摘要： The rotary motion of a camshaft is transmitted from a first drive cam to a slide surface of a swing cam arm via intermediate members so that the swing cam arm lifts a valve. In this instance, the operating characteristic of the valve changes when the rotation position of a control shaft changes to change the positions of the intermediate members on the slide surface. When the operating characteristic control mode for the valve is to be changed from variable control to fixed control, coupling means couples the swing cam arm and input arm, thereby causing a second drive cam to swing the swing cam arm. The setting for the lift amount of the valve that is obtained when the second drive cam swings the swing cam arm is not smaller than a maximum lift amount setting for a situation where the first drive cam swings the swing cam arm.

摘要： A variable valve operating device is provided that allows an ideal valve timing-lift characteristic to be realized by associating a change in a valve timing with a change in a valve lift amount. A rotation motion of a drive cam is transmitted to a slide surface of a swing member via an intermediate member. Positions of the intermediate member on the slide surface are varied in association with the rotation of a control shaft by an interlock mechanism. The slide surface is formed to be curved toward the drive cam so that the distance from the center of a camshaft increases toward the farthest point from the swing center of the swing member within the area which the intermediate member contacts from the nearest point from the swing center of the swing member within the area which the intermediate member contacts.

摘要： An internal combustion engine valve mechanism including a rocker arm, which includes a bearing section and a rocker roller, and an HLA. The HLA has a pivot, which is to be inserted into the bearing section, and supports one end of the rocker arm. The pivot has a spherically curved surface, whereas the bearing section has a shell-shaped dent. A swing arm rotates in synchronism with camshaft rotation and gives roller pressure force to the rocker roller. The direction in which the swing arm presses the rocker roller shifts toward the HLA when the lift of a valve disc increases. An osculating circle is inclined by inclining the axis of the bearing section at an angle of α° relative to the axis of the HLA.

摘要： The present invention relates to a variable valve operating device and a valve opening amount adjustment method, and can accurately control the amount of in-cylinder air and the strength of a swirl flow. The variable valve operating device according to the present invention includes a valve mechanism that can select a dual valve variable control mode in which the valve opening amounts of a first valve and a second valve, which are of the same type and provided for the same cylinder, can be varied continuously or in multiple steps. A valve opening amount difference is provided when the valve opening amounts are minimized in the dual valve variable control mode so that the valve opening amount of the first valve is larger than that of the second valve. In addition, adjustments are made so that the minimum valve opening amount of the first valve does not vary from one cylinder to another.
