From which year did China National III vehicles start?

[SanBrianna]

China National III vehicles began with the implementation of the National III standard on July 1, 2008, which marks the 'starting time' of National III. Below are relevant details about National III: 1. The so-called National III standard refers to China's third-stage vehicle emission standards; 2. The National III emission standard is equivalent to the European Euro III emission standard, meaning the content of tailpipe pollutants is comparable to Euro III. The difference is that new vehicles must be equipped with an OBD, or On-Board Diagnostics system; 3. The On-Board Diagnostics system features an increased number of detection points and systems, with oxygen sensors installed at both the inlet and outlet of the three-way catalytic converter. It ensures compliance by monitoring vehicle emissions in real-time, thereby better guaranteeing the enforcement of the Euro III emission standards.
