What is the Chinese equivalent of Euro III standard?

Euro III emission standard is equivalent to China's National III emission standard. Here is an extended introduction: 1. Introduction to National III: Most private cars manufactured between 2005-2010 were set with Euro III or National III emission standards for tailpipe emissions. The National III standard mainly applies to light gasoline and diesel vehicles under 3.5 tons, equivalent to the Euro III standard. Its nationwide implementation date was July 1, 2007. 2. Introduction to Euro III: The EU's emission standards are implemented through the emission regulations of the European Economic Commission (ECE) and the emission directives of the European Economic Community (EEC), where EEC is now the EU (European Union). ECE emission regulations are voluntarily recognized by participating countries, while EEC/EU emission directives are mandatory for member states.
The Euro III standard is equivalent to China's National III emission standard. I experienced the standard upgrade phase and remember that Europe implemented Euro III around 2000, while China introduced National III around 2005. The automotive industry underwent significant changes during this period, such as the strengthening of exhaust treatment systems and the widespread adoption of catalytic converters, which significantly reduced harmful emissions and improved urban air quality. At that time, new vehicle models emitted fewer pollutants like nitrogen oxides and hydrocarbons, contributing to environmental protection. However, older National III vehicles may now fail to meet the latest annual inspection standards or even face restrictions in certain areas. Maintenance requires more attention, such as regular checks of engine systems and sensors. The progress in emission control has driven technological innovation and is also an important step toward green mobility.
The Euro III standard basically corresponds to China's National III emission standards. As a car enthusiast, I've researched that Europe introduced Euro III in 2000, while China followed with National III in 2005. New vehicles after this saw optimized emissions, benefiting air quality significantly—for example, by limiting particulate matter and reducing smog risks. Now, with the stricter National VI standards, National III vehicles still exist but affect annual inspections. It's advisable to pay attention to the OBD system during maintenance to reduce malfunctions. Keeping the vehicle in good condition makes it more worry-free and holds great environmental significance, making it worth promoting vehicle updates.
