    Abstract: Objects: To provide a direct-acting type valve lifter that is simple in structure, involves a small number of components, and is capable of switching its valve lift between a high and a low lift.Means for Carrying Out the Invention: The valve lifter is mounted between a cam unit (20) and a valve stem (15). The cam unit (20) comprises a high-lift cam (22) and a low-lift cam (24) integrated to the high-lift cam. The valve lifter (30) is equipped with a side lifter (32) for slidably lifting the low-lift cams (24), a center lifter (40) for slidably lifting the high-lift cam, and hydraulic means (oil groove) (11b) for sliding the center lifter (40) so as to switch the valve lift in two levels, i.e. to switch between a high and a low lift. A cylindrical body of the valve lifter is provided on the top end thereof with a slit (33) for allowing the high-lift cam to freely rotate therein, and with sliding surfaces (32a) serving as a side lifter (32) to be in sliding contact with the low lift cam. Formed in the body of the valve lifter (lifter body) is a through-hole 34 perpendicular to the slit (33), which accommodate therein the piston type center lifter (40) such that the center lifter (40) can be slidably moved by a hydraulic pressure. When the center lifter (40) is located at a position aligned with the slit (33), the cam unit assumes a high lift mode. On the other hand, at a position well offset from the slit (33), the cam unit assumes a low lift mode. Thus, the valve lifter of the invention is composed of a small number of components, so that dimension tolerance demanded for the respective components are much relaxed, which permits easy assembly of the parts.

    Abstract translation: 对象：为了提供结构简单的直动式气门挺杆，涉及少量部件，能够在高升程和低升程之间切换其气门升程。 具体实施方式：气门挺杆安装在凸轮单元（20）和阀杆（15）之间。 凸轮单元（20）包括与高升程凸轮集成的高升程凸轮（22）和低升程凸轮（24）。 气门挺杆（30）配备有用于可滑动地提升低升程凸轮（24）的侧升降器（32），用于可滑动地提升高升程凸轮的中心升降器（40）和液压装置（油槽）（ 11b），用于滑动中心升降器（40），以便将气门升程转换成两级，即在高和低升程之间切换。 气门挺杆的圆柱体在其顶端上设置有用于允许高升程凸轮自由旋转的狭缝（33），并且用作侧升降器（32）的滑动表面（32a）处于 与低升程凸轮滑动接触。 形成在气门挺杆（升降机体）的主体中的是垂直于狭缝（33）的通孔34，其中容纳有活塞式中心升降器（40），使得中心升降器（40）能够滑动地移动 液压。 当中心升降器（40）位于与狭缝（33）对准的位置时，凸轮单元呈现高升力模式。 另一方面，在与狭缝（33）很好地偏移的位置处，凸轮单元呈现低提升模式。 因此，本发明的气门挺杆由少量的部件组成，因此要求各部件的尺寸公差宽松，这允许部件容易组装。

    Abstract: A rotational cam can be disposed on a camshaft rotationally driven by a crankshaft of an internal combustion engine. A swing cam can be swingable through the rotational cam. The swing cam has a rotational cam abutment portion which contacts the rotational cam and transmits driving force from the rotational cam to the swing cam. An abutment portion displacing mechanism can be provided for displacing the rotational cam abutment portion to change a relative distance between the rotational cam abutment portion and a center axis of the swing shaft. Changing the relative distance allows changing a lift and the like of a valve.

    Abstract: A variable valve operating device is provided that can swiftly adjust a valve timing of an engine and is for adjusting a valve lift and the valve timing of the engine. The variable valve operating device includes a rocking cam, a rocking cam support member, a valve, a rocking position changing unit, and a lock unit that can fix the rocking cam support member so as not to move during a valve-opening period of the valve. The lock unit includes a support base that movably supports the rocking cam support member, and a push-link which is rocked by an actuator. When a tip end of the push-link abuts against the rocking cam support member, the push-link pushes the rocking cam support member toward the support base.

    Abstract: An electromechanical VVA system for controlling the poppet valves in the cylinder head of an internal combustion engine. The system varies valve lift, duration, and phasing in a dependent manner for one or more banks of engine valves. A rocker subassembly for each valve is pivotably disposed in roller bearings on a rocker pivot shaft between the camshaft and a roller follower. A control shaft supports the rocker pivot shaft for controlling a plurality of rocker subassemblies mounted in roller bearings for a plurality of engine cylinders. The control shaft rotates about its axis to displace the rocker pivot shaft and change the angular relationship of the rocker subassembly to the camshaft, thus changing the valve opening, closing, lift and duration. An actuator attached to the control shaft includes a worm gear drive for positively rotating the control shaft.

    Abstract: An engine that includes two intake and two exhaust valves for each cylinder is equipped for single valve constant lift engine braking. The exhaust valves may be actuated in a conventional manner via a rotating cam and a rocker arm coupled to a bridge that spans between the pair of exhaust valves. Engine braking is accomplished by actuating a brake actuator to hold one of the exhaust valves partially open, while the other of the two exhaust valves is allowed to close. Seating velocity of the non-braking valve is limited by including a second actuator button, namely a valve seating actuator, on the rocker arm that engages the valve bridge above the non-braking valve as it moves toward its closed position when the brake actuator is actuated.

    Abstract: A valvetrain system mechanization for an internal combustion engine using compression ignition, including homogeneous charge compression ignition, having two intake and one or more exhaust valves per cylinder. The valves are operated by dual overhead camshafts having two-step cams. The intake and exhaust camshafts are provided with phasers for varying the opening and closing of the intake and exhaust valves. A two-step roller finger follower is disposed for each valve between the cam lobes and the valve stem. The two sets of intake and exhaust valves are controlled by separate oil control valves. Swirl of gases may be introduced by mismatching the lifts of the valves. The valve opening times, closing times, lifts, fuel injection, compression ratio, and exhaust gas recirculation may be varied to optimize combustion conditions for a range of engine operating modes.
