ABSTRACT:
An apparatus for applying a stratified charge to a reciprocating internal combustion engine is disclosed. The apparatus comprises a cylindrical rotary valve body disposed for rotation within the head of an internal combustion engine. The valve body defines diametrically extending inlet and exhaust passages which, during rotation of the valve body, place a cylinder of the engine in sequential communication with an inlet manifold and an exhaust manifold secured to the head. The inlet manifold comprises a double-passage gallery for transporting a lean fuel/air charge in a first passage and a rich fuel/air charge in a second passage. Rotation of the inlet passage into communication with the cylinder also brings the inlet passage into sequential communication with the first throat and then the second throat for transporting the first lean charge and then the second rich charge to the cylinder. Means are also provided for shielding the exhaust passages for excessive exhaust heat; for sealing the rotary valve body and for controlling the timing of the valve in response to engine demand.
