Description

Einrichtung zur Beheizung des Gemischstroms eines OttomotorsDevice for heating the mixture flow of a gasoline engine

Die Erfindung betrifft eine Einrichtung zur Beheizung des Gemischstroms eines Ottomotors, mit im Ansaugkanal angeordnetem elektrischem Widerstandsdraht.The invention relates to a device for heating the mixture flow of a gasoline engine, with in the intake duct arranged electrical resistance wire.

Eine derartige Einrichtung ist zum Beispiel aus der US - PS 3 492 457 bekannt. Die Heizleistung ist jedoch für eine zufriedenstellende Aufheizung des Gemisches und intensive Verdampfung des am Draht ausfallenden Kraftstoffs nicht ausreichend, um eine Verbesserung des Betriebsverhaltens des Motors während der Warmlaufphase zu erzielen. Zur Verbesserung der Abgaszusammensetzung und des Verbrauchs wird eine Verringerung der üblicherweise zugesetzten Brennstoffmenge angestrebt, was bei der bekannten Einrichtung praktisch nicht möglich ist.Such a device is known, for example, from US Pat. No. 3,492,457. The heating power is however for a satisfactory heating of the mixture and intensive evaporation of the precipitated on the wire Fuel insufficient to improve engine performance during to achieve the warm-up phase. To improve the exhaust gas composition and consumption, a The aim is to reduce the amount of fuel usually added, which is the case with the known device is practically impossible.

Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung eingangs genannter Art zu schaffen, die bei einfachem und robustem Aufbau einen ausreichenden Wärmeübergang ermöglicht.The invention is based on the object of creating a device of the type mentioned at the outset, which includes simple and robust construction enables sufficient heat transfer.

Diese Aufgabe wird gemäß den Merkmalen des Hauptanspruchs gelöst. Ausgestaltungen sind in den Unteransprüchen angegeben.This object is achieved according to the features of the main claim. Refinements are in the subclaims specified.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigen:An embodiment of the invention is shown in the drawing and will be described in more detail below described. Show it:

Figur 1 ein Saugrohr mit einer BeheizungFigure 1 shows a suction pipe with a heater

Fiqur 2 einen Schnitt gemäß der Linie II-II der Figur 1 mit einem angedeuteten Registervergaser.Fig. 2 shows a section along the line II-II of Figure 1 with an indicated register carburetor.

- 4 806I/I Fi.- 4 806I / I Fi.

Im Hals des Saugrohr 1 ist ein aus elektrischem Widerstandsdraht 2 gebildetes Paket 3 angeordnet. Die Endbereiche des Paketes sind in Ausnehmungen 4 aufweisende Isolierkappen 5 aufgenommen, wodurch eine thermische und elektrische Isolierung gegenüber dem Saugrohr erfolgt. Dadurch, daß das Paket 3 eigenstabil ist, wird die Montage des Paketes mit den aufgesteckten Isolierkappen 5 in, in der Saugrohrwandung befindliche Ausnehmungen 6 erleichtert. Es ist jedoch auch möglich, einen Zwischenflansch als Montageort zu wählen.In the neck of the suction tube 1, a package 3 formed from electrical resistance wire 2 is arranged. The end areas of the package are received in recesses 4 having insulating caps 5, whereby a thermal and electrical isolation from the intake manifold takes place. The fact that the package 3 is inherently stable is the assembly of the package with the plugged-on insulating caps 5 in recesses located in the suction tube wall 6 relieved. However, it is also possible to choose an intermediate flange as the mounting location.

Durch Versetzung des Drahtes in den Ebenen des Paketes wird ein Ausfällen des Kraftstoffs am Draht bewirkt, so daß die zugeführte elektrische Energie gezielt zum Verdampfen des Kraftstoffs eingesetzt wird und nicht praktisch ohne. Effekt an die Ansaugluft abgegeben wird.Moving the wire in the planes of the package causes the fuel to fail on the wire, so that the electrical energy supplied is specifically used to vaporize the fuel and not practically without. Effect is released to the intake air.

Durch Verwendung von Material mit positivem Temperaturkoeffizienten für den Widerstandsdraht wird die Stromaufnahme bei steigender Temperatur vermindert. Es kann auch ein Thermoschalter 7 vorgesehen sein, der in Abhängigkeit von der Motortemperatur die Energiezufuhr unterbindet. Bei der Verwendung dieser Einrichtung im Zusammenhang mit einem Registervergaser wird das Drahtpaket im Bereich der ersten Stufe im Ansaugkanal angeordnet. By using material with a positive temperature coefficient for the resistance wire, the power consumption is reduced as the temperature rises. It can a thermal switch 7 can also be provided, which, depending on the engine temperature, the energy supply prevents. When using this device in connection with a register carburetor, the wire package arranged in the area of the first stage in the intake duct.
