Patent ID: 7210444

Claim:
An air intake system for use in an internal combustion engine, comprising: an air box having an air inlet, an outlet, and an interior space; and a suction pipe in fluid communication with the outlet of the air box for supplying air to a cylinder head of the internal combustion engine, the air box having a tube in the interior space, the tube having a longitudinal central axis and being divided into at least a first and a second part, the first part being disposed on one side of the longitudinal central axis and the second part being disposed on the other side of the longitudinal central axis, the second part being selectively movable with respect to the first part between a first position in which the first part and the second part cooperate with the suction pipe to form an air passageway from the interior space towards the cylinder head, and a second position in which the second part does not cooperate with the suction pipe to form the air passageway from the interior space towards the cylinder head; and an inlet control device being operatively connected to the second part, the inlet control device cooperating with the inlet of the air box in response to the movement of the second part of the tube so as to restrict airflow into the airbox.
