Abstract | The method involves adjusting an electromechanical actuator to actuate a cam profile switching mechanism, and operating the actuator at a first level without a valve transition. The actuator is operated at a second level without a valve transition in response to increased potential for valve transition. The actuator is operated at a third level inducing a valve transition, where the second level is provided between the first and third levels. The actuator is set to an inactive state in response to an engine operating condition.
Es werden Verfahren für eine verbesserte Steuerung von Ventilaktivierungs- bzw. -deaktivierungsmechanismen bereitgestellt. Ein beispielhaftes Verfahren umfasst das Einstellen eines elektromechanischen Aktors zum Betätigen von Zylinderventildeaktivierungs- bzw. -aktivierungsmechanismen. Der Aktor wird basierend auf den Motorbetriebsbedingungen bei mehreren Werten betätigt. |
