Description

Zweitakt-Brennkrafitmaschine Die vorliegende Erfindung betrifft einen Zweitaktmotor mit Stufenkolben und bezweckt die Verbesserung der Entleerung des Zylinders unter gleichzeitiger Füllung mit frischem Gemisch.Two-stroke fuel engine The present invention relates to a Two-stroke engine with stepped piston and aims to improve the drainage of the Cylinder with simultaneous filling with fresh mixture.

Nach der Erfindung soll die Zuführung des frischen Gemisches in einem früheren Zeitpunkt stattfinden als bei den bekannten Motoren. Das Gemisch muß demnach schon beim höheren Duck in den Zylinder einströmen. Um dieses zu erreichen, ist der Oberströmkanal durch Ventile gegen die Stufenkolbenpumpe und KurbelkastenpRUnpe verschlossen, so daß er bei verschlossenem Ventil einen in sich abgeschlossenen Raum bildet, der durch :ein Ventil. von den Verbrennungsraum getrennt ist und als Speicherraum für die Stufenkolbenpumpe dient.According to the invention, the supply of the fresh mixture in one take place earlier than with the known engines. The mixture must therefore already flow into the cylinder at a higher pressure. To achieve this is the overflow channel through valves against the stepped piston pump and crankcase pump closed, so that it is a self-contained when the valve is closed Space that forms through: a valve. is separated from the combustion chamber and as Storage space for the stepped piston pump is used.

Durch diese Ausbildung des Überströlnkanals weist dieser der Kurbelkastenpumpe gegenüber einen Überdruck auf, durch den das Gemischeinlaßventi1 für dien Verbrennungsraum bereits früher geöffnet wird, als wenn in. dem überströmkanal der Druck der Kurbelkastenpumpei herrscht, wie das bei den bekannten Motoren der Fall ist.Due to this design of the overflow channel, it faces the crankcase pump compared to an overpressure through which the mixture inlet valve for the combustion chamber is opened earlier than when the pressure of the crankcase pump in the overflow channel prevails, as is the case with the known engines.

Die Erfindung ist in den Zeichnungen beispielsweise dargestellt. Abb. i ist ehr. senkrechter Querschnitt durch die Mitte, Abb. 2 ein waagerechter Querschnitt durch den Arbeitsraum. Es ist i der Arbeitsraum; 3 und 3a der Stufenkolben, 9 bzw. 9a, 91) der Eänlaß des Gasgemisches, 7 :ein schmaler ringförmiger Raum um den Arbeitskolben, ein schmaler Kanal, der das Kurbelgehäuse mit dem Einlaß des komprimierten Gases in dem Arbeitsraum verbindet. a, b und C sind Ventile. 6 ist der Auspuff. io sind die schmalen Schlitze im Arbeitsraum für den Auslaß der Rückstände, und i i ist ein Ringkanal, in den diesle Schlitae münden.The invention is illustrated in the drawings, for example. Fig. I is Ehr. vertical cross-section through the middle, Fig. 2 a horizontal cross-section through the working area. It is i the work space; 3 and 3a the stepped piston, 9 and 9a, 91) the inlet of the gas mixture, 7: a narrow annular space around the working piston, a narrow channel which connects the crankcase with the inlet of the compressed gas in the working space. a, b and C are valves. 6 is the exhaust. io are the narrow slots in the working space for the outlet of the residues, and ii is an annular channel into which these slits open.

Beien Niedergang des Stufenkolbens wird im Ringraum 7 eine Luftverdünnung erzielt, und dadurch füllt sich dieser Raun dhrrch :dien Kanal 9 finit Gas. Beim Hochgang wird dieses Gas zusammengedrückt und öffnet das Ventil c, durch welches das Gas i den Kanal a eintritt und in- ihm Vorkompression erzeugt. Gleichzeitig ist durch den Kanal gv das Gas in das Kurbelgehäuse getreten, das behn Niedergang des Kolbens komprxmüert wird. Die Rückstände werden nach dem Niedergang des Kolbens dadurch - restlos aus dem Arbieätsraum entfernt, daß das im Kanal z doppelt vorkomprtirnierte Gas vorn. obren her in den Arbeitsraum tritt und die Rückstände vor sich hertreibt, bis sie durch die zahlreichen schmalen Kanäle io ins Freie gelangen. Hierauf wiederholt sich der Vorgang in derselben Weise.When the stepped piston descends, air is diluted in the annular space 7 achieved, and thereby this space is filled by the channel 9 finite gas. At the Hochgang this gas is compressed and opens the valve c, through which the gas i enters the channel a and generates precompression in it. Simultaneously the gas has entered the crankcase through duct gv, the behn companionway of the piston is compressed. The residue will be after the downfall of the piston as a result - completely removed from the workspace, that the precompressed twice in channel z Front throttle. Steps into the work area above and drives the residues in front of you, until they get outside through the numerous narrow canals. Then repeated the process works in the same way.
