In which year were China IV vehicles produced?
1 Answers
China IV vehicles were produced after 2011, with some being manufactured in 2010 or even earlier. The implementation of the China IV standard varied by region, with some areas adopting it earlier than others. In regions where the standard was implemented earlier, China IV-compliant vehicles were produced sooner. It wasn't until July 1, 2011, that the China IV standard was fully implemented nationwide. Below is some relevant information about the China IV standard: 1. The China IV emission standard is the fourth phase of China's motor vehicle pollutant emission standards. Compared to China III, it requires light-duty vehicles to reduce single-vehicle pollutant emissions by approximately 50%, heavy-duty vehicles to reduce emissions by about 30%, and particulate matter emissions by over 80%. 2. Different countries and regions adopt various emission standards based on their actual conditions. For example, the U.S. has U.S. standards, Europe has Euro standards (such as Euro IV and Euro V), and China has national standards (like China V and China VI). There are three main test cycles for passenger vehicle emissions: the EU's NEDC cycle, the U.S.'s FTP75 cycle, and Japan's JC08 cycle. China's standards are primarily based on European standards, while Japan's standards are more aligned with U.S. standards.
