Zweitaktbrennkraftmasohine mit LadezylinderTwo-stroke combustion engine with charging cylinder
Die nicht vorveröffentlichte Hauptpatentanmeldung Nr. 22 47 147 betrifft eine Zweitakt-Hubkolben-Brennkraftmaschine mit parallel oder geneigt zum Arbeitszylinder angeordnetem Ladepumpenzylinder, bei der Pumpenkolben und Arbeitskolben durch die Kurbelwelle angetrieben sind, und der Pumpenkolben als Rohrschieberkolben, mit einer, den Überströmkanal steuernden öffnung ausgebildet ist, wobei der durch den Kolbenboden und die rohrschieberähnliche Erweiterung gebildete Raum durch eine im wesentlichen parallel zur Kolbenlängsachse verlaufende Trennwand in eine mit Luft beaufschlagte erste Kammer und in eine mit einem Kraftstoff-Luft-Gemisch beaufschlagte zweite Kammer unterteilt ist, bei der jeder dieser Kammern mind, ein Verbindungskanal zugeordnet ist.The main patent application No. 22 47 147, which was not previously published relates to a two-stroke reciprocating internal combustion engine with a charge pump cylinder arranged parallel or inclined to the working cylinder, in which the pump piston and working piston are driven by the crankshaft, and the pump piston as a tubular slide piston, is formed with an opening that controls the overflow channel, the opening formed by the piston head and the pipe slide-like opening Extension formed by a space essentially parallel to the Piston longitudinal axis extending partition into a first chamber acted upon by air and into one with a fuel-air mixture acted upon second chamber is divided, in which each of these chambers is assigned at least one connecting channel.
Es hat sich nun gezeigt, daß die in dem Hauptpatent dargestellte Lösung, die Unterteilung des durch die rohrschieberähnliche Erweiterung gebildeten Raumes noch weiter verbessert werden kann, wenn die räumliche Trennung der beiden Kammern erhalten bleibt, auch wenn der Pumpenkolben sich im unteren Totpunkt befindet.It has now been shown that the solution presented in the main patent, the subdivision of the pipe slide-like Expansion of the space formed can be further improved if the spatial separation of the two chambers is maintained, even if the pump piston is at bottom dead center.
Deshalb wird erfindungsgemäß ein Rohr vorgesehen, welches in eine der beiden Kammern hineinragt. Eine weitere, vorteilhafte Ausführung besteht darin, daß dem Einlaßkanal, durch welchen ein Kraftstoff-Luft-Gemisch zugeführt wird und/oder dem Einlaßkanal, durch den Luft zugeführt wird, ein Rückschlagventil zugeordnet ist.Therefore, a pipe is provided according to the invention, which in a the two chambers protrudes. Another advantageous embodiment is that the inlet channel through which a fuel-air mixture is supplied and / or a check valve is assigned to the inlet channel through which air is supplied.
Durch derartige Ausgestaltung ist es möglich, das Verdichtungsverhältnis der beiden vollständig voneinander getrennten Kammern verschieden zu gestalten.Such a configuration makes it possible to adjust the compression ratio to make the two completely separate chambers different.

In der Zeichnung ist ein Ausführungsbeispiel des Gegenstandes der Erfindung dargestellt. Es zeigt:In the drawing, an embodiment of the subject matter of the invention is shown. It shows:
Fig. 1 einen Längsschnitt durch ein Ausführungsbeispiel mit einem Rohrschieberkolben, der durch eine Trennwand in zwei Kammern unterteilt ist, wobei in eine der Kammern ein Rohr hineinragt. 1 shows a longitudinal section through an embodiment with a tubular slide piston which is divided into two chambers by a partition wall, a tube protruding into one of the chambers.
Pig. 2 einen Schnitt längs der Linie II - II in Fig. 1. Pig. 2 shows a section along the line II - II in FIG. 1.
Bei dem Beispiel nach Fig. 1 und 2 ist der Pumpenkolben 4 durch eine zylindrische Trennwand 20" in die Kammern 21" und 22" unterteilt. Durch das in die Kammer 22" hineinragende Rohr 28 bleibt die räumliche Trennung der beiden Kammern erhalten, auch wenn der Pumpenkolben 4 sich im unteren Totpunkt befindet. Durch den Einlaßkanal 30 bezieht die Kammer 22" über ein Rückschlagventil 29 ein Kraftstoff-Luft-Gemisch.In the example according to FIGS. 1 and 2, the pump piston 4 is inserted into the chambers 21 "and 22" through a cylindrical partition 20 ". divided. As a result of the tube 28 protruding into the chamber 22 ″, the spatial separation of the two chambers is maintained, too when the pump piston 4 is at bottom dead center. Through the inlet channel 30, the chamber 22 "includes a Check valve 29 is a fuel-air mixture.
Die Kammer 21" bezieht eine Luftladung als Variante zum Hauptpatent über ein Rückschlagventil 29 durch den Einlaßkanal Jl.The chamber 21 ″ refers to an air charge as a variant of the main patent via a check valve 29 through the inlet channel Jl.
Das Überschieben der Ladungen von den Kammern 21" und 22" in den Arbeitszylinder geschieht wie im Beispiel nach Fig. 1 und 2 im Hauptpatent.The shifting of the charges from the chambers 21 "and 22" into the working cylinder takes place as in the example according to FIGS. 1 and 2 in Main patent.
