Description
Brennkraftmaschine mit abnehmbarem Zylinderkopf Die Erfindung betrifft eine Brennkraftmaschine mit abnehmbarem Zylinderkopf und einer durch die Trennfläche zwischen Zylinderblock und Zylinderkopf hindurchgeführten Verbindung für das Kühlwasser.
Es kann für eine im Dauerbetrieb arbeitende Brennkraftmaschine speziell in räumlich beengter Aufstellung, beispielsweise auf Schiffen, von Wichtig keit sein, das Abnehmen und Wiederaufsetzen eines Zylinderkopfes im Reparaturfalle in der kürzest mög lichen Zeit zu bewerkstelligen, um einen längeren Stillstand der Maschine zu vermeiden.
Anderseits kann beispielsweise der Zylinderkopf eines Dieselmotors druckgesteuerte Anlass- oder Manövrierventile mit Steuerleitungen und Anlassluft- anschluss, ferner kann jeder Zylinderkopf Kühlwasser- Ein- und -Austritte, Druckschmierungsanschlüsse so wie Sperrluft-Zu- und -Abführungen für die Ventile, insgesamt also eine Vielzahl von Leitungsanschlüssen für solche Betriebsmittel besitzen, welche speziell im Zylinderkopf funktionell benötigt werden.
Das Einbeziehen aller dieser Anschlüsse in die Zylinderkopfmontage würde dieselbe aussergewöhn lich erschweren und verzögern.
Zur Erleichterung und Beschleunigung von De montage und Montage des Zylinderkopfes wird er findungsgemäss ausser der Verbindung für das Kühl wasser mindestens eine Leitung für ein weiteres Be triebsmittel, welches zur Verwendung am Zylinder kopf bestimmt ist, am Zylinderblock angeschlossen und durch die Trennfläche zwischen Block und Kopf hindurchgeführt.
Dadurch wird der Vorteil erzielt, dass beim Ab nehmen und Wiederaufsetzen des Zylinderkopfes nur noch die Brennstoffdruckleitung und im Falle eines Kopfes mit Gasventilen noch die Abgasleitungen zu lösen und wieder zu befestigen sind, so dass die notwendige Arbeitszeit um ein vielfaches der bis herigen reduziert werden kann.
Bei einer Ausführung der Erfindung kann die konstruktive Massnahme getroffen sein, dass ein An satzstück am Zylinderblock angeordnet ist, welches zur Aufnahme der Leitungen für die Betriebsmittel dient.
Die Erfindung kann aber auch in zweckmässiger Weise durch ein Zwischenstück am Zylinderblock verwirklicht werden, welches zwischen dem Zylinder block und dem Zylinderkopf angeordnet ist, den Laufbüchseneinsatz aufnimmt und gleichzeitig zur Aufnahme der Leitungen für die Betriebsmittel dient.
Das sich beim Hindurchführen durch die Trenn fläche ergebende Dichtungsproblem kann zweck mässig so gelöst sein, dass in an sich bekannter Weise den Spalt in der Trennfläche zwischen Block und Kopf überbrückende, je an eine Leitung für Betriebs mittel angeschlossene Rohrabschnitte vorgesehen sind, welche sowohl mit dem Block als auch mit dem Kopf dichtend verbunden sind.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt.
Die Fig. 1 und 2 zeigen je einen Schnitt durch einen Zylinder der Brennkraftmaschine nach der Er findung.
In Fig. 1 bezeichnet 1 ein Zylindergussstück mit dem Einsatz 2, welche zusammen den Zylinderblock bilden, in welchen die Zylinderlaufbüchse 3 ein gesetzt ist. Am Einsatz 2 sind die Kühlwasser anschlüsse 4, 5 angeordnet.
Das durch den Stutzen 4 eintretende Kühlwasser wird mit Hilfe des Verbin dungsstückes 6 durch die Trennebene A -B vom Zylinderblock 1 in den Zylinderkopf 7 geleitet, wo es die Kühlmittelräume 8, 8' durchströmt, um dem Austrittsstutzen 5 durch den im Zylinderkopf 7 be- findlichen Kanal 8" zugeleitet zu werden, wobei es wiederum ein die Trennebene A-B durchquerendes Verbindungsstück 9 durchläuft. Ein Teilstrom des für den Zylinderkopf 7 bestimmten Kühlmittels wird aus demselben abgezweigt und tritt durch das Verbin dungsstück 10 in den Zylinderblock 1 ein.
Ferner besitzt der Einsatz 2 den Schmieröl anschluss 11, durch welchen Drucköl zum Schmieren der Ventile 12 in den Zylinderkopf 7 zu Schmier stellen 13 gelangt, wobei die Ölleitung durch das Zwischenstück 14 durch die Trennebene A-B hin durchgeführt ist.
Fig. 2 zeigt eine ähnliche Ausführung der Erfin dung, wobei im Unterschied zur Ausführung nach Fig. 1 die Anschlüsse 15, 16, 17 an dem Ansatz stück 18 des Zylinderblockes 1 angeordnet sind. In dem gezeigten Beispiel handelt es sich bei den An schlüssen 15, 16 um Druckluftsteuerleitungen für das Anlassventil 19 sowie beim Anschluss 17 um die An lassluftleitung. Ferner sind nicht dargestellte Kühl- wasseranschlüsse vorgesehen.
Internal combustion engine with a removable cylinder head The invention relates to an internal combustion engine with a removable cylinder head and a connection for the cooling water which is passed through the interface between the cylinder block and the cylinder head.
For an internal combustion engine operating continuously, especially in a confined space, for example on ships, it can be important to remove and replace a cylinder head in the shortest possible time in order to avoid a prolonged downtime of the machine.
On the other hand, the cylinder head of a diesel engine, for example, can have pressure-controlled starting or maneuvering valves with control lines and starting air connections; furthermore, each cylinder head can have cooling water inlets and outlets, pressure lubrication connections and sealing air inlets and outlets for the valves, i.e. a large number of Have line connections for such equipment, which are functionally required specifically in the cylinder head.
The inclusion of all these connections in the cylinder head assembly would make the same exceptionally difficult and delayed.
To facilitate and accelerate the de-assembly and assembly of the cylinder head, according to the invention, in addition to the connection for the cooling water, at least one line for another operating means, which is intended for use on the cylinder head, is connected to the cylinder block and through the interface between the block and head passed through.
This has the advantage that when removing and replacing the cylinder head, only the fuel pressure line and, in the case of a head with gas valves, the exhaust lines have to be loosened and reattached, so that the necessary working time can be reduced many times that of the previous one .
In one embodiment of the invention, the structural measure can be taken that an attachment piece is arranged on the cylinder block, which serves to accommodate the lines for the operating means.
The invention can also be implemented in an expedient manner by an intermediate piece on the cylinder block, which is arranged between the cylinder block and the cylinder head, receives the liner insert and at the same time serves to accommodate the lines for the resources.
The sealing problem that arises when passing through the separating surface can be expediently solved in such a way that, in a known manner, the gap in the separating surface between the block and the head is provided which are each connected to a line for operating means and which are connected to both the Block as well as with the head are sealingly connected.
An exemplary embodiment of the invention is shown schematically in the drawing.
1 and 2 each show a section through a cylinder of the internal combustion engine according to the invention.
In Fig. 1, 1 denotes a cylinder casting with the insert 2, which together form the cylinder block in which the cylinder liner 3 is set. On the insert 2, the cooling water connections 4, 5 are arranged.
The cooling water entering through the nozzle 4 is passed with the help of the connector 6 through the parting plane A -B from the cylinder block 1 into the cylinder head 7, where it flows through the coolant spaces 8, 8 'to the outlet nozzle 5 through the load in the cylinder head 7 Sensitive channel 8 ″, which in turn passes through a connecting piece 9 crossing the parting line AB. A partial flow of the coolant intended for the cylinder head 7 is branched off from the same and enters the cylinder block 1 through the connecting piece 10.
Furthermore, the insert 2 has the lubricating oil connection 11, through which pressure oil for lubricating the valves 12 in the cylinder head 7 reaches lubricating points 13, the oil line being passed through the intermediate piece 14 through the parting plane A-B.
Fig. 2 shows a similar embodiment of the inven tion, in contrast to the embodiment of FIG. 1, the connections 15, 16, 17 on the extension piece 18 of the cylinder block 1 are arranged. In the example shown, connections 15, 16 are compressed air control lines for starting valve 19 and connection 17 is the starting air line. Furthermore, cooling water connections (not shown) are provided.
