KAISERLICHESIMPERIAL
PATENTAMTPATENT OFFICE
Es ist bekannt, bei Verbrennungskraftmaschinen zwecks Wärmeabführung aus den Wandungen des Verbrennungsraumes Dampf im Kühlmantel durch Verdampfungskühlung zu erzeugen und diesen Dampf in den Zylinderraum einzuführen. Man wandte jedoch dieses letztere Mittel bisher selten an, da das verdampfende Wasser durch Kesselstein ablagerung usw. die Kühlräume versetzte, auch machtIt is known in internal combustion engines for the purpose of dissipating heat from the walls of the combustion chamber to generate steam in the cooling jacket by evaporative cooling and this steam into the cylinder chamber to introduce. However, this latter remedy has seldom been used, since it is vaporizing Water displaced by scale build-up, etc., also makes the cold rooms
ίο die dicke Wandung großer Maschinen die Wärmeabführung recht unwirksam.ίο the thick walls of large machines Heat dissipation quite ineffective.
Die Erfindung verwendet zu diesem Zweck destilliertes Wasser, welches mit Hilfe der Motorabgase selbst erzeugt wird. Dabei kann die Regulierung der einzuführenden Dampfmenge entsprechend der Motorleistung völlig selbsttätig erfolgen. Außerdem erfolgt die Verdampfung des Wassers in einem Raum, der stets mit dem Verbrennungsraum in offener Verbindung steht, so daß die Wandung beliebig dünn gehalten werden kann, da sie keine Beanspruchung erfährt.The invention uses distilled water for this purpose, which with the aid of the Engine exhaust itself is generated. The regulation of the amount of steam to be introduced can be used take place completely automatically according to the engine power. In addition, the Evaporation of the water in a room that is always open with the combustion chamber Connection is so that the wall can be kept as thin as desired, since it experiences no stress.
In Fig. ι ist α der Zylinder einer Verbrennungskraftmaschine, ζ. Β. eines Dieselmotors, dessen Abgase durch die Rohrleitung b abgeführt werden. In letzterer ist die Verdampferschlange c angeordnet, die von dem Hochbehälter d aus mit frischem Wasser versorgt wird. Die erzeugten Dämpfe strömen in die durch Kühlwasser f gekühlte Schlange e, in der sie niedergeschlagen werden. Das sich unten ansammelnde destillierte Wasser drückt die Pumpe g dann durch ein Rückschlagventil η in den Mantel des Zylinders a, ' dessen Konstruktion in Fig. 2 genauer dargestellt ist. Es 3S ist in den oberen Teil des Zylinders α eine Büchse k eingesetzt, die an ihrem äußeren Umfang etwa schraubenförmige Nuten h trägt. Mit dem Zylindermantel bilden diese Nuten Kanäle, denen das Wasser durch Rohr m zugeführt wird. Durch die Verbrennungswärme wird das Wasser in den Kanälen h erwärmt und beim Weiterfließen verdampft und damit durch Wärmebindung die' Entstehung übermäßiger Temperaturen in der Zylinderwand 4^ verhindert. Der erzeugte Dampf strömt durch Öffnungen i, die sich oben befinden, in den Zylinder; dies wird nun weniger geschehen, wenn der Druck im Zylinder hoch ist, als bei geringeren Drücken, also am Ende der Expansion während des Auspuffens, Ansaugens und am Anfang der Kompression. Dies ist aber auch beabsichtigt, da aus wärmetheoretischen Gründen die Zuführung des Kühlmittels gerade in den genannten Perioden des Kreisprozesses erwünscht ist.In Fig. Ι, α is the cylinder of an internal combustion engine, ζ. Β. of a diesel engine, the exhaust gases of which are discharged through pipe b . In the latter, the evaporator coil c is arranged, which is supplied with fresh water from the elevated tank d. The vapors generated flow into the coil e, which is cooled by cooling water f , in which they are precipitated. The distilled water that collects at the bottom then presses the pump g through a check valve η into the jacket of the cylinder a, the construction of which is shown in greater detail in FIG. It 3 S a bushing k is inserted into the upper part of the cylinder α , which carries approximately helical grooves h on its outer circumference. With the cylinder jacket, these grooves form channels to which the water is fed through pipe m. The water in the ducts h is heated by the heat of combustion and evaporates as it continues to flow, thus preventing excessive temperatures from developing in the cylinder wall 4 through thermal bonding. The generated steam flows into the cylinder through openings i located at the top; this will now happen less when the pressure in the cylinder is high than with lower pressures, i.e. at the end of the expansion during exhausting, suction and at the beginning of the compression. However, this is also intended because, for reasons of thermal theory, the supply of the coolant is particularly desirable in the periods of the cycle mentioned.
Da das destillierte Wasser praktisch chemisch rein ist, können die Wandungen h nicht verschmutzen, auch in.das Zylinderinnere werden keine Fremdstoffe eingeführt.Since the distilled water is practically pure, the walls can not pollute h, even in.das cylinder inside no foreign substances are introduced.
Bei geringer Motorleistung muß die Menge des einzuführenden Wassers bzw. Dampfes verrin-If the engine power is low, the amount of water or steam to be introduced must be reduced.
gert, bei zunehmender Leistung dagegen erhöht werden, ganz entsprechend der kleineren oder größeren Wärmeerzeugung im Zylinder durch Verbrennung von weniger oder mehr Brennstoff. Dieses regelt sich bei der Anlage gemäß der Erfindung völlig selbsttätig. Denn bei geringerer Motorleistung nimmt nämlich auch der Wärmegehalt der Abgase ab, und da diese die Wasserverdampfung in der Schlange c besorgen, wird auch weniger destilliertes Wasser erzeugt und somit auch weniger in den Zylinder eingeführt. Umgekehrt wird bei höherer Leistung auch mehr Frischwasser durch die Abgase verdampft und daher auch mehr destilliertes Wasser für die Kühlung durch die Pumpe g in den Zylinder gedrückt. Bedingung hierbei ist natürlich, daß die Pumpe das ihr zufjießende Wasser, einerlei, ob viel oder wenig, selbsttätig gleichmäßig weiterfördert.gert, on the other hand, are increased with increasing power, according to the smaller or larger heat generation in the cylinder through the combustion of less or more fuel. This regulates itself completely automatically in the system according to the invention. This is because with a lower engine output the heat content of the exhaust gases also decreases, and since these take care of the evaporation of water in coil c , less distilled water is also produced and thus less is introduced into the cylinder. Conversely, with a higher output, more fresh water is evaporated by the exhaust gases and therefore more distilled water is also pressed into the cylinder for cooling by the pump g. The condition here is, of course, that the pump automatically continues to deliver the water flowing to it, regardless of whether it is a lot or a little.
