Description
■;·'■'■'■ Die Erfindung richtet sich auf Verb^ennungskraftmaschinen, bei welchen flüssiger Brennstoff fein zerstäubt eingespritzt wird, und zwar soll die Entzündung des auf diese Weise gebildeten Gemisches von zerstäubtem Brennstoff und Verbrennungsluft nicht wie bei den sogenannten Glühkopfmotoren durch die heißen Wandungen des Verbrennungsraumes selbst, sondern durch geeignete Zündvorrichtungen, vorzugsweise durch einen elektrischen. Zünder, unabhängig von dem Zeitpunkt der Brennstoffeinspritzung bewirkt werden. Hierbei kommt es darauf an, daß der Verbrennungsraum bzw. ein in ihm angeordneter Einsatz den fein zerstäubten flüssigen Brennstoff nicht bereits von selbst während der Kompressionsperiode zur Entzündung bringen darf, damit Frühzündungen vermieden werden. ■; · '■' ■ '■ The invention is directed to verb ^ ization engines, in which liquid fuel is injected finely atomized, namely the ignition of the on this Wise formed mixture of atomized fuel and combustion air does not like in the so-called hot-head engines through the hot walls of the combustion chamber itself, but by suitable ignition devices, preferably by an electric one. Detonator, regardless of the timing the fuel injection can be effected. It is important here that the combustion chamber or one arranged in it Do not use the finely atomized liquid fuel by itself during the The compression period is allowed to cause inflammation so that premature inflammation is avoided.
ao Diese Aufgabe löst die Erfindung in der Weise, daß die völlig glatte Wandung des Verbrennungsraumes, in welchem die Bildung des Brennstoffluftgemisches erfolgt, durch den ikühlenden Einfluß des Zylindermantels oder durch die Einwirkung der Verbrennungsluft oder durch beides auf einer Temperatur gelhalten wird, welche nur bis zur Vergasung 'des fein zerstäubt eingeführten Brennstoffes führt, worauf das Luftgemisch in bekannter Weise mittels elektrischer Funken o. dgl. zu : zünden ist. Hierbei kann die Wirkung des eingespritzten Brennstoffes den jeweiligen Betriebsverhältnissen angepaßt werden. Bei Volllast z. B., d. h. bei maximaler Brennstoffeinspritzung und maximaler Wärmeabgabe an die Verbrennungskammer, erreicht diese durch die entsprechende Abströmung, nur eine solche Temperatur, daß eine Selbstzündung höchstens im oberen Totpunkt ohne schädlichen Einfluß möglich wäre. Bei Teilbelastung dagegen ist die Temperatur entsprechend niedriger infolge einer kleineren Menge des eingespritzten Brennstoffes und eines etwaigen Überschusses an Arbeitsluft, jedoch noch so hoch, daß eine genügende Verdampfung des Brennstoffes gewährleistet wird] wobei an die Wirkung der k elektrischen Zündung natürlich höhere Anforderungen gestellt werden..The invention solves this problem in such a way that the completely smooth wall of the combustion chamber in which the fuel-air mixture is formed is kept at a temperature which is only up to leads to gasification of the finely atomized fuel introduced, whereupon the air mixture is to be ignited in a known manner by means of electrical sparks or the like. The effect of the injected fuel can be adapted to the respective operating conditions. At full load z. B., ie with maximum fuel injection and maximum heat release to the combustion chamber, this reaches through the corresponding outflow, only such a temperature that auto-ignition would be possible at most in top dead center without harmful influence. At part load, however, the temperature is correspondingly lower of course, higher demands are made as a result a smaller amount of injected fuel and a possible excess of the working air, however, still so high that a sufficient evaporation of the fuel is ensured] to the effect of the k electric ignition. .
Zur Ausführung der Erfindung kann die entsprechend verdickte Wandung des Verbrennungsraumes benutzt werden, doch dient dem Zwecke vorzugsweise ein in das Gehäuse des Verbrennungsraumes eingesetzter Körper, der aus einem dem Rußansatz nicht unterliegenden Metall, wie Nickel, Neusilber, besteht, während die zylindrische · oder konische Gestalt, die Abmessungen und der Abstand des Einsatzes vom Gehäuse- derart zu wählen sind, daß die kühlende Wirkung der Arbeitsluft oder des Zylindermantels oder beider den angegebenen Verhältnissen angepaßt sind. Wichtig ist, daß die Wand des Verbrennungsfaumes oder des Einsatzes keinerlei Vorsprünge besitzt, welche zu Rußlagerungen führen und glühend werden könnten.To implement the invention, the correspondingly thickened wall of the combustion chamber can can be used, but the purpose is preferably a body inserted into the housing of the combustion chamber, which consists of a metal that is not subject to soot, such as nickel, nickel silver, while the cylindrical or conical shape, the dimensions and the spacing of the Use of the housing should be selected in such a way that the cooling effect of the working air or the cylinder jacket or both of the are adapted to the given conditions. It is important that the wall of the combustion chamber or the insert does not have any projections that lead to soot deposits and could get glowing.
