Abstract: Disclosed is apparatus for actuating one or more latching arrangements of one or more respective rocker arms of a valve train assembly of an internal combustion engine. The apparatus comprises a shaft rotatable by an actuation source, one or more selector cams rotatable by the shaft, and a return apparatus. When the shaft is rotated from a rest orientation in a first direction or a second opposite direction, a biasing means contacts one or more radial protrusions of the shaft so as to bias the shaft rotationally in the second direction or the first direction, respectively, to towards a rest orientation.

Abstract: A rocker arm assembly comprises an outer arm assembly comprising a pair of opposed outer arms joined by an outer arm body and joined by a shelf. Each of the pair of opposed outer arms further comprises exterior posts extending out from the outer arm assembly. An inner arm assembly is nested in the outer arm assembly and comprises a pair of opposed inner arms. A latch shelf joins the opposed inner arms. An axle passage is through the opposed inner arms. Respective extensions extend outward from the nested inner arm assembly to selectively abut the shelf joined to the outer arm assembly. A respective pair of springs are coiled on respective exterior posts. The springs are biased to separate the shelf from the respective extensions. A main axle is connected between the opposed outer arms and is connected through the axle passage.

Abstract: A multiple-cylinder diesel engine system comprises an intake valve and an exhaust valve for each of the multiple cylinders. A valve control system is connected to selectively deactivate an intake valve and an exhaust valve for a selected cylinder. A fuel injection control system is connected to selectively deactivate fuel injection to the selected cylinder while increasing fuel to firing cylinders. The multiple cylinder diesel engine enters a cylinder deactivation mode whereby the valve control system deactivates the intake valve and the exhaust valve and the fuel injection control system deactivates the fuel injection to the cylinder while continuing to fire other cylinders of the multiple cylinder diesel engine. The valve control system selectively opens the deactivated intake valve to relieve a negative pressure condition in the deactivated cylinder. Alternatively, the valve control system opens the deactivated exhaust valve to relieve a negative pressure condition in the deactivated cylinder.

Abstract: A valvetrain for an internal combustion engine of the type that has a combustion chamber, a moveable valve having a seat formed in the combustion chamber, and a camshaft includes a rocker arm assembly, a pivot providing a fulcrum for a rocker arm of the rocker arm assembly, and a latch assembly. An electrical device mounted to the rocker arm assembly receives power or communicates through a circuit that includes an electrical connection formed by abutment between surfaces of two distinct parts. The rocker arm assembly is operative to move one of the two abutting surfaces relative to the other in response to actuation of the cam follower. Forming an electrical connection through abutting surfaces that are free to undergo relative motion may reduce or eliminate the need to run wires to a mobile portion of the rocker arm assembly.

Abstract: A novel cylinder head arrangement is described for an in-line four cylinder or eight cylinder engine with each head having two end cylinders and two middle cylinders. A modified arrangement allows additional space for the installation of wider rocker arm assemblies used for variable valve lift (VVL), cylinder deactivation (CDA) and other types of variable valve actuation (VVA) in these existing cylinder head designs. In the first embodiment, cam towers of conventional designs adjacent the end two cylinders are not used. At least one end support is used which may be an outboard bearing on a camshaft for each end. The wider rocker assemblies may then be installed. In an alternative embodiment, the cam towers adjacent the inner two cylinders are eliminated and a single camshaft support piece with a support bearing is installed between the inner cylinders to provide support for the camshafts. The wider rocker assemblies may then be installed on at least one of the middle cylinders. The system also includes a novel oil control valve that operates latches in switching rocker arm assemblies.
