Guenther, W D

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 first and second inlet ports and an exhaust port. The first inlet port is disposed, upon rotation in the valve body, to establish communication between an intake manifold for transporting a fuel lean charge and a main combustion chamber of the engine. The second inlet port is disposed for establishing simultaneous communication between a second manifold for transporting a fuel-rich charge and a pre-combustion chamber adjacent the main combustion chamber. The exhaust valve is disposed for establishing communication between an exhaust manifold and the main combustion chamber. In a second embodiment of the invention, the inlet passages and the exhaust passages are located in separate valve bodies mounted for rotation within the head. Means are also provided for shielding the exhaust passages from excessive exhaust heat, for sealing the rotary valve body and for controlling the timing of the valve in response to engine demand.
