Abstract: The rocker arm assembly has an anti-inversion part that prevents a support pin from inverting, ensuring proper orientation of the support pin, on which a rocker arm is rotatably mounted, is maintained. The anti-inversion part can be a washer, a plate, a plug, or a sleeve. The washer, which has a flat face and a curved face, is intended for use with a cylindrical support pin which matches the curved face of the washer. The plate can include various combinations of tabs, flanges, and/or protrusions that extend in different directions. The plug can resemble any desirable shape, and is removed prior to final assembly. The sleeve can be hollow and is removable.

Abstract: One possible embodiment of the invention is essentially an apparatus and methodology for mounting a rocker arm assembly to a cylinder head of an internal combustion engine comprising of at least a unitary stanchion to which multiple rocker arms may be moveably connected. In least one embodiment, the unitary stanchion may comprise a base from which project multiple rows of pedestals. Two of more of these rows may be set in essentially parallel orientation, which further defines a primary space in which a portion of the rocker arm is located. The unitary stanchion may be secured to the cylinder head thorough multiple rows of fasteners. The footprint of the base of unitary stanchion could allow the unitary stanchion to possibly act as generally efficient external buttress for generally providing greater support across the top of the cylinder head.

Abstract: An internal combustion engine which includes a valve deactivation mechanism for reducing an output power shock upon changing of the cylinder number. In an internal combustion engine which includes a valve deactivation mechanism driven by a slide pin which is driven by hydraulic pressure, response delay time after a signal is sent to oil control valves until an intake valve and an exhaust valve are activated or deactivated is used to form a control map in response to control parameters, and the valve deactivation mechanism is controlled based on the control map.

Abstract: A control system for an engine having a first cylinder and a second cylinder is disclosed having a first engine valve movable to regulate a fluid flow of the first cylinder and a first actuator associated with the first engine valve. The control system also has a second engine valve movable to regulate a fluid flow of the second cylinder and a sensor configured to generate a signal indicative of a pressure within the first cylinder. The control system also has a controller that is in communication with the first actuator and the sensor. The controller is configured to compare the pressure within the first cylinder with a desired pressure and selectively regulate the first actuator to adjust a timing of the first engine valve independently of the timing of the second engine valve based on the comparison.
