Investigation of a Turbulent Flame Propagation Model for Application for Combustion Prediction in the S.I. Engine 760758
This paper is a follow-up of the authors' earlier paper(1)* in which the development and evaluation of a mathematical model for turbulent flame propagation in the S.I. Engine had been described. The present paper gives a report of further studies regarding the general applicability of this model for S.I. engine combustion prediction. A simplified scheme has also been suggested to predict the pollutant emission by a correlation of the computed equilibrium mole fractions to the measured emission levels of ‘CO’ and ‘NOx’ in the exhaust. A wide variety of operating conditions has been considered and the model is applied in a simulation program to compute the combustion and exhaust emission characteristics for each operating condition. The predicted results, in general, are in conformity with the experimentally measured results reported in literature.
