ABSTRACT:
An ECU controls an opening degree of an EGR gas switch valve based on a temperature of intake air and a load state of an engine in such a manner that a temperature of exhaust gas becomes a suitable temperature, which is suitable for regeneration of a particulate filter arranged in an exhaust gas passage. In this way, cooled EGR gas, which passes a main passage, and hot EGR gas, which passes a bypass passage, are appropriately mixed. In a case, where reliability of an EGR valve cannot be maintained, EGR cut is performed.
