Description
Viertakt-Brennkraftmaschine Das Bestreben, mit einem kleinen Motor eine große Leistung zu erzielen, wirkt bekanntlich darauf hin, mit der Drehzahl so hoch zu gehen, wie es nur irgend möglich ist, da hiervon die Wirtschaftlichkeit der Fahr-und Flugzeuge in hohem Maße abhängig ist.Four-stroke internal combustion engine The endeavor with a small engine It is well known that achieving a high output works with the speed to go as high as it is possibly possible, because of this the profitability the driving and aircraft is highly dependent.
Die größtmöglichste Drehzahl ist bekanntlich hauptsächlich abhängig von dem Lieferungsgrad des Saughubes.The highest possible speed is known to be mainly dependent on the delivery rate of the suction stroke.
Wenn man gleichbleibende Leistungen bei Jeder Drehzahl erreichen will, muß naturgemäß die Einzelladung um so größer sein, je langsamer der Motor läuft, um so kleiner, je mehr Explosionen auf die Zeiteinheit entfallen.If you want to achieve consistent performance at every speed, Naturally, the slower the engine runs, the greater the individual charge, the smaller the more explosions there are in the unit of time.
Da nun bei den üblichen Viertaktmotoren bei etwa 2500 bis 3ooo Touren in der Minute der Saughub des Kolbens nicht mehr ausreicht, den Zylinder mit Gas zu füllen, ist man dazu übergegangen, das Gas mittels eines vom Motor angetriebenen Ventilators (Kompressor) in den Zylinder zu pressen.Since the suction stroke of the piston is no longer sufficient to fill the cylinder with gas with the usual four-stroke engines at around 2,500 to 3,000 revolutions per minute, the gas has been fed into the cylinder by means of a fan (compressor) driven by the engine press.
Die vorliegende Erfindung betrifft nun einen automatischen Viertaktkompressormotor, bei dem der teure, kraftraubende Turbinenkompressor in Wegfall kommt und bei welchem durch Zuführung von Zusatzgas, aus dem als Ladepumpe wirkenden Kurbelgehäuse, eine dem Turbokompressor gleichkommende Zylinderfüllung und Leistung erreicht wird.The present invention relates to an automatic four-stroke compressor engine, in which the expensive, exhausting turbine compressor is no longer needed, and in which one by supplying additional gas from the crankcase acting as a charge pump, a Cylinder charge and power equivalent to that of the turbo compressor are achieved.
Bekannt gewordene Motoren dieser Art haben jedoch den schwerwiegenden Nachteil, daß infolge ihrer komplizierten Konstruktion nicht nur die Betriebssicherheit und Lebensdauer sehr in Frage gestellt wurden, sondern überhaupt eine nennenswerte Leistungssteigerung nicht erreicht werden konnte, z. B. beim Nachladen des Gemisches durch vom Kolben gesteuerte Schlitze wegen des Flammenüberschlags ins Kurbelgehäuse oder durch eine an den Zylinder angesetzte Ventilkammer wegen des schädlichen Raumes und Nachbrennens, oder beim Nachladen von nur reiner Luft sogar durch ein Kolbenventil wegen der schlechten Durchmischung der Ladung.However, engines of this type that have become known have the serious one Disadvantage that due to their complicated construction not only the operational safety and lifespan were very much in question, but one worth mentioning in general Increase in performance could not be achieved, e.g. B. when reloading the mixture through slots controlled by the piston because of the flashover into the crankcase or by a valve chamber attached to the cylinder because of the harmful space and afterburning, or even through a piston valve when reloading clean air only because of the poor mixing of the cargo.
Entgegen diesen vorher beschriebenen Ausführungen gelangt bei vorliegender Erfindung Zusatzgas durch einen am Zylinder angebrachten Kanal vom Kolben gesteuert in das Kurbelgehäuse und von hier durch ein im Kolbenboden sitzendes Ventil in den Zylinder. Diese Art der Zusatzgemischzuführung, welche durch langwierige Versuche ermittelt wurde, gestattet eine Mehrleistung von 6o °!a gegenüber dem üblichen Viertaktmotor.Contrary to these previously described statements, the present one arrives Invention additional gas controlled by the piston through a duct attached to the cylinder into the crankcase and from here through a valve seated in the piston crown into the Cylinder. This type of additional mixture feed, which through lengthy experiments was determined, allows an additional power of 60 °! a compared to the usual four-stroke engine.
Der Erfindungsgegenstand ist auf beiliegender Zeichnung in einem Ausführungsbeispiel veranschaulicht.The subject of the invention is shown in the accompanying drawing in an exemplary embodiment illustrated.
In Fig. i und z ist A Zylinder, B Kolben, C Kurbelgehäuse, D Kolbenventil, F_ Ansaugkanal für Zusatzgas, F Saugventil (normal), G Auspuffventil, Hl und H2 Vergaser.In Fig. I and z, A is cylinder, B piston, C crankcase, D piston valve, F_ intake port for additional gas, F suction valve (normal), G exhaust valve, Hl and H2 carburetor.
Der Arbeitsvorgang ist nun folgender: Durch einen am Zylinder A angebrachten Kanal E und einer in der Zylinderwand befindlichen Öffnung, 3#elche der Kolben B steuert, wird dem Kurbelgehäuse C vom Vergaser H2 Gasgemisch zugeführt. Dies geschieht beim Viertaktmotor zweimal. Ebenfalls wird dieses Gas vom Kolben zweimal komprimiert. Bei der eigentlichen Saugperiode gelangt also das Gasgemisch von zwei Seiten in den Zylinder, und zwar durch das üblich gesteuerte Einlaßventil F vom Vergaser H' einerseits sowie durch ein in den Kolben B gebautes automatisches oder gesteuertes Überdruckventil D andererseits.The process is now as follows: By means of an attached to cylinder A. Channel E and an opening in the cylinder wall, 3 # elche the piston B controls, gas mixture is supplied to crankcase C from carburetor H2. this happens at the Four-stroke engine twice. This gas is also compressed twice by the piston. During the actual suction period, the gas mixture enters from two sides the cylinder, through the normally controlled inlet valve F of the carburetor H ' on the one hand, as well as an automatic or controlled one built into the piston B. Pressure relief valve D on the other hand.
Diese beiden Ventile arbeiten jedoch nicht gleichzeitig, sondern unmittelbar hintereinander, und zwar öffnet sich bei der Saugperiode zuerst das normal gesteuerte Einlaßventil F, wenn der Kolben den oberen Totpunkt 0T erreicht hat (Fig. i).However, these two valves do not work simultaneously, but directly one after the other, namely the normally controlled one opens first during the suction period Inlet valve F when the piston has reached top dead center 0T (Fig. I).
Der Kolben saugt nun durch dieses Ventil Gas bis etwa ioo° nach dem 0T; dann schließt das Ventil F, und im Verlauf der weiteren Kolbenbewegung nach dem unteren Totpunkt UT, also etwa 8o°, wird das Kolbenventil D durch den im Kurbelgehäuse herrschenden Überdruck geöffnet, und das dort zusammengepreßte Gas strömt nun von hier aus in den Zylinder (Fig. a). Der Vorteil dieser Ventileinstellung ist eine bessere Regulierung der Drehzahlen sowie reduziertes Auspuffgeräusch infolge niedriger Kolbendrücke, was durch vollständiges Abdrosseln des Zusatzvergasers H2 erreicht wird, da sich der Kolben durch das Ventil F nur ioo° Gas saugen kann, gegenüber i8o° des normalen Viertaktes. Ein nicht unwesentlicher Vorteil dieses Motors ist auch noch die erhöhte Betriebssicherheit, da beim Versagen des normalen Ventils F (Federkipphebel, Gestängebruch usw.) der Motor infolge seiner Gaszuführung durch das Kolbenveiltil immer noch in Betrieb gehalten wird und die Leistung eines normalen Viertakters erreicht. In diesem Falle öffnet sich das Kolbenventil schon durch das Vakuum des leeren Zylinders.The piston now sucks gas through this valve up to about 100 ° after 0T; then the valve F closes, and in the course of the further piston movement it closes the bottom dead center UT, ie about 80 °, the piston valve D is through the in the crankcase prevailing overpressure opened, and the compressed gas there now flows out here out into the cylinder (Fig. a). The advantage of this valve setting is one better regulation of the speeds and reduced exhaust noise as a result of lower Piston pressures, which is achieved by completely throttling the additional carburetor H2 as the piston can only suck in 100 ° of gas through valve F, opposite i8o ° of the normal four-stroke. A not insignificant advantage of this engine is also the increased operational reliability, since the failure of the normal valve F (spring rocker arm, broken linkage, etc.) the motor through its gas supply the piston valve is still kept operating and the performance of a normal one Four-stroke achieved. In this case, the piston valve opens through the Vacuum of the empty cylinder.
