Description

Die Erfindung bezieht sich auf einen Zylinderkopf für eine wassergekühlte Brennkraftmaschine nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a cylinder head for a water-cooled Internal combustion engine according to the preamble of patent claim 1.

Es ist ein Zylinderkopf für eine ventilgesteuerte Brennkraftmaschine mit Wassserkühlung bekannt - EP 0088 157 A1-, welcher Zylinderkopf Maßnahmen zur Verringerung der thermischen Belastung umfaßt. Hierfür ist ein düsenartiger Hauptwasserübertritt vorgesehen, der eine zwischen Gaswechselkanälen wirkende Strömung erzeugt.It is a cylinder head for a valve controlled internal combustion engine Water cooling known - EP 0088 157 A1-, which cylinder head measures for Includes thermal stress reduction. This is a nozzle type Main water transfer provided, the one acting between gas exchange channels Flow generated.

Die EP 0353988 A1 zeigt in Fig.3 einen Zylinderkopf, der wassergekühlt ist und eine Heißstelle im Bereich einer Wand des Zylinderkopfs aufweist. Die Heißstelle erstreckt sich zwischen einer zentralen Zündkerze und einem Brennraum.EP 0353988 A1 shows in FIG. 3 a cylinder head that is water-cooled and one Has hot spot in the area of a wall of the cylinder head. The hot spot extends between a central spark plug and a combustion chamber.

Schließlich behandelt die US 2,305,457 einen wassergekühlten Zylinderkopf mit Kühlkanälen, die um Auslaßventile herumgeführt sind. Diese Kühlkanäle weisen benachbart den Auslaßventilen Wandungen auf, die mittels über Sprühdüsen verteiltes Kühlmedium gekühlt werden.Finally, US 2,305,457 also treats a water-cooled cylinder head Cooling channels that are routed around exhaust valves. These cooling channels point adjacent to the outlet valves on walls, which is distributed by means of spray nozzles Cooling medium to be cooled.

Aufgabe der Erfindung ist es, einen Kühlkanal eines Zylinderkopfs einer Brennkraftmaschine derart zu gestalten, daß vor allem ausgeprägte Heißstellen des Zylinderkopfs über den Kühlkanal mit strömendem Kühlwasser versorgt werden.The object of the invention is a cooling channel of a cylinder head To design the internal combustion engine such that, above all, pronounced hot spots of the Cylinder head are supplied with flowing cooling water via the cooling channel.

Nach der Erfindung wird diese Aufgabe durch die Merkmale des Patentanspruchs 1 gelöst. Weitere, die Erfindung ausgestaltende Merkmale sind in den Unteransprüchen enthalten. According to the invention, this object is achieved by the features of claim 1 solved. Further features embodying the invention are in the subclaims contain.

Die mit der Erfindung hauptsächlich erzielten Vorteile sind darin zu sehen, daß die Steuervorkehrungen im Kühlkanal eines aus einer Leichtmetallegierung bestehenden Zylinderkopfs eine gezielte Kühlwasserströmung im Bereich der Heißstelle bewirken d.h. an der Wandung des Kühlkanals, die sich beispielsweise zwischen einer zentralen Zündkerze und einem Brennraum erstreckt. Die Steuervorkehrungen sind dann besonders wirksam, wenn sie benachbart der Heißstelle in dem Kühlkanal vorgesehen sind, in dem das Kühlwassers als Querstrom von der Auslaßseite zur Einlaßseite hin fließt. Die Steuervorkehrungen werden pro Brennraum durch eine Leitrippe und Sperrippen im Kühlkanal gebildet. Sie bewirken einen gezielten Strom des Kühlwassers an die Heißstelle und reduzieren dort das Risiko einer temperaturbedingten Überbeanspruchung. Dies wiederum ermöglicht zum einen, daß bei der konstruktiven Auslegung eines Zylinderkopfs Standardwerkstoffe - AlSi 10 oder AlSi 7 - verwendet werden können und zum anderen, daß der Ausschuß, der gerade bei Zylinderköpfen von Brennkraftmaschine besonders kostenträchtig ist, deutlich reduziert wird.The main advantages achieved with the invention are that the Control measures in the cooling duct of a light metal alloy Cylinder head cause a targeted cooling water flow in the area of the hot spot i.e. on the wall of the cooling channel, which is, for example, between a central Spark plug and a combustion chamber extends. The tax arrangements are then particularly effective when provided adjacent to the hot spot in the cooling channel are in which the cooling water as a cross flow from the outlet side to the inlet side flows. The control arrangements are made for each combustion chamber by a guide rib and Locking ribs formed in the cooling channel. They cause a targeted flow of the cooling water to the hot spot and reduce the risk of a temperature-related Overuse. On the one hand, this enables the constructive Design of a cylinder head using standard materials - AlSi 10 or AlSi 7 and on the other hand, that the committee that is currently working on cylinder heads of internal combustion engines is particularly costly, is significantly reduced.

Der Zylinderkopf 2 ist pro Zylinder mit zwei Einlaßventilen und zwei Auslaßventilen - nicht dargestellt - versehen, die mit ihren Ventiltellern mit Ventilsitzen 5,6 und 7,8 zusammenwirken. Die Ventilsitze 5,6 weisen einen größeren Durchmesser auf als die Ventilsitze 7,8, wobei die Ventilsitze 5,6 mit den Einlaßventile zusammenwirken; die Ventilsitze 7,8 mit den Auslaßventilen. Außerdem sind die Ventilsitze 5 und 6 sowie die Ventilsitze 7 und 8 mit ihren zugehörigen Einlaßventilen und Auslaßventilen beiderseits einer Querebene A - A angeordnet, die im rechten Winkel zu einer Mittellängsebene B-B des Zylinderkopfs verläuft. Über die Einlaßventile einer Einlaßseite 9 wird einem Brennraum 10 ein Kraftstoffluftgemisch - Saugrohreinspritzung - zugeführt, das mittels einer Zündkerze 11 entzündet wird und danach durch die Auslaßventile einer Auslaßseite 12 in eine nicht gezeigte Abgasanlage gelangt. Die in eine Gewindebohrung 13 des Zylinderkopfs 2 eingedrehte Zündkerze 11 verläuft in einer Mittellängsebene C - C eines Zylinders 14 - oder mit geringem Abstand dazu -, d.h. sie weist eine zentrale Lage im Brennraum 10 auf.A multi-cylinder internal combustion engine 1- Otto type - with water cooling includes in the area shown a cylinder head 2 and a cylinder housing 3, which a light metal alloy and composed in a parting plane 4 are. The cylinder head 2 is per cylinder with two intake valves and two exhaust valves - Not shown - provided that with their valve plates with valve seats 5.6 and 7.8 work together. The valve seats 5,6 have a larger diameter than that Valve seats 7,8, the valve seats 5,6 interacting with the inlet valves; the Valve seats 7,8 with the outlet valves. In addition, the valve seats 5 and 6 and the Valve seats 7 and 8 with their associated intake valves and exhaust valves on both sides a transverse plane A - A arranged at right angles to a central longitudinal plane B-B of the cylinder head. About the inlet valves of an inlet side 9 is one Combustion chamber 10 a fuel-air mixture - intake manifold injection - supplied by a spark plug 11 is ignited and then through the exhaust valves Exhaust side 12 enters an exhaust system, not shown. The one Threaded bore 13 of the cylinder head 2 inserted spark plug 11 runs in one Central longitudinal plane C - C of a cylinder 14 - or at a short distance from it -, i.e. she has a central location in the combustion chamber 10.

In dem mit Kühlwasser gekühlten Zylinderkopf 2 ist pro Brennraum 10 bzw. Zylinder 14 ein Kühlkanal 15 vorgesehen, der von einem ersten Längskanal 16 des Zylindergehäuses 3 aus mit besagtem Kühlwasser versorgt wird. Der Längskanal 16 begrenzt mit einer Zylinderwand 17 eine Zylinderlaufbüchse 18 des Zylinders 14, und zwar örtlich unter Bildung eines Ringraums 19, der zum Eintritt von Kühlwasser über eine Öffnung 20 mit dem Längskanal 16 verbunden ist. Das Kühlwasser strömt von der Auslaßseite 12 vom Längskanal 16 kommend über den Kühlkanal 15 zu der Einlaßseite 9 hin - ein Querstrom im Zylinderkopf 2 bewirkender Kühlkanal 15 - und wird durch einen zweiten Längskanal 21 des Zylinderkopfs 2 abgeführt.In the cylinder head 2 cooled with cooling water there is 10 or cylinders per combustion chamber 14, a cooling channel 15 is provided, which of a first longitudinal channel 16 Cylinder housing 3 is supplied with said cooling water. The longitudinal channel 16 delimits with a cylinder wall 17 a cylinder liner 18 of the cylinder 14, and locally with formation of an annular space 19, which leads to the entry of cooling water an opening 20 is connected to the longitudinal channel 16. The cooling water flows from the outlet side 12 coming from the longitudinal channel 16 via the cooling channel 15 to the Intake side 9 out - a cross flow in the cylinder head 2 causing cooling channel 15 - and is discharged through a second longitudinal channel 21 of the cylinder head 2.

Im Kühlkanal 15 ergibt sich beim Betrieb der Brennkraftmaschine 1 durch Strahlwäme des Brennraums 10 eine Heißstelle 22 an einer Wand 23, die die Gewindebohrung 13 und den Brennraum 10 begrenzt. Um eine gezielte Kühlung dieser Heißstelle 22 zu gewährleisten, sind im Kühlkanal 15 des Zylinderkopfs 2 auf der Auslaßseite 12 Steuervorkehrungen 24 angeordnet, mit denen der Kühlwasserstrom derart gezielt an der Heißstelle 22 vorbeigeführt wird, daß die thermische Belastung der Wand 23 des Zylinderkopfs 2 reduziert wird. Die Steuervorkehrungen 24 sind bei 25, also benachbart der Heißstelle 22 wirksam und werden durch eine Leitrippe 26 gebildet. Diese Leitrippe 26 besitzt eine Umlenkkante 27, die einen mit strichpunktierten dargestellten, beschleunigten Kühlwasserstrom Ks erzeugt. Damit ein gut wirksamer Kühlwasserstom mit der Leitrippe 26 bewerkstelligt wird, erstreckt sich letztere in der Querebene A - A zwischen den Auslaßventilen. Darüber hinaus umfassen die Steuervorkehrungen 24 im Kühlkanal 15 zwei - in Querrichtung A - A gesehen - mit Abstand zueinander angeordnete Sperrippen 28,29, die symmetrisch beiderseits der Leitrippe 26 verlaufen. Schließlich ist im Kühlkanal 15 eine Brennraumstütze 30 angeordnet, in der eine Bohrung 31 vorgesehen ist. Diese Bohrung 31 trägt dazu bei, daß der Kühlwasserstrom grade im Bereich der Heißstelle 22 effizient ist.In the cooling duct 15 results from radiant heat during operation of the internal combustion engine 1 the combustion chamber 10 a hot spot 22 on a wall 23, the threaded hole 13th and limits the combustion chamber 10. In order to specifically cool this hot spot 22 ensure are in the cooling channel 15 of the cylinder head 2 on the exhaust side 12th Control arrangements 24 are arranged with which the cooling water flow in such a targeted manner the hot spot 22 is passed that the thermal load on the wall 23 of the Cylinder head 2 is reduced. Controls 24 are at 25, so adjacent hot spot 22 and are formed by a guide rib 26. This guide rib 26 has a deflection edge 27, one with dash-dotted lines shown, accelerated cooling water flow Ks generated. So that a good effective Cooling water flow is accomplished with the guide rib 26, the latter extends in the Transverse plane A - A between the exhaust valves. In addition, the Control arrangements 24 in the cooling channel 15 two - seen in the transverse direction A - A - with Distance from each other locking ribs 28, 29, which are symmetrical on both sides of the Guide rib 26 run. Finally, there is a combustion chamber support 30 in the cooling duct 15 arranged in which a bore 31 is provided. This bore 31 helps that the cooling water flow is efficient in the area of the hot spot 22.
