Engine with variable flow controlled cellular intake port

Claim 2

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.

Claim 3

The combination of claim 1 wherein said adjustable valve means is operative to selectively block off those of the cellular flow paths of its respective port which are not selectively opened in any particular position setting of the valve means.

Claim 4

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.

Claim 5

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.

Claim 6

The combination of claim 3 wherein said valve means comprises an intake conduit connected internally with said first fluid source and having a chamber surrounding said port connected with said second fluid source, said conduit having an outlet end slidable along said engine exterior wall into greater and lesser register with the intake port to vary the portion of the port connected with the first and second fluid sources.
