摘要： A brushless motor of a variable valve mechanism varies a actuation parameter of an intake valve of an engine. A position sensor outputs a pulse signal when the brushless motor rotates. A position counter calculates a counter value by counting edges of the pulse signal. A motor control device obtains a detection value of a motor rotational angle based on the counter value when the motor control device is in a powered state. An engine control device determines that the detection value of the motor rotational angle is displaced from the actual value when the engine control device detects that the engine is operating and the motor control device portion is in a non-powered state.

摘要： A control apparatus calculates a exhaust gas air-fuel ratio of a plurality of cylinders, in which the operation angle of an intake valve is set to a predetermined operation angle, e.g., a maximum operation angle, based on a value output from an air-fuel ratio sensor so as to minimize a variation in an fuel injection quantity between the plurality of cylinders by that exhaust gas air-fuel ratio. That is, the exhaust gas air-fuel ratio of the plurality of cylinders, in which the valve opening characteristics of the intake valve and an exhaust valve are set such that the intake air amount to be introduced into the plurality of cylinders is limited by the opening amount of a throttle valve, for example, and not limited by the valve opening characteristics of the intake valve or the exhaust valve is calculated, and the variation in the fuel injection quantity among the plurality of cylinders is then reduced by that exhaust gas air-fuel ratio. Then, the variation in valve opening characteristics among the cylinders is reduced.

摘要： An electronic control unit sets a target valve actuation parameter in accordance with an operating state of an internal combustion engine, and controls a variable valve actuation mechanism such that an actual valve actuation parameter of an intake valve becomes equal to the target valve actuation parameter. The variable valve actuation mechanism changes a valve actuation parameter of the intake valve. From before an initial fuel injection is performed to when a starting process of the engine is completed, the electronic control unit sets the target valve actuation parameter to an engine starting valve actuation parameter at which the valve closing timing of the intake valve coincides with or is close to a bottom dead center of the intake valve.

摘要： A device for controlling an internal combustion engine, comprising a variable valve mechanism for varying opening areas (valve lift) or the working angles (valve-opening periods) of at least either the intake valves or the exhaust valves, wherein a pressure in the cylinder is calculated based on the opening area or the working angle of at least either the intake valve or the exhaust valve varied by the variable valve mechanism, and the internal combustion engine is controlled based on the pressure in the cylinder. Upon calculating the pressure in the cylinder based on the opening areas or the working angles of the intake and exhaust valves, it is possible to more suitably control the internal combustion engine based not only upon the peak combustion pressure in the cylinder like when a combustion pressure sensor is used but also upon a pressure in the cylinder at a moment other than the peak combustion pressure.
