摘要：To provide an improved heat insulating structure in which the movement of airin the air space of a heat insulating layer is permitted as small as possible thus giving ahigher heat shielding effect. A heat insulating layer of an air space is provided between acenter tube and an external heat shielding tube in a fuel injection nozzle and a carbongetter is disposed at an interface between the heat insulating layer and a combustionchamber. When a combustion gas moves into the carbon getter, its carbon componentsare trapped and accumulated thus blocking between the heat insulating layer and thecombustion chamber. As the heat insulating layer is isolated, its inside air remainsstagnate increasing the heat shielding effect. This srtacture has been appied to the pre-combustion chamber.
