Anlaßkarburiervorrichtung. .Tempering carburizing device. .

Die Erfindung bezieht sich auf solche Verbrennungskraftmaschinen, die mittels elektrisch entzündeter, karburierter Luft artgelassen werden und nach dem Anlassen mit Zündung durch die Verdichtungswärme oder mit sonstiger, nicht elektrischer Zündung arbeiten. In solchen Maschinen ist es von großer Bedeutung, daß die karburierte Luft, unmittelbar nachdem der Kolben oder die Kurbelwelle der Maschine, jjwecks Anlassens in Bewegung gesetzt worden ist, in den Verbrennungsraum des Zylinders strömt und gleichzeitig verhindert wird, anderswohin als in den Verbrennungsraum zu treten.The invention relates to such internal combustion engines by means of electrically ignited, carburized air and after starting with ignition work with the heat of compression or with other non-electrical ignition. In In such machines it is of great importance that the carburized air, immediately after the piston or the crankshaft of the engine is set in motion for the purpose of starting has been, flows into the combustion chamber of the cylinder and prevented at the same time will go anywhere other than the combustion chamber.

Zu diesem Zwecke soll die Luft unmittelbar vor oder gerade während ihres Eintritts in den Verbrennungsraum des Zylinders karburiert werden. Hierdurch wird erreicht, daß schon während der ersten Umdrehung der Kurbelwelle im Verbrennungsraum karburierte Luft vorhanden ist.For this purpose, the air should be immediately before or just as it enters are carburized in the combustion chamber of the cylinder. This achieves that carburized in the combustion chamber during the first rotation of the crankshaft Air is present.

Der Zweck der Erfindung ist der, eine Karburiervorrichtung zu schaffen, die unmittelbar vor den Öffnungen, durch die die Spülluft in den Verbrennungsraum des Zylinders tritt, oder in unmittelbarer Verbindung mit diesem Raum angebracht werden kann, und die ohne Verwendung einer Pumpe oder überhaupt einer Antriebsvorrichtung eine im wesentlichen gleichbleibende Menge der Karburierungsflüssigkeit bei jedem Einströmen von Spülluft in den Zylinder während der Anlaßperiode liefert.The purpose of the invention is to provide a carburizing device which immediately in front of the openings through which the scavenging air enters the combustion chamber of the cylinder, or in direct connection with this room, and those without Use of a pump or even a drive device is essentially the same Amount of carburizing liquid each time purging air flows into the Cylinder supplies during the cranking period.

Diese Karburiervorrichtung besteht im wesentlichen aus einem zur Aufnahme einer für das Anlassen erforderlichen Menge einer Karburierungsflüssigkeit dienenden Behälter, 'welcher mit einem Flüssigkeitsverschluß versehen ist, der einerseits in den Luftraum des Behälters oberhalb der Flüssigkeit, anderseits in die Luftzuleitung oder den Verbrennungsraum der Maschine mündet und unten durch eine kleine Öffnung mit dem Behälter in Verbindung steht.This carburizing device consists essentially of one for receiving a for the tempering required amount of a carburizing liquid serving container, 'which is provided with a liquid seal, which on the one hand in the air space of the container above the liquid, on the other hand in the air supply line or the combustion chamber the machine opens and below through a small opening with the container in connection stands.

Eine beispielsweise Ausführungsform einer Anlaßkarburiervorrichtung gemäß dieser Erfindung ist in Fig. 1 der Zeichnung dargestellt. Fig. 2 zeigt einen Schnitt einer Verbrennungskraftmaschine mit der Anlaßkarburiervorrichtung in Seitenansicht. Fig. 3 ist ein Diagramm über die Wirkungsweise.An exemplary embodiment of a tempering carburizing apparatus according to this invention is shown in Fig. 1 of the drawing. Fig. 2 shows a section of an internal combustion engine with the tempering carburizing device in side view. Fig. 3 is a diagram of the operation.

Die Anlaßkarburiervorrichtung besteht im wesentlichen aus einem Behälter 1 mit einer Einfüllöffnung 4 für die Karburierungsflüssigkeit sowie mit einem Ausströmungskanal 5. Die Einfüllöffnung ist mit einem Schraubdeckel 3 versehen. Der Ausströmkanal 5 ist durch den Innenraum eines mit Außengewinde versehenen !Rohransatzes 2 gebildet. Der Kanal 5 steht mit dem Innern des Behälters 1 · durch zwei zu einem Flüssigkeitsverschluß ausgebildete Kanäle 6, 7 in Verbindung, die beide einen Querschnitt haben, welcher gleich groß ist wie derjenige des Kanals 5. Der untere Teil der Kanäle 6, 7 bildet zweckmäßigThe tempering carburizing device consists essentially of a container 1 with a Filling opening 4 for the carburizing liquid and with an outflow channel 5. The filling opening is provided with a screw cap 3. The outflow channel 5 is formed by the interior of a pipe socket 2 provided with an external thread. The channel 5 stands with the interior of the container 1 by two to form a liquid seal formed channels 6, 7 in connection, both of which have a cross section which is the same is as large as that of the channel 5. The lower part of the channels 6, 7 is useful

Claims

an enlarged space 8, which through a small opening 9 with the interior of the container ι is in direct contact. The cross-section of this opening is very small compared to the cross section of the channel 7.

The filling opening 4 is expediently moved slightly higher than the channel 5 and the upper edge of the channel 7 higher than the lower edge of the opening 4. This achieves on the one hand that the carburizing liquid can enter the channel 5 during filling, on the other hand that the channel 7 always opens above the liquid level in the container 1.
The Anlaßkarburiervorrichtüng is either in the wall of the overflow channel between the scavenging pump and the cylinder chamber of the internal combustion engine (directly in front of the inlet openings of this channel in the cylinder chamber) or directly in the wall of the cylinder chamber, in such a way that the channel 5 or in this overflow channel . opens directly into the cylinder chamber. According to FIG. 2, the starting carburizing device is arranged in the former manner in a two-stroke engine, the crankcase of which is designed to face the pump chamber. The carburizing device is thus connected to the overflow channel 10 between the pump chamber 11 and the cylinder chamber 12 directly in front of the inlet opening 13.

When the machine is put into operation

a carburizing liquid, e.g. B.

\ Gasoline, poured into container 1 until something

Liquid flows over into the overflow channel 10 for the purpose of carburizing the air located there, after which the cover 3 is screwed on. The liquid level is determined by the lower edge of the channel 5, as from Fig. Ι shows. The air above the liquid level in the container 1 is now completely closed by liquid. If now the piston is out of its top dead center (I, Fig. 3) is moved downwards, the air in the crankcase 11 and thus in the

Overflow channel 10 compressed. Usually an overpressure of Reached 0.2 to 0.3 kg. The liquid seal is too weak to withstand this pressure resist and an air overflow from

finally to allow through the opening 9 by this opening, as mentioned above, has a much smaller cross-section than the channel 7, so that it cannot cancel the effect of the liquid seal.

Air therefore flows from the channel 10 through the channels 5, 6 and 7 and possibly also through the opening 9 to the container 1. The liquid in the channels 5 to 7 is entrained by the air and is intimately mixed with it. During the downward stroke of the piston, first the exhaust port 14 (II, Fig. 3) and then the inlet port 13 (III, Fig. 3) is exposed by the piston. As soon as the inlet opening 13 becomes free, the scavenging air flows over from the pump chamber 11 to the cylinder chamber 12, as a result of which the pressure in the pump chamber 11 and in the overflow channel 10 is rapidly reduced. The high-carburized air above the liquid in the container, which is under overpressure, now flows back through the channel system 7, 6, 5 and entrains the liquid that has entered the room % through the opening 9. The amount of gasoline supplied to channel 10 in this way is carried along by the air still flowing through this channel and mixed with the air in the cylinder, so that an air-gas mixture is created which is ignited at the appropriate time by an electrical ignition device.

Because the carburizing device is only used for tempering, it is exclusive at low revs, so that the one produced by an earlier combustion Overpressure in the cylinder completely disappeared as a result of the exposure of the exhaust port 14 is when the inlet opening is exposed.

The opening 9 is chosen so large that it is at the time between an overflow of air from container 1 and a subsequent overflow of air to container 1 allows the amount of liquid to pass through which is necessary for ignition, even if it is large Speed of the machine,

The container 1 is chosen so large that it has a sufficient amount for tempering the carburizing liquid can absorb. When the machine is in operation, the Liquid consumed and therefore no closure of the carburator from the canal or Room 2 required.

If the carburizing device opens directly into the combustion chamber of the machine, may only be ignited if, as a result of a drop in pressure in the combustion chamber, carburizing liquid got into the combustion chamber.
