Description
Die Erfindung betrifft eine Brennkraftmaschine, insbesondere Zweitaktbrennkraftmaschine, bei der die Ladung des Arbeitszylinders durch bei seinem Auspuffvorgang ausgelöste Druckwellen nach Abschluß der Einlaßöffnungen nach Druck und Menge erhöht wird, wobei in einer an den Arbeitszylinder angeschlossenen, die Abgase aufnehmenden Leitung oder einem Leitungssystem Prallflächen, z. B. in Gestalt einer Verengung der Leitung von solchem Querschnitt und solcher Entfernung vom Zylinder vorgesehen sind, daß die bei Eröffnung der Verbindung zwischen Zylinder und Leitung entstehende und darauf von der Prallfläche zurückgeworfene Druckwelle positiv ist, vor dem Wiederabschluß der Verbindungsöffnung in den Zylinder gelangt und dadurch den Druck der im Zylinder befindlichen Verbrennungsluft erhöht, nach Patent 946930.The invention relates to an internal combustion engine, in particular a two-stroke internal combustion engine, in which the charge of the working cylinder is triggered by during its exhaust process Pressure waves are increased in pressure and volume after the inlet openings are closed, wherein in a connected to the working cylinder, the exhaust gases receiving line or a pipe system baffles, z. B. in the form of a narrowing of the line of such a cross-section and such a distance from the cylinder that the one arising when the connection between the cylinder and the pipe is opened and on it pressure wave reflected from the baffle is positive before reclosing the connection opening in the cylinder and thereby the pressure in the cylinder Combustion air located increased, according to patent 946930.
Aufgabe der Erfindung ist es, deren vorteilhafte Anwendung auch bei mit Abgasturbinen zusammenarbeitenden Brennkraftmaschinen zu ermöglichen. Gelöst wird diese Aufgabe erfindungsgemäß dadurch, daß bei einer Maschine nach dem Hauptpatent die Prallflächen durch eine in die Abgasleitung eingeschaltete, an sich bekannte Abgasturbine gebildet werden. Der Ersatz der Prallflächen oder düsenförmigen Verengung durch das Schaufelsystem einer Abgasturbine ist ohne weiteres möglich, da die Druckwellen von dem Schaufelsystem in gleicher Weise zurückgeworfen werden wie von einer Prallfläche oder einer düsenförmigen Verengung.The object of the invention is their advantageous application also with to enable internal combustion engines working together with exhaust gas turbines. Solved this object is according to the invention in that in a machine according to the main patent the baffles by a known per se connected into the exhaust pipe Exhaust turbine are formed. The replacement of the baffles or nozzle-shaped constriction through the blade system of an exhaust gas turbine is easily possible because the pressure waves be thrown back from the shovel system in the same way as from a baffle or a nozzle-shaped constriction.
In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes schematisch dargestellt.The drawing shows an embodiment of the subject matter of the invention shown schematically.
In die Auspuffleitung a des Zylinders b ist im Abstand L vom Zylinder eine Abgasturbine c eingeschaltet, deren Schaufelsystem d die beim Eröffnen der Auspuffschlitze des Zylinders mit Schallgeschwindigkeit durch die Auspuffleitung laufende Druckwelle reflektiert. Der Abstand L der Turbine c vom Zylinder ist so bemessen, daß die an dem Schaufelsystem d zurückgeworfene positive Druckwelle vor Wiederabschluß der Auspuffschlitze in den Zylinder gelangt, so daß während der vorangegangenen Spülung in die Abgasleitung übergetretenes Spülmittel in den Zylinder -zurückgeschoben wird. Hierdurch erhöht sich der f)ruck im Zylinder.In the exhaust line a of the cylinder b , an exhaust gas turbine c is switched on at a distance L from the cylinder, the blade system d of which reflects the pressure wave running through the exhaust line at the speed of sound when the exhaust ports of the cylinder are opened. The distance L of the turbine c from the cylinder is dimensioned so that the positive pressure wave thrown back on the blade system d reaches the cylinder before the exhaust ports are closed again, so that the flushing agent that has passed into the exhaust line during the previous flushing is pushed back into the cylinder. This increases the f) jerk in the cylinder.
