Abstract: An intake manifold for a four-cycle internal combustion engine with multiple stages to reduce imbalances in volumetric efficiency and air/fuel ratio. The intake manifold utilizes at least two ram stages coupled by a plenum chamber. The first stage includes a ram tube that carries the air/fuel mixture from the carburetor, or throttle body to the plenum chamber. The second stage includes at least two ram tubes that carry the air/fuel mixture from the plenum to a plurality of intake valves through cylinder head intake ports. The plenum chamber acts as a buffer between each intake valve and the carburetor or throttle body. The air/fuel mixture enters the first stage ram tube and passes into the plenum chamber. These gases then pass into either one of the second stage ram tubes, depending on which cylinder is at its intake stroke. By drawing the air/fuel mixture from the plenum instead of directly from the first stage ram tube, differences in the air/fuel ratio and volumetric efficiency are minimized.

Abstract: A cylinder head for a four-cycle internal combustion engine with improved intake port and combustion chamber configuration. The physical shape of the intake port and combustion chamber directs the flow of the incoming air/fuel mixture in a swirl path, which is directed toward the spark plug. In particular, the intake port has a fin at its terminal opening into the combustion chamber. The fin creates a swirling motion in the incoming gasses and also directs the flow of the gasses toward the spark plug. As a result, a greater percentage of the intake charge is in close proximity to the center of the combustion chamber and the spark plug, and hence combustion occurs faster and more completely. In a preferred embodiment of the invention, the portion of the cylinder head that forms the upper surface of the combustion chamber, includes a shear ledge that further acts to direct the flow of the incoming gasses toward the sparkplug.
