  "id": "MLC-T-MET-010359",
  "term": "Air-fuel ratio",
  "field": "Meteorology and atmospheric science",
  "definition": "The mass ratio of air to fuel present in a combustion process, a key parameter in determining the emissions from sources of air pollution. This ratio affects combustion efficiency and the chemical composition of the exhaust, influencing the production of pollutants like nitrogen oxides, carbon monoxide, and unburned hydrocarbons. The ideal or stoichiometric ratio varies depending on the specific fuel being burned.",
