What is the emission standard for cars in 2011?
2 Answers
2011 cars belong to the National IV emission standard, which is the fourth stage of China's national standards for motor vehicle pollutant emissions. Below is the timeline of China's vehicle emission standards: 1. National I: GB18352.1-2001 'Limits and Measurement Methods for Emissions from Light-Duty Vehicles (I)', equivalent to EU Directive 93/59/EC, partially adopting technical content from 98/77/EC, equivalent to Euro I, implemented on April 16, 2001. 2. National II: GB18352.2—2001 'Limits and Measurement Methods for Emissions from Light-Duty Vehicles (Ⅱ)', equivalent to EU Directive 96⑽69/EC, partially adopting technical content from 98⑽77⑽EC, equivalent to Euro II, implemented on July 1, 2004. 3. National III: GB18352.3Ⅻ2005 'Limits and Measurement Methods for Emissions from Light-Duty Vehicles (China III, IV stages)', partially equivalent to Euro III, implemented in 2007. 4. National IV: Partially equivalent to Euro IV, implemented in 2010. 5. National V: GB18352.5-2013 'Limits and Measurement Methods for Emissions from Light-Duty Vehicles (China V stage)', implemented on January 1, 2018.
I've driven several cars from 2011, when emission standards were the top concern for car buyers. I remember the salesperson telling me that most new cars in 2011 met China IV standards, as China had fully implemented the China IV emission standards nationwide in July 2010. From then on, newly produced gasoline vehicles had to meet stricter limits, such as reducing carbon monoxide and nitrogen oxide emissions. This was beneficial for air purification, and many major cities promoted China IV fuel. If your car was manufactured in 2011, it's most likely China IV, though a few imported or special models might differ. When my friend sold his 2011 used car last year, he was even required to show the emission label, and confirming the standard helped fetch a slightly higher resale price. Looking back now, China IV was an important milestone in the evolution of emission standards, driving the development of cleaner technologies that followed.
