Abstract
Description
Die Erfindung betrifft eine Brennkraftmaschine mit einer Ansaugleitung zur Zuführung der Ansaugluft zu den einzelnen Brennräumen, mit einer Abgasleitung zur Abführung der Abgase aus den Brennräumen und mit einer die Ansaugleitung und die Abgasleitung verbindenden Abgasrückführleitung.The The invention relates to an internal combustion engine with a suction line to the feeder the intake air to the individual combustion chambers, with an exhaust pipe to the exhaustion the exhaust gases from the combustion chambers and with a connecting the suction pipe and the exhaust pipe Exhaust gas recirculation line.
Eine
derartige Brennkraftmaschine ist aus der
Der Erfindung liegt die Aufgabe zugrunde, eine Brennkraftmaschine mit einer Abgasrückführleitung nach dem Oberbegriff des Anspruchs 1 so zu verbessern, dass die Abgasrückführleitung weitgehendst korrosionsgeschützt und bei einem guten Wärmeübergang wirtschaftlich herzustellen ist.Of the Invention is the object of an internal combustion engine with an exhaust gas recirculation line to improve according to the preamble of claim 1 so that the Exhaust gas recirculation line largely protected against corrosion and with a good heat transfer is economical to produce.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass die Abgasrückführleitung eine Innen- und/oder Außenverrippung aufweist und aus Grauguss hergestellt ist.According to the invention this Task solved by that the exhaust gas recirculation line an internal and / or external ribbing and is made of gray cast iron.
Grauguss eignet sich vorzüglich für korrosionsbelastete Anwendungen und hat durch eine erfindungsgemäße innen- und/oder Außenverrippung einen guten Wärmeübergang bei wirtschaftlicher Herstellungsweise.cast iron is excellent for corrosion-stressed Applications and has by an inventive inner and / or Außenverrippung a good heat transfer in economic production.
In bevorzugter Ausführungsform besteht die Außenverrippung aus sich in radialer Richtung erstreckenden und auf dem Außenumfang umlaufenden Rippenringen.In preferred embodiment exists the external ribbing extending in the radial direction and on the outer circumference circumferential rib rings.
Die Innenverrippung besteht vorteilhafterweise aus in Längsrichtung hintereinander angeordneten Rippenringen, wobei diese Rippenringe jeweils aus einzelnen sich in Längsrichtung und radial nach innen erstreckenden Rippen besteht.The Internal ribbing is advantageously made in the longitudinal direction successively arranged ribbed rings, said ribbed rings each from individual in the longitudinal direction and radially inwardly extending ribs.
In weiterer vorteilhafter Ausgestaltung sind die Rippen eines Rippenringes zu den Rippen seines benachbarten Rippenringes versetzt angeordnet, wobei bevorzugt der Versatz den halben Abstand zwischen zwei benachbarten Rippen eines Rippenringes beträgt.In Another advantageous embodiment, the ribs of a rib ring arranged offset to the ribs of its adjacent rib ring, wherein Preferably, the offset is half the distance between two adjacent ones Ripping a rib ring is.
In einer vorteilhaften Ausführungsform besteht jeder Rippenring aus zehn bis zweiundzwanzig im gleichen Abstand auf dem Innenumfang angeordneten Rippen, wobei jeder Rippenring aus sechzehn im gleichen Abstand auf dem Innenumfang angeordneten Rippen besteht. Die Anzahl der Rippen und der Rippenringe kann von Brennkraftmaschine zu Brennkraftmaschine variieren und ist an die speziellen Erfordernisse eines jeden Einzelfalles anzupassen.In an advantageous embodiment Each rib ring consists of ten to twenty-two in the same Spaced ribs arranged on the inner circumference, each rib ring arranged from sixteen at the same distance on the inner circumference Ribs exists. The number of ribs and rib rings can vary from Internal combustion engine to internal combustion engine varies and is attached to the to adapt to the specific requirements of each individual case.
Vorteilhafterweise ist die Brennkraftmaschine eine selbstzündende luftgekühlte Brennkraftmaschine.advantageously, the internal combustion engine is a self-igniting air-cooled internal combustion engine.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind der Zeichnungsbeschreibung zu entnehmen, in der die in den Figuren dargestellten Ausführungsbeispiele näher beschrieben sind. Es zeigen:Further advantageous embodiments of the invention are the drawing description to take in the illustrated in the figures embodiments described in more detail are. Show it:

Bevorzugt wird diese Abgasrückführleitung aus Grauguss mit einer Innen- und/oder Außenverrippung bei selbstzündenden Brennkraftmaschinen (Dieselmotoren), insbesondere bei luftgekühlten Brennkraftmaschinen eingesetzt. Die Brennkraftmaschine weist ein Einspritzsystem auf, das mit einem mechanischen Regler ausgestattet ist, so dass die Brennkraftmaschine insgesamt keine elektronische Steuereinrichtung benötigt.Prefers this exhaust gas recirculation line is off Gray cast iron with internal and / or external ribbing for self-igniting Internal combustion engines (diesel engines), in particular in air-cooled internal combustion engines used. The internal combustion engine has an injection system, which is equipped with a mechanical regulator so that the internal combustion engine no electronic control device needed.
