    Abstract: An engine camshaft drive includes timing belt pulleys which are angularly adjustable on their respective camshafts to provide manual adjustment of the engine valve timing. The arrangement features combination securing and adjusting means in the form of a threaded stud having an eccentric body portion intermediate its ends that coacts with a radially elongated opening in its associated drive sprocket to provide angular adjustment of the sprocket on the camshaft, while the stud also provides means for securing the drive sprocket to the camshaft when the adjustment has been completed.

    Abstract: A timing sprocket for a camshaft is provided with a number of positioning holes equally spaced in a circle about its axis of rotation. A vernier plate connected to the camshaft is provided with alignment holes equally spaced in a corresponding circle as the circle of positioning holes but at a slightly greater or lesser angle. Alignment of a positioning hole and an alignment hole using a positioning pin permits incremental rotational adjustment of the sprocket wheel relative to the camshaft for angular increments equal to the difference between the angles of the positioning holes and the angles of the alignment holes.

    Abstract: An engine assembly includes an engine structure, a camshaft supported on the engine structure, a first cam phaser coupled to a first axial end of the camshaft, and a locating pin. The camshaft includes a first shaft, a second shaft, a first cam lobe and a second cam lobe. The first shaft defines a first opening. The second shaft is supported within the first shaft and defines a second opening. The first cam lobe is located on and fixed for rotation with the first shaft. The second cam lobe may be located on the first shaft and fixed for rotation with the second shaft. During assembly, the first cam phaser is located on the camshaft and the locating pin may be inserted through the first and second openings to rotationally fix the first and second shafts. The first cam phaser is then secured to the camshaft.

    Abstract: In valve timing control after issuance of an engine stop instruction with a prescribed value set as a target phase, an ECU delays permission of an engine stop process within a prescribed time period while an intake valve phase has not yet reached the target value, so that a valve timing control operation is continued while the engine operation is continued in an idle state. After the lapse of a prescribed time period from the issuance of the engine stop instruction, however, the ECU permits the engine stop process no matter whether the intake valve phase has reached the target value or not. As a result, the amount of valve timing that can be changed by the valve timing control in the engine stop operation can be increased, without causing any uncomfortable feeling of the driver.

    Abstract: In a method for setting the rotary angle position of the camshaft of a reciprocating piston internal combustion engine relative to the crankshaft, the crankshaft is connected to the camshaft by means of a triple-shaft gear mechanism. This triple-shaft gear mechanism has a drive shaft which is fixed to the crankshaft, an output shaft which is fixed to the camshaft, and an adjusting shaft which is driven by an electric motor. A crankshaft sensor signal is detected which changes its state when the rotary angle of the crankshaft changes. Furthermore, an adjusting shaft sensor signal is detected which changes its state when the rotary position of the adjusting shaft changes. A phase angle signal is updated, starting from a reference rotary angle value, when the state of the crankshaft sensor signal and/or of the adjusting shaft sensor signal changes, and is adjusted to a provided setpoint phase angle signal. The ignition of the internal combustion engine is then switched off and/or the rotational speed of the crankshaft is lowered to below a prespecified minimum rotational speed value. While the crankshaft and/or the camshaft are/is still rotating, the electric motor is supplied with power in such a way that the camshaft rotates in the direction of a prespecified reference position relative to the crankshaft. When the internal combustion engine is next started, the camshaft and crankshaft are positioned in accordance with the reference position and this is detected with the aid of a sensor. The phase angle signal is set to a reference value and then adjusted to the setpoint phase angle signal.

    Abstract: A system for the rotation of a camshaft relative to a crankshaft of an internal combustion engine, which includes a drive pulley connected to the crankshaft of the engine through a chain, belt, or sprocket drive, and includes an electric motor that transfers torque to the camshaft of the engine. The electric motor is flanged directly to one end of the and is a primary drive unit of the camshaft as well as a servomechanism to adjust and maintain a controlled camshaft angular shift, whereas the drive pulley is fastened to and moves about the other end of the camshaft within a defined range of rotation and is provided as a forced synchronization instrument for the electric motor within the range of rotation, as well as being a secondary drive unit of the camshaft. Further, the electric motor (7) is connected to an RPM controller (10) that synchronizes and modifies the RPM of the electric motor (7) relative to the RPM of the drive pulley (4).
