China 6 refers to the National Sixth Stage Emission Standards for Motor Vehicles, which include: emission limits and measurement methods for pollutants from light-duty vehicles, as well as emission limits and measurement methods for heavy-duty diesel vehicles. The purpose is to prevent environmental pollution caused by exhaust emissions from compression-ignition and gas-fueled spark-ignition engine vehicles, protect the ecological environment, and safeguard human health. The China 6 standards are: 1. A 50% reduction in carbon monoxide emissions from gasoline vehicles; 2. A 50% reduction in total hydrocarbon and non-methane hydrocarbon emission limits; 3. A 42% reduction in nitrogen oxide emission limits.

China 6 is the sixth-stage national standard for motor vehicle pollutant emissions in China. Simply put, it's the government's stricter regulations on exhaust emissions from new vehicles. It requires significant reductions in harmful gases like nitrogen oxides and particulate matter compared to the previous China 5 standard. Behind this lies technological upgrades, such as more efficient catalytic converters and more precise engine control. As a tech enthusiast, I think this is great because it pushes automakers to innovate, making new cars more environmentally friendly. Although car prices may rise slightly, in the long run, it reduces air pollution and benefits public health. Nowadays, most new cars sold are already China 6 compliant, and they feel cleaner to drive, with exhaust that doesn't smell as pungent. China 6 is further divided into phases a and b, with b being stricter and fully implemented after 2023. Car owners should note that China 6 vehicles require more meticulous maintenance, such as using high-quality engine oil to avoid filter clogging. Overall, this is progress toward cleaner urban air.

I've been driving for decades, and China 6 is the latest emission standard introduced by the government, meaning new vehicles must reduce exhaust pollution. Specifically, it imposes stricter limits on harmful emissions like nitrogen oxides compared to the older China 5 standard. After its implementation, my old China 5 car depreciated because the used car market now favors China 6 vehicles. Although new cars are a bit more expensive, they are more reliable and have fewer issues. In daily driving, China 6 cars feel smoother, emit less exhaust, and are more environmentally friendly. It's recommended that car owners perform regular maintenance, such as checking the exhaust system and replacing filters, to comply with the new standard. In the long run, this policy is beneficial—it reduces smog and makes roads healthier. However, it's important to note that China 6 vehicles require higher-quality fuel, so it's essential to use good fuel from reputable gas stations.
