Understanding 尾气 (wěiqì)
尾气 literally means 'tail gas' and refers to exhaust gases emitted from vehicles or industrial sources. It is a key term in environmental discussions, especially concerning air pollution caused by automobiles and factories.
Usage in Context
尾气 is commonly used when talking about pollution control, environmental policies, and vehicle inspections. For example, phrases like 尾气排放 (exhaust emissions) and 尾气检测 (exhaust testing) are frequent collocations.
Common Collocations
- 尾气排放: exhaust emissions, used when discussing pollution levels or regulations.
- 尾气检测: exhaust testing, often mentioned in vehicle inspections.

Notes
尾气 is a neutral term but often appears in negative contexts due to its association with pollution. It is important not to confuse 尾气 with 气 (air or gas) alone, as 尾气 specifically refers to emitted exhaust gases. When discussing air quality, 尾气 is a precise term for vehicle or industrial exhaust rather than general air or gas.
