ド。A dual port exhaust system for a 4-cylinder internal combustion engine in which a branch pipe that connects to the 1st cylinder and the 4th cylinder, and a branch pipe that connects to the 2nd cylinder and the 3rd cylinder respectively come together to form two collecting pipes. In the manifold, a secondary air port is provided on the upstream side of each branch pipe connected to the first cylinder and the fourth cylinder, and a bypass exhaust circuit is separated on the upstream side of the secondary air port. The exhaust circuit is assembled into a collection pipe of branch pipes connected to the second cylinder and the third cylinder, respectively, and a separation wall is installed inside the collection part to separate the second cylinder and the third cylinder.
1. An exhaust manifold for an internal combustion engine, characterized in that a bypass exhaust boat of branch pipes connected to each cylinder is formed, and a detector for exhaust gas analysis is inserted in the collecting part.
