China 6 standard refers to the 'National Sixth Stage Emission Standards for Motor Vehicle Pollutants.' It includes 'Limits and Measurement Methods for Emissions from Light-duty Vehicles (China VI)' and 'Limits and Measurement Methods for Emissions from Heavy-duty Diesel Vehicles (China VI).' The following is an introduction to China 6: 1. Currently, the country divides the 'China 6 standard' into two phases: 'China 6a' and 'China 6b,' with plans to implement them nationwide uniformly in 2020 and 2023, respectively. 2. The China 6 standard, also known as the 'National Sixth Stage Emission Standards for Motor Vehicle Pollutants,' is formulated to implement environmental protection laws, reduce and prevent pollution from vehicle exhaust, protect the ecological environment, and ensure human health.
China 6 refers to the National Sixth Stage Emission Standards for motor vehicles, which essentially means the latest regulations set by the government for exhaust emissions from new vehicles. I remember when China 5 was still the mainstream during my time as a mechanic, but now newly manufactured vehicles must meet China 6b standards to be eligible for registration. These standards are much stricter than before, requiring significant reductions in harmful substances like carbon monoxide and nitrogen oxides in exhaust emissions. Automakers have to work hard to improve engine technology, and features like the GPF (Gasoline Particulate Filter) have become standard. Environmental authorities are also enforcing these regulations strictly, making it impossible to sell non-compliant vehicles. Last year, several customers at our shop were in a hurry to switch to China 6-compliant cars, fearing they wouldn’t pass annual inspections.
