What are China III vehicles?
1 Answers
China's National III emission standard was implemented on July 1, 2007, and the National IV standard replaced it on July 1, 2010, marking the end of the National III era. Generally speaking, vehicles produced between 2007 and 2010 comply with the National III standard. Relevant information about vehicle emission standards is as follows: 1. Introduction: Vehicle emission standards regulate the content of harmful gases emitted from vehicle exhaust, including CO (carbon monoxide), HC+NOx (hydrocarbons and nitrogen oxides), and PM (particulate matter, soot). 2. Implementation: Starting from January 1, 2004, Beijing upgraded its vehicle emission standards from Euro I to Euro II. By 2008, the Euro III standard was officially implemented.
