Description
Die Erfindung betrifft einen Verbrennungsmotor für ein Motorrad und ein Motorrad mit einem Verbrennungsmotor.The invention relates to an internal combustion engine for a motorcycle and a motorcycle with an internal combustion engine.
Verbrennungsmotoren für ein Motorrad, die eine Ansaugleitung, eine Abgasleitung und ein Getriebegehäuse für ein Getriebe umfassen, sind grundsätzlich bekannt.Internal combustion engines for a motorcycle including an intake pipe, an exhaust pipe, and a transmission housing for a transmission are basically known.
Der erfindungsgemäße Verbrennungsmotor für ein Motorrad umfasst eine Ansaugleitung, eine Abgasleitung, eine Abgasrückführung und ein Getriebegehäuse für ein Getriebe, wobei ein erstes Ende der Abgasrückführung mit der Abgasleitung und ein zweites Ende der Abgasrückführung mit der Ansaugleitung zum Rückführen von Abgas aus der Abgasleitung in die Ansaugleitung verbunden ist, und die Abgasrückführung abschnittsweise durch das Innere des Getriebegehäuses oder am Getriebegehäuse entlang geführt ist.The internal combustion engine for a motorcycle according to the invention comprises an intake pipe, an exhaust pipe, an exhaust gas recirculation and a transmission housing for a transmission, wherein a first end of the exhaust gas recirculation with the exhaust pipe and a second end of the exhaust gas recirculation with the intake pipe for returning exhaust gas from the exhaust pipe into the intake pipe is connected, and the exhaust gas recirculation is guided in sections through the interior of the transmission housing or the transmission housing along.
Die Erfindung ermöglicht es, bei geringem Raumangebot eine Abgasrückführung in einem Verbrennungsmotor vorzusehen. Hierfür wird die Abgasrückführung zumindest abschnittsweise durch das Getriebegehäuse oder am Getriebegehäuse entlang geführt. Bevorzugt ist, dass in diesem Abschnitt die Abgasrückführung im Getriebegehäuse nach Innen baut, also entlang einer Innenfläche des Getriebegehäuses verläuft, beispielsweise in Form einer bereichsweisen doppelwandigen Ausbildung des Getriebegehäuses. Der erfindungsgemäße Verbrennungsmotor eignet sich damit insbesondere für Motorräder oder Kleinstfahrzeuge.The invention makes it possible to provide an exhaust gas recirculation in an internal combustion engine with a small amount of space. For this purpose, the exhaust gas recirculation is performed at least in sections through the gear housing or the gear housing along. It is preferred that the exhaust gas recirculation in the transmission housing builds inward in this section, that extends along an inner surface of the transmission housing, for example in the form of a region-wise double-walled design of the transmission housing. The internal combustion engine according to the invention is thus particularly suitable for motorcycles or micro vehicles.
Es Weiteren ermöglicht die Erfindung, über die Abgasrückführung zurückgeführtes Abgas über eine bestehende Kühlung zu kühlen. Eine separate Kühlung ist nicht notwendig. In einer bevorzugten Ausführungsform wird eine Motorkühlung für die Kühlung des zurückgeführten Abgases verwendet, in dem die Kühlung zumindest abschnittsweise mit der Abgasrückführung verbunden ist.Furthermore, the invention makes it possible to cool exhaust gas recirculated via the exhaust gas recirculation via existing cooling. A separate cooling is not necessary. In a preferred embodiment, an engine cooling is used for the cooling of the recirculated exhaust gas, in which the cooling is at least partially connected to the exhaust gas recirculation.
Der Verbrennungsmotor ist vorzugsweise ein Ottomotor.The internal combustion engine is preferably a gasoline engine.
Ein erfindungsgemäßes Motorrad oder Kleinstfahrzeug umfasst einen erfindungsgemäßen Verbrennungsmotor.An inventive motorcycle or miniature vehicle comprises an internal combustion engine according to the invention.
Die abhängigen Ansprüche beschreiben weitere vorteilhafte Ausführungsformen der Erfindung.The dependent claims describe further advantageous embodiments of the invention.
Bevorzugte Ausführungsbeispiele werden anhand der folgenden Figur näher erläutert.Preferred embodiments will be explained in more detail with reference to the following figure.

Die Abgasrückführung
Der Verbrennungsmotor ist in diesem Ausführungsbeispiel ein Ottomotor. Alternativ ist es möglich, dass der Verbrennungsmotor ein Dieselmotor ist.The internal combustion engine is a gasoline engine in this embodiment. Alternatively, it is possible that the internal combustion engine is a diesel engine.
