Description

Verfahren zum Betriebe von Brennkraftmaschinen mit Dampferzeugung und Zusetzung dieses Dampfes zur Zylinderladung Zusatz zum Patent 707952 Vorliegende Erfindung stellt eine weitere Ausgestaltung des Verfahrens zum Betriebe von Brennkraftmaschinen gemäß Patent 707 952, dar, bei dem durch die Abwärme der Maschine erzeugter überhitzter Dampf während des Verdichtungshubes einer ersten Stufe der Brennkraftmaschine zugeführt und nach der Verbrennung des Brenngasgemisches zusammen mit den Verbrennungsgasen zweistufig bis auf Außendruck entspannt wird.A method of operations of internal combustion engines with steam generation and clogging of this vapor to the cylinder charge additive patent 707 952 The present invention provides a further embodiment of the method of operations of internal combustion engines according to Patent 707 952, represents in which generated by the waste heat of the engine superheated steam during the compression stroke of a The first stage of the internal combustion engine is supplied and, after the combustion of the fuel gas mixture, is expanded in two stages to external pressure together with the combustion gases.

Bei diesem Verfahren ist die Überströmtemperatur, also die Endtemperatur der Teilentspannung in der ersten Stufe, obgleich sie niedriger liegt als bei einer normalen Maschine, immerhin noch so hoch, daß für die zweite Entspannungsstufe eine besondere bauliche Ausführung erforderlich wird, die den bei diesen Temperaturen auftretenden schwierigen Betriebsverhältnissen gerecht wird. Es ist nun bei Verbundbrennkraftmaschinen zwar schon bekannt, in die erste Stufe Wasser zur Kühlung der Verbrennungsgase zerstäubt einzuspritzen. Hierbei wird jedoch etwa 70% der vom Wasser aufgenommenen Wärme bei der Verdampfung in latente Wärme verwandelt und dadurch der Umwandlung in Arbeit entzogen.In this process, the overflow temperature is the final temperature the partial relaxation in the first stage, although it is lower than in one normal machine, at least so high that a special structural design is required, which at these temperatures difficult operating conditions that arise. It is now with compound internal combustion engines Although already known, water is atomized in the first stage to cool the combustion gases inject. Here, however, about 70% of the heat absorbed by the water is used the evaporation is converted into latent heat and thereby the conversion into work withdrawn.

Gemäß der, vorlfegenden Erfindung wird dieser Übelstand dadurch vermieden, daß die Überströmtemperatur herabgesetzt wird, ohne daß jedoch hierbei Wärme dem Arbeitsvorgang verlorengeht bzw. in eine Form verwandelt wird, in der sie nicht mehr in Arbeit umgesetzt werden kann.According to the present invention, this drawback is avoided by that the overflow temperature is reduced, but without the heat Operation is lost or transformed into a form in which it is not more can be put into work.

Die Erfindung besteht darin, daß der Überströmkanal von der ersten zur zweiten Stufe als Wärmeaustauscher ausgebildet .wird. In diesem wird dem Verbrennungsgas nach der Teilentspannung in der ersten Stufe beim Überströmen von dieser zur zweiten Stufe Wärme entzogen. Diese Wärme wird durch indirekten Austausch auf den aus Abwärme erzeugten Sattdampf des im Arbeitsvorgang verwendeten an der Verbrennung nicht teilnehmenden Stoffes übertragen und so zu seiner Überhitzung benutzt. Der größte Teil dieser Wärme wird nach Einleiten des nunmehr überhitzten Dampfes in den Verdichtungshub der Br ennkraftstufe im Verlaufe des Arbeitsvorganges in Arbeit umgewandelt.The invention consists in that the overflow channel from the first designed as a heat exchanger for the second stage .wird. In this is the combustion gas after the partial relaxation in the first stage when flowing over from this to the second Stage heat withdrawn. This heat is generated by indirect exchange on the waste heat generated saturated steam of the non-participating in the combustion used in the work process Transferred to the substance and used to overheat it. Most of this Heat is generated after the steam, which is now superheated, is introduced into the compression stroke the combustion power level is converted into work in the course of the work process.
