    • An upper surface of a head part of a valve lifter has a predetermined turn back portion at which, with a variable valve control device kept controlled to induce a maximum lift of an engine valve, a swing stroke of a rounded cam surface of a swing cam relative to the upper surface of the head part changes a traveling direction from a radially outward direction for opening the engine valve to a radially inward direction for closing the engine valve. An inlet end part of an oil hole formed in the head part is placed at a radially inside position of the upper surface other than a position where side edges of the rounded cam surface of the swing cam are in contact with the inlet end part of the oil hole when the rounded cam surface is placed in the vicinity of the turn back portion.

    • The apparatus calculates a torque that an induction motor generates while considering an iron loss even in a boosting state for exceeding the rated excitation. The calculation is based on a reference voltage value fed to an inverter for driving the induction motor, a q-axis current component and a d-axis current component resolved from a detected current of the induction motor on a rotating coordinate system, a primary resistance of the induction motor and a primary angular frequency. The apparatus includes an iron loss calculator that calculates the iron loss of the induction motor based on hysteresis characteristics of the stator core, a divider that divides the calculated iron loss by the primary angular frequency and an adder that calculates the generated torque by subtracting the result of the division from the torque calculated without considering the iron loss.
