Abstract
Description
Die Erfindung betrifft eine Brennkraftmaschine mit Abgasrückführung nach dem Oberbegriff des Anspruchs 1.The The invention relates to an internal combustion engine with exhaust gas recirculation the preamble of claim 1.
Die Rückführung von Abgas in den Ansaugtrakt einer Brennkraftmaschine zur Reduzierung von Schadstoffemissionen ist allgemein bekannt. Für eine solche Abgasrückführung werden verschiedene Abgasleitungen und Kühleinrichtungen benötigt, für die bei modernen Brennkraftmaschinen häufig nicht genug Bauraum zur Verfügung steht.The Repatriation of Exhaust gas in the intake tract of an internal combustion engine for reduction Pollutant emissions are well known. For such Be exhaust gas recirculation various exhaust pipes and cooling equipment needed for the modern internal combustion engines frequently not enough space available stands.

Ausgehend von dem vorgenannten Stand der Technik ist es eine Aufgabe der vorliegenden Erfindung eine Brennkraftmaschine mit Abgasrückführung vorzusehen, die einen kompakten Aufbau ermöglicht. In einer Weiterbildung soll auch eine Kühlung bzw. Vorkühlung des Abgasstroms in kompakter Weise möglich sein.outgoing It is an object of the present invention from the aforementioned prior art Invention to provide an internal combustion engine with exhaust gas recirculation, a allows compact construction. In a further development, a cooling or pre-cooling of the Exhaust gas flow in a compact manner possible be.
Diese Aufgabe wird durch eine Brennkraftmaschine mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen und Ausgestaltungen der Erfindung sind Gegenstand der abhängigen Ansprüche.These Task is by an internal combustion engine with the characteristics of Claim 1 solved. Advantageous developments and refinements of the invention are Subject of the dependent claims.
Die erfindungsgemäße Brennkraftmaschine weist eine Abgasrückleitung zur Rückführung des Abgases zur Ansaugseite der Brennkraftmaschine auf, wobei wenigstens ein Teil der Abgasrückleitung in einem Steuergehäusedeckel der Brennkraftmaschine integriert ist.The inventive internal combustion engine has an exhaust gas return line for the return of the exhaust gas to the intake side of the internal combustion engine, wherein at least one Part of the exhaust gas return line in a timing case cover the internal combustion engine is integrated.
Die Abgasrückleitung kann so bauraumsparend und kostengünstig in den Steuergehäusedeckel integriert werden. Ausfallträchtige und schwer zugängliche Schnittstellen von Rohrleitungen für das Abgas und ein Kühlmittel können auf diese Weise vermieden werden.The Exhaust gas recirculation line Can be so space-saving and inexpensive integrated into the timing case cover become. failure Pregnant and hard to reach Interfaces of pipes for the exhaust gas and a coolant can avoided in this way.
Vorzugsweise ist in dem Steuergehäusedeckel auch ein Kühlmittelraum integriert, der mit der Abgasrückleitung in thermischem Kontakt steht. Auf diese Weise erfolgt eine Kühlung bzw. Vorkühlung des Abgasrückstroms in dem Steuergehäusedeckel, sodass ein separater AGR-Kühler kleinerer Kapazität benutzt oder auf einen separaten AGR-Kühler ganz verzichtet werden kann.Preferably is in the timing case cover also a coolant room integrated, with the exhaust gas return is in thermal contact. In this way, a cooling or Pre-cooling of the EGR flow in the timing case cover so that a separate EGR cooler smaller capacity used or on a separate EGR cooler can be dispensed with completely.
In einer Ausgestaltung der Erfindung sind der Steuergehäusedeckel und die Abgasrückleitung in kostengünstiger Weise als ein integrales Gussteil ausgebildet. Vorzugsweise ist der Steuergehäusedeckel zumindest im Bereich der Abgasrückleitung hier zur Reduzierung der Oberflächentemperatur außenseitig mit einer thermischen Isolierung versehen, insbesondere beschichtet.In An embodiment of the invention, the control housing cover and the exhaust gas return in a cost effective manner formed as an integral casting. Preferably, the timing cover is at least in the area of exhaust gas recirculation here to reduce the surface temperature externally provided with a thermal insulation, in particular coated.
Obige sowie weitere Merkmale und Vorteile der Erfindung werden aus der nachfolgenden Beschreibung eines bevorzugten, nicht-einschränkenden Ausführungsbeispiels der Erfindung unter Bezugnahme auf die beiliegenden Zeichnungen besser verständlich.
