What is the symbol for China 4?
3 Answers
China 4 symbol is China IV. Below is a partial introduction about China 4:1. Introduction: The China 4 emission standard is the national fourth-stage motor vehicle pollutant emission standard. The main pollutants emitted by vehicles include HC (hydrocarbons), NOx (nitrogen oxides), CO (carbon monoxide), PM (particulate matter), etc. By applying technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices, the standard controls and reduces vehicle emissions to below specified levels.2. Vehicle exhaust purification: Vehicle exhaust purification refers to the process of converting toxic gases in vehicle exhaust into non-toxic gases before releasing them into the atmosphere, thereby reducing pollution to the atmospheric environment.
I've been driving for over a decade, and the China IV emblem is extremely common! It's actually that blue environmental label stuck on the corner of the windshield, clearly marked with 'China IV' and printed with vehicle parameters below. This emblem is particularly important—when buying a used car, just check the nameplate on the passenger door frame, and it will also indicate compliance with the China IV standard. In certain restricted zones on the road, like those with strict environmental controls in Beijing, Shanghai, and Guangzhou, older cars without this emblem basically can't enter the city center. Remember to check the label color during vehicle transfer inspections; the blue one is a newer standard than the yellow China III label.
Just encountered this issue the other day while buying a car - a 2014 Passat had its nameplate marked as 'China IV'. In the current used car market, vehicles manufactured between 2011 and 2017 mostly carry the China 4 standard, clearly registered on the green book. If a dealer claims it's China 4 but the label is missing, insist on seeing the original environmental compliance document. The printed 'GB18352.3-2005' in the emission standard section on the third page is the irrefutable proof. Before transferring ownership, it's best to check the local environmental protection bureau's website - places like Shandong currently don't allow the transfer of China 4 diesel vehicles.
