What is the symbol for China V emission standards?
2 Answers
The symbol for China V emission standards is 'V', which belongs to the National Fifth Stage Emission Standards for motor vehicle pollutants. China V imposes stricter limits on nitrogen oxides (NOx), hydrocarbons (HC), carbon monoxide (CO), and particulate matter (PM) emitted by motor vehicles. The purpose is to reduce and prevent environmental pollution caused by vehicle exhaust, protect the ecological environment, and ensure human health. The requirements of China V are: 1. The CO emissions per kilometer driven by a vehicle must not exceed 1000 mg; 2. The non-methane hydrocarbon emissions per kilometer driven must not exceed 68 mg; 3. The NOx emissions per kilometer driven must not exceed 60 mg; 4. The fine particulate matter emissions per kilometer driven must not exceed 4.5 mg.
As someone who frequently tinkers with cars, the symbol for China's National Phase V emission standards is simply the two Chinese characters '国五', and sometimes you might also see the English version 'China V'. This label is affixed to the vehicle's engine compartment nameplate or accompanying documents, indicating that the vehicle complies with China's fifth-stage emission standards, primarily aimed at controlling exhaust pollutants. When repairing cars, I pay special attention to this symbol because it affects whether the vehicle can pass the annual inspection—emission testing thresholds are stricter for China V vehicles. I should also remind everyone that if the symbol is faded or missing from the documents, it might be due to improper maintenance or the vehicle's age, so it's best to check the electronic records at a 4S dealership. There are still quite a few China V vehicles on the market, which have better environmental performance than China IV but fall short of the latest China VI standards. In short, understanding this symbol can save you a lot of hassle when buying or transferring a car, especially since some older vehicles are prone to fraudulent modifications.
