Abstract
Description
Die Erfindung betrifft einen Zylinderkopf für eine wassergekühlte Brennkraftmaschine mit den Merkmalen aus dem Oberbegriff des Patentanspruches 1.The The invention relates to a cylinder head for a water-cooled internal combustion engine with the features of the preamble of claim 1.
Sie
geht von der deutschen Offenlegungsschrift
Durch die vorgeschlagene Ausgestaltung werden die auslassseitigen Ventilsitzbereiche sehr gut gekühlt, was jedoch auch zu einer starken Abkühlung des Abgases während der Warmlaufphase der Brennkraftmaschine führt. Nachteilig hierbei ist das verspätete Anspringen des Katalysators, bzw. der verspätete Beginn der Abgasreinigung.By the proposed embodiment will be the outlet side valve seat areas very well cooled, which also leads to a strong cooling of the exhaust gas during the Warm-up phase of the internal combustion engine leads. The disadvantage here is the belated one Starting the catalyst, or the delayed start of the exhaust gas purification.
Aufgabe der vorliegenden Erfindung ist es, eine Maßnahme aufzuzeigen, wie für einen gattungsgemäßen Zylinderkopf eine gute Kühlung erzielbar ist, ohne ein frühes Anspringen des Katalysators zu verhindern.task The present invention is to show a measure as for a generic cylinder head a good cooling achievable without an early one To prevent the onset of the catalyst.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale im kennzeichnenden Teil des Patentanspruchs 1 dadurch gelöst, dass der Strömungsquerschnitt des Kühlmittelkanals in Strömungsrichtung des Kühlmittels von der Einströmöffnung bis zum Sammelkanal im Wesentlichen konstant bleibt.These The object is achieved by the Characteristics in the characterizing part of patent claim 1 achieved in that the flow cross section of the coolant channel in the flow direction of the coolant from the inlet opening to the Collection channel remains substantially constant.
Durch die vorgeschlagene Ausgestaltung gemäß Patentanspruch 2 wird eine sehr gezielte und gleichmäßige Kühlung des Zylinderkopfes erreicht. Aufgrund der geringen Umspülung der Einlasskanäle wird die Ansaugluft nur minimal aufgeheizt, womit der Füllgrad der Brennkraftmaschine verbessert wird, d.h. Leistung und Drehmoment der Brennkraftmaschine werden gesteigert.By the proposed embodiment according to claim 2 becomes a very targeted and even cooling of the Cylinder head reached. Due to the low flushing of the Inlet channels is the intake air heated only minimally, whereby the degree of filling of the Internal combustion engine is improved, i. Power and torque the internal combustion engine are increased.
Durch die Ausgestaltung gemäß Patentanspruch 3 wird der Strömungswiderstand wesentlich verringert, wodurch die Kühlmittelpumpe kleiner dimensioniert werden kann, was wiederum zu einer Kraftstoffersparnis führt.By the embodiment according to claim 3 becomes the flow resistance significantly reduced, whereby the coolant pump dimensioned smaller which in turn leads to fuel savings.
Bei der Ausgestaltung gemäß Patentanspruch 4 wird in vorteilhafter Weise auch die Gaswechselventilschaftführung mitgekühlt.at the embodiment according to claim 4, the gas exchange valve stem guide is advantageously also cooled.
Im Folgenden ist die Erfindung anhand zwei bevorzugter Ausführungsbeispiele in zwei Figuren näher erläutert.in the The following is the invention with reference to two preferred embodiments closer in two figures explained.
