Due to the configuration of the invention, a festiere embodiment of Gaswechseleinlass- and Gaswechselauslasskanäle is possible, whereby a higher power for the internal combustion engine can be achieved.
Description
Die Erfindung betrifft einen Zylinderkopf für eine fremdgezündete Brennkraftmaschine mit den Merkmalen aus dem Oberbegriff des Patentanspruchs 1.The The invention relates to a cylinder head for a spark-ignition internal combustion engine with the features of the preamble of claim 1.

Patentschrift
Die Anordnung von Kraftstoffinjektor und Zündeinrichtung zwischen den Gaswechselventilen bedingt jedoch einen relativ großen Gaswechselventilwinkel. Dies bedeutet, dass der Winkel, der von den Gaswechseleinlassventilen und den Gaswechselauslassventilen zueinander gebildet ist, relativ groß ist. Durch diese geometrische Ausgestaltung wird der Strömungswiderstand sowohl von der Ansaugluft einlassseitig als auch vom Abgas auslassseitig negativ beeinflusst. Hierdurch kann eine gattungsgemäße Brennkraftmaschine nicht die optimale Leistung erzielen.The Arrangement of fuel injector and ignition between the Gas exchange valves, however, requires a relatively large gas exchange valve angle. This means that the angle of the gas exchange inlet valves and the gas exchange outlet valves are formed relative to each other is great. By this geometric configuration of the flow resistance both the intake air inlet side and the exhaust gas outlet side negatively influenced. As a result, a generic internal combustion engine not achieve the optimal performance.
Aufgabe der vorliegenden Erfindung ist es, eine Maßnahme aufzuzeigen, mit der die Leistung einer gattungsgemäßen Brennkraftmaschine verbessert werden kann.task The present invention is to show a measure with which the performance of a generic internal combustion engine can be improved.
Diese Aufgabe wird durch die Merkmale im kennzeichnenden Teil des Patentanspruchs 1 gelöst.These The object is achieved by the features in the characterizing part of the claim 1 solved.
In vorteilhafter Weise kann durch die erfindungsgemäße Ausgestaltung der Ventilwinkel zwischen den Gaswechseleinlassventilen und den Gaswechselauslassventilen verringert werden. Somit können die Gaswechseleinlass- und Gaswechselauslasskanäle „steiler" ausgelegt werden, wodurch die Strömungsverluste in den Kanälen minimiert werden. Somit können die Leistung, bzw. der Wirkungsgrad der Brennkraftmaschine verbessert werden. Durch die erfindungsgemäße Ausgestaltung mit der Hülse ist ein kompakter, relativ schmal bauender Zylinderkopf erzielt, da der Kraftstoffinjektor in die Hülse im Zylinderkopf eingefädelt werden kann, da zwischen dem Kraftstoffinjektor und der Zündeinrichtung in der Höhe der Ventiltriebe kein Zylinderkopfmaterial angeordnet ist. Trotz der zentralen Lage des Kraftstoffinjektors und der Zündeinrichtung baut der erfindungsgemäß ausgestaltete Zylinderkopf nicht breiter als ein konventioneller Zylinderkopf.In Advantageously, by the inventive design of the valve angle between the gas exchange inlet valves and the gas exchange outlet valves be reduced. Thus, you can the gas exchange inlet and Gaswechselauslasskanäle be designed "steeper", causing the flow losses in the channels be minimized. Thus, you can the performance, or the efficiency of the internal combustion engine improved become. Due to the inventive design with the sleeve is achieved a compact, relatively narrow cylinder head, because the fuel injector are threaded into the sleeve in the cylinder head can, as between the fuel injector and the ignition device in the height the valve trains no cylinder head material is arranged. In spite of the central position of the fuel injector and the ignition device builds the inventively designed Cylinder head no wider than a conventional cylinder head.
Die Ausgestaltung gemäß Patentanspruch 2 ermöglicht es, zumindest einlassseitig einen hubvariablen Ventiltrieb anzuordnen, wobei auch in diesem Fall die Baubreite des Zylinderkopfes nicht größer ist als im Stand der Technik. Somit kann die Einbaubreite der Brennkraftmaschine im Gesamtfahrzeug beibehalten werden.The Embodiment according to claim 2 allows it, at least on the inlet side to arrange a variable-stroke valve drive, although in this case the width of the cylinder head not is greater than in the prior art. Thus, the installation width of the internal combustion engine be maintained in the entire vehicle.
Die Ausgestaltung gemäß Patentanspruch 3 ermöglicht eine besonders kompakte Komponentenanordnung im Zylinderkopf.The Embodiment according to claim 3 allows a particularly compact component arrangement in the cylinder head.
Die Ausgestaltung gemäß Patentanspruch 4 ist eine besonders bevorzugte Ausführungsvariante.The Embodiment according to claim 4 is a particularly preferred embodiment.
Die Ausgestaltungen gemäß der Patentansprüche 5 und 6 unterstützen nochmals die besonders kompakte Komponentenanordnung im Zylinderkopf.The Embodiments according to the claims 5 and 6 support again the particularly compact component arrangement in the cylinder head.
Die Ausgestaltung gemäß Patentanspruch 7 ist wiederum eine besonders bevorzugte Ausführungsvariante.The Embodiment according to claim 7 is again a particularly preferred embodiment.
Im Folgenden ist die Erfindung anhand eines bevorzugten Ausführungsbeispieles in einer einzigen Figur näher erläutert.in the The invention is based on a preferred embodiment in a single figure closer explained.
