Abstract: Start-up of an internal combustion engine comprises maintaining one or more engine valves in an engine cylinder in a continuously open state for more than one engine cycle during engine cranking. When it is determined that an engine parameter or transmission oil pressure has reached a predetermined value, maintenance of the one or more engine valves in the continuously open state is discontinued and fuel is subsequently provided to the engine cylinder for engine start-up. In various embodiments, the engine parameter may comprise an engine temperature parameter, an engine pressure parameter or an engine electrical parameter.

Abstract: Engine valve actuation systems and methods used to decompress an engine cylinder during engine start-up, shut-down, and for bleeder braking are disclosed. An exemplary system may include a rocker arm pivotally mounted on a rocker shaft, and a structure mounted adjacent to the rocker arm in a fixed position relative to the rocker arm. A latch piston may be slidably disposed between the rocker arm and the structure. The latch piston may be selectively extended to engage both the rocker arm and structure to limit the pivotal motion of the rocker arm and maintain the engine valves in an open condition.

Abstract: An apparatus for actuating first and second engine valves comprises a rocker arm that receives motion from primary and auxiliary valve actuation motion sources at a motion receiving end of the rocker arm. A master piston residing in a master piston bore in the rocker arm is configured to received motion from the auxiliary valve actuation motion source. A slave piston residing in a slave piston bore in the rocker arm is configured to provide auxiliary valve actuation motion to the first engine valve. A hydraulic circuit is provided in the rocker arm connecting the master piston bore and the slave piston bore, and a check valve is disposed within the rocker arm, configured to supply hydraulic fluid to the hydraulic circuit. The apparatus may be incorporated into a system comprising a rocker arm shaft and the primary and secondary valve actuation motion sources, such as an internal combustion engine.

Abstract: A system for actuating one or more engine valves comprises a lost motion assembly including locking elements to selectively lock and unlock a locking mechanism disposed within a valve train such that motions may be likewise selectively applied to, or prevented from being applied to, one or more engine valves. In an embodiment, the locking elements comprise wedges having at least one wedge inclined surface defined according to a cone frustum and configured to engage an outer recess formed in a housing, the outer recess comprising an outer recess inclined surface also defined according to the cone frustum. The device may comprise a locking mechanism disposed within a housing bore in the housing and a snubber also disposed in the housing bore. Furthermore, the outer recess may be configured to permit movement of the locking element along a longitudinal axis of the housing bore.
