What National Standard Does China VI Correspond To?
3 Answers
China VI is equivalent to the National VI emission standard. The National VI emission standard, often referred to as the most stringent emission standard in history, brings significant benefits. It requires a 50% reduction in carbon monoxide emissions, a 42% reduction in total hydrocarbons, and a 33% reduction in particulate matter compared to previous standards. Compared to the National V standard, the National VI standard nearly doubles these reductions. Here are some additional details: Related Standards: The National VI standard was issued by the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection and Quarantine on December 23, 2016, and June 22, 2018, respectively. The "Limits and Measurement Methods for Emissions from Heavy-Duty Diesel Vehicles (China VI)" came into effect on July 1, 2019. The implementation of the National VI standard imposes stricter requirements on emissions such as carbon monoxide, nitrogen oxides, and hydrocarbons.
I used to be very interested in automotive emission standards. China's National VI is actually the sixth-stage standard for vehicle exhaust emissions in our country. The main purpose of this standard is to control pollutants emitted by vehicles, making cars cleaner and more environmentally friendly. For example, it imposes stricter limits on nitrogen oxides and particulate matter emissions compared to the previous National V standard. I often chat with fellow car enthusiasts about its benefits for air quality—after implementation in big cities, it truly helps reduce smog and health issues. The National VI standard was first implemented in 2019 for newly registered vehicles, and now it's being promoted nationwide. When buying a new car, it's best to choose one that meets this standard. Although it might sound a bit technical, simply put, it's a regulation set by the country to make vehicles greener, and we should all pay more attention to environmental protection in our daily driving.
As someone who frequently works on car repairs, let me talk about the China VI standard. It's the sixth version of China's emission standards, essentially setting stricter rules for vehicle emissions to control harmful substances like carbon monoxide and hydrocarbons. Technically, it upgrades the testing method from the old NEDC to WLTC, which is closer to real-world driving conditions, ensuring the data isn't falsified. Car manufacturers have to put effort into modifying engines and exhaust systems to meet the standard. I've worked on many older cars from before the standard change, and their emission issues were noticeably worse. Nowadays, most new cars comply, but regional differences should be noted—some prefecture-level cities implemented the standard later. Overall, China VI represents a significant step forward in vehicle emission reduction, and it's quite substantial.
