Description

BENZINVERDAMPFER k'UR OTTOkOTOREN PETROL EVAPORATOR k'UR GASOLINE

Das hn*-endungsgebiet der erfindung ist die Gemischaufbereitung für Ottomotoren.The hn * -end area of the invention is the mixture preparation for Gasoline engines.

zin Ausführungsbeispiel der erfindung ist in der Zeichnung dargestellt und wird wie folgt beschrieben.zin embodiment of the invention is shown in the drawing and is described as follows.

Das Benzin wird über eine Pumpe(2) aus dem Tank(1) angesaugt und in die Verdampfungskammer(4) gepumpt. Der Benzinstand wird durch einen Schwimmer(3) konstant gehalten. Der untere Teil der Verdampfungskammer ist als Wärmetauscher(5) ausgebildet.The petrol is sucked in from the tank (1) by a pump (2) and fed into the evaporation chamber (4) is pumped. The fuel level is controlled by a float (3) kept constant. The lower part of the evaporation chamber is used as a heat exchanger (5) educated.

Hier heizen die durchströmenden Auspuffgase das Benzin auf und verdampfen es.Here the exhaust gases flowing through heat up the gasoline and evaporate it.

gas verdampfte Benzin wird durch eine Leitung(6), in die eine regelbare Drosselung(7) eingebaut ist, zum Ansaugrohr(8) geführt, wo es sich mit der Ansaugluft vermischt.Gas vaporized petrol is fed through a line (6) into which a controllable Throttle (7) is installed, led to the intake pipe (8), where it is with the intake air mixed.

Wird zuviel Benzin verdampft, strömt es durch eine Rücklaufleitung(9) in den Tank zurück. Die Kegelung des Gemisches erfolgt über die Drosselklappe(1O) im Ansaugrohr(8) und die Drosselung(7) in der Dampfleitung(6). Die beiaen Drosselungen müssen aufeinander abgestimmt sein, wobei, ähnlich eier Einspritzregelung, auch Werte wie Motordrehzahl, Außentemperatur usw. berucksichtigt werden können.If too much gasoline evaporates, it flows through a return line (9) back in the tank. The cone of the mixture takes place via the throttle valve (1O) in the suction pipe (8) and the restriction (7) in the steam line (6). The two throttles must be coordinated with each other, whereby, similar to injection control, too Values such as engine speed, outside temperature, etc. can be taken into account.

Zum Start des Motors wird das Benzin im Verdampfer durch eine elektrische Heizspirale(11) erhitzt.To start the engine, the gasoline is in the evaporator by an electric Heating coil (11) heated.

Der Benzinverdampfer ähnelt dem von Carl Benz erfundenen Oberflächenvergaser. (Der Oberflächenvergaser ist beschrieben im "Auto-Lexikon Technik", Seite 104, herausgegeben von der Seitschrift "Auto Motor und Sport") 'r darf jedoch nicht mit diesem verwechselt werden. Der Unterschied zu ihm besteht darin, daß beim Benzinverdampfer in der Verdampfungskammer reiner Benzindampf entwickelt wird. Es bildet sich in der Verdampfungskammer also noch keir Benzin Luft Gemisch wie beim Oberflächenvergaser.The gasoline evaporator is similar to the surface carburetor invented by Carl Benz. (The surface carburetor is described in "Auto-Lexikon Technik", page 104, published from the inscription "Auto Motor und Sport") 'r must not be confused with this will. The difference to him is that the gasoline vaporizer is in the vaporization chamber pure gasoline vapor is developed. It forms in the evaporation chamber so nor a gasoline-air mixture as with the surface carburetor.

Vorteile: ta beim Benzinverdampfer der Kraftstoff gasförmig der Ansaugluft zugeführt wird, kann er sich wesentlich besser mit der Ansaugluft vermischen als flüssig angesaugter oder eingespritzter Kraftstoff. Dadurch ist eine Verbesserung des spezifischen Verbrauchs und eine Verminderung der giftigen Abgasbestandteile wie Kohlenmonoxid und Kohlenwasserstoff zu erwarten. Gegenüber dem Oberflachenvergaser läßt sich die Luftverhältniszahi exakter regulieren.Advantages: ta with gasoline vaporizers the fuel in gaseous form in the intake air is supplied, it can mix with the intake air much better than liquid sucked in or injected fuel. This is an improvement specific consumption and a reduction in toxic exhaust gas components expected such as carbon monoxide and hydrocarbon. Compared to the surface carburetor the air ratio can be regulated more precisely.
