Abstract: A motor drive device for valve timing control of an internal combustion engine includes: a motor drive unit that controls a phase of a camshaft to drive a motor for controlling opening and closing operation of a valve; and a determination unit that determines whether a timing is to start up the motor or to normally drive the motor. The motor drive unit drives the motor with an advance angle when it is determined that the timing is to normally drive the motor by the determination unit, and the motor drive unit normally drives the motor without the advance angle when it is determined that the timing is to start up the motor.

Abstract: A valve timing control device includes a lock mechanism having a hole portion formed in one of the driving-side/driven-side rotational members, a sleeve in the hole portion, a lock member in the sleeve and capable of projecting and retracting with respect to the other of the driving-side/driven-side members, and a lock hole formed in the other of the driving-side/driven-side members such that the lock member can be fitted to the lock hole when the lock member projects. The lock mechanism constrains a relative rotational phase of the driven-side rotational member with respect to the driving-side rotational member at a predetermined phase when the lock member is fitted to the lock hole. A first chamfered surface is formed in the circumferential direction at an inner-circumferential corner of an end of the sleeve on the side opposite to the side facing the lock hole.

Abstract: According to a control strategy, a cylinder valve control device is monitored and operation of the engine is modified. The cylinder valve control device includes a driving shaft driven by the engine to drive an intermediate member which in turn drives a cam arranged to open an engine intake valve, and a driver which is operative in response to a command to vary an amount of eccentricity of the intermediate member with respect to a shaft axis of the driving shaft. During one mode of engine operation, the intermediate member is supported in a support for rotation about an axis in eccentric condition with respect to the shaft axis to accelerate and decelerate the cam with respect to rotation of the driving shaft. During another mode of engine operation, the intermediate member is in concentric condition with respect to the shaft axis to provide a synchronous motion of the cam with rotation of the driving shaft. In response to the eccentricity of the intermediate member, the engine operation is modified.

Abstract: A cam shaft assembly comprises a first coupling between a drive collar rotatable with a driving shaft and an annular disc at a first position spaced from the shaft axis, and a second coupling between the disc and said hollow cam at a second position angularly spaced from said first position with respect to the shaft axis. The first and second couplings are so spaced from the shaft axis that they are at varying distances from the axis of the disc during operation. Each of the first and second couplings has a movable connection with the disc to permit the variation in its distance from the axis of the disc. The disc is rotatably supported in a disc housing. A control rod is mounted for rotation and has an eccentric control cam which controls movement of the disc housing. A pivot shaft extends through the disc housing for allowing movement of the disc housing following the eccentric control cam in which said plurality of hollow cams are disposed.

Abstract: A cam is capable of angular movement on a cam shaft. A disc eccentrically mounted on the shaft is driven from the shaft via a pin connection and drives the cam by a similar connection. The degree of eccentricity of the disc, which is adjustable, determines the acceleration and deceleration given to the cam as it rotates. There is disclosed an electro-mechanical servo system, responsive to the speed of an engine incorporating the cam and cam shaft, for controlling the eccentricity of the disc in dependence on the speed. Also disclosed is an electronic servo system for the same purpose.
