Abstract

The thickness of the burning zone and the turbulent burning velocity in the cylinder of the spark-ignition engine were compared with those in constant volume vessels of the disk and cubic types. As a result, it was found that the thickness of the burning zone had a good correlation with the value of the relative burning velocity which was the turbulent burning velocity divided by the laminar burning velocity, under various conditions of fuel (propane and methane), equivalence ratio (0.8~1.4), pressure (atmospheric pressure~1.6 MPa) and unburned gas temperature (300~620 K). Moreover, the turbulent flame in the burning zone could be considered to be the burning of islands based on the discussion of the relationship between the Reynolds number and the Damköhler number in this engine except for conditions of very weak turbulence.
