According to the regulations of the National Environmental Protection Agency, starting from July 1, 2008, the China Phase III emission standard was implemented for vehicles with a maximum total mass of 3500kg as approved by the National Development and Reform Commission's vehicle model announcement. Therefore, the China III standard was implemented from July 1, 2008. More information about China III: 1. The China III standard refers to China's third-stage vehicle emission standard. 2. The national third-stage emission standard is equivalent to the European Euro III emission standard, meaning the content of tailpipe pollutants is equivalent to Euro III. The difference is that new vehicles must be equipped with an OBD, i.e., an onboard self-diagnostic system.
