摘要： A lubricating system for a valve operating system includes a valve operating system configured to reciprocate a valve for substantially opening and closing a port connected to a combustion chamber of an engine, and an ejecting device provided with an outlet from which a lubricating liquid is ejected. The valve operating system includes a drive cam, a driven member configured to contact the drive cam, a pivot member which is attached to the driven member and is configured to transmit movement of the driven member to the valve, and a relative position changing device configured to change relative positions of the driven member and the pivot member. The outlet of the ejecting device is oriented to face sliding surfaces of the driven member and the drive cam at least in a period which is a part of one rotation of the drive cam.

摘要： A pivot cam mechanism included in a valve operating system is configured such that a coupling pin is supported at a pivot member in a position closer to a camshaft than a control shaft, and the pivot member and the driven member are integrally pivotable according to the rotation of the drive cam while changing relative attitudes of the driven member and the pivot member. Positions and shapes of the drive cam, the driven member, and the pivot member are designed so that a valve maximum acceleration point at which an acceleration of a valve body is at a maximum is located in a front part of a valve acceleration period in which the acceleration of the valve body has a positive value while the drive cam is rotating once.
