Combustion Temperature, Pressure, and Products at Chemical Equilibrium

For the computation of the equilibrium combustion temperature and pressure of hydrocarbon fuel in air, an original set of eighteen equations is enlarged by the energy and mass balance, and the procedure is applied to the cases of constant volume and of constant pressure combustion. Examples of engine combustion, including the effects of air-fuel ratio and the effect of water injection or exhaust gas recirculation, are treated; the results of computation are presented in graphs. The procedure of transformation and coding of the equation system for the solution on an electronic computer is described.
