Abstract

Die Erfindung betrifft eine Motorstaubremsvorrichtung einer 4-Takt-Hubkolbenbrennkraftmaschine, die je Zylinder wenigstens ein Einlassventil und zwei Auslassventile (2, 3) aufweist und gezielt auf diesen Motortyp abgestellt ist. Im Abgastrakt (9) ist eine zur Motorbremsung derart betätigbare Drosselvorrichtung (10) eingebaut, dass sich stromauf derselben im aufgestauten Abgas ein Abgasgegendruck aufbaut, der in Verbindung mit einer speziellen motorinternen Bremsvorrichtung (11) wirksam wird. Erfindungsgemäß ist die motorinterne Bremsvorrichtung (11) je Zylinder (1) nur einem (2) der beiden Auslassventile (2, 3) zugeordnet, das andere Auslassventil (3) dagegen ist herkömmlich gesteuert. Die motorinterne Bremseinrichtung (11) umfasst einen in der Ventilbrücke (20) eingebauten Steuerkolben (30), der von einem öldruckbeaufschlagten Steuerdruckraum (33) her und eventuell durch eine zusätzliche Steuerdruckfeder (32) in Richtung Auslassventil (2) gedrückt ist. Der Steuerdruckraum (33) ist an eine permanente Druckölversorgung angeschlossen und abhängig von der Bewegung bzw. Stellung der Ventilbrücke (20) über einen Entlastungskanal (37) entweder abgesperrt oder druckentlastet. Hierdurch ergibt sich während des Motorbremsens automatisch eine bestimmte Öffnungs- und Schließcharakteristik des Auslassventils (2) mit der Folge einer hohen Motorbremsleistung.
