Description

Selbst- oder fremdzündende luftverdichtende Viertaktbrennkraftmaschine mit im Zylinderkopf liegenden Ventilen nach Patent 674 526 Die Unterbringung des Brennstoffzwischenbehälters mit den von ihm ausgehenden Bohrungen zum Drosselkanal zwischen Hubraum und Kammer, des Drosselkanals selbst und des das Brennstoffzuführungsventil enthaltenden Zwischenstücks nach Patent 674 526 macht bei einer Viertaktbrennkraftmaschine, bei welcher Ein- und Auslaßventil im Zylinderdeckel sitzen, Schwierigkeiten.Self-igniting or externally igniting air-compressing four-stroke internal combustion engine with valves located in the cylinder head according to patent 674 526 . with which inlet and outlet valve sit in the cylinder cover, difficulties.

Nach der vorliegenden Erfindung wird ein Einsatzstück seitlich im Zylinderkopf mit seiner Achse parallel zur Zylinderachse angeordnet, welches den Verbindungskanal zwischen der schräg zur Zylinderachse liegenden Kammer und dem Zylinderbrennraum sowie die Umführungsleitung für diesen Kanal und die in die Umführungsleitung einmündende Brennstoffzuführungseinrichtung enthält, wobei dasselbe, um eine besonders bei leichten Brennstoffen unerwünschte. Erwärmung zu. verhüten, einerseits mit möglichst kleiner Fläche an den Zylinderraum und an den Verbindungskanal grenzt, um nur wenig Wärme aufnehmen zu können, und andererseits auf langer Strecke mit entsprechend großer Oberfläche durch den wassergekühlten Zylinderdeckel geführt wird, um hier weitgehend gekühlt zu werden.According to the present invention, an insert is laterally in the Cylinder head arranged with its axis parallel to the cylinder axis, which the Connection channel between the oblique to the cylinder axis and the chamber Cylinder combustion chamber as well as the bypass line for this channel and the one in the bypass line Containing emptying fuel supply device, the same to a special undesirable for light fuels. Warming too. prevent, on the one hand with as much as possible small area adjoins the cylinder space and the connecting channel by only a little To be able to absorb heat, and on the other hand with correspondingly over long distances large surface is passed through the water-cooled cylinder cover to here to be largely cooled.

Die Abbildung zeigf als Ausführungsbeispiel einen Zylinderkopf mit Einsatzstück und Kammer im Schnitt.The figure shows a cylinder head as an exemplary embodiment Insert and chamber in section.

In den Zylinderkopf q ist das Zwischenstück z parallel zur Achse des Zylinders a eingesetzt, das den Zwischenbehälter g mit den Bohrungen d und f enthält, welche zu dem das Zwischenstück z schräg durchbohrenden Drosselkanal c führen. Dieser verbindet über eine gleichachsig mit ihm im Zylinderdeckel q angebrachte Bohrung den Hubraum im Zylinder a mit der in gleicher Richtung schräg zur Seite des Zylinderdeckels q in demselben angeordneten Kammer b. In diese ist mit geringem Abstand zur Kammerwand ein Futter e aus hitzebeständigem Material eingesetzt, das durch die Verschraubung r gehalten wird, welche gleichzeitig die Glühkerze s aufnimmt.In the cylinder head q, the intermediate piece z is parallel to the axis of the Cylinder a inserted, which contains the intermediate container g with the bores d and f, which lead to the throttle channel c piercing through the intermediate piece z at an angle. This connects via a bore coaxial with it in the cylinder cover q the displacement in cylinder a with the inclined in the same direction to the side of the cylinder cover q in the same arranged chamber b. This is at a small distance from the chamber wall a lining made of heat-resistant Material used that by the screw connection r is held, which at the same time receives the glow plug s.

Die Zufuhr des Brennstoffes zum Zwischen-Behälter g erfolgt durch die Leitung p und" wird durch das Nadelventil k gesteuert, welches gegen den Druck der Feder j, die im Deckel k ihr Widerlager hat, durch den Doppelhebel L angehoben wird. Der Zapfen in, um welchen der Doppelhebel l schwingt, ist außermittig gelagert und dadurch in der Höhe verstellbar. Diese Höhenverstellung dient zur Reglung der Brennstoffmenge. Die Bewegung des Doppelhebels L erfolgt durch Vermittlung der Verbindungsstange t von der Nabe o des Hebels n, welcher das Saugventil der Maschine betätigt.The fuel is fed to the intermediate container g through the line p and "is controlled by the needle valve k, which is raised by the double lever L against the pressure of the spring j, which has its abutment in the cover k. The pin in, around which the double lever l swings is eccentrically mounted and thus adjustable in height. This height adjustment is used to regulate the amount of fuel. The movement of the double lever L is effected by means of the connecting rod t of the hub o of the lever n, which actuates the suction valve of the machine .

An Stelle des beschriebenen, vom Antrieb des Saugventils gesteuerten, nach außen öffnenden Nadelventils kann auch ein nach innen öffnendes Ventil mit entsprechend belasteter Ventilnadel oder auch ein selbsttätiges Rückschlagventil in das Zwischenstück N eingebaut werden.Instead of the described, controlled by the drive of the suction valve, outwardly opening needle valve can also have an inwardly opening valve appropriately loaded valve needle or an automatic check valve can be installed in the intermediate piece N.

Durch die Auskleidung der Kammer b mit dem Futter e ist man in der Lage, derselben eine Wandungswärme zu geben, die zum rechtzeitigen Ablauf des Verbrennungsvor-. ganges in ihr erforderlich ist. Der dabei aus der Kammer b durch die Drosselbohrung c schräg gegen die Zylinderachse austretende Gasstrahl erhält vorteilhaft eine solche Richtung, daß er zwischen das Ein- und Auslaßventil trifft.By lining the chamber b with the lining e one is in the Able to give the same a wall heat that is necessary for the timely completion of the combustion process. ganges in it is required. The thereby from the chamber b through the throttle bore c gas jet exiting obliquely against the cylinder axis advantageously receives such a jet Direction that it hits between the inlet and outlet valve.
