焼室構造。[Claims for Utility Model Registration] (1) A coating layer is used on the surface of the combustion chamber, the thermal conductivity and volumetric specific heat of which is lower than that of the base material constituting the combustion chamber, and the thickness of the coating layer is equal to the combustion heat. As the supply progresses, the amount of heat transfer from the coating layer is affected by the thermal resistance from the coating layer to a greater extent than the temperature difference as a driving force for heat conduction in the increasing direction, and then the temperature increases. A combustion chamber structure for a rotary piston engine, characterized in that the difference is set to have a greater influence than the thermal resistance in the direction in which it increases. (2) The combustion chamber structure of a rotary piston engine according to claim 1, wherein the coating layer is formed of partially stabilized zirconia. (3) A combustion chamber structure for a rotary piston engine according to claim 2, wherein the coating layer has a thickness of 100 to 200 μm.
