Abstract

In a pentroof type combustion chamber of spark-ignition engine, a tumbling flow is broken down to small scale eddies near the top dead center in compression stroke and promotes the flame propagation. The effects of tumbling flow and its turbulence on combustion were investigated by analyzing combustion pressure and ion-current wave form. The number of peaks of ion-current wave N̄p increases with the increase in turbulence intensity. The mean rate of heat release in the early stage of combustion increases linearly with the increase of N̄p The spacing of flamelet surfaces in burning zone of turbulent flame decreases with the increase in turbulence intensity.
