装置。[Scope of Claim for Utility Model Registration] 1. A catalyst case filled with a porous fuel reforming catalyst is installed in the exhaust pipe of an internal combustion engine, and the upstream end and downstream end of the case are respectively installed in the exhaust pipe. The openings are closed so that exhaust gas can flow into the case from either opening, and an injector is installed approximately in the middle area of the case to supply fuel into the case, which connects the engine intake system. The upstream side of the case is connected to the upstream side of the case by a conduit, and the conduit is provided with a control valve that opens when the engine is under low and medium load and closes when the engine is under high load, and the upstream opening of the case is normally closed. The valve does not open regularly for a certain period of time when the engine is under high load. With this, when the valve is closed, exhaust gas is introduced into the case from the downstream side opening of the case and a mixture of exhaust gas and reformed fuel is added to the engine intake system, and when the valve is opened, the exhaust gas is introduced into the case from the downstream side opening of the case, and when the valve is opened, the exhaust gas is introduced into the case from the downstream side opening of the case. A reformed fuel supply device for an internal combustion engine in which a reforming catalyst can be regenerated, characterized in that the reforming catalyst can be regenerated by being introduced into an exhaust gas case from a side opening. 2. The reformed fuel supply system according to claim 1, wherein the control valve is an exhaust gas recirculation control valve. -3 The reformed fuel supply device according to claim 1, wherein a downstream portion of the case is filled with a fuel adsorbent.
