Description
Die Erfindung bezieht sich auf eine Wand eines Zulinderkurbelgehäuses nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a wall of a Zulinderkurbelgehäuses according to the preamble of
Es ist eine wassergekühlte Brennkraftmaschine mit einem Zylinderkopf bekannt,
Aus der
Eine ähnliche Ausführung einer Heißstellenkühlung für einem Zylinderkopf geht aus der
Es ist Aufgabe der Erfindung eine Kühlung von Heißstellen an einer Wand eines Zylinderkurbelgehäuses einer Brennkraftmaschine zu schaffen, die bei guter Funktion sich mit vertretbaren Mitteln realisieren lässt.It is an object of the invention to provide a cooling of hot spots on a wall of a cylinder crankcase of an internal combustion engine, which can be implemented with good means with reasonable means.
Erfindungsgemäß 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 solved by the features of
Die mit der Erfindung hauptsächlich erzielten Vorteile sind darin zu sehen, dass das in das Zylinderkurbelgehäuse integrierte Leitungssystem mit den Heißstellenleitungen eine gezielte Kühlung der Heißstellen sicherstellt, was gerade für Brennkraftmaschinen der Hochleistungsgattung von Bedeutung ist. Dies wird durch die Einspeisleitungen und die Umlenkleitungen, die in die Querkanäle des Zylinderkurbelgehäuses münden funktionsgerecht unterstützt. Die Heißstellenleitungen mit den Einspeisleitungen und den Umlenkleitungen lassen sich bei der Konzeption eines Zylinderkurbelgehäuses aufwandsarm realisieren. Eine vorzügliche Kühlung der Heißstellen ergibt sich, wenn die Heißstellenleitungen zumindest örtlich als Injektoren ausgebildet sind. Schließlich wird die Umsetzung der Einspeiseleitungen dadurch vereinfacht, wenn sie durch Schrägbohrungen verwirklicht werden, die über eine Anschlussöffnung des Zuführungskanals eingebracht werden.The advantages achieved by the invention are to be seen in the fact that the integrated into the cylinder crankcase piping system with the hot spot lines ensures targeted cooling of the hot spots, which is just for internal combustion engines of the high-performance category of importance. This is supported by the feed lines and the deflection lines, which open into the transverse channels of the cylinder crankcase functionally. The hot-spot lines with the feed lines and the deflection lines can be realized with little effort when designing a cylinder crankcase. An excellent cooling of the hot spots results when the hot spot lines are at least locally formed as injectors. Finally, the implementation of the feed lines is facilitated by being realized by inclined bores which are introduced via a connection opening of the feed channel.
In der Zeichnung wird ein Ausführungsbeispiel der Erfindung gezeigt, das nachstehend näher erläutert wird.In the drawing, an embodiment of the invention is shown, which will be explained in more detail below.
