摘要： A control device for an internal combustion engine includes a controller. The controller controls the relative rotation phase of the exhaust camshaft in accordance with the relative rotation phase of the intake camshaft. When a request for locking the relative rotation phase of the intake camshaft at an intermediate phase is generated, the controller controls the relative rotation phase of the exhaust camshaft such that the relative rotation phase of the exhaust camshaft is changed to a phase corresponding to the intermediate phase independently from the relative rotation phase of the intake camshaft.

摘要： A control device for an engine includes a variable valve timing mechanism. The control device performs learning a holding control amount of a hydraulic valve when actual valve timing is held at a fixed timing in each of spring and non-spring regions, and an updating. The updating includes updating the control amount for the non-spring region whenever the control amount for the spring region learned drops below the control amount for the non-spring region to satisfy a relationship with the control amount for the non-spring region being less than or equal to the control amount for the spring region, and/or updating the control amount for the spring region whenever the control amount for the non-spring region learned exceeds the control amount for the spring region to satisfy a relationship with the control amount for the spring region being greater than or equal to the control amount for the non-spring region.

摘要： A controller for a variable valve device of an internal combustion engine includes a hydraulic valve timing changing mechanism that changes the valve timing VT of an intake valve, a valve timing locking mechanism that locks the valve timing VT to an intermediate phase, and an electronic controller that controls the operation of the valve timing changing mechanism. The electronic controller limits the variable range of the valve timing VT in accordance with the composition of hydraulic oil, when the operational state of the valve timing changing mechanism is a phase-unlocked state in which the valve timing VT can be changed.

摘要： A drive circuit (203) of an actuator (2) calculates an actual working angle from an actual operation quantity with reference to a reference table used to calculate a target operation quantity, and transmits the actual working angle and the actual operation quantity to a command unit (4). The command unit (4) determines whether or not the received values of the actual working angle and the operation quantity correspond to the valve working angle and the operation quantity of the reference table stored in the command unit (4), to detect a discrepancy between the operation modes of the actuator (2) and the command unit (4).

摘要： A controller for a variable valve actuation device is provided. The controller prevents the startability of an internal combustion engine from being degraded. An electronic controller (91) performs a phase advancing control at engine starting to advance valve timing (VT) by oil pressure of an phase advancing chamber (37) and oil pressure of a phase retarding chamber (38) provided in a phase changing mechanism (30) if a residual oil amount (Q) is greater than or equal to a reference oil amount (QA) at engine starting. In addition, when the valve timing (VT) reaches an intermediate angular phase (VTmdl), the valve timing (VT) is held in the intermediate angular phase (VTmdl) by oil pressure of the phase changing mechanism (30).
