In which year was China IV implemented?
2 Answers
Vehicles produced after July 1, 2011, comply with the China IV standard. Below is a detailed introduction to vehicle emission standards: 1. China III emission standard: The specific implementation dates were July 1, 2009, for light-duty diesel vehicles; July 1, 2010, for heavy-duty gasoline vehicles; and July 1, 2008, for heavy-duty gas and diesel vehicles. 2. China IV emission standard: The nationwide implementation dates were July 1, 2013, for light-duty diesel vehicles; July 1, 2013, for heavy-duty gasoline vehicles; January 1, 2011, for heavy-duty gas vehicles; and July 1, 2013, for heavy-duty diesel vehicles. 3. China V emission standard: Starting from July 1, 2017, the China V emission standard was fully implemented nationwide, with nitrogen oxide emissions reduced by 25% compared to the China IV standard and the addition of PM emission limits, making it more stringent. 4. China VI emission standard: The China VI standard is divided into two phases, 6A and 6B. The first phase began 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.
Recalling the National IV emission standards, I remember they were implemented in 2011. Back then, I had been driving a National III-compliant vehicle for several years. Suddenly, when the policy came into effect, many cities restricted high-emission vehicles from entering urban areas. The impact was huge, especially for someone like me who frequently traveled long distances. Older car models depreciated rapidly, and some even had to be scrapped or upgraded with emission control systems. The implementation of National IV marked a turning point, as car engines became more efficient, reducing carbon monoxide and particulate matter in exhaust emissions, gradually improving air quality. Although we're now promoting National VI standards, back in 2011, it drove technological advancements across the industry. I also started paying attention to emission labels when purchasing new cars to avoid restrictions or fines. In short, knowing this year is very practical for car owners, such as when buying or selling used cars to accurately assess their value.
