気装置。 Two intake ports, a primary side intake port and a secondary side intake port, are formed in each cylinder of a three-cylinder internal combustion engine using a dual carburetor, and the primary side intake port and the secondary side intake port are connected to each other. An intake valve is provided in both of the cylinders, and the primary side intake port of each cylinder is connected to the primary side carburetor of the dual carburetor via the primary side intake passage, and the secondary side intake port of each cylinder is connected to the secondary side intake port of the dual carburetor. In an in-line three-cylinder internal combustion engine, each of which is connected to a secondary side carburetor in the dual carburetor via a side intake passage, a first cylinder located outside a central second cylinder among the three cylinders; The primary side intake ports of the cylinder and the third cylinder are arranged at positions that are shifted away from the center of the first cylinder and the third cylinder in a direction further away from the center of the second cylinder,
The dual carburetor is located at a position substantially right next to the second cylinder in the center, and the primary side carburetor in the dual carburetor is connected to the primary port in each of the first and third cylinders. An intake system for an in-line three-cylinder internal combustion engine, characterized in that both primary side intake passages are formed in an inclined V-shape that widens toward the engine when viewed from above.
