Description

Selbstzündender Ölmotor mit einem Hohlraum im Kolben Die vorliegende Erfindung bezieht sich auf einen selbstzündenden Ölmotor, insbesondere für luftlose Einspritzung, mit einem Hohlraum im Kolben, der als zusätzlicher Verbrennungsraum dient.Compression-igniting oil engine with a cavity in the piston The present The invention relates to a compression-ignition oil engine, particularly for airless ones Injection, with a cavity in the piston that acts as an additional combustion chamber serves.

Es sind Motoren dieser Art bekannt, bei denen Luft und Brennstoff räumlich getrennt voneinander in den Kolbenhohlraum eingeführt werden, so daß sie sich erst dort mischen können. Die Folgen dieser späten und demzufolge ungenügenden Vermischung sind schwierige Zündung und unvollständige Verbrennung.There are known engines of this type in which air and fuel spatially separated from each other are introduced into the piston cavity, so that they can only mix there. The consequences of this late and consequently insufficient Mixing is difficult ignition and incomplete combustion.

Ferner ist auch schon vorgeschlagen worden, auf den Kolbenboden einen halbkugelförmigen hohlen Aufsatz aufzusetzen und dessen Inneres finit dem Zylinderraum durch ein im Scheitel der Halbkugel angebrachtes Mundstück zu verbinden. Wenn der Kolben in seiner inneren Totlage ankommt, steht das Mundstück dem Einspritzkanal ummittelbar gegenüber. In diesem Augenblick schiebt der Betriebsbrennstoff ein ihm vorgelagertes, nicht oder nur schwer zündbares Sperrmittel aus der Einspritzkanalmündung heraus und durch das Mundstück in den hohlen Aufsatz hinein. Das Sperrmittel soll nun, zusammen mit der im Aufsatz eingeschlossenen verdichteten Luft, beim Herausströmen aus dem Aufsatz den hinter dem Sperrmittel folgenden Betriebsbrennstoff zerstäuben. Der Zeitpunkt, in dem der Betriebsbrennstoff in den Zylinder eintritt, ist aber dabei so gewählt, duß ihm keine Möglichkeit geboten ist, in den hohlen Aufsatz hineinzugelangen.Furthermore, it has also already been proposed to put one on the piston crown to put on hemispherical hollow attachment and its interior finite the cylinder space to be connected by a mouthpiece attached to the apex of the hemisphere. If the When the piston arrives in its dead center position, the mouthpiece is in front of the injection port directly opposite. At that moment the plant fuel is sliding in him upstream, non-ignitable or difficult to ignite locking means from the injection port opening out and through the mouthpiece into the hollow attachment. The locking means should now, together with the compressed air enclosed in the attachment, when flowing out Atomize the operating fuel that follows the locking agent from the attachment. However, the point in time at which the operating fuel enters the cylinder is chosen in such a way that there is no possibility of getting into the hollow attachment.

Von diesen bekannten Motoren unterscheidet sich der vorliegende in verschiedener Hinsicht. Gemäß der Erfindung ist nämlich der zusätzliche Verbrennungsraum mit dem übrigen Verbrennungsraum durch einen Drosselquerschnitt verbunden, und die Gestalt des übrigen Verbrennungsraumes sowie die Lage der Brennstoffdüse sind so gewählt, daß die beim Verdichtungshub entstehende Luftströmung Brennstoff nach dem Drosselquerschnitt hintreibt und daß Brennstoff und Luft zusammen durch den Drosselquerschnitt hindurch in den Kolbenhohlraum hineinströmen. Auf diese Weise wird eine besonders innige Vermischung von Luft und Brennstoff erreicht, die das Selbstzünden der Zylinderladung und die Verbrennung begünstigt. Es ist vorteilhaft, die Drosselstelle zwischen dem zusätzlichen und dem übrigen Verbrennungsraum nur kurz zu machen. Bringt man vor der Drosselstelle noch eine trichterförmige Einsenkung im Kolben an, so verlängert man dadurch den Mischweg und befördert erfahrungsgemäß Zündung und . Verbrennung noch bedeutend.The present one differs from these known engines in different ways. According to the invention is namely the additional combustion chamber connected to the rest of the combustion chamber by a throttle cross-section, and the The shape of the rest of the combustion chamber and the position of the fuel nozzle are the same chosen that the resulting air flow during the compression stroke fuel after Throttle cross section and that fuel and air together through the throttle cross section flow through into the piston cavity. That way one becomes special Intimate mixing of air and fuel is achieved, which causes the cylinder charge to self-ignite and favors combustion. It is advantageous to place the throttle point between the to make additional and the rest of the combustion chamber only briefly. One brings up the throttle point has a funnel-shaped indentation in the piston, so extended you thereby the mixing path and experience has shown that ignition and. combustion still significant.

Auf der Zeichnung sind als Anwendungsbeispiele der Erfindung zwei verschiedene Ausführungen von Zylindern für Ölmotoren mit luftlcser Einspritzung im Längss-hnitt dargestellt.The drawing shows two examples of application of the invention various designs of cylinders for oil engines with air-soluble injection shown in longitudinal section.

In beiden Fällen ist der Zylinder mit Z, der Kolben mit d, der im Kolben untergebrachte zusätzliche Verbrennungsraum mit b und die im Zylinderboden angeordnete Brennstoffeinspritzdüse mit e bezeichnet. Der zusätzliche Verbrennungsraum im Kolben ist mit dem übrigen Verbrennungsraum d durch einen Drosselquerschnitt.c verbunden.In both cases the cylinder with Z, The piston with d, the additional combustion chamber housed in the piston with b and the im Fuel injection nozzle arranged in the cylinder base is denoted by e. The additional The combustion chamber in the piston is connected to the rest of the combustion chamber d by a throttle cross-section c tied together.

Beide Beispiele zeigen Viertaktrnascbinen. Das Lufteinlaßventil ist jeweils mit 1- und das Auspuffv entil mit ä bezeichnet: Die Wirkungsweise , der Maschine nach Abb, z ist, soweit sie in diesem Zusamwenhang wichtig ist, folgende: Die beim Saughub in den Zylinder gesaugte Luft wird beim nächsten Hub verdichtet. Dabei entsteht eine lebhafte Luftstiörriung durch den Drosselquerschnitt c hindurch in den Kolbehhohlraum b hinein. Der etwa gegen Ende des Verdichtungshubes aus der Düse e tretende Brennstoff gelangt mindestens zum Teil schon im Raum d - also vor dem Drosselquerschnitt c - mit der in den Kolbenhohlraum strömenden, infolge der Verdichtung erhitzten Luft in Berührung, mischt sich mit dieser und wird von der Luftströmung nach dem Drosselquerschnitt hingetrieben. Die Achse der Brennstoffdüse e fällt mit derjenigen der eingeschnürten Drosselstelle zusammen, so daß mindestens ein Teil des Brennstoffes in den Kern der Luftströmung hineingespritzt wird. Das Brennstoffluftgemisch tritt dann durch den Drosselquerschnitt c, wird dabei wie in einer Düse noch inniger gemischt und entzündet sich. Die einmal eingeleitete Verbrennung wird überallhin weitergetragen, wo sich brennbares Gemisch gebildet hat.Both examples show four-stroke engines. The air inlet valve is each with 1- and the exhaust valve with ä: The mode of operation, the The machine according to Fig, z, insofar as it is important in this context, is the following: The air drawn into the cylinder on the suction stroke is compressed on the next stroke. This creates a lively air disturbance through the throttle cross-section c into the piston cavity b. The approximately towards the end of the compression stroke from the Fuel coming out of nozzle e is at least partially already in space d - i.e. before the throttle cross-section c - with the flowing into the piston cavity, as a result of the When heated air comes into contact with compression, it mixes with this and is released by the Air flow driven towards the throttle cross-section. The axis of the fuel nozzle e coincides with that of the constricted throttle point, so that at least some of the fuel is injected into the core of the air flow. That The fuel-air mixture then passes through the throttle cross-section c, is how mixed even more intimately in a nozzle and ignites. The once initiated Combustion is carried on wherever a combustible mixture is formed Has.

Beim zweiten Ausführungsbeispiel ist die Wirkungsweise grundsätzlich ebenso wie beim ersten. Vor dem Drosselquerschnitt ist aber noch eine trichterförmige Einsenkung b1 angeordnet. Diese Einsenkung ist natürlich nicht an eine im Längsschnitt rein kegelförmige und im Querschnitt runde Form gebunden.In the second embodiment, the mode of operation is fundamental just like the first. In front of the throttle cross-section, however, there is still a funnel-shaped one Depression b1 arranged. This depression is of course not similar to a longitudinal section purely conical and bound in cross-section round shape.

Die Gestalt des zusätzlichen Verbrennungsraumes im Kolben ist natürlich auch nicht an die auf der Zeichnung angegebene, vielfach besonders vorteilhafte Birnenform gebunden. An Stelle eines einzigen zusätzlichen Verbrennungsraiunes können auch, ohne vom Erfindungsgedanken abzuweichen, mehrere Verbrennungsräume im Kolben vorgesehen sein, wenn dies notwendig oder vorteilhaft erscheint.The shape of the additional combustion chamber in the piston is natural not even the one indicated on the drawing, which is often particularly advantageous Tied pear shape. Instead of a single additional combustion chamber, you can also, without deviating from the inventive concept, several combustion chambers in the piston be provided if this appears necessary or advantageous.

Die Erfindung läßt sich mit Vorteil anwenden bei Ölmotoren jeder Art, wie reinen Selbstzündmotoren, Motoren, die zum Anlassen eine Einrichtung zum Unterstützen der Zündung brauchen, sowie Glühkopfmotoren. Die Erfindung ist auch anwendbar bei Maschinen, bei denen der Brennstoff mit Luft eingeblasen wird. Ebenso erstreckt sie sich nicht nur auf Viertakt-, sondern auch auf Zweitaktmotoren.The invention can be used with advantage in oil engines of any type, like pure compression-ignition engines, engines that have a device to assist in starting the ignition, as well as hot-bulb engines. The invention is also applicable to Machines in which the fuel is blown with air. Likewise extends not only on four-stroke, but also on two-stroke engines.
