  • Patent number: 10267259
    Abstract: To improve fuel efficiency, some gasoline engines are equipped with valve deactivators in some of the cylinders so that at low torque conditions only a subset of the total number of cylinders are active. In prior art engines, particularly when they have four valves per cylinder, space is tight. It is known to provide a cam carrier in the head between the cylinder head and the camshaft. The cylinder head bolts pass through the head under the cam carrier. According to the present disclosure, the cam carrier, and its associated disadvantages, is obviated by widening the bearings for the camshafts, using smaller diameter head bolts, and putting the orifices for the head bolts directly through the bearings.

  • 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.
