    Abstract: A valve control system may include an adjustable camshaft that includes an outer shaft and an inner shaft that extends through the outer shaft. The valve control system may further include a phase shifter that comprises a first control element and a second control element that can be rotated relative to the first control element. The outer shaft and the inner shaft may each be connected with a control element. The valve control system may also include a stop coupled with the outer shaft in a torque-proof manner, as well as a counter-stop coupled with the inner shaft in a torque-proof manner. A maximal angle of rotation of the inner shaft in the outer shaft may be determined by the stop bordering on the counter-stop.”

    Abstract: The present invention provides a variable valve mechanism of an internal combustion engine, which includes a rocker arm that is driven by a cam so as to swing to drive a valve, a switching pin that is attached to the rocker arm so as to be shifted between a first position and a second position, a shift device that shifts the switching pin from the first position to the second position, and a return spring that returns the switching pin. In the variable valve mechanism, a drive state of the valve is switched by shifting the switching pin, the rocker arm is formed to have such a dimension that one end of the switching pin is exposed while projecting outward from the rocker arm, and the return spring is externally fitted to the one end of the switching pin so as to be exposed outside the rocker arm.

    Abstract: Even when a crankshaft reversely rotates, a rotation phase of a camshaft can be accurately detected. A motor shaft rotation angle, a crankshaft forward rotation angle, a crankshaft reverse rotation angle, a final crankshaft rotation angle, a sprocket rotation angle of an electric VTC where a sprocket rotates at ½ rotation speed of the crankshaft and a stator of an electric motor are integrally rotated, a motor shaft rotation angle changing amount during a control period, a sprocket rotation angle changing amount, a motor shaft rotation angle changing amount, an intake camshaft rotation angle changing amount, and a current real rotation angle of the intake camshaft are calculated sequentially, and the VTC manipulated variable is computed so that the VTC real angle follows a VTC target angle.

    Abstract: A valve train of an internal combustion engine includes at least one basic camshaft with a cam carrier provided thereupon in a rotationally fixed and axially displaceable manner. The cam carrier has at least one valve-actuating cam as well as a tubular basic element that receives the basic camshaft in at least some sections. At least one cam element of the cam carrier, in particular the valve-actuating cam, is arranged on the basic element. At least one torque-transmitting connecting element is located between the basic element and the cam element. An internal combustion engine having at least one valve train and a method for producing a valve train are also disclosed.

    Abstract: A desmodromic valve system which provides direct bidirectional displacement of a valve stem of an internal combustion engine without the aid of a rocker arm, utilizing a semirigid basket operating in conjunction with a plurality of cams for each valve. The basket is disposed about the camshaft of the engine and secured to the valve stem by an integral retainer on a bottom portion of the basket, and is constrained to motion along the valve stem axis. The basket has a pair of downwardly oriented cam followers in the upper portion thereof, spaced apart from the valve stem axis. A central cam and a parallel pair of side cams are fixedly mounted on the camshaft so as to rotate therewith, the cams substantially surrounded by the basket and cooperating therewith to provide reciprocating valve action with positive bidirectional drive. The central cam is aligned with the valve stem axis, and the side cams are spaced apart from the valve stem axis, parallel to the central cam and respectively aligned with the cam followers. During a first part of a valve cycle, the central cam pushes the valve stem down so as to positively open the associated valve, and the valve stem pulls said basket down with it via the retainer. During a second part of the valve cycle, the side cams push the basket up via their respective cam followers and thereby cause the basket to pull the valve stem so as to positively close the valve.

    Abstract translation: 一种解调型阀门系统，其利用与每个阀门的多个凸轮一起操作的半刚性篮，其提供内燃机的阀杆的直接双向位移，无需摇臂。 篮子围绕发动机的凸轮轴布置，并通过篮子底部的整体保持器固定到阀杆上，并被限制为沿着阀杆轴线运动。 篮子在其上部具有一对向下定向的凸轮从动件，与阀杆轴线间隔开。 中心凸轮和平行的一对侧凸轮固定地安装在凸轮轴上以便随其一起旋转，凸轮基本上被篮子包围并配合，以提供具有正向双向驱动的往复阀动作。 中心凸轮与阀杆轴线对准，侧凸轮与阀杆轴线间隔开，平行于中心凸轮并分别与凸轮从动件对准。 在阀循环的第一部分期间，中心凸轮向下推动阀杆，以便正确地打开相关联的阀，并且阀杆通过保持器将其向下拉。 在阀循环的第二部分期间，侧凸轮通过其相应的凸轮从动件将篮筐向上推动，从而使筐拉动阀杆，以便使阀关闭。
