Abstract
In a reforming driving mode, while the EGR valve is opened to recirculate a part of exhaust gas into the intake pipe, a reforming-fuel injector injects a reforming-fuel into an exhaust gas flowing through an EGR pipe. The injected reforming-fuel is vaporized and flows into the fuel-reforming catalyst. The fuel-reforming catalyst reforms the fuel in the exhaust gas into the fuel having high combustibility. In the reforming driving mode, the computer determines whether an air-fuel ratio within the normal range. Based on this result, the computer determines whether the reforming-fuel injector has a malfunction. When the reforming-fuel injector has a malfunction, a fail-safe processing is conducted to prohibit the reforming-fuel injector from injecting the reforming-fuel.
