摘要： In a valve timing control device, when a camshaft is retained relative to a timing pulley, a hydraulic piston is applied with a force which moves it in a direction toward an advancing-side hydraulic chamber (i.e., in the direction to vary a valve timing to a delaying side) owing to reaction of the driving torque of the camshaft. This force causes fluid to leak out of the advancing-side hydraulic chamber, and the hydraulic piston is liable to move toward this hydraulic chamber. However, fluid of an amount corresponding to an amount of this leakage is supplied to the advancing-side hydraulic chamber by way of a control valve. Also, discharge of fluid from a delaying-side hydraulic chamber via the control valve is stopped. Thus, the movement of the hydraulic piston toward the advancing-side hydraulic chamber when the hydraulic piston is retained at a desired position is prevented. Therefore, the hydraulic piston can be stably retained at the desired position, and a desired valve timing can be maintained.

摘要： 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.

摘要： A control apparatus for an internal combustion engine is employed for a multi-cylinder internal combustion engine. The control apparatus includes a variable valve operating mechanism which changes a valve characteristic of an engine valve; a valve stop mechanism which stops opening/closing of the engine valve in at least one cylinder; and a controller which executes a variable valve control that makes an actual value of the valve characteristic match a target value by executing a hydraulic pressure control for the variable valve operating mechanism, and which operates the valve stop mechanism so that a reduced-cylinder operation is performed when an engine operating state is in a preset reduced-cylinder operation region. If it is determined that a pressure of hydraulic fluid supplied to the variable valve operating mechanism satisfies a preset condition when the engine operating state is in the reduced-cylinder operation region, the controller prohibits the variable valve control.
