Abstract

The subject of the invention is a method for the preheating of liquid fuels for water-cooled internal combustion engines. The object of the invention proceeds on the assumption that a liquid fuel for internal combustion engines is correspondingly heated before passing into the carburettor or the injection pump, and thus is no longer atomised in the mixing duct of the carburettor but fed to the combustion chamber already in the carburetted state. In this, the preheater is incorporated into any line of the radiator system carrying warm water. The fuel line is in turn led through this preheater and on the way to the carburettor or to the injection pump absorbs the quantity of heat which is needed to maintain the required operating temperature of the engine. This fuel thus preheated is thereby fed into the float chamber of the carburettor or into the vacuum vessel of the injection pump.

Description

Nach dem heutigen Stand der Technik wird Verbrennungsmotoren Treibstoff in flüssiger Form zugeführt. Der flüssige Treibstoff gelangt zunächst bei Otto-Motoren in den Vergaser, bei Dieselmotoren in ein Unterdruckgefäß, von dort aus in die Einspritzpumpe. In beiden Fällen wird durch diese beiden Aggregate das sogenannte Gas-Luft-Gemisch erzeugt, das für den Betrieb von Verbrennungsmotoren erforderlich ist. Strenggenommen aber wird durch diese beiden Aggregate der Kraftstoff nicht vergast, sondern nur zerstäubt, also ein Gemischnebel erzeugt, in dem der flüssige Kraftstoff in Form von kleinen Tröpfchen durch einen Luftstrom verteilt wird. Durch Wärmeaufnahme auf dem Weg zum Zylinder werden diese kleinen Flüssigkeitsteilchen im überwiegenden Maße verdampft aber nicht optimal vergast. Dieser Vorgang ist bekannt, also Stand der Technik.According to the current state of technology, internal combustion engines Fuel supplied in liquid form. The liquid fuel first reaches Otto engines in the carburetor, in the case of diesel engines in a vacuum vessel, from there to the injection pump. In both cases, these two aggregates will so-called gas-air mixture that is generated for operation of internal combustion engines is required. Strictly speaking, however, is the two Fuel not gasified, but only atomized, a mixture of mist is generated, in which the liquid fuel in Form of small droplets distributed by an air stream becomes. By absorbing heat on the way to the cylinder, these become small liquid particles evaporated to a large extent but not optimally gassed. This process is known, that is, prior art.

Die Erfindung, "Verfahren zur Veränderung des Aggregatzustandes flüssiger Treibstoffe", verbessert das vorher beschriebene Verfahren insofern, daß dem Vergaser, bzw. der Einspritzpumpe, bereits ein unterhalb der Siedetemperatur erwärmter Treibstoff zugeführt wird.The invention, "Process for changing the state of matter liquid fuels ", improves the previously described Method in that the carburetor or the injection pump, already a fuel heated below the boiling point is fed.

Erfindungsgemäß wird das neue Verfahren in der Zeichnung dargestellt und nachstehend erläutert.According to the new method in the Drawing shown and explained below.

Wie aus der Schemazeichnung Bild I ersichtlich, wird der flüssige Treibstoff von der Treibstoffpumpe Pos. 3 aus dem Treibstofftank Pos. 1 durch die Teibstoffleitung Pos. 2 angesaugt. (Soweit die Ansaugseite betreffend) Der auf der Druckseite der Treibstoffpumpe Pos. 3 austretende Treibstoff wird auf dem Weg von der Treibstoff­ pumpe Pos. 3 zum Schwimmerbehälter Pos. 6 durch einen eigens zur Vorerwärmung des Treibstoffes entwickelten Durchlauferhitzer geführt (Pos. 5), und auf dem Weg durch diesen Durchlauferhitzer Pos. 5 erwärmt. Durch die Aufnahme dieser Wärme verändert sich der Aggregatzustand des Treibstoffes, und der Treibstoff verläßt das Mischrohr im Vergaser Pos. 7 im vorvergasten Zustand. Die Tröpfchenbildung ist damit ausgeschlossen, so daß ein optimales Gas-Luft-Gemisch in dem Zylinder zur Verbrennung gelangt. Es wird also Treibstoff gespart, der Wirkungsgrad des Motors erheblich verbessert, und zum Wohle der Menschheit wird weniger Schadstoff ausgepufft.As can be seen from the schematic drawing in Figure I, the liquid fuel is drawn in by the fuel pump, item 3, from the fuel tank, item 1, through the fuel line, item 2 . (As far as the intake side is concerned) The fuel escaping on the pressure side of the fuel pump, item 3 , is passed on the way from the fuel pump, item 3, to the float tank, item 6, through a water heater specially developed for preheating the fuel (item, 5 ), and heated on the way through this water heater pos. 5 . By absorbing this heat, the physical state of the fuel changes, and the fuel leaves the mixing tube in the carburetor, item 7, in the pre-gasified state. The formation of droplets is thus ruled out, so that an optimal gas-air mixture is burned in the cylinder. This saves fuel, the efficiency of the engine is significantly improved, and less pollutants are emitted for the benefit of mankind.

Erfindungsgemäß ist der Durchlauferhitzer so gestaltet (Pos. 5), daß er keine eigene Energiequelle benötigt. Der Durchlauferhitzer Pos. 5 ist durch die beiden Rohrstutzen an den Punkten a und b in eine beliebige Schlauchleitung eingebunden. Nach Inbetriebnahme des Motors M und Erreichen der erforderlichen Betriebstemperatur des Kühlwassers wird der Durchlauferhitzer Pos. 5 mit Wasser von ca. 80°C versorgt. Dieses im Durchlauferhitzer Pos. 5 so erwärmte Kühlwasser gibt einen Teil seiner Wärme an das durch den Durchlauf­ erhitzer Pos. 5 geführte Teilstück der Treibstoffleitung Pos. 4 ab. Hierdurch wird dem auf dem Weg durch dieses Teilstück der Treibstoffleitung Pos. 4 dem Treibstoff Wärme zugeführt, die zur Veränderung des Aggregatzustandes des flüssigen Treibstoffes erforderlich ist. Größe und Wärmemenge des Durchlauferhitzers Pos. 5 ist so bemessen, daß der hindurchfließende Treibstoff unterhalb der Siedepunktgrenze von Motorentreibstoffen bleibt.According to the instantaneous water heater is designed (item 5 ) that it does not require its own energy source. The instantaneous water heater, item 5, is integrated into any hose line through the two pipe sockets at points a and b . After starting up the motor M and reaching the required operating temperature of the cooling water, the instantaneous water heater pos. 5 is supplied with water of approx. 80 ° C. This so heated in the continuous-flow heater item 5 releases part of its heat to the section of the fuel line item 4 guided through the continuous-flow heater item 5 . As a result, the fuel is supplied to the fuel on the way through this section of the fuel line item 4, which heat is required to change the physical state of the liquid fuel. The size and quantity of heat of the instantaneous water heater, item 5, is dimensioned such that the fuel flowing through it remains below the boiling point limit of motor fuels.
