An enhanced engineering version of the Los Alamos National Laboratory's Kiva 3 code, called CRI/Turbokiva 2.0, was applied to the study of the mean and turbulent flow field evolution during compression and combustion in a spark ignition engine. A kinetically influenced turbulent combustion model was formulated to overcome the limitations of the standard turbulent combustion model. Mean velocity, turbulence intensity and turbulent length scale results are presented and compared with experimental data, providing satisfactory agreement. These comparisons provide a proper validation work for the fluid dynamic and combustion parts of the code.
