Abstract
Brennkraftmaschine mit mindestens zwei Ventilgruppen, die unabhängig voneinander durch jeweils ein Schaltelement (4a) umschaltbare Betriebsmodi aufweisen,
dadurch gekennzeichnet, dass
das jeweils eine Schaltelement (4a) durch einen gemeinsamen Ansteuerpfad (5a) beaufschlagbar ist,
wobei die Anzahl der Ansteuerpfade (5a) kleiner ist als die Anzahl der mit einem gemeinsamen Modus betriebenen Ventilgruppen und es sich bei dem Ansteuerpfad (5a) um eine elektrische Leitung handelt und es sich bei dem Schaltelement (4a) um ein elektrisches Schaltelement (4a) handelt und die an den gemeinsamen Ansteuerpfad (5a) angeschlossenen elektrischen Schaltelemente (4a) durch Strommodulation bzw. Spannungsmodulation unabhängig ansteuerbar sind.
Internal combustion engine with at least two valve groups, which have operating modes that can be switched independently of one another by means of a switching element (4a),
characterized in that
each switching element (4a) can be acted upon by a common control path (5a),
wherein the number of control paths (5a) is smaller than the number of valve groups operated with a common mode and the control path (5a) is an electrical line and the switching element (4a) is an electrical switching element (4a) and the electrical switching elements (4a) connected to the common control path (5a) can be controlled independently by current modulation or voltage modulation.

Zum allgemeinen technischen Hintergrund wird noch auf die
Der Erfindung liegt die Aufgabe zugrunde, eine Brennkraftmaschine derart auszubilden, dass bei einer hohen Betriebssicherheit sowohl Bauraum bzw. Bauteile als auch Kosten eingespart werden können.The invention is based on the object of designing an internal combustion engine in such a way that both installation space and components as well as costs can be saved while maintaining a high level of operational reliability.
Diese Aufgabe wird erfindungsgemäß durch den Gegenstand des Patentanspruchs 1 gelöst.This object is achieved according to the invention by the subject matter of
Ein wesentlicher Vorteil der Erfindung besteht darin, dass die Anzahl der Ansteuerpfade und somit auch der Endstufen kleiner ist als die Anzahl der mit einem gemeinsamen Modus betriebenen Ventilgruppen, wodurch die störanfälligen und kostenintensiven Ansteuerpfade und Endstufen auf ein notwendiges Minimum beschränkt bleiben.A significant advantage of the invention is that the number of control paths and thus also of output stages is smaller than the number of valve groups operated with a common mode, whereby the fault-prone and cost-intensive control paths and output stages are limited to a necessary minimum.
Die Anzahl der Hydraulikleitungen kann außerhalb der Erfindung deutlich reduziert werden, weil die an einem gemeinsamen Ansteuerpfad angeschlossenen hydraulischen Schaltelemente durch Druckmodulation unabhängig ansteuerbar sind.The number of hydraulic lines can be significantly reduced outside the invention because the hydraulic switching elements connected to a common control path can be controlled independently by pressure modulation.
Bei einer Verwendung von mechanischen Schaltelementen kann die Anzahl der Aktuatoren zum Beaufschlagen dieser Schaltelemente außerhalb der Erfindung deutlich reduziert werden, weil die mechanischen Schaltelemente von einem gemeinsamen Aktuator mittels einer Kulisse individuell oder in Gruppen ansteuerbar sind.When using mechanical switching elements, the number of actuators for actuating these switching elements outside the invention can be significantly reduced because the mechanical switching elements can be controlled individually or in groups by a common actuator by means of a link.
