Abstract
An exhaust for an internal combustion engine includes an exhaust valve rotating within the cylinder block to communicate with successive cylinders. An exhaust conduit rotates with the valve and is of smaller diameter than the valve. Combustion products are initially exhausted thorugh the conduit to attain high velocity. Continued rotation of the valve closes the duct and directs combustion products through the valve. The conduit terminates within the valve to induce flow of gas through the valve.
Claims14
A reciprocating piston internal combustion engine having a plurality of pistons each in respective cylinders disposed about an exhaust valve assembly, said valve assembly including an exhaust duct communicating through respective exhaust ports with said cylinders and an exhaust conduit located within said duct and rotatable relative to said cylinders, said conduit having a conduit inlet alignable with successive ones of said exhaust ports as said conduit rotates to allow communication therewith and a conduit outlet located within said duct, said conduit having a lesser cross sectional area than said duct whereby the velocity of exhaust gas in said conduit is higher than in said duct and, upon ejection from said conduit outlet, while said conduit is in communication with an advanced cylinder, induces flow through said duct from a preceding cylinder communicating with said duct.
