Die Erfindung betrifft eine Heizvorrichtung für das Gemisch .von Brennkraftmaschinen, bei welcher das Gemischansaugrohr von einem von den Auspuffgasen der Länge nach durchströmten Heizrohr quer durchsetzt und zugleich am Außenumfang von den Auspuffgasen umspült wird. Im Gegensatz zu den bekannten Heizvorrichtungen, bei welchen das Heizrohr zylindrisch ist und überall gleichenThe invention relates to a heating device for the mixture .von internal combustion engines, in which one of the exhaust gases flowed lengthwise through the mixture intake pipe The heating pipe is traversed transversely and at the same time the exhaust gases wash around the outer circumference. In contrast to the known heating devices in which the heating tube is cylindrical and the same everywhere
»o Querschnitt besitzt, ist erfindungsgemäß das Heizrohr als ein in der Strömungsrichtung der Auspuffgase sich verengendes Keilrohr mit dem angesaugten 'Gemischstrom entgegengerichteter Keilkante ausgebildet. Diese Bauart des Heizkörpers führt zu einer verbesserten Heizwirkung, da die das Keilrohr durchströmenden Auspuffgase einerseits beim Durchzwängen durch den der Keilkante entlang laufenden, stark zusammengeschnürten Teil des Rohrquerschnittes und andererseits infolge der Verengung des Heizkörpers in der Längsrichtung in ihrer Bewegung stark gehemmt werden und dadurch eine erhebliche Drosselung erfahren, die zu einer bedeutenden Wärmeabgabe an die Keilkante und zu einer sehr hohen Erhitzung desselben führt. Dadurch wird in weiterer Folge aber auch das auf die Keilkante auftreffende Gemisch sehr stark vorgewärmt und die Wärme der»O has a cross-section, is that according to the invention Heating pipe as a wedge pipe that narrows in the direction of flow of the exhaust gases formed with the sucked in 'mixture flow opposite wedge edge. This type of the radiator leads to an improved heating effect, since the flow through the wedge tube Exhaust gases on the one hand when forced through the tightly constricted running along the edge of the wedge Part of the pipe cross-section and on the other hand due to the narrowing of the radiator in the Longitudinal direction are strongly inhibited in their movement and thus a considerable Experienced throttling, leading to significant heat dissipation to the wedge edge and to leads to a very high heating of the same. As a result, however, also the mixture hitting the edge of the wedge is very strongly preheated and the heat of the

Man hat bei Heizvorrichtungen für das Gemisch von Brennkraftmaschinen zwar schon in das Gemischansaugrohr einen von den Auspuffgasen außen umspülten und innen durchströmten hohlen Heizkegel mit dem angesaugten Gemischstrom entgegengerichteter Spitze eingebaut, doch bildet der an der Spitze befindliche Teil des Hohlkegelinneren einen toten Raum, den die Auspuffgase nicht durchströmen, so daß eine wesentliche Erwärmung der Kegelspitze, die übrigens dem ankommenden Gemischstrom auch eine erheblich geringere Angriffsfläche bietet als eine Keilkante, · nicht eintritt. Auch würde die mit der neuen Heizvorrichtung erzielte günstige Heizwirkung nicht erreicht werden können, wenn man in an sich ebenfalls bekannter Weise das in das Gemischansaugrohr einzubauende Heizrohr sich zwar im Innern verjüngen und dann wieder erweitern ließe, es aber mit einem zylindrischen Außenmantel versehen würde; es würde dann die Rohrwand wegen ihrer großen Materialanhäufung eine nur niedrige und jedenfalls erheblich niedrigere Temperatur nehmen können als beim Gegenstand der Erfindung die verhältnismäßig dünnwandige Keilkante des Keilrohres.One already has with heating devices for the mixture of internal combustion engines In the mixture intake pipe one of the exhaust gases was flushed around the outside and flowed through on the inside Hollow heating cone built in with the sucked in mixture flow at the opposite tip, but the one at the tip forms Part of the hollow cone interior has a dead space through which the exhaust gases do not flow, so that a substantial warming of the cone tip, which incidentally the incoming Mixture flow also offers a considerably smaller contact surface than a wedge edge, does not occur. The favorable heating effect achieved with the new heating device would also be achieved cannot be achieved if the in the mixture intake pipe to be installed heating pipe tapered inside and then could be expanded again, but it would be provided with a cylindrical outer jacket; it Then the pipe wall would only have a low and because of its large accumulation of material in any case, can take a considerably lower temperature than in the subject matter of the invention the relatively thin-walled wedge edge of the wedge tube.

Ein mit Flanschen r, 2 zum Einbau in die Auspuffleitung 3 der Brennkraftmaschine versehenes, geschlossenes Gehäuse 4 wird von einem in Flanschen 5, 6 zum Einbau in die Saugleitung 7 der Brennkraftmaschine endigenden Rohr 8 durchsetzt. Dieses wird von einem in der Strömungsrichtung der Auspuffgase sieh verengenden Keilrohr 9 durchquert, welches die Keilkante 10 dem in der Richtung der Pfeile α (Fig. 2) zur Brennkraftmaschine strömenden Arbeitsgemisch zukehrt. Die Auspuffgase ziehen zum Teil in der Richtung der Pfeile b um das Rohr 8 herum, undA closed housing 4 provided with flanges r, 2 for installation in the exhaust line 3 of the internal combustion engine is penetrated by a pipe 8 ending in flanges 5, 6 for installation in the suction line 7 of the internal combustion engine. This is traversed by a wedge tube 9 which narrows in the flow direction of the exhaust gases and which faces the wedge edge 10 to the working mixture flowing in the direction of the arrows α (FIG. 2) to the internal combustion engine. The exhaust gases partly pull in the direction of the arrows b around the pipe 8, and
