    • A method for controlling variable feedback gain energization of an electromagnetic−driven intake/exhaust valve of an internal combustion engine in which the opening/closing speed of the intake/exhaust valve driven by an electric magnet of small capacity is increased, and the performance of controlling the terminating speed in the opening/closing operation is brought close to 0. According to the method for controlling the variable feedback gain energization, the target moving speed of an armature with respect to the electric magnet is determined corresponding to the distance between the armature and the electric magnet, the energization of the electromagnetic−driven valve is subjected, at least in a part thereof, to feed−forward control so that the actual moving speed of the armature to the electric magnet is matched with the target moving speed, and further subjected, at least in other parts, to feedback control according to the deviation of the actual moving speed from the target moving speed thereof. Here, the gain of the feedback control is modified according to the relationship between the actual moving speed and the target moving speed. In addition, the energization control is learned and corrected according to the deviation between the actual moving speed and the target moving speed, and the measured value of the terminating speed of the opening/closing operation.

    • The cam surface of an inlet cam has a main lift portion for causing an intake valve to perform a basic lifting action, and a sublift portion assisting the function of the main lift portion. The main lift portion and the sublift portion continuously change axially of the inlet cam. An axial travel actuator moves the inlet cam to adjust the axial position of the cam surface which drives the intake valve. The inlet cam being axially moved results in the valve being given a variety of valve lift characteristics in the form of a combination of a cam lift pattern realized by the main lift portion and a cam lift pattern realized by the sublift portion. Therefore, various engine performances required according to the running conditions of the engine can be fully satisfied by the valve characteristics.
