Description

Schmierung für gasbetriebene Brennkraftmaschinen Bei Zweitaktmotoren mit Kurbelkammerspülung erfolgt die Schmierung im allgemeinen dadurch, daß man dem als Kraftstoff benutzten Benzin o. dgl. Beine, bestimmte Menge Schmieröl zusetzt, das dann in Form einer Benzin-Öl-Mischung über die Brennstoffleitung, Vergaser usw. in den Motor gelangt.Lubrication for gas-powered internal combustion engines for two-stroke engines with crank chamber scavenging, the lubrication is generally done by the petrol or similar legs used as fuel, adding a certain amount of lubricating oil, which is then in the form of a gasoline-oil mixture via the fuel line, carburetor, etc. gets into the engine.

Bei Verwendung von gasförmigen Kraftstoffen, wie z. B. Treib- oder Flüssiggas, Generatorgas usw., bereitet aber die Schmierung der genannten Zweitaktmotoren Schwierigkeiten, da es nicht möglich ist, dem Treibstoffgas 'öl beizumengen. Es ist in diesem Falle daher gewöhnlich notwendig, eine besondere Ölpumpe zur Zufuhr des Schmieröls vorzusehen.When using gaseous fuels, such as. B. driving or Liquid gas, generator gas, etc., but prepares the lubrication of the two-stroke engines mentioned Difficulties as it is not possible to add oil to the fuel gas. It is therefore usually necessary in this case, a special oil pump for the supply of the lubricating oil.

Da dieser Weg aber verhältnismäßig teuer und umständlich ist, hat man die Ölung auch. schon dadurch vorgenommen, daß man im Ölvorrats:behälter, ähnlich Tide bei dem flüssigen Kraftstoff, einen Schwimmer verwendet und die entsprechenden Ölmengen von dort über eine Leitung durch den Unterdruck des Motors absaugt. Die öläbflußleitung vom Schwimmer wird an den Motor oder Vergaser bzw. Gasmischer zugeführt und entweder vor dem Vergaser oder an die Saugleitung zwischen Vergaser und Motor angeschlossen.Since this way is relatively expensive and cumbersome, has one the unction too. already made by the fact that in the oil supply: container, similar Tide in the case of liquid fuel, a float used and the appropriate Sucked oil quantities from there via a line through the negative pressure of the engine. the The oil outflow line from the float is fed to the engine or carburetor or gas mixer and either in front of the carburetor or on the suction line between the carburetor and the engine connected.

Diese Art der Schmierung hat aber den Nachteil, daß der Motor, wenn die Ölleitung vor dem Vergaser angebracht ist, bei geschlossener Drosselklappe, also beispielsweise bei Leerlauf oder Bergabfahrt, kein Öl erhält. Wird aber die Ölleitung zwischen Vergaser und Motor, also unmittelbar an die Saugleitung, gelegt, dann bekommt der Motor bei geschlissener Drosselklappe zuviel Öl, da ja der öleintrittsquerschnitt in die Saugleitung so bemessen sein muß, daß bei Vollgas, also bei geöffneter Drosselklappe, d. h. bei geringstem Unterdruck, in der Saugleitung genügend Öl zugeführt wird.This type of lubrication has the disadvantage that the engine, if the oil line is installed in front of the carburettor with the throttle valve closed, So, for example, when idling or driving downhill, no oil is received. But it will Oil line laid between carburettor and engine, i.e. directly on the suction line, then the engine receives too much oil when the throttle valve is closed, because of the oil inlet cross-section in the suction line must be dimensioned so that at full throttle, i.e. with the throttle valve open, d. H. at the lowest possible negative pressure, sufficient oil is fed into the suction line.

Die Erfindung besteht nun darin, daß die Ölabflußleitung vom Schwimmer unterteilt wird und je eine Ölzuleitung vor und hinter der Drosselklappe in die Saugleitung münden. Zweckmäßig sind die beiden Ölzuleitungen in der Weise an die Saugleitung angeschlossen, daß die eine Ölleitung an der Stelle in die Saugleitung mündet, wo im allgemeinen die Leerlaufdüse sitzt, also dicht hinter der Drosselklappe, während die andere Ölzuleitung zweckmäßig beim Lufttrichter in die Saugleitung mündet, wo die größte Luftgeschwindigkeit herrscht.The invention consists in that the oil drain line from the float is divided and one oil supply line in front of and behind the throttle valve in the Open the suction line. The two oil supply lines are useful in connected to the suction line in such a way that one oil line is at the point opens into the suction line, where the idle nozzle is generally located, i.e. tight behind the throttle valve, while the other oil supply line is useful at the air funnel opens into the suction line, where the greatest air velocity prevails.

Wenn also die Drosselklappe geschlossen ist, arbeitet nur die ersterwähnte ölzufuhrleitung, während bei geöffneter Drosselklappe, in welchem Falle hohe Luftgeschwindigkeit im Lufttrichter herrscht, öl an der letzterwähnten Zufuhrleitung mitgerissen wird.So when the throttle is closed, only the first one works oil supply line, while with the throttle valve open, in which case high air velocity prevails in the air funnel, oil is entrained at the last-mentioned supply line.

Der Querschnitt der hinter der Drosselklappe in das Saugrohr mündenden ölzufuhrleitung kann im allgemeinen kleiner sein als der Querschnitt der anderen ölzufuhrleitung, da der Bedarf an öl bei geschlossener Drosselklappe geringer ist.The cross section that opens into the intake manifold behind the throttle valve oil supply line can generally be smaller than the cross section of the others oil supply line, as the need for oil is lower when the throttle valve is closed.

In die beiden Ölzuleitungen können noch Düsen oder andere Regeleinrichtungen eingesetzt sein, um die clmenge entsprechend zu dosieren.Nozzles or other control devices can also be installed in the two oil supply lines be used to dose the amount of cl accordingly.

Während der Betrieb gewöhnlicher Zweitaktmotoren beispielsweise mit Treibgas bisher keine zuverlässige Schmierung ergibt, ist diese Aufgabe durch vorliegende Erfindung gelöst worden.During the operation of ordinary two-stroke engines, for example, with Propellant gas has so far not resulted in reliable lubrication, this task is due to the present Invention has been solved.

Auf der Zeichnung ist eine Anordnung gemäß der Erfindung in einem Ausführungsbeispiel schematisch dargestellt.In the drawing, an arrangement according to the invention is in one Embodiment shown schematically.

Die von dem das Schmieröl aufnehmenden Schmierbehälter kommende Leitung i ist in zwei Leitungen 2 und 3 unterteilt. Die Leitung 2 ist dicht hinter der Drosselklappe 6, wo im allgemeinen die Leerlaufdüse sitzt, an die Saugleitung 5 angeschlossen, während die andere Leitung 3 vor der Drosselklappe 5, zweckmäßig beim Lufttrichter 4., in die Satib leitung mündet. 7 ist die Eintrittsöffnung für das Treibgas, Hauptdüse o. dgl. Die beiden Ölzuführungen 2 und 3 müssen in ihren Querschnitten gegeneinander abgestimmt sein. Sie können verschiedenen Eintrittsquerschnitt haben, und zwar die Düse 2 kleineren Querschnitt als die Düse 3. Ferner können in beiden Ölzuleitungen noch Düsen o. dgl. zur Regelung der Ölmengen eingesetzt sein.The line coming from the lubricating oil reservoir that holds the lubricating oil i is divided into two lines 2 and 3. The line 2 is close behind the throttle valve 6, where the idle nozzle is generally located, connected to the suction line 5, while the other line 3 in front of the throttle valve 5, expediently at the air funnel 4., into which Satib leads. 7 is the inlet opening for the propellant gas, main nozzle o. The like. The two oil feeds 2 and 3 must in their cross-sections against each other be coordinated. They can have different inlet cross-sections, namely the Nozzle 2 has a smaller cross-section than nozzle 3. Furthermore, oil feed lines can be used in both nozzles or the like can be used to regulate the amount of oil.
