In which year was China III implemented?

[Ricardo]

China III vehicle emission standards were officially implemented on July 1, 2008, marking the "starting time" of China III. On July 1, 2013, China IV standards came into effect, prohibiting the registration of China III vehicles. To stably meet China III emission standards, vehicles must be equipped with technical measures that ensure pollutant emissions comply with China III standards, while using fuel that meets Euro III standards. Below is relevant information about China III vehicles: 1. The so-called China III standard refers to China's third-stage vehicle emission standard; 2. China's third-stage emission standard is equivalent to the Euro III emission standard, meaning the content of tailpipe pollutants is equivalent to Euro III levels, with the difference being that new vehicles must be equipped with an OBD (On-Board Diagnostics) system; 3. The characteristics of the OBD system include increased detection points and detection systems, with oxygen sensors installed at both the inlet and outlet of the three-way catalytic converter. Compliance is fully ensured through real-time monitoring of vehicle emissions, guaranteeing stricter enforcement of Euro III emission standards.
