ON THE PROBLEM OF PREDICTING BURNING RATES IN A SPARK IGNITION ENGINE

Formulation of a mathematical model for flame propagation in a spark ignited reciprocating engine has been described. The laminar burning velocity is calculated from Semenov's thermal model for the instantaneous unburned gas condition during combustion and is augmented for engine gas turbulence through an empirical function of the engine Reynolds parameter assuming wrinkled flame model. The turbulent flame velocity thus obtained is then corrected for flame transportation due to the expansion of the burning gases. /GMRL/
