For global environmental improvement, it is necessary to promote the efficiency of an internal combustion engine. Introduction of the gas flow is performed positively to improve the combustion characteristics in an internal combustion engine. However, combustion is promoted thereby, but it does not always lead to improve the thermal efficiency from the viewpoint of heat loss. Therefore it is necessary to be investigated how influences the gas flow in an engine gives to heat transmission to a wall surface. In this study, it is investigated how influences the gas flow after the combustion end gives to heat transmission with constant volume vessel which is modeled an engine .In the constant volume vessel, the swirl gas is generated by opening and shutting of a valve, and ignited. When the combustion ended, the flow velocity and heat flux were measured for 0.4s. As the results, the heat transfer coefficient of the circumference wall was higher than the outer flat walls.
