第１項記載の内燃機関の吸気加熱装置。[Scope of Claim for Utility Model Registration] 1. In an intake system for an internal combustion engine in which a swirl control valve is installed in the intake port and the swirl control valve is closed in the low and medium load range of the engine to generate swirl in the combustion chamber, An intake passage leading to the port is branched into a large-diameter main intake passage and a small-diameter bypass passage on the upstream side of the swirl control valve, and an intake air heating device is attached to the bypass passage,
At a branch point between the main intake passage and the bypass passage, the main intake passage is closed and the bypass passage is opened in a low and medium load range of the engine, and the main intake passage is opened and the bypass passage is opened in a high engine load range. An intake system for an internal combustion engine, characterized in that it is provided with a switching control valve that closes. 2. The intake air heating device for an internal combustion engine according to claim 1, wherein the heating device is constituted by an exhaust passage on the downstream side of a catalytic converter.
