Abstract: An engine is provided with a variable valve timing device which transmits a rotational force generated by a motor via a motor drive circuit to a cam shaft so as to change a rotational phase of the cam shaft relative to a crank shaft. An ECU cools a motor and a motor drive circuit when the change of the rotational phase stops during the changing of the rotational phase of the cam shaft to a target value is detected. In addition, the lock state is eliminated by driving the motor by the motor drive circuit after cooling the motor device.

Abstract: A variable valve actuating apparatus for an internal combustion engine includes an exhaust valve operating angle varying mechanism, and an exhaust valve timing varying mechanism. When the internal combustion engine is at rest, the exhaust: valve operating angle varying mechanism sets an exhaust valve operating angle relatively small, and the exhaust valve timing varying mechanism sets an exhaust valve opening timing and an exhaust valve closing timing relatively retarded. Accordingly, when the internal combustion engine is at rest, the variable valve actuating apparatus sets the exhaust valve closing timing at or close to top dead center so as to enable startup of the internal combustion engine.

Abstract: An adjusting device for the rotational position of the camshaft of a reciprocating piston engine relative to the crankshaft has a variator which is designed as a three-shaft transmission having a fixed-to-the-crankshaft input shaft, a fixed-to-the-camshaft output shaft, and an adjusting shaft. The adjusting shaft is coupled nonrotatably to the rotor of a servomotor. To limit the torsional angle between the camshaft and the crankshaft, the adjusting device has limit stops. The servomotor is connected to a control circuit which is designed for controlling the phase velocity of the torsional angle.

Abstract: A valve timing controller is driven by a motor and has a control circuit and a driving circuit. The driving circuit drives the motor according to a target rotation speed which is represented by a control signal frequency generated by the control circuit. Accordingly as the frequency becomes higher, the target rotation speed increases. When the frequency of the control signal is either lower than or equal to a first threshold frequency, or higher than or equal to a second threshold, the first threshold frequency being greater than zero and being greater than the second threshold frequency, the driving circuit stops supplying current to the motor.

Abstract: A required valve timing change rate Vreq is calculated so as to make a deviation D between a target valve timing VTtg and an actual valve timing VT small and then a required speed difference DMCRreq between a motor 26 and a camshaft 16 is calculated on a basis of the required valve timing change rate Vreq. When the deviation D is larger than a predetermined value, a required motor speed Rmreq is calculated by adding the required speed difference DMCRreq to a camshaft speed RC and a motor control value is calculated so as to control the motor speed RM to the required motor speed Rmreq. When the deviation D is not larger than the predetermined value, the camshaft speed RC is set as the required motor speed Rmreq and the motor control value is calculated so as to control the motor speed RM to the camshaft speed RC.

A fourth internally splined member can be connected to one of the other three internally splined members. A second externally splined, flexible member can be disposed with a portion thereof rotatably disposed within each of at least two of either the three or four internally splined members. Various configurations of cam members and camlobe members can be disposed as integral portions of the inner shaft and the outer shaft. The cam members can be fixed or variable, full width cam members or splittable cam members. More than one concentric camshaft can be controlled by a single dual-acting phasing mechanism. More than one dual-acting phasing mechanism can be used to control two camshafts, concentric or conventional.
