When will the National VI emission standard for trucks be implemented?
2 Answers
The National VI emission standard for trucks was implemented on July 1, 2020. In some regions, the National VI standard was implemented in July 2019. Starting from July 1, 2020, all light-duty vehicles sold and registered must comply with the National VI standard a limit requirements. From July 1, 2023, all light-duty vehicles sold and registered must comply with the National VI standard b limit requirements. Here is a detailed introduction to the "National VI" standard: 1. Emission requirements: The "National VI" standard is an upgrade of the National V standard. Compared with the "National V" standard, "National VI" will strictly control the emission limits of pollutants. According to estimates, under the National VI emission standard, the emissions of carbon monoxide, hydrocarbons, non-methane total hydrocarbons, and nitrogen oxides from light-duty gasoline vehicles will be reduced by about 50% compared to the National V stage, and particulate matter emissions will be reduced by about 40%; for heavy-duty diesel vehicles, nitrogen oxides and particulate matter will be reduced by more than 60% compared to the National V stage. 2. Implementation stages: According to the plan, the "National VI" standard will be divided into two stages: 6A and 6B. The first stage starts on July 1, 2020, and vehicles below the 6A emission standard cannot be sold, registered, or licensed; the second stage starts on July 1, 2023, and vehicles below the 6B emission standard cannot be sold, registered, or licensed.
As a veteran truck driver with decades of experience, I must inform you about the implementation timeline of the China VI emission standards. The China VI-a phase for trucks started on July 1, 2021, and was upgraded to China VI-b on July 1, 2023. All newly manufactured heavy-duty trucks must comply with these standards. I still remember how our fleet was busy replacing or retrofitting old vehicles at that time, as non-compliant emissions would result in fines and affect annual inspections. Although the new regulations led to slightly higher vehicle prices and increased fuel costs, the reduced exhaust emissions have noticeably improved air quality on the roads. I always advise new drivers to choose China VI-compliant trucks when purchasing vehicles—it saves a lot of hassle, at least you won't have to worry about sudden inspections shutting down operations. Older vehicles can have their systems upgraded, but it requires some investment. I recommend visiting repair shops in advance to avoid peak traffic periods. In short, early preparation ensures a more worry-free driving experience.
