Description
Siedekühlung mit Überhitzung des Dampfes für die Brennstoff- und Gemischbeheizung: Das Hauptpatent behandelt eine Siedekühlung, bei welcher das siedende Kühlgut, bevor es in den Rückkühler gelangt, durch die Heizmäntel des Saugrohres, des Vergasers und des Brennstotfvorwärmers geleitet wird, um den Brennstoff, und besonders das Gemisch, so wirksam wie möglich zu beheizen.Evaporative cooling with superheating of the steam for fuel and mixture heating: The main patent deals with evaporative cooling, in which the boiling refrigerated goods before it gets into the dry cooler, through the heating jackets of the suction pipe, of the gasifier and the fuel preheater is directed to the fuel, and especially that Mixture to heat as effectively as possible.
Das vorliegende Zusatzpatent will diese Art der Siedekühlung ergänzen. Bei einem Brennstoff, für dessen Hauptbestandteile der Tau-Punkt über iooo' liegt, genügt eine Dampftemperatur von io5 bis 115' nicht, um einen genügenden Teil des Brennstoffes bis zum Augenblick der Zündung zu vergasen. Man hat versucht, dem durch Erhöhung der Siedetemperatur abzuhelfen, ist dabei aber sehr bald an eine Grenze gekommen, bei welcher jede Temperaturerhöhung durch eine unverhältnismäßig große Drucksteigerung erkauft werden mußte, welche die Betriebssicherheit gefährdete und bei Fahrzeugen besonders schwere Rückkühler nötig machte. Anderseits werden die Laufmäntel und die Wände des Kompressionsraumes, da sie innen vom Feuer berührt werden, auf ihrer wasserberührten, Wärme abgebenden Seite erheblich heißer, als das innen vom Gemischstrom gekühlte, bemantelte Saugrohr. Um Cberhitzungen der Kompressionsraumwände bzw. der Ventilbrücken zu vermeiden, darf man daher die Siedetemperatur des ganzen Systems nicht so weit erhöhen:, als es für eine möglichst lebhafte Verdampfung schon im Saugrohr wünschenswert wäre.The present additional patent aims to supplement this type of evaporative cooling. In the case of a fuel for whose main components the dew point is above iooo ', a steam temperature of 10-5 to 115 'is not enough to generate a sufficient part of the To gasify fuel up to the moment of ignition. You tried to get through it Remedying an increase in the boiling temperature will soon reach its limit come, at which every increase in temperature by a disproportionately large Pressure increase had to be bought, which the operational safety endangered and made particularly heavy dry coolers necessary for vehicles. On the other hand will be the barrel mantle and the walls of the compression room, as it touches the inside of the fire are considerably hotter than the heat-emitting side that comes into contact with water the jacketed intake manifold, cooled on the inside by the mixed flow. About overheating of the compression chamber walls or to avoid the valve bridges, one must therefore adjust the boiling point of the whole Do not increase the system as much as it does for the most vigorous evaporation possible in the intake manifold would be desirable.
Diese Schwierigkeiten bezwingt die vorliegende Erfindung, indem sie den Dampf überhitzt, wie es bei Kesselanlagen üblich ist, und ihn darauf zur Beheizung des Saugrohres verwendet.The present invention overcomes these difficulties by superheats the steam, as is customary in boiler systems, and then uses it to heat it of the suction pipe is used.
Hierfür bieten sich verschiedene Wege. Der Kühlraum des Kompressionsraumes kann z. B. von dem des Laufmantels getrennt und der Sattdampf im Kühlmantel des Kompressionsraumes erzeugt, dagegen. im Kühlraum des Laufmantels überhitzt werden. Bei :Motoren mit abnehmbaren Zylinderköpfen läßt sich diese Art der Siedekühlung ohne Schwierigkeiten nachträglich einrichten. Bei jedem Motor aber kann man die Auspuffgase in einfacher Weise für die Beheizung des Überhitzers heranziehen.There are various ways of doing this. The cold room of the compression room can e.g. B. separated from that of the barrel jacket and the saturated steam in the cooling jacket of the Compression space generated, however. overheated in the cooling chamber of the barrel jacket. This type of evaporative cooling can be used for: engines with removable cylinder heads set up afterwards without difficulty. But with every engine you can Use exhaust gases in a simple manner for heating the superheater.
Diese Ausführung ist in der Zeichnung dargestellt. Durch die Krümmer i gelangt der aus dem Kühlgut erzeugte Frischdampf zunächst in den Flüssigkeitsabscheider z, danach durch die Leitung 3 als Sattdampf von geringer Feuchtigkeit in den Überhitzer. Dieser besteht nach der Zeichnung in einem Rohr 5, das in die Auspuffleitung hineingelegt ist, -kann aber in mancherlei anderer. Weise -ausgebildet werden. Durch die gegabelte Leitung 6 wird der überhitzte Dampf auf die Krümmer des Saugrohres geleitet und nimmt dann weiter, wie nach dem Hauptpatent, seinen Weg durch -die Mäntel des Saugrohres, des Vergasers und des etwaigen Brennstoffvorwärmers nach dem Kühler. An irgendeiner Stelle dieses Weges vereinigt er sich mit dem durch das Rohr .1 aus dem Flüssigkeitsabscheider abgesaugten Flüssigkeit.This version is shown in the drawing. Through the bends i the live steam generated from the refrigerated goods first reaches the liquid separator z, then through line 3 as saturated steam of low moisture in the superheater. According to the drawing, this consists of a pipe 5 which is placed in the exhaust line is, but can in many other things. Way to be educated. Through the forked Line 6, the superheated steam is directed to the manifold of the suction pipe and then continues, as according to the main patent, its way through the jackets of the suction pipe, the carburetor and any fuel preheater after the cooler. Anyone Point of this path it joins with that through the pipe .1 from the liquid separator aspirated liquid.
In dieses Rohr kann ein Hahn 7 eingebaut werden. Der Querschnitt des Rohres ¢ sowie des Hahnes 7 wird dann zweckmäßig so bemessen, daß bei etwa halb geöffnetem Hahn gerade alle Flüssigkeit abgesaugt wird, welche der Dampftrockner a abscheidet, der gesamte Dampf aber durch den i`berhitzer strömt. Wird der Hahn 7 weiter geöffnet, so wird auch ein Teil des Dampfes den kürzeren Weg durch das Rohr .1 nehmen. Man erhält dann weniger, aber höher erhitzten Dampf.A tap 7 can be installed in this pipe. The cross section of the Tube ¢ and the valve 7 is then appropriately dimensioned so that at about half With the tap open, all the liquid is sucked off, which the steam dryer a separates, but all of the steam flows through the superheater. Will the rooster 7 is opened further, some of the steam will also take the shorter route through the Take tube .1. Less, but more heated steam is then obtained.
Wenn dagegen der Hahn 7 stärker gedrosselt wird, so geht auch ein Teil des Wassers mit durch den Überhitzer, und es entsteht mehr, aber weniger noch erhitzter Dampf. Ein anderer Hahn in Leitung 3 kann weitere Regelmöglichkeiten schaffen. Mit Hilfe der vorliegenden Zusatzerfindung kann also die Beheizung des Saugrohres nicht nur ohne Drucksteigerung ganz erheblich verschärft, sondern auch der Eigenart des zu verwenelenden Brennstoffes jederzeit in einfachster Weise angepaßt werden.If, on the other hand, the cock 7 is throttled more strongly, it also works Part of the water with the superheater, and there is more, but less heated steam. Another tap in line 3 can create further control options. With the help of the present additional invention, the heating of the intake manifold not only tightened considerably without increasing the pressure, but also the peculiarity of the fuel to be used can be adapted at any time in the simplest possible way.
Auf diese Weise wird eine wesentlich schonendere und geregeltere Beheizung des Gemisches möglich, als wenn man das Gemischrohr unmittelbar mit Auspuffgasen beheizen würde.In this way, heating is much gentler and more regulated of the mixture possible, as if the mixture pipe was directly exposed to exhaust gases would heat.
