  "term": "Fuel Stoichiometric Ratio",
  "field": "Environment",
  "definition": "1. Relating to the particular ratio of air and fuel such that if the fuel were fully oxidized, there would be no remaining fuel or oxygen. For example, stoichiometric combustion in a gasoline-fueled engine typically occurs at an air-to-fuel mass ratio of about 14.7:1. [40 CFR 1045.801 (CFR 2013)]\n\n2. Relating to the particular ratio of air and fuel such that if the fuel were fully oxidized, there would be no remaining fuel or oxygen. For example, stoichiometric combustion in a gasoline-fueled engine typically occurs at an air-fuel mass ratio of about 14.7.\n\n3. Theoretical air-to-fuel ratio required for complete combustion.",
