It is necessary to estimate the turbulent burning velocity in the cylinder of a spark-ignition engine, in order to refine the entrainment model which is often used for modeling engine combustion. Nevertheless, the effect of turbulence characteristics on the burning velocity has scarcely been studied in a spark-ignition engine. We have investigated those in constant volume vessels of disc and cubic types. In this study, the turbulent burning velocity, S_T, and the thickness of the burning zone, δ_T, were determined in a spark-ignition engine cylinder. As a result, it was made clear that S_T and δ_T increased with increasing turbulence intensity, and that δ_T Was correlated linearly with S_T except under the condition of weak turbulence.
