Abstract: A fast acting valve train system for valve deactivation is provided that includes an actuator together with a switchable rocker arm. The actuator, controlled by the engine control unit and mounted to a structural housing, contains an actuator pin that retracts or extends facilitating either a deactivation or reactivation valve event. The switchable rocker arm is a two arm design that includes cam side and valve side arms that are coupled together with a locking mechanism assembly that interfaces with the actuator pin. The system is capable of fast switching times to meet the increased demands of cylinder deactivation systems.

Abstract: An apparatus includes a valve and an actuator. The valve has a portion movably disposed within a valve pocket defined by a cylinder head of an engine. The valve is configured to move relative to the cylinder head a distance between a closed position and an opened position. The portion of the valve defines a flow opening that is in fluid communication with a cylinder of an engine when the valve is in the opened position. The actuator is configured to selectively vary the distance between the closed position and the opened position.

Abstract: A method of lubricating one or more valve train (100) components includes delivering a lubricating fluid to the inner cavity (156) of a fluid collecting member (152) through a radially extending discharge portion (182) of a fluid passage (176) in a rocker arm insert. The insert fluid passage (176) is in fluid communication with a lubricating fluid source to dispense a controlled amount of lubricating fluid to one or more valve train components during operation of an engine. The radially extending discharge portion of the fluid passage in the insert may be positioned adjacent to a spherical end cap that is received in the inner cavity of the fluid collecting member.

Abstract: A valve spring device is provided with a first coil spring and a second coil spring combined in series with each other. The inside diameter (coil inside diameter) of the second coil spring is greater than the outside diameter (coil outside diameter) of the first coil spring. A part of the first coil spring including an end portion along an axis is inserted into the second coil spring, thereby forming a combined spring. The end portion of the first coil spring and an end portion of the second coil spring are connected to each other by a connecting member. The first and second coil springs are compressed along the axis as they are located in series between a cylinder head and a retainer. A shaft of a valve is passed within the coil springs.

Abstract: In a link type variable stroke engine in which a piston, a crankshaft and an eccentric shaft are linked by a linking mechanism, a counterweight part which is provided so that in a projection view on a plane orthogonal to an axis of a rotary shaft, a center of gravity of the counterweight part is located on an opposite side of the axis of the rotary shaft from an axis of the eccentric shaft rotates together with the rotary shaft. Accordingly, it is possible to effectively suppress and lessen half-order inertial exciting force occurring at the eccentric shaft.

Abstract: An internal combustion engine having cylinders capable of selectively resting during engine operation is capable of eliminating step increases in engine output when the number of operative cylinders is changed. The internal combustion engine includes a plurality of cylinders divided into two or more groups, at least some of the cylinders being restable. A throttle valve of each of the cylinders is independently operable on the basis of the group to which the cylinder belongs, and the number of resting cylinders is controlled according to the throttle grip opening. The throttle valve opening is different between the groups, except for the full opening condition and the full closure condition of the throttle valve, and an ECU is provided for opening the throttle valve of the next cylinder group before the throttle valve opening of the former cylinder group reaches the full opening condition.
