Which Year Does China IV Vehicles Belong To?
2 Answers
China IV vehicles were produced after 2011, with some also manufactured in 2010. Here is more relevant information: 1. China IV Emission Standard: The China IV emission standard is the national fourth-phase motor vehicle pollutant emission standard. Compared to China III, it requires light-duty vehicles to reduce single-vehicle pollutant emissions by approximately 50%, heavy-duty vehicles to reduce single-vehicle emissions by about 30%, and particulate matter emissions by over 80%. 2. About Passenger Vehicle Emission Test Cycles: Different countries and regions adopt different emission standards based on their actual conditions. For example, the United States has the U.S. standard, Europe has the Euro standard (Euro IV, Euro V, etc.), and China has the China standard (China V, China VI, etc.). However, there are mainly three test cycles for passenger vehicle emissions: the EU's NEDC cycle, the U.S.'s FTP75 cycle, and Japan's JC08 cycle. The China standard is primarily formulated with reference to the Euro standard, while Japan's standard is more influenced by the U.S. standard.
The implementation year of China IV vehicles mainly focused around 2010, which is a key milestone in analyzing emission standards from a technical perspective. I recall that the China IV standard for light-duty gasoline vehicles was mandatorily enforced nationwide in the first phase starting from July 2010, while diesel vehicles began full promotion from 2013. In practical terms, the production date on the vehicle or the registration certificate can be used to confirm the year, for example, most new cars produced in 2010 meet the China IV requirements. The purpose of the standard upgrade is to reduce pollutant emissions, such as hydrocarbons and carbon monoxide, which must be significantly reduced. I often check the vehicle's environmental label or consult professional reports from 4S shops. If encountering issues with identifying older vehicles, it's best to verify the year's reliability using the VIN code query system to avoid misunderstandings caused by early implementation or regional differences, ensuring clarity when purchasing or maintaining a vehicle.
