Abstract: A valve drive for controlling gas exchange valves of an internal combustion engine. The valve drive has at least one valve camshaft that is supported within a cylinder head of the engine and that can be moved in rotation by a drive disk and an adjustment device, which has an adjustment motor and a gear train. The adjustment device provides for an axial movement and/or rotation of the valve camshaft relative to the drive disk in a specific manner upon actuation of the adjustment motor and by the intermediately connected gear train in order to vary in a specific manner an actuation of the gas exchange valves that occurs by cams of the valve camshaft. Also, the adjustment motor is placed predominantly or completely within a common chamber with the drive disk.

Abstract: A device for selectively changing phase relationship between first and second rotating shafts in an internal combustion engine where the first shaft is secured for rotation with a worm carrier assembly and the second shaft is secured for rotation with a worm gear includes first and second worms disposed for rotation within the worm carrier assembly and having torsional preloads with opposite hands of rotation and meshing with the worm gear. An actuator turns the first and second worms in a first direction to advance rotation of the second shaft relative to the first shaft and turns the first and second worms in a second direction to retard rotation of the second shaft relative to the first shaft.

Abstract: A method for controlling a variable valve apparatus of an internal combustion engine and a system thereof is disclosed. A method for controlling a variable valve apparatus of an internal combustion engine may include: setting a target cam phase corresponding to a current operation state of an engine received from a vehicle controller via a controller area network (CAN) bus; determining whether a deviation of the current cam phase from the target cam phase is greater than a predetermined deviation; calculating a proportion-integral-derivation (PID) sliding surface based on the target cam phase; calculating a control current for controlling a cam phase to move on the sliding surface in a case when the deviation is greater than the predetermined deviation; and operating the variable valve device so that the current cam phase can follow the target cam phase by converting the calculated control current to a driving duty ratio.

Abstract: A mechanically-actuated camshaft phaser for varying the phase of a camshaft in an internal combustion engine. The phaser comprises two colinear helical mechanisms having opposite-handed helices engaging a common nut for common rotation. One helical mechanism is operatively attached to a sprocket or pulley in time with an engine crankshaft. The other helical mechanism is operatively attached to an engine camshaft. A motive system drives the nut axially of itself along the helical mechanisms, causing a phase shift between the mechanisms and hence between the crankshaft and the camshaft. The preferred helical mechanisms are ball screws, and the preferred motive system is a worm gear driven by a worm on the shaft of an electric motor.

Abstract: A control system of an internal combustion engine is comprised of an operation angle adjustment mechanism which continuously varies an operation angle of intake valves of the engine, an air-fuel ratio detector which detects an exhaust parameter indicative of air-fuel ratio information, and a control unit which are coupled to the operation angle adjustment mechanism and the air-fuel ratio detector. The control unit feedback-controls an air-fuel ratio of the engine on the basis of the exhaust parameter and corrects the operation angle on the basis of the exhaust parameter.

Abstract: Disclosed is a variably timed rotary valve mechanism for controlling the air/fuel intake into and exhaust gases out of an internal combustion engine. There are two rotary valve shafts, one intake and one exhaust, that contain two intake and two exhaust valve ports per engine cylinder. These rotary valve shafts are driven by and synchronized with the engine crankshaft via a conventional timing belt. The timing of each of these rotary valve shafts relative to the crankshaft can be varied individually through hydraulic servomotors under control of a computerized engine management system.

Abstract: In a variable valve timing system for an internal combustion engine, a soft-landing revertive control that an electromagnetic brake is de-energized and then an angular position of a camshaft relative to a crankshaft returns to an initial position is performed by a combination of a feedback control and a feedforward control. During the revertive control, the feedback control is executed in such a manner as to temporarily halt the angular phase of the camshaft at a predetermined position, which is phase-changed by a predetermined phase angle from the initial position. After the feedback control, the operating mode is switched to a feedforward control, so as to return the angular phase of the camshaft from the predetermined position to the initial position by changing a controlled quantity or a control-signal duty cycle value for the electromagnetic brake with a predetermined time rate of change.
