摘要： At the time of reference position learning, an operation amount of an actuator is set such that intake valve phase changes to a position of most retarded angle in a region where the amount of change in intake valve phase relative to the actuator operation amount is small (S110). When the intake valve phase reaches the position of most retarded angle and the change in the intake valve phase stops (YES at S140), it is determined that the intake valve phase has reached the position of most retarded angle as the reference phase, and learning is completed. Further, in response to completion of learning, power supply to the electric motor as the actuator is stopped. Consequently, it becomes possible to reduce power consumption and to protect the apparatus at the reference position learning for ensuring accuracy in detecting valve opening/closing timing.

摘要： At the time of reference position learning for ensuring accuracy in detecting a valve timing, an operation amount of an actuator is set such that intake valve phase changes to a position of most retarded angle as a reference phase. When the intake valve phase reaches the most retarded angle and the change in the intake valve phase stops (YES at S150), it is determined that the intake valve phase has reached the reference phase and the learning is terminated normally. If the learning operation does not end normally even after the time lapse from the start of learning exceeds a limit time Tlmt, the reference position learning is terminated forcibly (YES at S170), and power supply to the actuator is stopped. Thus, power consumption can be reduced and the apparatus can be protected at the time of reference position learning.

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 high-pressure fuel supply system is suitable for an internal combustion engine having an in-cylinder injector (110) for injecting a fuel into a cylinder. The high-pressure fuel supply system includes a high-pressure fuel pump (200, 300) driven by an engine, a high-pressure delivery pipe (112) supplying the fuel from the high-pressure fuel pump (200, 300) to the in-cylinder injector (110), and an actuation valve provided with a leakage function provided between the high-pressure fuel pump (200, 300) and the high-pressure delivery pipe (112). An amount of leakage in the actuation valve provided with the leakage function is set to an amount not smaller than a discharge amount of the high-pressure fuel pump (200, 300).

摘要： An ECU executes a program including the steps of: controlling, when the phase of an intake valve is a phase advanced relative to a threshold value CA (FF) (NO in S106), an electric motor operating an intake VVT mechanism by feedback control (S202); and controlling, when the phase of the intake valve is a phase retarded relative to the threshold value CA (FF) (YES in S106), the electric motor by feed-forward control (S200). Under the feed-forward control, a duty command value is output that is smaller than an upper limit of a duty command value under the feedback control.

摘要： In a variable valve timing apparatus having a VVT mechanism in each of a plurality of banks, start of a valve timing control is not permitted (S190) until reference position learning of valve timing is completed (S170, S180) in the corresponding bank and in other banks. Accordingly, the plurality of banks come to have matching valve timing setting at the time of valve timing control, whereby variation in the amount of air introduced to cylinders can be suppressed, and satisfactory combustion characteristics can be maintained.

摘要： An object of the present invention is to enhance precision of air-fuel ratio control after return from fuel cut in a control device for an internal combustion engine that has a plurality of fuel injection modes, and performs calculation of a fuel injection amount by a method corresponding to an injection mode in use. For this object, the control device for an internal combustion engine the present invention provides normally determines the injection mode in response to an operation state, but designates a specific injection mode with a higher priority than the injection mode determined in response to the operation state at a time of return from fuel cut. For a predetermined time period after the return from fuel cut, the control device prohibits the injection mode from being changed in response to the operation state, and keeps fuel injection according to the designated specific injection mode.
