What is the emission standard for cars from 2007?

[AugustFitz]

2007 cars are classified as either China II or China III emission standards. Below is an introduction to China V and China VI standards: 1. Meaning: The higher the number, the more environmentally friendly the vehicle's emissions are, indicating a later release date and stricter energy-saving and emission reduction requirements. 2. Pollution: China I has the highest pollution level, while China VI has the lowest, generally categorized by year. 3. Engine: The biggest difference between China V and China VI vehicles lies in the use of a more efficient three-way catalytic converter in China VI vehicles, enabling the engine's emissions to meet China VI standards. 4. Upgraded Version: The China VI emission standard is an upgraded version of the current China V standard, imposing stricter and more scientific requirements on vehicle tailpipe emissions.
