1 Answers
After the implementation of National VI standards, National IV vehicles that are already registered can still be driven on the road. Below are some relevant details about the National VI standards: 1. Emission Limits: The National VI standard emission limits are as follows: National VI A: carbon monoxide 700mg/km, non-methane hydrocarbons 68mg/km, nitrogen oxides 60mg/km, PM fine particles 4.5mg/km, etc.; National VI B: carbon monoxide 500mg/km, non-methane hydrocarbons 35mg/km, nitrogen oxides 35mg/km, PM fine particles 3mg/km, etc. 2. Impact: After the implementation of National VI standards, only the registration of new National V vehicles will be affected. Registered National V and National IV vehicles that have passed annual inspections will not be affected and can continue to be used normally.
