関の吸−吸　気装置。a first throttle valve that is interposed in a gathering part of a main intake ventilation intake manifold consisting of branch pipes of an air manifold communicating with each intake port of the syringe head and controls the intake cylinder amount;
In an intake system for a multi-air combustion engine in which each cylinder has a second throttle valve connected to a first throttle installed near the intake port and which controls the flow direction of intake air, each of the second throttle valves is arranged in the direction of the cylinder row. When integrally interlocking with each other by a through-shaft extending from the cylinder head to the intake manifold, this through-shaft is supported in a groove formed long in the direction of the cylinder row on either side of the joint surface between the cylinder head and the intake manifold to prevent exposure to the atmosphere. An intake-intake system for a multi-cylinder internal combustion engine characterized by:
