Abstract:
An EGR device for an internal combustion engine comprises: an EGR path through which a part of exhaust gas is recirculated from the exhaust gas conduit of an internal combustion engine as EGR gas to the intake path; and an EGR valve that is disposed within the EGR path and adjusts the flow rate of the EGR gas flowing through the EGR path. An curved structure EGR path from a position at which the EGR valve is disposed until a joining section (8d) merging with an intake manifold is a curved structure having a turned-back section which is curved in a cross-sectional view cutting a plane parallel to an installation plane on which the internal combustion engine is mounted. The position at which the EGR valve is disposed is higher than the joining section, and the EGR path of the curved structure slopes downward from the EGR valve side.
