  • Patent number: 9038592
    Abstract: Disclosed is an engine that comprises an engine block, and the engine block comprises a cylinder. The engine further comprises a cylinder head mounted to the engine block, and the cylinder head comprises an intake valve seat and a shroud. Further yet, the engine comprises a combustion chamber formed at least partially by the cylinder and the cylinder head. The intake valve is configured to travel between a fully closed position seated against the intake valve seat and an opened position displaced from the intake valve seat, thus allowing intake flow through the intake valve seat into the combustion chamber. The shroud only partially surrounds a periphery of the valve and extends along at least a portion of the travel of the intake valve so as to restrict intake flow along only a portion of the intake valve.
