Stoichiometric Concentration (Cst) The ratio of moles of fuel to moles of fuel-air mixture required to get complete oxidation of the fuel to carbon dioxide (CO2) and water (H2O) with no excess oxygen in the products. The values given in Kuchta are as a percentage of fuel in the mixture of fuel and air. Note that these values are identical for volume, molar, and partial pressure basis for gaseous fuels.
