Description
Zweitaktver br ennungskraftmaschine. Bei Zweitaktverbrennungskraftmaschinen ist die Abwärme der Verbrennungsgase bis her nicht verwertet worden, weil die aus dem Zylinder austretenden Verbrennungs gase sich mit kalter Spülluft vermischen und infolgedessen eine für die Abwärme verwertung zu niedrige Temperatur an nehmen.
Durch die vorliegende Erfindung soll dieser Übelstand dadurch beseitigt werden, dass die aus dem Zylinder zuerst austreten den, heissen Verbrennungsgase von den küh leren, später austretenden, mit Spülluft ver mischten' Verbrennungsgasen getrennt ab geführt werden. Die zuerst austretenden heissen Verbrennungsgase und die später aus tretenden kühleren Verbrennuii"sgase können dabei unter Ausnutzung der Differenz ihrer Strömungsenergie voneinander getrennt wer den.
Die Auspuffleitung lässt sich zli diesem Zweck so ausbilden, dass sie eine Unter brechung aufweist, die von den mit höherer Geschwindigkeit austretenden Verbren nungsgasen überbrückt, von den kühleren, mit geringerer Strömungsenergie austreten den Verbrennungsga.sen@ dagegen zum Ab- strömen auf einem Weg geringeren Wider standes benutzt wird.
Ein _lusführungsbeispiel des Erfindung:- gregenstandes ist auf der Zeichnung zur Dar- ,stellun:; gebracht.
Der Kolben b arbeitet im Zylinder ri mit den Spülschlitzen i und den y Auspuff schlitzen d, die in üblicher Weise in einen Sammelraum c münden. Aus dem Sammel raum gelangen die Verbrennungsgase durch eine Düse e in einen mit zwei Ableitungen f und 9 versehenen Raum Ir.. Die -Mündung der Ableitung f ist der Düse gegenüber und in der Richtung der Düsenachse a.nzeorelnc#1-. Die zu Beginn der Auspuffperiode,
also vor der (Öffnung des Spülluftsehlitzes aus rlc#m Zylinder ausgestossenen und infolgedessen mit grösserer Geschwindigkeit und heisserer Temperatur als das nachfolgende Spülluft- abgasgemisch durch die Düse c hindurch- getriebenen Verbrennungsgase werden in folge ihrer grossen Geschwindigkeit durch den Raum h hindurch,
direkt in die Ab leitung f hineingeschleudert und durch diese hindurch zu der Abgaswärmeverw ertungs- stelle getrieben, während die nach Eröffnung der- Spülluftscblitwä aus denn Zylinder aus- gestossenen, daber mit Spülluft vermischten, <B>,
</B> ab-ekühlten und mit e-rheblich kleinerer Gre- I #q.Ilwilidickeit durch die Düse c hindurch nc triebeüen Gase den Gegendruck in der Leitung f nicht :wehr zu überwinden ver- niö@",en, so dass sie in dem Raum 1i, sich ver breiten. aus welchem sie durch die Leitung entweichen.
Auf diese -Weise wird mit einfachen -Mitteln erreicht.- dass nur die hei ssen, verwertbaren Verbrennungsgase der Abwärmeverwertunnsstelle zugeführt wer den. während der wertlose kältere Teil selbsttätig in die Atmosphäre entweicht.
Two-stroke internal combustion engine. In two-stroke internal combustion engines, the waste heat from the combustion gases has not yet been used because the combustion gases emerging from the cylinder mix with cold scavenging air and consequently take a temperature that is too low for waste heat recovery.
This drawback is to be eliminated by the present invention in that the hot combustion gases which emerge first from the cylinder are led separately from the cooler, later emerging, combustion gases mixed with scavenging air. The hot combustion gases that emerge first and the cooler combustion gases that emerge later can be separated from one another by utilizing the difference in their flow energy.
For this purpose, the exhaust line can be designed in such a way that it has an interruption that bridges over by the combustion gases exiting at a higher speed, while the cooler, exiting combustion gases with lower flow energy are less so to flow out Resistance is used.
An example of the invention: the object is on the drawing for illustration; brought.
The piston b works in the cylinder ri with the scavenging slots i and the y exhaust slots d, which open into a collecting space c in the usual way. The combustion gases pass from the collecting space through a nozzle e into a space Ir provided with two outlets f and 9. The mouth of the outlet f is opposite the nozzle and in the direction of the nozzle axis a.nzeorelnc # 1-. The at the beginning of the exhaust period,
So before the (opening of the scavenging air slot seat from rlc # m cylinder ejected and consequently with greater speed and hotter temperature than the subsequent scavenging air exhaust gas mixture through the nozzle c-driven combustion gases are driven through the space h due to their high speed,
thrown directly into the discharge line f and driven through it to the exhaust gas heat recovery point, while the cylinders expelled after the opening of the scavenging air were mixed with scavenging air, <B>,
</B> cooled down and with a considerably smaller size through the nozzle c through nc the gases do not drive the counterpressure in the line f: defend against overcoming vernio @ ", so that they in the space 1i, from which they escape through the pipe.
In this way, simple means are used to ensure that only the hot, usable combustion gases are fed to the waste heat recovery point. while the worthless colder part escapes automatically into the atmosphere.
