Abstract
Air flow from the airbox (57) to the carburetor of an internal combustion engine is regulated by a plurality of valve bodies (66) fitted with rotatable lids (77) which permit infinite adjustment of air flow between a fully closed and fully open position. In an alternate embodiment, a rectangular valve is used that has a relatively lower profile and uses a sliding door (94) to permit manual adjustment of airflow to the airbox (57).
Claims7
A system for regulating air flow to an internal combustion engine having an induction system that includes an air box, comprising:
- a valve body, the valve body being affixed to the air box so as to permit atmospheric air to be directed through the valve body into an interior region of the air box, the valve body being formed as a truncated cone, the truncated cone comprising:
- a first discontinuous sidewall;
- and
- a first longitudinal axis;
- and
- a valve lid, the valve lid being movably affixed to the valve body so as to define dimensions of an opening within the valve body through which the atmospheric air passes, the valve lid is formed as a truncated cone comprising:
- a second discontinuous sidewall;
- and
- a second longitudinal axis, the valve lid being mounted over the valve body such that the first and second longitudinal axes are collinear, the valve lid being rotatable about the second longitudinal axis.
A system for regulating air flow to an internal combustion engine having an induction system that includes an air box, comprising:
- a valve body, the valve body being affixed to the air box so as to permit atmospheric air to be directed through the valve body into an interior region of the air box, the valve body being formed as a longitudinally extending tray, the tray having a discontinuous bottom surface;
- a valve lid, the valve lid being movably affixed to the valve body so as to define dimensions of an opening within the valve body through which the atmospheric air passes;
- and
- at least one door member, the door member being slidably mounted to the tray so as to regulate air flow through the discontinuous bottom surface.
