ABSTRACT:
A rotary valve device for internal-combustion engines, said device comprising an elongated, tubular drum having an exhaust-manifold system disposed therein and a plurality of fuel passages, forming a fuel-intake system having fuel-intake ports and fuel-outlet ports positioned in the peripheral wall of the drum, whereby lean and rich fuel mixtures can be separately but simultaneously deposited in each combustion chamber of an internal-combustion engine, as the tubular drum rotates within the cylinder head, so that a complete burning of the fuel takes place. A cooling means, such as a water jacket, is interposed between the inner, tubular, manifold-exhaust conduit and the fuel passages -- the jacket being provided with openings at the terminating ends thereof for connecting the water flow to the cooling system of a conventional-type engine.
