| 摘要 |
The present invention makes it possible to extend the lifespan of a reforming catalyst without having to detect a performance decrease/degradation of the reforming catalyst. The present invention is an internal combustion engine system comprising : an internal combustion engine (10) in which an exhaust circulation path (30) is connected to an exhaust path (13) and an intake path (12) communicating with a combustion chamber (11); a reforming fuel injection device (33) for injecting a reforming fuel into an exhaust gas flowing through the exhaust circulation path (30); and a reformer (32) provided with a reforming catalyst for generating a hydrogen-containing gas using the reforming fuel; wherein the internal combustion engine system is provided with a reforming catalyst regeneration means (C3) for causing an oxygen-containing gas to flow through the exhaust circulation path and thereby regenerate the reforming catalyst every predetermined timing for regenerating the reforming catalyst. |
