Abstract: A control apparatus includes a driving device that is capable of operating regardless whether the engine is running or not. A variable valve actuation mechanism is driven by the driving device. During an idling operation of the engine, a control section controls the driving device such that the variable valve actuation mechanism maintains the valve timing at a valve timing advanced relative to a most retarded valve timing. The control section controls the driving device such that the variable valve actuation mechanism changes the valve timing to the most retarded valve timing after a stopping operation of an autonomous operation of the engine is initiated. Therefore, shock due to the initiation of the engine starting operation is reduced without decreasing fuel economy.

Abstract: In a valve timing adjusting apparatus, an, outer peripheral surface of each projection of an internal gear, which is received in a corresponding engaging hole of a guide rotator, may have reduced surface sections, which are radially inwardly reduced toward a radial center of the projection along a radial line of the internal gear that passes through the radial center of the projection to have a reduced radial size in comparison to a radial size of the rest of the outer peripheral surface of the projection. Alternatively, an inner peripheral surface of each engaging hole may have recessed surface sections, which are radially recessed from the rest of the inner peripheral surface of the engaging hole along a radial line of the guide rotator that passes through a center of the inner peripheral surface of the engaging hole.

Abstract: In a variable valve timing apparatus in which a phase of an intake valve is changed at an amount of change according to a rotational speed of relative rotation between an electric motor as an actuator and a camshaft, the set upper limit value of the rotational speed of relative rotation and a coefficient Nθ of conversion from a required phase-change amount to the rotational speed of relative rotation ΔNm in each control period are set at smaller values at the time of engine stop than at the time of engine operation. As a result, the rotational speed of the electric motor in the VVT operation at the time of engine stop is reduced thereby reducing the operation sound of the variable valve timing apparatus.

Abstract: In the case where an intake valve has its phase in a first region between a most retarded angle and CA(1), the rotational speed of relative rotation between an output shaft of an electric motor and a sprocket is reduced at a reduction gear ratio R(1) to change the phase of the intake valve. In the case where the intake valve has its phase in a second region between CA(2) and a most advanced angle, the rotational speed of relative rotation is reduced at a reduction gear ratio R(2) to change the phase of the intake valve. As long as the rotational direction of relative rotation is the same, the phase of the intake valve is changed in the same direction for both of the first region between the most retarded angle and CA(1) and the second region between CA(2) and the most advanced angle.
