Abstract
An internal combustion engine is provided with intake ports having transversely intersecting, longitudinally extending, wall defining cellular passages for intake flow. Selective control of both the location and volume of flow are provided by various means such as slidable entrance valves or an adjustable connecting manifold. In the latter case, movement of the manifold may variably control the flow of either air-fuel mixture or air through the various cellular passages in the respective intake ports.
Claims4
In an internal combustion engine having at least one cylinder with a closed end,
- an intake port through the cylinder closed end and extending from an entrance portion in an exterior wall of the engine to a valve seat adjacent an interior wall of the cylinder,
- cellular passage defining transversely intersecting walls extending longitudinally of the intake port from its entrance portion to adjacent said valve seat to direct inlet gas flow in a plurality of separate generally parallel cellular flow paths having transverse dimensions substantially less than those of the port and extending through predetermined portions along substantially the total length of the port, and
- adjustable valve means at the port entrance portion and movable to selectively open a desired number and grouping of said cellular flow paths whereby the amount and location of gas flow delivery to the cylinder is adjustably controlled.
In an internal combustion engine having at least one cylinder with a closed end,
- an intake port through the cylinder closed end and extending from an entrance portion in an exterior wall of the engine to a valve seat adjacent an interior wall of the cylinder,
- cellular passage defining walls extending longitudinally of the intake port from its entrance portion to adjacent said valve seat to direct inlet gas flow in a plurality of separate generally parallel cellular flow paths through predetermined portions of the port,
- a first source of fluid air-fuel mixture connectable with the intake port at said exterior wall
- a second source of supplemental inlet fluid connectable with the intake port at said exterior wall, and
- adjustable valve means at the port entrance portion and movable to selectively open to each of said first and second fluid sources a desired number and grouping of said cellular flow paths whereby the relative amount and location of gas flow delivery from said fluid sources to the cylinder is adjustably controlled.
