What does China 5 refer to in automobiles?
2 Answers
China 5 refers to the National Fifth Stage Emission Standard for motor vehicle pollutants, which is equivalent to the Euro 5 emission standard currently implemented in Europe. Compared to the China 4 standard, the China 5 standard reduces nitrogen oxide emissions by 25% for light-duty vehicles and 43% for heavy-duty vehicles. After the implementation of the China 5 emission standard, vehicle pollutant emissions will be significantly reduced, and vehicles meeting the China 2 emission standard will be mandatorily scrapped. For environmental protection, China has now promulgated the China 6 emission standard, which is divided into two phases: China 6a and China 6b. Compared to the China 5 standard, the China 6 standard imposes stricter controls on vehicle exhaust emissions.
China's National 5 (abbreviated as China V) refers to the fifth-stage emission standard established by our country, primarily regulating pollution control for newly manufactured vehicles. According to researched data, this standard was implemented nationwide in 2017, requiring vehicles to be equipped with more advanced three-way catalytic converters. The emissions of pollutants such as carbon monoxide and hydrocarbons must be reduced by over 40% compared to the National 4 standard. Data from the Ministry of Environmental Protection indicates that China 5 can reduce annual pollutant emissions by more than one ton per vehicle. The increased blue skies in cities like Beijing and Shanghai in recent years can partly be attributed to this standard. If you purchased a car in the past few years, checking the accompanying green environmental label marked with 'China V' confirms compliance with this standard.
