What does Guovl mean?

Guovl refers to China's National VI emission standard for vehicles, which imposes strict limits on pollutant emissions. Under this standard, carbon monoxide emissions from gasoline vehicles are reduced by 50%, total hydrocarbons and non-methane hydrocarbon emission limits are lowered by 50%, and nitrogen oxide emission limits are tightened by 42% (excluding operating conditions and testing influences). The National VI standard represents China's sixth-stage motor vehicle pollutant emission standard, aimed at preventing environmental pollution from exhaust emissions of compression-ignition and gas-fueled spark-ignition engine vehicles, protecting the ecological environment, and safeguarding human health.
I think China 6 is actually the sixth stage of China's automobile emission standards, simply put, it sets stricter pollutant emission limits for new vehicles. For example, it requires a significant reduction in nitrogen oxides and particulate matter in vehicle exhaust, promoting the adoption of advanced technologies such as particulate filters or better three-way catalytic converters. As a car enthusiast, I believe this is good for driving technological progress and also makes the overall air cleaner. China 6 is divided into two sub-stages, 6a and 6b, and most new cars on the market now comply with the 6b standard, which is much stricter than the previous China 5. If you're planning to buy a new car, I recommend prioritizing China 6-compliant vehicles because they are more environmentally friendly, have relatively lower maintenance costs, and higher resale value in the long run. After all, once the policy is implemented, second-hand cars with older standards may face restrictions, so it's always wise to adopt the new standard early.
