What are the differences between China 6 and China 5 vehicle emission standards?
2 Answers
Here are the specific differences between China 6 and China 5 vehicle emission standards: 1. Different control levels: The China 5 standard's emission control level is equivalent to Europe's currently implemented Stage 5 emission standard. The China 6 standard for motor vehicle pollutant emissions was established to prevent environmental pollution from exhaust emissions of compression-ignition and gas-fueled spark-ignition engine vehicles, protect the ecological environment, and safeguard human health. 2. Different release dates: The China 5 standard was released on September 17, 2013. The China 6 standard was released on June 22, 2018. 3. Different issuing authorities: The China 5 standard was issued by the Ministry of Environmental Protection. The China 6 standard was jointly issued by the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection and Quarantine.
As a daily driver, I believe the main difference between China 6 and China 5 lies in the stricter emission standards. China 6 vehicles significantly reduce nitrogen oxide and carbon monoxide emissions, cutting pollutants by nearly 50%, which helps improve air quality. When buying a car, the China 6 version is usually more expensive, but it’s more fuel-efficient in the long run, offering better cost-effectiveness. In major cities like Beijing and Shanghai, China 5 vehicles may face traffic restrictions, preventing them from entering city centers on weekdays, which affects commuting. It’s also important to use low-sulfur fuel, as China 6 requires cleaner fuel. During maintenance, emission system checks are stricter, and any issues must be fixed promptly to avoid fines. Driving a China 6 car also gives peace of mind, as it’s less harmful and more environmentally friendly. Overall, while the initial cost of choosing China 6 is slightly higher, it’s a worthwhile investment from both an environmental and convenience perspective.
