Abstract

An EGR channel and an EGR valve are provided for introducing EGR gas into an intake channel upstream of a compressor that supercharges intake air. There is provided an intake bypass channel that connects the intake channel downstream of the compressor and the EGR channel immediately downstream the EGR valve along the direction of the flow of the EGR gas to each other, and a bypass valve capable of selecting a configuration of an intake air flow channel from among a first channel in which the intake air having passed through the compressor passes through the intake channel and flows into a cylinder and a second channel in which in the state where the EGR valve is closed, part of the intake air having passed through the compressor passes through the intake bypass channel and the EGR channel and is recirculated to a part upstream of the compressor.
