What is the Difference Between China 5 and China 6 Vehicles?
2 Answers
The difference between China 5 and China 6 vehicles lies in their exhaust emissions: 1. China 5 vehicles: The limit for carbon monoxide content in the exhaust is 1000mg per kilometer; 2. China 6 vehicles: The limit for carbon monoxide content in the exhaust is 700mg per kilometer. Vehicle emission standards refer to regulations on the content of harmful gases such as carbon monoxide, hydrocarbons, nitrogen oxides, particulate matter, and soot in the exhaust. Solutions for vehicles failing to meet emission standards include: 1. Cleaning the throttle valve, catalytic converter, and fuel injectors; 2. Replacing piston sealing rings and oxygen sensors; 3. Using high-quality fuel.
The main difference between China 5 and China 6 standards lies in engine technology. China 6 vehicles have upgraded after-treatment systems, with an additional particulate filter installed near the engine specifically to capture fine particles in exhaust gases. You can see that the nitrogen oxide emission limits for China 6 vehicles are over 40% lower than China 5 standards. The most noticeable difference in actual driving is that you can hardly smell gasoline during cold starts. Moreover, China 6 vehicles are equipped with real-time monitoring modules that immediately trigger warning lights if emissions exceed standards. As for drawbacks, China 6 vehicles are particularly picky about fuel quality—my neighbor's car had its particulate filter clogged after using the wrong fuel, costing over 3,000 yuan to repair.
