Description
Zweitaktbrennkraftmaschine mit einem Turbogebläse Die Erfindung bezieht sich auf eine Zweitaktbrennkraftmaschine mit einem Turbogebläse nach Patent 638 367.Two-stroke internal combustion engine with a turbo fan The invention relates refers to a two-stroke internal combustion engine with a turbo fan according to patent 638 367.
Nach dem Hauptpatent sind die Laufräder der Abgasturbine und des Gebläses fest miteinander gekuppelt. Zwischen der Welle des Turbogebläses und der Kurbelwelle der Brennkraftmaschine ist eine Freilaufkupplung vorgesehen. so daß die Laufräder bei stärkerer Maschinenbelastung unabhängig von der Maschinemvelle mit höherer Drehzahl laufen können, bei geringer Belastung aber, bei der die Abgase unzureichend sind, von der lUaschinenwelle angetrieben werden. Bei kleiner Belastung u.td insbesondere beim Anlassen der l')rennkraftmaschine kommt es darauf an, daß die Arbeitszylinder mit einer gewissen, wenn auch verminderten L-uftm,-nge gespült werden. In diesem Sinne kann das übersetzungsverhältnis für den Antrieb zwischen der Kurbelhelle und der Welle des Turbogebläses so niedrig ";wählt werden, daly die geförderte Luftmenge gleich oder kleiner ist als das Ilub,.-olutneii der Arbeitszylinder.According to the main patent, the impellers of the exhaust gas turbine and the fan are firmly coupled to each other. Between the turbo blower shaft and the crankshaft an overrunning clutch is provided for the internal combustion engine. so that the impellers in the case of a higher machine load, independent of the machine shaft with a higher speed can run, but at low loads, where the exhaust gases are inadequate, driven by the machine shaft. In the case of small loads and especially When starting the engine, it is important that the working cylinder be flushed with a certain, albeit reduced, air volume. In this Meaning can be the transmission ratio for the drive between the crank light and the shaft of the turbo blower so low "; can be selected, daly the conveyed air volume is equal to or less than the ilub, .- olutneii of the working cylinder.
Gemäi3 der Erfindung wird nun außer der zwischen Gebläse und Maschinenwelle wirksamen Freilaufkupplung eine weitere Freilaufkupplung vorgesehen, die ein Zurückbleiben einzelner Stufen des Gebläses und der Turbine im Falle der Sperrun" des erstgenannten Freilaufs ermöglicht. Die Spülung der Arbeitszylinder bei ungenügender Leistung der Abgasturbine wird also dadurch gesichert, dab nur ein Teil des Gebläses unter Sperrung des einen Freilaufs angetrieben wird. Die übrigen Gebläsestufen sowie das Turbinenlaufrad, die auf Grund der Wirkung des erfindungsgemäßen Freilaufs zurückbleiben. brauchen nicht so rasch beschleunigt zu werden wie die 1Iotorwelle, und die Beanspruchung der Triebteile wird auf diese Weise herabgesetzt. Wenn mit steigender Behistung der Maschine die Drehzahl der Turbine zunimmt und die Drehzahl der Brenn--kraftmaschine selbst übersteigt, wird auch dieser letzte Teil des Gebläses von der Turbine angetrieben, wobei der erfindungsgemäße Freilauf sperrt und der erste sich selbsttätig löst. Diese Art des Antriebes wird somit allen vorkommenden Betriebsverhältnissen gerecht.According to the invention, in addition to the one between the fan and the machine shaft Effective one-way clutch provided another one-way clutch, which is left behind individual stages of the fan and the turbine in the event that the former is blocked Freewheel enabled. The rinsing of the working cylinder in case of insufficient performance the exhaust gas turbine is thus secured, that only part of the fan is below Blocking of one freewheel is driven. The other fan stages as well as that Turbine impeller, which remain due to the effect of the freewheel according to the invention. do not need to be accelerated as quickly as the 1Iotorwelle, and the stress the drive parts are reduced in this way. If with increasing discomfort of the machine, the speed of the turbine increases and the speed of the internal combustion engine increases exceeds itself, this last part of the fan is also driven by the turbine, whereby the freewheel according to the invention locks and the first is released automatically. This type of drive is therefore suitable for all operating conditions.
Eine Ausführungsform des Erfindungsgedankens ist auf der Zeichnung im Schema chirgestellt.One embodiment of the inventive concept is on the drawing shown in the scheme.
Das Laufrad a der Turbine und die beiden Stufen 6 und. c des Gebläses besitzen eine gemeinsame Welle e. Die dritte Gebläsestufe d wird bei ausreichender Abgasenergie unter Sperrung der erfindungsgemäßen Freilaufkupplung /ebenfalls von der Welle e des Turbogebläses angetrieben. Bei geringer Abgasenergie dagegen und insbesondere beim Anlassen der Maschine ist die Freilaufkupplung j gelöst, und die Gebläsestufe d wird unter Sperrung des anderen Freilaufs g über die Zahnräder h, j von der Maschinenwelle k mitgenommen. In einem Querschnitt ist die Wirkungsweise der Freilaufkupplung angedeutet, wobei der Pfeil die relative Drehung der jeweils treibenden Kupplung gegenüber der zurückbleibenden Welle andeutet.The impeller a of the turbine and the two stages 6 and. c of the fan have a common shaft e. The third blower stage d is also driven by the shaft e of the turbo blower when there is sufficient exhaust gas energy with the overrunning clutch according to the invention being blocked. In contrast, when the exhaust gas energy is low and especially when the engine is started, the overrunning clutch j is released and the fan stage d is driven by the machine shaft k via the gearwheels h, j while the other freewheel g is blocked. The mode of operation of the overrunning clutch is indicated in a cross section, the arrow indicating the relative rotation of the respective driving clutch with respect to the remaining shaft.
Die Anzahl der mit der Turbine fest verbundenen und der beim Anlassen von der Maschinenwelle angetriebenen Gebläsestufen kann nach Bedarf von der des Ausführungsbeispiels abweichen.The number of those firmly attached to the turbine and those when starting The fan stages driven by the machine shaft can be changed from that of the des Embodiment differ.
