Intake system for multicylinder internal combustion engine

摘要

A surge tank construction arranged in an intake system of a multicylinder internal combustion engine, the surge tank defining an expansion chamber having faced first and second inner walls. A tubular body in which a throttle valve is arranged is open to the expansion chamber at the first wall. A partition wall extends from the second wall toward the first wall and terminates at a position spaced therefrom so that portions of the expansion chamber divided by the partition wall and connected to the respective groups of cylinders are connected to each other.
