ABSTRACT:
An air intake system for internal combustion engine comprises a surge tank the inside of which is divided by a partition wall into two elongated parallel volumetric chambers. The surge tank has a portion extending beyond the branch tube that is located most remote from an air inlet in the tank. The partition wall of the surge tank extension is provided with an aperture for communicating the volumetric chambers with each other. The aperture is opened and closed by a butterfly valve operated by an actuator in response to engine operating conditions, to match the effective length of the intake system with an engine speed. In a preferred embodiment, the surge tank extension provided with the butterfly valve and the actuator forms a valve assembly which is separate from the remainder of the surge tank.
