It is necessary to promote the efficiency of the internal combustion engine to a global environmental improvement. The gas flow is used to promote the combustion of the internal combustion engine. However, it cannot be asserted that the improvement of thermal efficiency is promoted by introducing the gas flow. Then, it is necessary to clarify the interrelation between the gas flow in the cylinder and the heat transfer for the thermal efficiency improvement of the internal combustion engine. In this study, how influences the gas flow after the combustion end gives to heat transmission to the wall of the constant volume vessel which is modeled an engine. In the constant volume vessel, the swirl gas is generated by using the shroud valve, and ignited. When combustion ended, flow velocity and the heat flux were measured for 0.4s. The heat fluxes of inside and outside surroundings wall of the vessel and the upper and the lower walls are compared, respectively. As the results, it was understood that the heat flux is not influenced the shape nor position of the wall.
