Abstract
Brennkraftmaschine, insbesondere eines Kraftfahrzeuges, mit einer Zylinderkopfhaube (10) und einem Unterdruckspeicher, dadurch gekennzeichnet, daß der Unterdruckspeicher (18, 20) in die Zylinderkopfhaube (10) integriert ist.Internal combustion engine, in particular a motor vehicle, with a cylinder head cover (10) and a vacuum reservoir, characterized in that the vacuum reservoir (18, 20) in the cylinder head cover (10) is integrated.
Description
Die Erfindung betrifft eine Brennkraftmaschine, insbesondere eines Kraftfahrzeuges, mit einer Zylinderkopfhaube und einem Unterdruckspeicher, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to an internal combustion engine, in particular a motor vehicle, with a cylinder head cover and a vacuum reservoir, according to the preamble of claim 1.
Bei Brennkraftmaschinen ist es bekannt, einen während Schub- oder Leerlaufphasen der Brennkraftmaschine vorliegenden, niedrigen Ansaugdruck, der stromab einer Luftdrosselklappe herrscht, zum Erzeugen von Unterdruck in einem Unterdruckspeicher zu verwenden und diesen Unterdruck als Antriebsenergie für pneumatische Stellelemente für Fahrzeug- oder Motorausrüstung zu nutzen, wie beispielsweise Brems-, Kupplungsautomatik-, Türverriegelungs- oder Abgasrückführsysteme. Aus der
Der Erfindung liegt die Aufgabe zugrunde, eine Brennkraftmaschine der obengenannten Art bzgl. Bauraum und Montageaufwand zu verbessern.The invention has for its object to improve an internal combustion engine of the above type with respect to space and installation costs.
Diese Aufgabe wird erfindungsgemäß durch eine Brennkraftmaschine der o. g. Art mit den in Anspruch 1 gekennzeichneten Merkmalen gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen angegeben.This object is achieved by an internal combustion engine o. G. Art solved with the features characterized in claim 1. Advantageous embodiments of the invention are specified in the dependent claims.
Dazu ist es erfindungsgemäß vorgesehen, daß der Unterdruckspeicher in die Zylinderkopfhaube integriert ist.For this purpose, it is provided according to the invention that the vacuum reservoir is integrated in the cylinder head cover.
Dies hat den Vorteil, daß ein externer Unterdruckspeicher sowie die zugehörige Halterung im Motorraum entfallen kann, so daß sich eine erhebliche Bauraumeinsparung ergibt. Auch eine zusätzliche Montage des Unterdruckspeichers entfällt, da dieser automatisch gleichzeitig mit der Zylinderkopfhaube montiert wird.This has the advantage that an external vacuum reservoir and the associated bracket in the engine compartment can be omitted, so that there is a considerable space savings. An additional installation of the vacuum reservoir is omitted, since it is automatically mounted simultaneously with the cylinder head cover.
In einer bevorzugten Ausführungsform der Erfindung ist ein erstes Teil des Unterdruckspeichers einstückig mit der Zylinderkopfhaube ausgebildet und ein den Unterdruckspeicher vervollständigendes zweites, separates Teil an diesem ersten Teil befestigt ist.In a preferred embodiment of the invention, a first part of the vacuum reservoir is formed integrally with the cylinder head cover and a vacuum reservoir the second complete, separate part is attached to this first part.
Das einstückig mit der Zylinderkopfhaube ausgebildete erste Teil des Unterdruckspeichers ist beispielsweise auf einer von einem Zylinderkopf der Brennkraftmaschine abgewandten Außenseite der Zylinderkopfhaube ausgebildet und in vorteilhafter Weise mit dem ersten Teil mittels Schweißen verbunden.The integrally formed with the cylinder head cover first part of the vacuum accumulator is formed for example on a side facing away from a cylinder head of the engine outside of the cylinder head cover and connected in an advantageous manner to the first part by means of welding.
Weitere Merkmale, Vorteile und vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den abhängigen Ansprüchen, sowie aus der nachstehenden Beschreibung der Erfindung anhand der beigefügten Zeichnungen. Diese zeigen inFurther features, advantages and advantageous embodiments of the invention will become apparent from the dependent claims, and from the following description of the invention with reference to the accompanying drawings. These show in
