Description

Regelung -des- Überladedruckes bei Brennkraftmaschinen mit Ladung aus Brennstoff, Sauerstoff und indifferentem Gas Es ist bekannt, daß bei Brennkraftmaschinen, welche nach dem im Patent 496 104 bezeichneten überladeverfahren mit Ladung aus Brennstoff, Sauerstoff und Abgas arbeiten, der überschuß an Abgasen gemeinsam mit dem in 'ihnen enthaltenen Kondenswasser durch ein Drosselventil ins Freie abströmt, wobei dieses Ventil zugleich Regelventil für den überdruck. des Arbeitsverfahrens ist. Da jede Druckschwankung im Abstrom der Gase die Maschinenleistung ändert, ist eine konstante Druckregelung für einen störungsfreien Beharrungszustand im Betrieb der Maschine Vorbedingung. Die gemeinsame Abführung der Abgase und des Wassers erfüllt diese Vorbedingung nicht, weil der Gasstrom vor dem Ventil und in der Abströmleitung durch Wasserpfropfen behindert wird, so daß Druckschwankungen auftreten.Regulation of the supercharging pressure in internal combustion engines with charge from fuel, oxygen and inert gas It is known that in internal combustion engines, which according to the overcharging process described in the patent 496 104 with charge Fuel, oxygen and exhaust gas work together with the excess exhaust gases the condensed water contained in them flows through a throttle valve into the open air, this valve at the same time regulating valve for the overpressure. of the working process is. Since every pressure fluctuation in the outflow of the gases changes the engine performance, is a constant pressure control for a trouble-free steady state in operation the machine precondition. The common discharge of exhaust gases and water is fulfilled this precondition is not, because the gas flow in front of the valve and in the discharge line is hindered by water plugs, so that pressure fluctuations occur.

Der vorliegende Erfindungsgedanke betrifft eine weitgehende Verhütung des vorhezeichneten Mangels. Zum Zweck einer empfindlichen Regulierung der zur Maschine zurückfließenden Verbrennungsgase auf einen konstanten Druck wird der Druckregler im Aussaß der Gase vom Wasserdurchlaß entlastet. Die erheblichen Mengen des ausgeschiedenen Verbrennungs- und Einspritzkühlwassers werden getrennt durch eine Pumpe abgeführt. Hierbei wird eine Pumpe verwendet, bei welcher der Durchfluß sowohl für Gas als auch für Wasser unabhängig von der Druckdifferenz zwischen Saug- und Dructueite auf eine annähernd konstante Fördermenge begrenzt ist. Die Fördermenge der Pumpe ist etwas größer bemessen als die größte im Betrieb der Maschine anfallende Menge des Kondens- und Einspritzwassers, so daß mit Sicherheit nur wasserarme Gase durch den Druckregler fließen.The present inventive concept relates to extensive prevention of the aforementioned defect. For the purpose of a sensitive regulation of the machine Returning combustion gases to a constant pressure is controlled by the pressure regulator Relieved of water passage in the outlet of the gases. The significant amounts of the excreted Combustion and injection cooling water are discharged separately by a pump. Here, a pump is used in which the flow rate for both gas and also for water regardless of the pressure difference between suction and pressure side is limited to an approximately constant flow rate. The delivery rate of the pump is dimensioned somewhat larger than the largest amount accruing in the operation of the machine of the condensation and injection water, so that with certainty only low-water gases through the pressure regulator flow.

Abb. i stellt eine im überladeverfahren nach Patent 496 104 arbeitende Brennkraftmaschinenanlage dar, bei der beispielsweise eine an den Kondensator - angeschlossene Zahnradpumpe für die getrennte Abführung des aus den Abgasen ausgeschiedenen Wassers sorgt. Die Abgase der Brennkraftmaschine a werden durch die Abgasleitung ia in den Kondensator b geleitet: -Aus dem Kondensator b führen zwei Abflußleitungen. c und w ins Freie oder für bestimmte Zwecke in eine Wasservörlage d mit einer Druckhöhe h entsprechend Abb. 2. - Das ausgeschi _-dene Wasser wird durch die Leitung w der Zahnradpumpe x zugeleitet, von welcher es unabhängig von der etwa vorhandenen Druck-@höhe.h abgeführt wird. Getrennt davon führt die Leitung c das vom Wasser befreite überschüssige Abgas über das Regelventile ab.Fig. I shows an internal combustion engine system operating in the supercharging process according to patent 496 104, in which, for example, a gear pump connected to the condenser ensures the separate discharge of the water separated from the exhaust gases. The exhaust gases from the internal combustion engine a are routed through the exhaust pipe ia into the condenser b: Two drain pipes lead out of the condenser b. c and w into the open air or, for certain purposes, into a water reservoir d with a pressure head h according to Fig. 2. - The discharged water is fed through the line w to the gear pump x, from which it can be pumped regardless of the pressure @ höhe.h is discharged. Separately from this, line c removes the excess exhaust gas from which the water has been removed, via the control valve.

Der Kreislauf der durch das Ventili und die Rückleitung f dem Gemischbilder g wieder zuströmenden Abgase, die Sauerstoffzufuhr bei i aus dem Behälter m und die Brennstoffzufuhr im Gemischbilder g aus dem Behälter k geht in der aus dem Patent 496 164 bekann ten Weise vor sich.The cycle of the exhaust gases flowing back through the valve and the return line f to the mixture generator g , the oxygen supply at i from the container m and the fuel supply in the mixture generator g from the container k takes place in the manner known from patent 496 164.
