In which year was the China IV vehicle introduced?

Cars produced after July 1, 2011, comply with the China IV standard. Below is a detailed introduction to the vehicle emission standards: China III emission standard: The specific implementation times were: light-duty diesel vehicles on July 1, 2009; heavy-duty gasoline vehicles on July 1, 2010; heavy-duty gas vehicles on July 1, 2008; and heavy-duty diesel vehicles on July 1, 2008. China IV emission standard: The nationwide implementation times were: light-duty diesel vehicles on July 1, 2013; heavy-duty gasoline vehicles on July 1, 2013; heavy-duty gas vehicles on January 1, 2011; and heavy-duty diesel vehicles on July 1, 2013. China V emission standard: The nationwide implementation of the China V emission standard began on July 1, 2017. Compared to the China IV standard, nitrogen oxide emissions were reduced by 25%, and a PM emission limit was added, making it more stringent. China VI emission standard: The China VI standard is divided into two phases: 6A and 6B. The first phase started on July 1, 2020, prohibiting the sale, registration, and licensing of vehicles below the 6A emission standard. The second phase starts on July 1, 2023, prohibiting the sale, registration, and licensing of vehicles below the 6B emission standard.
The implementation of China's National IV emission standards for vehicles, I recall, began around 2008. At that time, environmental issues were becoming increasingly severe, with urban smog causing widespread public concern, prompting the government to upgrade emission regulations. In July 2008, the National IV standard officially took effect for light-duty vehicles such as passenger cars, requiring significant reductions in tailpipe pollutants like carbon monoxide and particulate matter. Vehicles were equipped with advanced technologies like catalytic converters. By 2010, the standards expanded to cover heavy-duty vehicles like trucks and buses, with the entire automotive industry swiftly adapting. I remember back then, purchasing a car suddenly came with an additional requirement—new vehicles had to meet the standards for registration, otherwise they couldn't be legally driven. The environment did show some improvement, with PM2.5 concentrations dropping slightly, and consumers began favoring low-emission vehicles more. Later, National V and VI standards were successively introduced, marking further progress on this environmental protection journey.
