    摘要: A cylinder head includes a cylinder head body provided with intake and exhaust ports opened toward a combustion chamber and capable of being closed by valves, the intake and exhaust ports being separated from each other in a circumferential direction around a cylinder central axis. An opening section of at least one of the intake or exhaust ports facing the combustion chamber is provided with a seat surface centered on a valve axis and a tapered surface is disposed closer to the combustion chamber than the seat surface, the tapered surface gradually increasing in diameter closer to the combustion chamber. A central axis of the tapered surface is disposed eccentrically from the valve axis toward the cylinder central axis.

    摘要: A method of lubricating one or more valve train (100) components includes delivering a lubricating fluid to the inner cavity (156) of a fluid collecting member (152) through a radially extending discharge portion (182) of a fluid passage (176) in a rocker arm insert. The insert fluid passage (176) is in fluid communication with a lubricating fluid source to dispense a controlled amount of lubricating fluid to one or more valve train components during operation of an engine. The radially extending discharge portion of the fluid passage in the insert may be positioned adjacent to a spherical end cap that is received in the inner cavity of the fluid collecting member.

    摘要: A multi-mode valve control mechanism for an engine includes a primary cam follower rotatably mounted within a mount and having one end engaging a camshaft. One or more secondary cam followers are rotatably mounted within the mount and having one end engaging the camshaft. Each secondary cam follower is operatively coupled to a shaft. A follower is dedicated to each cam lobe. A frequency and a duration at which valves in a valve train are actuated is changed by activating only the primary cam follower in a first mode of operation, or activating both the primary cam follower and the one more than one secondary cam followers in a second mode of operation, depending on whether the control mechanism has been activated or not. In either mode of operation, the entire valve train assembly is actuated.
