    PATENTANSPRÜCHE
    L. Verbrennungsmotor mit mehreren Ansaugventilen, und sowohl einem ersten Luft-Ansaugkanal (7A), der normalerweise während allen Betriebszuständen benutzt wird und einem zweiten Luft-Ansaugkanal (7B), welcher hauptsächlich während hohen Motordrehzahlen oder hoher Last benutzt wird, wobei diese Kanäle mittels entsprechenden Ansaugventilen (6a, 6b) mit einer Brennkammer (5) verbunden sind, welche durch einen Zylinder (2), einen Zylinderkopf (3) und einen Kolben (4) definiert ist, dadurch ge kennzeichnet , daß der zweite Luft-Ansaugkanal (7b) mit einem Steuerventil (19) versehen ist, welches während niedriger Motordrehzahlen oder niedriger Motorbelastung geschlossen ist; und daß der erste Luft-Ansaugkanal (7a) und der zweite Luft-Ansaugkanal (7b) stromabwärts des Steuerventils (19) im Bereich der Ansaugventile (6a, 6b) mittels einer Verbindungsöffnung (7c) miteinander verbunden sind.
  2. 2. Verbrennungsmaschine.nach Anspruch 1, dadurch ge kennzeichnet , daß die beiden Luft-Ansaugkanäle (7a, 7b) an ihrer strömungsaufwärtigen Seite mit-
    einander unter Ausbildung eines Gehäuses (15) verbunden sind, daß in diesem Sammelgehäuse ein willkürlich betätigbares Drosselventil (16) vorgesehen ist, daß an der 5
    strömungsabwärtigen Seite dieses willkürlich betätigbaren Drosselventils zusätzlich zu dem in dem zweiten Luft-Ansaugkanal (7b) vorgesehenen Steuerventils (19) ein willkürlich betätigbares Ventil (18) vorgesehen ist, welches sich in Abhängigkeit von dem im ersten Luft-Ansaugkanal vorgesehenen Drosselventil öffnet und schließt, wobei sich jenes Steuerventil (19) während hoher Belastung der Brennkraftmaschine öffnet, und daß eine Verbindungseinrichtung (25 bis 29) zwischen dem Drosselventil (16) und dem willkürlich betätigbaren Ventils (18) vorgesehen ist, so daß sich bei Öffnung des Drosselventils (16) das willkürlich betätigbare Ventil vollständig öffnet bevor das Drosselventil weit geöffnet ist.

  5. 5. Verbrennungsmaschine nach einem der Ansprüche 1 bis 4, dadurch gekennzeichnet , daß die Verbindungsstange (25) einen ersten Hebel (22), welcher die Bewegungen des Drosselventils (16) überträgt, mit einem zweiten Hebel (24) verbindet, welcher an einer Welle des willkürlich betätigbaren Ventils (18) befestigt ist.
  6. 6. Verbrennungsmaschine nach Anspruch 5, dadurch ge-
    kennzeichnet , daß eine Nockeneinrichtung (21) an der Welle des Drosselventils (16) befestigt ist, wobei diese Nockeneinrichtung den ersten Hebel (22) beaufschlagt .
  7. 7- Verbrenhungsmaschine nach einem der Ansprüche 4 bis 6, dadurch gekennzeichnet , daß die Verbindungsstange (25) und die Hebel (22, 24) derart dimensioniert und angeordnet sind, daß sich das willkürlich betätigbare Ventil (18) zu öffnen beginnt, wenn das Drosselventil (16) weiter als in Leerlaufstellung geöffnet wird und daß das willkürlich betätigbare Ventil seine völlig .,_ offene Stellung erreicht, wenn das Drosselventil in etwa seine halboffene Stellung erreicht hat.
  8. 8. Verbrennungsmaschine nach Anspruch 2, dadurch ge kennzeichnet , daß das automatische Ventil
    on (19) an eine' Membraneinrichtung (28) angeschlossen ist, mit dei -i Hilfe dieses automatische Ventil während des Niedriglast-Betriebes der Verbrennungsmaschine geschlossen haltbar ist, während es unter schwererer Last öffnet, wobei der Öffnungsgrad in Übereinstimmung ist mit dem Belastungszustand.
  9. 9- Verbrennungsmaschine nach Anspruch 1, dadurch gekennzeichnet , daß die Verbindungsöffnung (7c) im wesentlichen die gleiche wirksame Fläche aufweist als der erste Kanal (7a).
  10. 10. Verbrennungsmaschine nach einem der Ansprüche 2 mit
    9, dadurch g e k e η ή ζ e i c h η e t ', daß die Verbindüngseiririchtung (25 bis 29) eine Totgangseinrichtung aufweist, mit deren Hilfe das Drosselventil (16) und das willkürlich betätigbare Ventil (18) miteinander verbunden sind.
