摘要： The present invention provides a variable valve mechanism control device that is capable of reducing the power consumption and rating of an electric motor by allowing camshaft rotary inertia torque to reduce spring reaction force during a valve lift. Camshaft rotary inertia force is increased to a value not smaller than a predetermined value before the start of a valve lift. During the time interval between the instant at which the valve lift starts and the instant at which the maximum lift is provided, the spring reaction force of a valve spring is used as deceleration torque for the camshaft rotary inertia force. During the time interval between the instant at which the maximum lift is provided and the instant at which the valve lift terminates, the spring reaction force is used as acceleration torque for the camshaft rotary inertia force. The camshaft rotary inertia force cancels the spring reaction force so that motor torque generated during a valve lift is composed of counter-friction torque only.

摘要翻译： 本发明提供一种可变阀机构控制装置，其能够通过允许凸轮轴旋转惯性转矩降低气门升程期间的弹簧反作用力而能够降低电动机的功率消耗和额定值。 在阀提升开始之前，凸轮轴旋转惯性力增加到不小于预定值的值。 在阀提升开始的瞬间与提供最大升程的时刻之间的时间间隔期间，使用阀弹簧的弹簧反作用力作为凸轮轴旋转惯性力的减速扭矩。 在提供最大升程的瞬间与气门升程终止时刻之间的时间间隔期间，弹簧反作用力用作凸轮轴转动惯性力的加速转矩。 凸轮轴旋转惯性力抵消弹簧反作用力，使得在气门升程期间产生的电机扭矩仅由反摩擦力矩组成。

摘要： During a fuel cut, a recommended reactivated cylinder and a reactivatable cylinder are determined based on the stopped positions of an intake valve and an exhaust valve (step 104). A fastest reactivatable cylinder is then determined based on the crank angle, from among the recommended reactivated cylinder and the reactivatable cylinder (step 108). Also, the rotating direction of a motor when a variable valve drive apparatus starts to be driven again when the fastest reactivatable cylinder is made the reactivated cylinder is also determined. When a reactivation command is output, operation resumes from the fastest reactivatable cylinder when the situation calls for rapid reactivation (step 124). When the situation does not call for rapid reactivation, operation resumes from the recommended reactivated cylinder (step 118).

摘要： The present invention makes it possible to favorably change valve-opening characteristics of a valve using a simplified configuration without leading to an increase in the number of components and also without causing an increase of friction due to sliding, in a valve operating apparatus for an internal combustion engine in which the valve-opening characteristics of the valve are variable. A changeover mechanism for switching the connection/disconnection of rocker arms disposed between cams and a valve is provided. When a slide pin reaches a displacement end in the retreating direction of changeover pin, the biasing force of a return spring acting on changeover pins is received by an engaging part between a notch part provided in the slide pin and a lock pin in a state separated from a camshaft.

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： Disclosed is a variable valve mechanism for an internal combustion engine. The variable valve mechanism accurately adjusts the valve operating angle although its structure is simple. The variable valve mechanism includes a control pin 48, which is inserted into a pin insertion hole 38 in a control shaft 16; a bearing hole 44, which is formed in a control member 26; and an adjustment pin 50, which is rotatably supported by the bearing hole 44. The adjustment pin 50 comes into surface contact with the control pin 48 to inhibit the control member 26 from rotating relative to the control shaft 16. The valve operating angle is adjusted by replacing the adjustment pin 50 with another having a different dimension B. Such adjustment pin replacement changes the distance A between the center line of the bearing hole 44 and the center line of the control pin 48, thereby changing the relative angle θ between the control shaft 16 and control member 26. When the adjustment pin 50 rotates within the bearing hole 44, the surface contact between the adjustment pin 50 and control pin 48 is maintained irrespective of the magnitude of the relative angle θ.

摘要： A valve drive system comprises a power transmitting mechanism (13) that converts rotary motion of an electric motor (12) into opening and closing motion of an intake valve (3) provided in a cylinder (2) of an internal combustion engine (1) to transmit power from the electric motor (12) to the valve (3) via a cam (152); and a rotational angle restricting mechanism (16) that is provided in a motion transmission path that extends from the electric motor (12) to the cam (152) and restricts rotation of the cam (152) within a predetermined angular range that is set so that a piston (5) of the engine (1) and the intake valve (3) do not interfere with each other. The rotational angle restricting mechanism (16) comprises a flange (161) that rotates as a unit with a camshaft (151) and forms a slotted groove hole (161a) thereon; and a stopper pin (162) that is inserted into and retracted from the groove hole (161a).
