What is the China VI standard?
2 Answers
China VI standards are divided into China VIa and China VIb. Below is a partial introduction about the China VI standards: 1. China VI: The implementation timeline of the China VI emission standards is divided into two phases, "China VIa" and "China VIb," with corresponding effective dates of July 1, 2020, and July 1, 2023, respectively. The symbols for China I to China VI are: China I, China II, China III, China IV, China V, and China VI. 2. Pollution control emission standards: The government has issued a series of motor vehicle tailpipe pollution control emission standards, marking the gradual establishment of automotive emission standards. China introduced its first-phase emission standards by referencing European emission standards, followed by China II, China III, China IV, and China V, with each phase imposing stricter emission requirements than the previous one.
The China 6 standard refers to the sixth-stage motor vehicle emission standard in China, which mandates that harmful gases emitted by vehicles must be kept at very low levels. As someone who studies automotive technology, I know that China 6 is divided into two phases: 6a and 6b, with 6b being more stringent. The primary goal is to reduce pollutants like carbon monoxide and nitrogen oxides. Vehicles must pass the WLTC test cycle for verification, which is more reflective of real-world driving compared to older standards. Identifying a China 6-compliant vehicle is straightforward: new cars have an environmental label on the windshield with the words 'China 6,' or you can check the vehicle conformity certificate. The China 6 standard was introduced to address air pollution issues, such as urban smog, leading to more eco-friendly engine designs, like upgraded three-way catalytic systems, and overall more efficient and energy-saving vehicle performance. As a car owner, upgrading to a China 6-compliant vehicle also comes with tax benefits, easier registration in some regions, and long-term advantages in maintenance costs.
