What is the equivalent of Euro 6 in China's emission standards?
2 Answers
Euro 6 standard is equivalent to China's National 6a emission standard. The following are the management and hazards of automobile exhaust: Management of automobile exhaust: This should be approached from two aspects. One is control technology, mainly improving fuel combustion efficiency, installing pollution prevention treatment equipment, and developing new types of engines. The other is administrative measures, including scrapping and renewing old vehicles, phasing out outdated cars, developing new types of vehicles (i.e., motor vehicles with no pollutant emissions), and controlling fuel usage standards. Hazards of automobile exhaust: While directly harming human health, exhaust emissions also have profound impacts on the environment. Sulfur dioxide in the exhaust has a strong irritating odor and, when reaching certain concentrations, can easily lead to "acid rain," causing soil and water sources to acidify and affecting the growth of crops and forests.
As an experienced car owner, I have some knowledge about emission standards. Euro 6 is roughly equivalent to China's China 6 standard, which is further divided into two phases: a and b. Euro 6a/b is similar to China 6a, while Euro 6c/d is closer to China 6b, but China 6 has stricter limits on particulate matter. When buying a car, I pay special attention to this, especially for imported vehicles, which must meet China 6b standards to be registered, otherwise they cannot be driven in cities. The safest way is to verify the data on the environmental protection bureau's official website or app, and don't trust merchants' casual claims. Driving low-emission vehicles is not only environmentally friendly but also saves fuel and money. When I changed my car, I chose a China 6b model, which emits much less exhaust, and the air quality on my commute has noticeably improved. Personally, I think such standards are worth promoting as they drive technological progress.
