Abstract
An air induction system for an engine having an improved mechanism for control of an intake door. The system includes a housing having an opening for receiving intake air. A power activated door is pivotable between a closed position wherein the opening is closed and an open position wherein intake air may enter through the opening. Linkages operatively connect an actuator cylinder to the door. The linkages are configured such that movement of the cylinder produces a corresponding rotation of the door which is non-uniform across the cylinder's range of motion. The linkages include first and second bellcranks mounted for pivotal motion, and a link which interconnects the bellcranks. Movement of the cylinder at a first position causes pivoting of the door, while movement at a second position causes substantially no pivoting of the door.
