LINKAGE BETWEEN AN AUXILIARY MOTION SOURCE AND A MAIN MOTION LOAD PATH IN AN INTERNAL COMBUSTION ENGINE

摘要

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.

主权项

1. A system for use in an internal combustion engine having at least one engine valve associated with a cylinder, the system comprising:
a main motion source configured to supply motions to the at least one engine valve along a main motion load path; an auxiliary motion source configured to supply motions to the at least one engine valve; and a linkage configured to receive the motions from the auxiliary motion source and provide a first force to the at least one engine valve and a second force to the main motion load path in a direction toward the main motion source.
