Description

Glühkopfmotor. Die Erfindung betrifft einen Ölmotor mit im Kompressionsraum angeordnetem Brennstoffvorwärmeelement und bezweckt, durch geeignete Anordnung desselben eine Durchwirbelung der Verbrennungsluft und .damit eine gute Mischung mit dem Brennstoff ztt bewirken. Bei den bisher bekannten Vorwärmevorrichtungen war das -\"orwärmeelement derart im Kompressionsraum angeordnet, daß zwar die `"orwärmung des Brennstoffes, jedoch keine die Brennstoffluftmischung begünstigende Wirkung erzielt werden konnte.Glow head motor. The invention relates to an oil motor with in the compression space arranged fuel preheating element and the purpose of the same by suitable arrangement a swirling of the combustion air and thus a good mixture with the fuel cause ztt. In the case of the previously known preheating devices, this was the - \ "preheating element arranged in the compression chamber in such a way that the `` "heating of the fuel, however, no effect favoring the fuel-air mixture could be achieved.

Um dies zu ermöglichen, wird erfindungsgemäß das Vorwärmeeletnent derart angeordnet und gestaltet, daß die vom Kolben in den Kompressionsraum gepreßte Luft an dem Element vorbeistreichen muß und dabei kräftig durchwirbelt wird.In order to make this possible, the preheating element is used according to the invention arranged and designed in such a way that the piston pressed into the compression chamber Air must sweep past the element and is swirled vigorously.

In- der Zeichnung sind zwei Ausführungsbeispiele der Erfindung dargestellt; es zeigt Abb. i den Zylinderkopf eines mit dem Vorwärmeelement versehenen Glühkopfmotors im Längsschnitt, Abb.2 die Draufsicht auf diesen Zylinderkopf bei angenommener Glühhaube und Abb. 3 und .4 eine andere Ausführungsform des Erfindungsgegenstandes in den gleichen Darstellungen wie Abb. i und 2.In the drawing, two exemplary embodiments of the invention are shown; Fig. i shows the cylinder head of a hot-head engine provided with the preheating element in longitudinal section, Fig. 2 shows the top view of this cylinder head with an assumed glow hood and FIGS. 3 and 4 show another embodiment of the subject matter of the invention in FIGS same representations as fig. i and 2.

Das durch ein Druckrohr a und die Bohrung h eines durch den Zylinderdeckel geführten Stehbolzens gespeiste Vorwärmeelement c ist als Rohrschlange ausgebildet und hinter dem Hals des Glühkopfes angeordnet. Es mündet in eine Düse d mit einer feinen Einspritzöffnung f. Diese Anordnung des Vorwärmeelementes hinter dem Hals des Glühkopfes begünstigt die :Mischung von Luft und Brennstoff außerordentlich, da der vom Kolben g bei der Kompression durch den Hals getriebene Luftstrom von den Rohrwindungen destElementes zerteilt und durchwirbelt wird. Durch geeignete Versetzung .der Rohrwindungen gegeneinander und durch zweckmäßige Gestaltung ihres Profils kann die Durchwirbelung noch begünstigt werden. Bei dem Ausführungsbeispiel nach Abb. i und 2 sind die Rohrwindungen zu diesem Zweck exzentrisch zueinander angeordnet. Bei der Ausführungsform nach Abb.3 und 4. ist hierfür eine pyratnidenartige lvlbereinanderlagerung der Rohrwindungen vorgesehen, wobei zur Erhöhung der Wirbelwirkung der Rohrquerschnitt in Form eines schräg nach innengerichteten flachen Ovales gestaltet ist.That through a pressure pipe a and the hole h one through the cylinder cover guided studs fed preheating element c is designed as a pipe coil and arranged behind the neck of the incandescent lamp. It opens into a nozzle d with a fine injection opening f. This arrangement of the preheating element behind the neck of the glow head favors the: Mixture of air and fuel extraordinarily, since the air flow driven by the piston g during compression through the neck of the pipe windings of the element is divided and whirled through. Through suitable Displacement of the pipe windings against each other and through appropriate design of their The turbulence can still be favored by the profile. In the embodiment According to Fig. i and 2, the pipe windings are eccentric to each other for this purpose arranged. In the embodiment according to Figures 3 and 4, this is a pyramid-like one lvlüberlagerung the pipe windings provided, in order to increase the vortex effect the pipe cross-section is designed in the form of an obliquely inwardly directed flat oval is.
