What is the equivalent of Euro 3 standard in China's national standards?
2 Answers
Euro 3 emission standard is equivalent to China's National III emission standard. Generally, most new private cars produced between 2005 and 2010 were set with Euro 3 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. The nationwide implementation date in China was July 1, 2007. Below is an introduction to the National III standard: 1. According to Announcement No. 5 of 2006 by the State Environmental Protection Administration, 'Announcement on the Release of New Motor Vehicle Models and Engine Types Meeting the National Phase II and Phase III Emission Limits for Motor Vehicles,' the National III standard mainly applies to light gasoline and diesel vehicles under 3.5 tons, equivalent to the Euro III standard. The nationwide implementation date in China was July 1, 2007. 2. The National III standard represents a significant improvement, primarily emphasizing the 7-degree emission standard for motor vehicles, which is not found abroad. Another key feature is the zero-start standard for motor vehicles, including OBD (On-Board Diagnostics). Throughout the vehicle's usage, if any emission-related issues arise, the vehicle will automatically issue an alert, prompting the owner to visit a service station for repairs to resolve the problem.
As an automotive technology enthusiast, I'm familiar with the evolution of emission standards. The Euro 3 standard was implemented in Europe around 2000, setting limits for nitrogen oxides, particulate matter, etc. Its Chinese counterpart is the National 3 standard, which essentially adopted Euro 3's emission requirements, so they can be considered roughly equivalent. For specific vehicles, imported Euro 3-compliant cars would be classified as National 3 level in China. However, in practice, when National 3 was introduced around 2007, it accounted for local fuel differences and road condition testing. Currently, many major cities impose driving restrictions on National 3 and below vehicles, such as Shanghai and Beijing banning them from inner ring roads. Upgrading to National 4 or higher standards can reduce pollution and avoid policy restrictions.
