How to Distinguish Whether a Vehicle is China III, China IV, or China V?
1 Answers
Methods to distinguish whether a vehicle is China III, China IV, or China V include: 1. The vehicle's factory certificate clearly indicates the standard; 2. Check the engine emission label; 3. The annual inspection label clearly indicates the standard; 4. Visit the Motor Vehicle Environmental Protection Website, enter the engine number and manufacturer name for new vehicle certification, and search for the vehicle's certification announcement, which explicitly states the emission standard. China III, China IV, and China V are common terms for China's various stages of vehicle emission standards. China III refers to the third stage of China's vehicle emission standards, which upgraded and modified the engine and exhaust system to reduce pollutant emissions, added vehicle self-diagnosis systems, and improved the three-way catalytic converter. China IV is the fourth stage of China's vehicle emission standards, which upgraded the post-emission treatment system compared to China III, reducing pollutant emissions by 50% to 60%. China V is the fifth stage of China's vehicle emission standards, imposing stricter limits on vehicle emissions such as nitrogen oxides, hydrocarbons, carbon monoxide, and particulate matter. Compared to China IV, the China V standard requires a 25% reduction in nitrogen oxide emissions and adds emission limits for non-methane hydrocarbons and PM, further reducing atmospheric pollution.
