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 The other is administrative measures, including scrapping and renewing old vehicles, phasing out outdated cars, developing new types of vehicles (i.e., motor vehicles with no pollutant emissions), and controlling fuel usage standards.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.
