  • Linkage between an auxiliary motion source and a main motion load path in an internal combustion engine
    Patent number: 11313259
    Abstract: In an internal combustion engine, a linkage is provided between an auxiliary motion source and a main motion load path, such that motions received by the linkage from the auxiliary motion source result in provision of a first force to at least one engine valve and a second force to the main motion load path in a direction toward a main motion source. Where an automatic lash adjuster is associated with the main motion load path, the second force may be selected to aid in the control of lash adjustments made by the automatic lash adjuster. In various embodiments, the linkage may be embodied in an mechanical linkage, whereas in other embodiments, an hydraulic linkage may be employed. The linkage may be incorporated into, or otherwise cooperate, a valve bridge or a rocker arm.

  • System for engine valve actuation comprising lash-prevention valve actuation motion
    Patent number: 10526936
    Abstract: A system for actuating engine valve comprises a main valve actuation motion source configured to supply main valve actuation motions to the at least one engine valve via a main motion load path, and an auxiliary valve actuation motion source separate from the main valve actuation motion source and configured to supply complementary auxiliary valve actuation motions to the at least one engine valve via an auxiliary motion load path. A lost motion component is configured, in one state, to maintain lash between the auxiliary valve actuation motion source and the auxiliary motion load path or within the auxiliary motion load path and, in another state, to take up this lash. The auxiliary valve actuation motion source is further configured to supply at least one lash-prevention valve actuation motion that substantially matches at least one of the main valve actuation motions.
