do not meet the 6b stage of the National VI emission standard.
Starting from today, the implementation of the National VI emission standard 6b phase for automobiles nationwide
National 6b mainly targets the requirements for newly produced vehicles by automotive companies, and this emission standard increase includes light vehicles, heavy-duty diesel, and gas vehicles. The production date shall be based on the vehicle manufacturing date on the automobile certificate of conformity; The import date shall be based on the arrival date indicated on the goods import certificate; The sales date is based on the date of the car sales invoice.

When formulating the National VI emission standards, considering that China's automobile emission standards have undergone years of technological upgrades and have reached the opportunity to benchmark against advanced standards in Europe and America, stricter National 6b emission standards have been set. However, in the specific implementation process, considering the difficulties and pressures faced by automobile enterprises in product planning, equipment upgrading, and product production line switching, both light and heavy vehicles have set relatively loose 6a requirements, while the weak research foundation, high difficulty, and long technology development cycle requirements have been placed in the 6b stage.
Yin Hang, Deputy Director of the Motor Vehicle Emission Monitoring Center of the Chinese Academy of Environmental Sciences: Compared to 6a, 6b has further tightened its limits. Taking light vehicles as an example, carbon monoxide, hydrocarbons, nitrogen oxides, and particulate matter have all decreased by 30% to 50%. Secondly, there have been changes in the content and requirements of testing, with the implementation of actual driving emission testing and in vehicle emission testing requirements. Vehicles are required to not only meet emission standards during laboratory testing, but also meet emission standards on actual roads.
In the actual testing process, China 6b requires vehicles to meet corresponding pollutant emission requirements under different environmental temperatures, load conditions, and altitudes. At the same time, the durability requirements for the exhaust emission control devices of light-duty vehicles in China 6b have been extended from 160000 kilometers to 200000 kilometers; Heavy duty vehicles require remote online monitoring, which means that vehicles that meet the requirements of national 6b standards should transmit real-time engine operating status and corresponding pollutant emission concentration data to environmental regulatory authorities, improving the level of intelligent big data supervision.

National 6b has no impact on the annual inspection of in use vehicles
The national 6b emission standard belongs to the emission standard for new vehicles and has no impact on the annual inspection of vehicles currently in use.
According to the management principle of "new standards for new cars, old standards for old cars", the scope of implementing the new standards includes the sale of new cars and vehicles that have applied for license plates for the first time. For vehicles that have previously obtained license plates, they are not limited by the implementation of the new standards, but must still meet the requirements of the original relevant emission testing standards.
