Description

Zweitakt-Verbrennungskraftmaschinen bisheriger Barart häb@n -die »Nachteile schlechter Regelfähigkeit und ungenügender Spülung. Bei Verwendung von Ventilen ist infolge auftretender Beschleunigung der Steuerungsteile die erreichbare. Motordrehzahl beschränkt. Bekannt sind den --Arbeitszylinder---um-.gebende- zylindrische oder am Zylinderkopf arge-'-bxaehte flache Drehschieber, die Undichtigkeiten aufweisen und der Wärmeableitung des Arbeitszylinders entgegenstehen. Da die Antriebsorgane dieser Schieber außerhalb des Kurbelgehäuses liegen, entwickeln sie großen Lärm. Infolge Verschmutzungsgefahr durch äußere Einflüsse ist die Betriebssicherheit klein. -Die vorgeschlagene Drehzylindersteuerung hat a.lle-Antriebsorgane schmutzsicher und lärmarm im Kurbelgehäuse untergebracht. Alle Teile arbeiten mit konstanter Drehzahl. Es treten daher keine Beschleunigungen auf. Eimaß- und Auslaßöffnungen liegen so günstig in Zylinderlängsrichtung; 'daß eine sehr gute Spülung erreicht wird. Die Zylinderäüßenwandungen können voll zur Kühlung ausgenutzt werden.Two-stroke internal combustion engines of the previous type had the »disadvantages poor control and insufficient flushing. When using valves is the achievable one due to the acceleration of the control parts. Engine speed limited. Are known to the -working cylinder --- around-.gebende- cylindrical or on the cylinder head arge -'- bxaehte flat rotary valve with leaks and oppose the heat dissipation of the working cylinder. As the driving organs If these slide valves are outside the crankcase, they make a lot of noise. As a result of the risk of contamination from external influences, operational reliability is low. -The proposed rotary cylinder control has all drive elements dirt-proof and housed quietly in the crankcase. All parts work at constant speed. There are therefore no accelerations. The measuring and outlet openings are so favorable in the longitudinal direction of the cylinder; 'that a very good flush is achieved. the The outer walls of the cylinder can be fully used for cooling.

Die Steuerung für eine ZWeitakt-Blennkraftmaschine mit Gleichstromspülung wird dadurch erreicht, daß im Boden des Arbeitszylinders Aüslaßbohrungen vorgesehen sind, die bei einer Drehbewegung des Arbeitszylinders abwechselnd Öffnungen einer Auspuffplatte freigeben und verschließen, die in dem gegenüber dem Kurbelgehäuse unbeweglichen Zylinderkopf zwecks Regelung des Auslaßzeitpunktes verstellbar angebracht ist.The control for a two-cycle Blenn engine with direct current flushing is achieved in that outlet bores are provided in the bottom of the working cylinder are, the alternating openings of a during a rotary movement of the working cylinder Release and close the exhaust plate in the one opposite the crankcase immovable cylinder head adjustable for the purpose of regulating the exhaust time is.

Die Steuerung des Einlasses wird dadurch erreicht, daß am inneren Ende des Zylinders Einlaßschlitze vörgeseheri sind, die abwechselnd Öffnungen eines den Zylinder umschließenden Einlaßringes freigeben und verschließen, der zwecks Regelung des ' Einlaßzeitpunktes verstellbar am Kurbelgehäuse angeordnet ist. Bei Stern- und Reihenmotoren wird ein Zylinder angetrieben. Mittels Zahnkränzen am Zylinderfuß wird die Drehbewegung auf alle Zylinder übertragen. Bei Reihenmotoren kann eine alle Zylinder umspannende Kette die=Zyririder nnfireiben. Bei Sterrimoioren kann der Antrieb durch einen umlaufenden Zahnkranz. erfolgen.The control of the inlet is achieved that on the inner End of the cylinder inlet slots are provided, the alternating openings of a the cylinder surrounding inlet ring release and close, the purpose of Regulation of the 'inlet time is adjustable on the crankcase. at Radial and in-line engines are driven by one cylinder. By means of gear rings on the cylinder base the rotary motion is transmitted to all cylinders. In the case of in-line engines, a chain encircling all cylinders and rubbing = zyririders. With stereo speakers the drive by a rotating ring gear. take place.

Der Gegenstand der Erfindung ist beispielsweise in Fig. i bis 3 während des Spülvorganges dargestellt. Fig. i zeigt die Draufsicht auf den Zylinderkopf. Fig. 2 ist ein Längsschnitt durch den Arbeitszylinder a mit Kolben b, Antriebsrad c und Teil des Kurbelgehäuses d.The object of the invention is shown for example in Fig. I to 3 during the flushing process. Fig. I shows the top view of the cylinder head. Fig. 2 is a longitudinal section through the working cylinder a with piston b, drive wheel c and part of the crankcase d.

Fig. 3 ist ein Schnitt des Arbeitszylinders a in Höhe des Einlaßringes e. Der Kolben b hat seinen unteren Totpunkt erreicht. Der Arbeitszylinder a hat mit den Auslaßbohrungen f die Öffnungen g der Auspuffplatte h freigegeben. Gleichzeitig hat der Zylinder a mit den Einlaßschlitzen i am inneren Ende des Zylinders die Öffnungen k des den Zylinder a umspannenden Einlaßringes e freigegeben. Während die verbrannten Gase ausströmen, erfolgt die Füllung des Zylinders mit, Frischgasen. Es ist eine gute: Gleichstromspülung erreicht. Die Pfeile in Fig. 2 zeigen den Weg ' der verbrannten und der frischen Gase.Fig. 3 is a section of the working cylinder a at the level of the inlet ring e. The piston b has reached its bottom dead center. The working cylinder a has released the openings g of the exhaust plate h with the outlet bores f. At the same time, the cylinder a with the inlet slots i at the inner end of the cylinder has released the openings k of the inlet ring e surrounding the cylinder a. While the burned gases flow out, the cylinder is filled with fresh gases. It's a good: DC purge achieved. The arrows in Fig. 2 show the path of the burned and fresh gases.

Das- Antriebsrad c treibt den Zylinder a mit konstanter -Drehzahl an.The drive wheel c drives the cylinder a at a constant speed at.

Fig. q. zeigt einen Dichtring 1, der sich zwischen Zylinderboden und Auspuffplatte h befindet, der mittels Federring 7n eine gute Abdichtung ermöglicht.Fig. Q. shows a sealing ring 1, which is between the cylinder base and Exhaust plate h is located, which enables a good seal by means of spring ring 7n.

Fig. 5 ist eine graphische Darstellung einer Kurbelumdrehung.Fig. 5 is a graph of crank rotation.

o T = oberer Totpunkt, .. . u T = unterer Totpunkt, A ö = Auslaß öffnet, E-ö. = Einlaß öffnet, A s = Auslaß schließt, E s = Einlaß schließt.o T = top dead center, ... u T = bottom dead center, A ö = outlet opens, E-ö. = Inlet opens, A s = outlet closes, E s = inlet closes.

Aus Fig. 5. ist zu ersehen, daß die Spülung infolge des guten -Steuerquerschnitts nur eine kurze Zeit er--fordert.. Der Wirkungsgrade einer mit Drehzylindersteuerung versehenen Brennkraftmaschine ist höher als der .der Maschinen bisheriger Bauart.From Fig. 5 it can be seen that the flushing due to the good control cross-section only required for a short time .. The efficiency of one with rotary cylinder control provided internal combustion engine is higher than the .der machines of previous design.
