構造。 In the intake manifold structure in which the outlet passage of the exhaust gas recirculation passage is formed in the riser part, a bulge is formed in the riser part in the longitudinal direction of the intake manifold, and a tip is formed inside the bulge. An internal combustion engine characterized in that the outlet passage is formed in a downwardly sloping shape, and is formed by cutting out both sides of the bulge so that the tip end opening of the outlet passage is oriented in the left and right branch directions. intake manifold structure.
