の吸気装置。In a spark-ignition internal combustion engine in which an ignition plug is installed inside a combustion chamber that has an intake pot into which intake air is introduced through a main intake passage, a valve stem portion of an intake valve that opens and closes the intake port and this valve stem portion are used. An auxiliary intake passage is formed between the auxiliary intake passage and the valve guide that is slidably held, and an air introduction passage is provided that bypasses the intake port and communicates the auxiliary intake passage with the main intake passage upstream of the throttle valve. A heat exchange part for heating the intake air is provided in the middle of the valve guide, and a jet port for jetting the intake air from the auxiliary intake passage toward the combustion chamber is formed in the valve guide, and the jet port is synchronously operated with the intake valve to direct the engine's intake air. An intake device for a spark-ignition internal combustion engine, characterized in that a valve body that opens during stroke is integrally formed in a valve stem portion.
