Which Year's Cars Comply with China V Emission Standards?
2 Answers
China V emission standards were implemented for vehicles in 2012. The China V emission standard's control level is equivalent to Europe's Stage V emission standard. Compared to China IV standards, China V standards reduce nitrogen oxide emissions by 25% for light-duty vehicles and 43% for heavy-duty vehicles. Methods to check a vehicle's emission standard include: 1. Review the motor vehicle conformity certificate; 2. Check the vehicle's accompanying documents; 3. Visit the official website for motor vehicle emission supervision and management; 4. Examine the back of the environmental label on the vehicle's front windshield; 5. Bring the vehicle registration form to the local vehicle management office for inquiry. Major automotive pollutants include hydrocarbons, nitrogen oxides, carbon monoxide, and particulate matter. Through technologies such as catalytic converter active layers, secondary air injection, and cooled exhaust gas recirculation systems, these emissions are controlled and reduced to levels below regulated standards.
I've been running an auto repair shop for over a decade, and people often ask which year the China 5 emission standard vehicles are from. Actually, this varies by region. Beijing and Shanghai were the earliest, requiring all newly registered vehicles to meet China 5 standards starting from 2016. Nationwide, the mandate for gasoline vehicles came into effect in July 2017, while diesel vehicles had until January 2018. From my repair experience, I've noticed a pattern: checking the production date on the vehicle's nameplate is the most accurate method. Some automakers started releasing China 5 compliant models as early as the second half of 2015. Special caution is needed when purchasing used cars from other regions, as some areas implemented the standards later. For example, vehicles registered before 2017 might still be China 4 compliant. Emission standards directly affect vehicle transfer and annual inspections, and getting it wrong can cause significant trouble.
