Vorrichtungen, die einen zusätzlichen Aufwand bedeuten. Devices that mean an additional effort.

So ist eine Vorrichtung bekannt, die aus einem Sprührohr, einer Düse und einem Befeuchtungskörper besteht, über welchen das Treibstoff-Luftgemisch hinweggeführt wird (DS-OS 843 100). Es ist ferner bekannt, destilliertes Wasser über eine Düse zuzuführen, deren Querschnitt über eine Steuereinrichtung in Abhängigkeit von der Drehzahl des Motors mittels eines in der Düse angeordneten Stiftes verändert wird (DE-OS 2 830 135). Weiterhin ist eine Vorrichtung bekannt, bei der über eine kurze Kapillare dam Treibstoff-Luftgemisch Wasser zugeführt wird. Das Wasser wird dabei aus einem Druckbehälter mittels einer mechanischen Regeleinrichtung in geeigneter Weise dosiert (DE-OS 2 622 872).For example, a device is known which consists of a spray tube, consists of a nozzle and a humidifier, over which the fuel-air mixture is carried away becomes (DS-OS 843 100). It is also known to supply distilled water through a nozzle, the cross section of which via a control device as a function of the speed of the engine by means of an in the Nozzle arranged pin is changed (DE-OS 2 830 135). Furthermore, a device is known in the case of the fuel-air mixture via a short capillary Water is supplied. The water is drawn from a pressure vessel by means of a mechanical one Control device dosed in a suitable manner (DE-OS 2 622 872).

Es ist ferner bekannt, zur Zudosierung von brennbaren Flüssigkeiten oder Wasser in Treibst off-Luft ge τη is ehe geeignete Zahnradpumpen zu verwenden (DE-OS 2 443 I66).It is also known for the metering of combustible Liquids or water in propellant air ge τη is ehe to use suitable gear pumps (DE-OS 2 443 I66).

Allen genannten Vorrichtungen haftet der Nachteil an, daß sie einen beträchtlichen Aufwand an zusätzlichen Regelelementen bedingen. Außerdem führt die Verwendung von Düsen mit darartig kleinen Querschnitten zu einer Beeinträchtigung der Funktionasicherheit.All of the devices mentioned have the disadvantage that they require a considerable amount of additional work Require control elements. In addition, the use of nozzles with dar-like small cross-sections leads to an impairment of the functional safety.

Ziel der ErfindungObject of the invention

Es ist das Ziel der Erfindung, den Aufwand bei der Zudosierung von Wasser in Treibstoff-Luftgemisehe von Viertakt-Otto-Motoren herabzusetzen und die Funktionssicherheit der Dosierung zu erhöhen. It is the aim of the invention, the effort in the Dosing of water in fuel-air mixtures from Reduce four-stroke Otto engines and increase the functional reliability of the metering.

Wesen der ErfindungEssence of the invention

- Die technische Aufgabe, die durch die Erfindung gelöst wird- The technical problem created by the invention is resolved

Der Erfindung liegt die Aufgabe zugrunde, eine Dosiervorrichtung für die Zudosierung von Wasser in Treibst of f-Luftgetnis ehe zu schaffen, die eine von der jeweiligen Treibstoff-Luftgeraischmenge unabhängige Dosierung einer annähernd konstanten Menge Wasser mit einem minimalen Aufwand neben einer hohen Zuverlässigkeit gewährleistet.'The invention is based on the object of providing a metering device for metering water into Drive of f-Luftgetnis to create the one of independent of the respective amount of fuel and air noise Dosing of an almost constant amount of water with minimal effort in addition to a high one Reliability guaranteed. '

- Merkmale der Erfindung- Features of the invention

Die Aufgabe wird erfindungsgemäß gelöst, indem hinter der Drosselklappe des Vergasers, im rechten Winkel zur Strömungsrichtung, eine in Strömungsrichtung abgeschrägte Kapillare angeordnet ist, wobei diese sowohl mit einer Zuleitung zum Wasservorratsgefaß, als auch mit einer Ausgleichs leitung, die in der Wandung unmittelbar vor dar Drosselklappe des Vergasers endet, verbunden ist.The object is achieved by behind the throttle valve of the carburetor, at right angles to the direction of flow, a beveled in the direction of flow Capillary is arranged, this both with a supply line to the water storage vessel, as also with a compensating line in the wall immediately before the carburetor throttle valve ends.

Die Erfindung soll an Hand des folgenden Beispiels näher erläutert werden:The invention is to be explained in more detail using the following example:

In einem Vergaser, der einen Viertakt-Otto-Motor mit dem notwendigen Treibstoff-Luftgeraisch versorgt, vt rd im Abstand von 10 mm hinter der Drosselklappenwelle eine Kapillare, die einen Innendurchmesser von ca. 0,9 mm aufweist, in der Mitte des Ansaugrohres angeordnet. An ihrer Spitze ist diese Kapillare in Strömungsrichtung abgeschrägt. Diese Kapillare steht über ein T-Stiick mit der Zuleitung zum WasservorratsgefäßIn a carburetor, which supplies a four-stroke Otto engine with the necessary fuel and air equipment, vt approx At a distance of 10 mm behind the throttle valve shaft, a capillary with an internal diameter of approx. 0.9 mm, arranged in the middle of the suction pipe. This capillary is at its tip in the direction of flow beveled. This capillary is connected to the supply line to the water storage vessel via a T-piece

Die Verbindung zwischen T-Stück und dem Waeaervorratsbehälter erfolgt ebenfalls über eine Kapillare. Der innere Durchmesser dieser Kapillare beträgt ebenfalls etwa 0,9 mm. Die Länge ist so gewählt, daß die eindosierte Wassermenge etwa 0,5 l/h beträgt.and the equalization line, the end of which is before the Throttle valve in the intake line ends in connection. The end of the compensation line is located about 20 mm away from the throttle valve shaft. The connection between the T-piece and the Waeaerstreservoir also takes place over a Capillary. The inner diameter of this capillary is also about 0.9 mm. The length is like that chosen that the metered amount of water is about 0.5 l / h.
