置。 A primary side intake port and a secondary side intake port are formed in each cylinder of a multi-cylinder internal combustion engine using a dual carburetor, and each cylinder has an intake port in both the primary side intake port and the secondary side intake port. While providing a valve,
The primary side intake port is connected to the primary side carburetor of the dual type carburetor via the primary side intake passage, and the secondary side intake port is connected to the secondary side of the dual type carburetor via the secondary side intake passage. In an internal combustion engine, each of which is connected to a carburetor, the primary side intake passage is formed into an intake passage branching in a tournament shape toward the intake port of each cylinder, and the primary side intake passage is connected to the secondary side intake passage. Disposed on the bottom side of the passage, and
An intake system for an internal combustion engine, characterized in that a chamber for preheating the intake air is integrally formed on the lower surface of the primary side intake passage so as to extend from the gathering part for the primary side carburetor to the tournament-shaped branch part. .
