VENTILTRIEB FÜR VERBRENNUNGSMOTOR

摘要

There is provided a valve gear (11) with a motor (12), a cam mechanism (14) which converts a rotational motion of the motor (12) into a linear motion of an intake valve (2) by a cam (21), and a motor control apparatus (30) which controls the motor (12) such that an acceleration characteristic during a lift of the intake valve (2) changes in correspondence to a rotation number of an internal combustion engine.
