In which years were China III vehicles produced?

[EloiseLynn]

China III vehicles generally refer to cars produced between 2007 and 2011, with the nationwide implementation date starting from July 1, 2007. According to Announcement No. 5 of 2006 by the National Environmental Protection Administration, 'Announcement on the Release of New Motor Vehicle Models and Engine Types Meeting the National Phase II and Phase III Emission Limits for Motor Vehicles,' the China III standard mainly applies to light gasoline and diesel vehicles under 3.5 tons, equivalent to the Euro III standard. The so-called China III standard refers to China's third-stage vehicle emission standard. The national third-stage emission standard is equivalent to the Euro III emission standard, meaning the pollutant content in exhaust emissions is similar to Euro III levels. The difference is that new vehicles must be equipped with an OBD (On-Board Diagnostics) system. The characteristics of the OBD system include an increased number of 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 the Euro III emission standard. Compared to China II vehicles, China III vehicles are more fuel-efficient. Models around 5 tons save approximately 1 liter per 100 kilometers, while 10-ton models save about 2 liters. However, this applies primarily to long-distance and stable driving conditions. For short-distance operations, the impact on fuel consumption is minimal. China's emission standards are categorized as follows: China I, China II, China III, China IV, China V, and China VI. As of December 31, 2018, the national standard for light gasoline vehicles was China V. The China VI emission standard is implemented in two phases: Phase 1: Starting from July 1, 2020, all vehicles sold and registered must comply with the China VI A standard. Phase 2: Starting from July 1, 2023, all vehicles sold and registered must comply with the China VI B standard. Some cities may advance the implementation of the China VI emission standard for light vehicles to January 1, 2019.

I've encountered this issue before. Vehicles complying with the China III emission standards were mainly produced around 2007, as the Chinese government officially implemented the third-phase emission standards that year. I remember many of my friends bought their cars around 2008, just catching this wave. This standard primarily aims to control vehicle pollutants, such as reducing carbon monoxide and nitrogen oxides, which greatly benefits environmental protection. With the advancement of China III, older vehicles like China I and China II were gradually phased out, which I think is great as the air has become much cleaner. However, when buying used cars, you need to be careful. Some major cities now restrict China III vehicles, so it's best to check the vehicle's manufacturing date by looking at the registration certificate or VIN code to confirm the year. Overall, understanding this can help everyone make wiser choices when selecting a car.
