摘要： PROBLEM TO BE SOLVED: To prevent a hunting phenomenon of a control shaft 12 at the start of an engine with large valve system friction.
SOLUTION: A lift/operation angle variable mechanism is provided which can continuously vary the lift characteristics of an intake valve (or an exhaust valve) according to the rotational position of the control shaft. In a fast idle operation region D2 and the like, a command signal (DUTY) to a control shaft actuator is calculated by a feedback control mode M2 based on the deviation between a detected value and a target value of the rotational position of the control shaft. However, in a transitional period D1 from a first combustion to a complete combustion during which rotational speed increases, a start-up control mode M1 is used and the oscillation of the command signal is lowered compared to the feedback control mode M2.
