Description

Vergaser mit Regelung der Verbrennungslufttemperatur Bei Kraftfahrzeugmotoren wechselt die Motorbelastung sehr häufig und in weiten Grenzen zwischen Leerlauf und Volleistung. Das im Vergaser gebildete Gemisch wird den Verbrennungsräumen durch die Saugleitung zugeführt, deren Querschnitt den Gemischmengen bei höchster Motorbelastung angepaßt sein muß. Bei gedrosseltem Motor nehmen die Gemischgeschwindigkeiten im Vergaser und in der Zuleitung zu den Verbrennungsräumen ab, die Durchgangszeiten des Gemisches durch den Vergaser und die Saugleitung entsprechend zu. Dadurch neigt das Brelnn,Stoff-Luft-Genlisch zum Zerfall auf seiuem Wege zum Verbrennungsraum, und die Gemischzusammensetzung der Ladungen der einzelnen Zylinder wird ungleich. Deshalb müssen so reiche Gemische verwendet werden, daß das ärmste Gemisch eines Zylinders noch verbrennt. Die Folge ist eine- Unwirtschaftlichkeit des Drosselbetriebes der Motoren und ungleichmäßiger Motorgang.Carburettor with regulation of the combustion air temperature in motor vehicle engines the engine load changes very frequently and within wide limits between idling and full power. The mixture formed in the carburetor passes through the combustion chambers the suction line, the cross-section of which corresponds to the amount of mixture at the highest engine load must be adapted. When the engine is throttled, the mixture speeds increase Carburetor and in the supply line to the combustion chambers, the transit times of the mixture through the carburetor and the suction line accordingly. This tends to the roaring, substance-air-genlish to decay on its way to the combustion chamber, and the mixture composition of the charges of the individual cylinders becomes unequal. Therefore so rich mixtures must be used that the poorest mixture is one Cylinder is still burning. The consequence is an inefficiency of the throttle operation of the engines and uneven engine speed.

Man hat diesen Mangel dadurch zu mildern versucht, daß man die Wandungen der Saugleitung des Vergasers heizt. Dadurch sind zwar Verbesserungen für den Drosselbetrieb erzielt worden, aber andererseits wird das Gemisch im oberen Belastungsbereich des Motors überhitzt und die Füllung und Verbrennung verschlechtert. Man hat auch eine mit der Füllung des Motors veränderliche Vorwärmnug der Vergaserwände benutzt. Diese Maßnahme hat aber den Nachteil, daß die Temperaturregelung des Heizmittels (Abgase) der Vergaserwände nur schleppend die @Tergaserwandtemperatur und erst hiernach die Gemischtemperatur beeinflußt. Die Temperaturangleichung des Gemisches bleibt hinter dem üblichen raschen Belastungswechsel zurück.Attempts have been made to alleviate this deficiency by removing the walls the suction line of the carburetor is heating. This improves the throttle operation has been achieved, but on the other hand, the mixture is in the upper load range of the The engine overheats and the filling and combustion deteriorate. You also have one With the filling of the engine, variable preheating of the carburettor walls is used. These The measure has the disadvantage that the temperature control of the heating medium (exhaust gases) of the carburetor walls only slowly the @Tergaserwand temperature and only after that the Mixed temperature influenced. The temperature adjustment of the mixture remains behind the usual rapid change in load.

Man hat auch in die Luftzuleitung zum Vergaser ein von Hand verstellbares Regelorgan für Kaltluft und Warmluft eingeschaltet. Da die Temperaturregelung der Luft bestimmten verwickelten Gesetzmäßigkeiten folgen muß, versagen die von -Hand geregelten Organe.There is also a manually adjustable air supply line to the carburetor Control element for cold air and warm air switched on. Since the temperature control of the Air must follow certain intricate laws, those of -hand fail regulated organs.

Es sind ferner Vergaser gebaut worden, bei welchen zwei zwangläufig gekuppelte, als Drosselorgan wirkende Sektoren im Vergaser die dem Vergaser zuströmenden Mengen von Kaltluft und Warmluft mitregeln. Dabei treten Kaltluft und Warmluft in zwei ungemischten Strömen in den Düsenraum ein, so daß dieser auf der Warmluftseite überhitzt und auf der Kaltluftseite überkühlt wird. Infolge dieses Mangels einer einheitlichen Lufttemperatur im Mischraum ist die Gemischbildung in diesem Vergaser unregelmäßig und unvollkommen.Carburettors have also been built, two of which are compulsory Coupled sectors in the carburetor that act as a throttle device and those that flow towards the carburetor Also regulate the quantities of cold air and warm air. Cold air and warm air come in two unmixed streams into the nozzle space, so that it is on the warm air side is overheated and overcooled on the cold air side. As a result of this lack of one uniform air temperature in the mixing room is the mixture formation in this carburetor irregular and imperfect.

Gemäß der vorliegenden Erfindung ist ein Wechselventil für Kaltluft und Warmluft vor dem Vergaser mit der Gemischdrossel derart gekuppelt, daß der Kaltluftanteil im Verhältnis zum Warmluftanteil mit der Eröffnung der Gemischdrossel zunimmt. Die Zeichnung zeigt ein Ausführungsbeispiel der neuen Temperaturregelung. Von dem Motor a werden die Abgase durch die Auslaßleitung c abgeleitet. Die Gemischbildung erfolgt in dem Vergaser h, welcher am Saugrohr b angeschlossen ist und welchem die Verbrennungsluft in einer Zuleitung zugeführt wird. In dieser Zuleitung liegt ein Luftvorwärmer e, in welchen die zu heizende Verbrennungsluft bei f einströmt. Das Gemischdrosselorgan i wird mittels Gestänge h zur Änderung der Motorbelastung verstellt. In der Luftleitung zum Vergaser ist ein Regelorgan g für Kaltluft und Warmluft eingebaut. Dieses ist gemäß dem Erfindungsgedanken durch das Gestänge n, m, l mit dem Gemischdrosselorgan i des Motors gekuppelt, derart, daß der Kaltluftanteil im Verhältnis zum Warmluftanteil mit der Eröffnung des Ge= mischdrosselorgans i zunimmt. Durch die gegenseitige Winkelstellung der Gestängehebel L und za kann man die Winkelausschläge des Temperaturregelorgans g und des Drosselorgans i ungleichförmig machen, so daß z. B. im ersten Teil der Drosseldrehung aus voller Öffnungsstellung des Drosselorgans 1 das Temperaturregelorgan g den Warmluftkanat schleppend öffnet und umgekehrt bei der ersten Öffnungsdrehung des Drosselorgans i aus Leerlaufstallung die Öffnung des Kaltluftkanals schleppend erfolgt. Man kann auch in die Gestängeverbindungen n, an, l eine Kurvenführung bekannter Bauart einfügen und dadurch jede gewünschte Bewegungsvariation zwischen den Regelorganen i und g herbeiführen.According to the present invention, a changeover valve for cold air and warm air upstream of the carburetor is coupled to the mixture throttle in such a way that the proportion of cold air in relation to the proportion of warm air increases with the opening of the mixture throttle. The drawing shows an embodiment of the new temperature control. From the engine a, the exhaust gases are discharged through the exhaust pipe c. The mixture is formed in the carburetor h, which is connected to the intake manifold b and to which the combustion air is fed in a feed line. In this supply line there is an air preheater e, into which the combustion air to be heated flows in at f. The mixture throttle element i is adjusted by means of a linkage h to change the engine load. A regulating element g for cold air and warm air is installed in the air line to the carburetor. According to the concept of the invention, this is coupled to the mixture throttle element i of the engine by the linkage n, m, l , in such a way that the proportion of cold air in relation to the hot air element increases with the opening of the mixture throttle element i. Due to the mutual angular position of the linkage lever L and za you can make the angular deflections of the temperature control member g and the throttle member i non-uniform, so that z. B. in the first part of the throttle rotation from the full open position of the throttle member 1, the temperature control member g opens the Warmluftkanat slowly and vice versa with the first opening rotation of the throttle member i from idle stall the opening of the cold air duct takes place slowly. A curve guide of a known type can also be inserted into the linkage connections n, an, l, thereby bringing about any desired variation in movement between the regulating elements i and g.
