空燃比 Air–fuel ratio
（重定向自Equivalence ratio）
空燃比（Air-fuel ratio，简称AFR）是指在内燃机中，空气与燃料的质量比。如果它恰好等于能使得燃料完全燃烧的化学计量比，则称为化学计量空燃比。空燃比是减少排放和提高内燃机性能的一个非常重要的参数。

Air–fuel ratio 空燃比
（重定向自Equivalence ratio）
Air–fuel ratio (AFR) is the mass ratio of air to fuel present in a combustion process such as in an internal combustion engine or industrial furnace. The AFR is an important measure for anti-pollution and performance-tuning reasons.
If exactly enough air is provided to completely burn all of the fuel, the ratio is known as the stoichiometric mixture, often abbreviated to stoich.
