Abstract
An air/fuel mixture induction system for an internal combustion engine having a pair of intake valves, an intake air/fuel mixture flow passage communicating with each valve, a primary mask surrounding a portion of the perimeter of one of the intake valves, the air/fuel mixture being directed from the intake valve over the remaining peripheral portion thereof, thereby establishing a swirl motion in the combustion chamber, a secondary bridge mask partially surrounding the other of the pair of intake valves, the secondary bridge mask having an air/fuel mixture flow controlling surface that directs the swirl motion of the air/fuel mixture in the direction of the axis of the cylinder whereby swirl motion progresses in the direction of the axis of the cylinder throughout the combustion chamber.
