EFFECTS OF TURBULENCE ON SPARK-IGNITION ENGINE COMBUSTION

The effects of mixture turbulence on combustion in a spark- ignition engine were investigated using a CFR engine. The apparent instantaneous turbulent flame speed during combustion was calculated from a combustion head release model that used measured cylinder pressures and assumed spherical flame propagation. This flame speed was correlated with turbulent intensities measured in the motored engine. The ratio of fully developed turbulent flame speed to laminar flame speed was found to be a linear function of motored turbulent intensity. /GMRL/
