Abstract: A valve mechanism drives an exhaust valve with a valve lifter and an exhaust camshaft. Oil is supplied to a journal surface of the camshaft and a bearing supporting the camshaft journal surface through an axial oil passage formed in the camshaft. The bearing is defined by a cam cap and a bearing main body. An oil collecting recess is defined between cam cap and the bearing main body. An auxiliary delivery passage extends from the oil collecting recess to a sidewall of the bearing that is located adjacent to the valve lifter. A guide wall is formed in the sidewall to lead oil from an opening of the auxiliary delivery passage to a part of the valve lifter that generates a striking noise in the absence of buffering oil.

Abstract: A method of controlling an intake air passage of an internal combustion engine is provided. The intake air passage cyclically communicates to a combustion chamber of the internal combustion engine, thereby inducting fresh air into said combustion chamber. The cyclic communication of the intake air passage to the combustion chamber generates a pressure wave in the intake air passage. The method comprises reducing an effective length of a transmission path of the pressure wave in an upstream direction of the intake air passage as a desired air flow to the combustion chamber decreases. In accordance with the method, the effective length of the pressure wave transmission path is reduced as desired air flow decreases. With the reduced effective length, the pressure wave bounces back and forth between ends of the transmission path more often before the next cyclic communication. The more bouncing attenuates the pressure wave at the next cyclic communication. Therefore, the cylinder air charge can be stabilized when the desired air flow is decreased.

Abstract translation: 提供了一种控制内燃机的进气通道的方法。 进气通道与内燃机的燃烧室循环地连通，从而将新鲜空气引入到所述燃烧室中。 进气通道与燃烧室的循环连通在进气通道中产生压力波。 该方法包括当到达燃烧室的期望空气流量减小时，减小进气通道的上游方向上的压力波的传输路径的有效长度。 根据该方法，随着气流的减少，压力波传输路径的有效长度减小。 随着减小的有效长度，压力波在下一个循环通信之前更频繁地在传输路径的端部之间来回弹起。 在下一次循环通信时，弹跳越多，衰减压力波。 因此，当期望的空气流量减小时，气缸空气充量可以被稳定。
