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.

Air/fuel induction system for developing swirl motion of an air/fuel mixture

A throttle for an internal combustion engine wherein intake runners (18) include slots (24) through which a slide throttle plate (26) is mounted. The throttle plate includes openings (28) selectively aligned with the runners (18) by an actuator (32) to control the air flow into the engine intake ports (14). Actuation back and forth across the runners (18) can provide for flow control as well as port deactivation, while a throttle plate (226) configured for up and down motion relative to the intake runners (218) can provide for tumble port flow control.

A throttle for an internal combustion engine wherein intake runners (18) include slots (24) through which a slide throttle plate (26) is mounted. The throttle plate includes openings (28) selectively aligned with the runners (18) by an actuator (32) to control the air flow into the engine intake ports (14). Actuation linearly across the runners (18) provides for tumble port flow control and idle control, as well as port deactivation.
