Description

Doppeltwirkende Zweitakt-Brennkraftmaschine mit Kompressor Es sind einerseits Zweitakt Brennkraftmaschinen bekannt, mit auf der gleichen Kolbenstange sitzenden Arb.eits- und insbesondere größerem Ladekompressorkolben, bei denen Arbeits- und Kompressorzylinder während des Verdichtungshubs miteinander verbunden sind lind zufolge des größeren Verdichtungsverhältnisses im Kompressor, die Ladung aus dem Kompressor in den Arbeitszylinder übergeschoben wird.Double-acting two-stroke internal combustion engine with compressor There are on the one hand two-stroke internal combustion engines known, with on the same piston rod seated working pistons and, in particular, larger charge compressor pistons where working and compressor cylinders are connected to each other during the compression stroke due to the larger compression ratio in the compressor, the charge from the Compressor is pushed over into the working cylinder.

Andererseits sind Zweitakt-Brennkraftmaschinen bekannt, bei denen die in der Mitte des Zylinders angeordneten Auspuffschlitze von dem schmalen Kolben schon etwa 9o° vor der Totpunktlage der Kurbel freigegeben werden. Nach der Erfindung werden die Merkmale beider Maschinen vereinigt, um einen langsam laufenden, doppeltwirkendlon Explosionsmotor zu schaffen.On the other hand, two-stroke internal combustion engines are known in which the exhaust slots from the narrow piston located in the middle of the cylinder be released about 9o ° before the dead center position of the crank. According to the invention the features of both machines are combined to form a slow-running, double-acting dlon To create explosion engine.

Die Zeichnung stellt die Erfindung in Abb. i in einem Ausführungsbeispiel im senkrechten Längsschnitt dar.The drawing shows the invention in Fig. I in one embodiment in a vertical longitudinal section.

Abb. 2 zeigt den Einbau der Maschine für den Antrieb von Seitenradschiffen. Beide Abbildungen sind schematisch gehalten.Fig. 2 shows the installation of the machine for the drive of side wheel ships. Both figures are kept schematic.

Der im Zylindern des Explosionsmotors geführte Kolben .b ist durch seine Stange c unmittelbar mit dem Kolben d von wesentlich größerem Durchmesser eines Kompressors gekuppelt, dessen Zylindere den Hub des Motorkolbens b mitbestimmt. Der Arbeitszylinder a ist gegenüber dem Zylinder e des Kompressors verlängert, so da,ß in bekannter Weise der Kompressor ein größeres Verdichtungsverhältnis erhält. Der Kompressorkolben d drückt die zu beiden Seiten erzeugte Preßluft auf die entsprechenden Seiften des Motorkolbens b durch Umleitungsrohr f bzw. f. Die für den Einlaß der Preßluft dienenden Ventile g, g' sowie die für das Einspritzen des Brennstoffs bestimmten Ventile h, h' werden von der Kolbenstange e oder von der Welle aus in üblicher Weise gesteuert, desgleichen auch der Zündstrom.The piston .b guided in the cylinder of the explosion engine is directly coupled by its rod c to the piston d of a significantly larger diameter of a compressor, the cylinder of which also determines the stroke of the engine piston b. The working cylinder a is lengthened compared to the cylinder e of the compressor, so that the compressor receives a greater compression ratio in a known manner. The compressor piston d presses the compressed air generated on both sides onto the corresponding soaps of the motor piston b through bypass pipes f or f. The valves g, g 'serving for the inlet of the compressed air and the valves h, h' intended for the injection of the fuel become controlled by the piston rod e or by the shaft in the usual way, as is the ignition current.

PATENTANSPRUCH: Doppeltwirkende Zweitackt-Brennkraftmaschine mit Kompressor, bei welcher der Kolben des Arbeitszylinders sowie der größeren Durchmesser aufweisende Kolben des Kompressors auf derselben Kolbenstange sitzen und während des gemeinsamen Verdichtungshubes die Ladung aus dem ein größeres Verdichtungsverhältnis aufweisenden Kompressor in den. Arbeitsraumübergedrückt wird, dadurch gekennzeichnet, daß in an sich bekannter Weise der kurz gehaltene Kolben den in der Mitte des Arbeitszylinders angeordneten Auspuffschlitz annähernd 9o° vor der Totpunktlage überläuft, mit der Wirkung, daß der Arbeitskolben während des ersten Teiles des Rücklaufs bis zu; den Auspuffschlitzen die Verbrennungsgase ausschiebt und gleichzeitig der Kompressor den vom Arbeitskolben noch nicht bestrichenen Teil des Arbeitszylinders ausspült.PATENT CLAIM: Double-acting two-stroke internal combustion engine with compressor, in which the piston of the working cylinder and the larger diameter Pistons of the compressor sit on the same piston rod and during the joint The compression stroke takes the charge from the higher compression ratio Compressor in the. Working space is pressed over, characterized in that in in a manner known per se, the short piston held in the middle of the working cylinder arranged exhaust slot overflows approximately 9o ° before the dead center position, with the Effect that the working piston during the first part of the return up to; the Exhaust slots that push the combustion gases out and at the same time the compressor rinses out the part of the working cylinder that has not yet been coated by the working piston.
