ABSTRACT:
The present invention utilizes a single shaft with cam-actuated control valves and one linear solenoid for control of air flow control vales in the air induction system for a V-type engine. According to various exemplary embodiments of the present invention, the single shaft and one sensor are utilized to activate all control valves. Additionally, the present invention can also be used in in-line engines. Advantageously, the present invention utilizes one moving shaft and sensor to activate all control valves on both sides of the intake manifold without restricting air flow by locating the shaft in the middle of the manifold—lower housing. Further, the control valves are not attached with screws, thus eliminating a tolerance stack-up at assembly problem. The air induction sub-system can be manufactured with metals or plastic, or any combination thereof.
