When was the China IV vehicle standard introduced?

[VanAdeline]

China IV emission standards were implemented starting in 2011. Here are specific details about emission standards: 1. Definition: The reason why China frequently updates emission standards is that with the increase in vehicle ownership, the environmental pollution caused by automobile exhaust has become increasingly severe. Vehicle exhaust contains harmful gases such as carbon monoxide and hydrocarbons, and emission standards set limits on the discharge of these gases. China's emission standards are primarily based on European Union standards, with some adaptive modifications made to suit local conditions. 2. Phase: Currently, China is in a transition period between China V and China VI standards. Many automakers have already launched models that comply with China VI standards, while China V standard models are being heavily discounted to clear inventory. Car buyers planning to purchase vehicles might be concerned about the implications of buying during this transition period. It's understood that currently, even vehicles meeting China VI standards still receive China V labels when being registered.
