Abstract: The work contains elements of combustion stoichiometry. It defines the ratio of the mass of the fuel mc and air mass ma, called fuel-air dose, d. Commercial liquid fuels for engines of petroleum origin, as natural gas is generally complex mixtures of hydrocarbons and other organic substances. For the calculation of combustion air and combustion products is consider a pure substance considered as representative of a particular class of commercial fuels. Can be represented by octane gasoline (C8H18), diesel with cetane (C16H34), or dodecanese (C12H26), natural gas by methane (CH4). Corresponding quantities of products are ? ?CO2 , ?CO ? ?H2O , ? ?H2 , mol/mol fuel. Tfa adiabatic flame temperature is determined by solving the equation vp ?[hp(Tp) ? hp(Ts)??vr ?[hr(Tr) ? hr(Ts)? ?Qps ? 0.

Keywords: Stoichiometric combustion, Thermodynamics.
