Description

  

  Explosionsmotor.    Bei den bisher üblichen     Explosionsmotoren     ist die Grösse des     Kompressionsraumes    derart  bemessen, dass bei Höchstleistung des Motors  eine Selbstzündung noch nicht eintritt, weil  sonst die Zündung zu früh stattfindet und  hierdurch die Leistung des Motors erheblich  sinkt. Unter Umständen ist es aber wünschens  wert, einem solchem Motor eine spezifisch  grössere Leistung zu geben, als er er unter  normalen Arbeitsverhältnissen und bei normaler  Bauart abzugeben imstande ist. Dieses kann  beispielsweise durch Einpressen eines grösseren  Luftgewichtes als das durch die Saugwirkung  des Kolbens     einführbare    erreicht werden. Die  Zuführung eines solchen grösseren Luftge  wichtes erfolgt dann beispielsweise mit Hilfe  eines Gebläses.  



  Wird in dieser Weise der Motor künst  lich mit einem grösseren Ladungsgewichte  beschickt, so treten in den Zylindern entspre  chend höhere     Kompressionsdrücke.    und Tem  peraturen auf, die die oben erwähnten zu  frühen und darum schädlichen Selbstzündungen  herbeiführen.

   Gemäss der Erfindung soll nun    dieser     \'acliteil    dadurch verhütet werden, dass  der     Kompressionsraum    der Zylinder     iin    Ver  hältnis zum     Kolbenhubvolumen    so gross be  messen ist, dass der Kompressionsdruck die  Höhe, des Selbstzündung     sdruckes    nicht vor  dem Augenblick erreicht, in welchem die  Zündung der Ladung die     Höchstleistung    be  wirkt.

   -Um einen solchen auch ohne künstliche  Zuführung der Ladung benützen zu können,  empfiehlt es sich, die Grösse des Kompressions  raumes veränderlich     zii    machen und ihn beim  Arbeiten des Motors ohne künstliche     Ladunts-          zuführung    so einzustellen, dass auch in diesem  Falle die Höhe des Kompressionsdruckes die  Höhe des     Selbstzündungsdruckes    nicht vor  dem Augenblick erreicht, in welchem die  Zündung der Ladung die Höchstleistung  bewirkt.  



       Auf    der     Zeichnung    ist ein     Ausführungs-          beipiel    des     Erfindungsgegenstandes    darge  stellt.  



  Durch ein mit dem Motor     cz    verbundenes  Gebläse b kann dem     Vergaser    c eine Luft  menge zugeführt werden, welche in bezug      auf das Gewicht der Luftmenge grösser ist,  als es der     Saugwirkung    des Kolbens entspricht.

    Diese Luft,     welche    im Vergaser     Brennstoff          ansangt,    tritt in den     Arbeitszylinder    d ein,  dessen Kompressionsraum     d'    grösser ist als  bei einem normalen Motor, und zwar ist  die Grösse des Kompressionsraumes im Ver  hältnis zum     Kolbenhubvolumen    so bemessen,  dass bei     Zuführundes'    grössten Ladungsge  wichtes mit     Hilfe'-'des    Gebläses der Kompres  sionsdruck     dleHöhe    des     Selbstzündungsdruckes     nicht vor dem Augenblick erreicht, der für die  Erzielung der Höchstleistung     massgebend    ist.



  Explosion engine. In the previously common explosion engines, the size of the compression chamber is dimensioned in such a way that auto-ignition does not yet occur when the engine is at its peak, because otherwise the ignition will take place too early and the engine's output will decrease considerably. Under certain circumstances, however, it is desirable to give such a motor a specifically greater power than it is capable of delivering under normal working conditions and with a normal design. This can be achieved, for example, by pressing in a greater weight of air than that which can be introduced by the suction effect of the piston. The supply of such a larger Luftge weight then takes place, for example, with the help of a fan.



  If the engine is loaded artificially with a larger load weight in this way, correspondingly higher compression pressures occur in the cylinders. and temperatures that cause the above-mentioned premature and therefore harmful auto-ignition.

   According to the invention, this part is to be prevented by measuring the compression space of the cylinder in relation to the piston stroke volume so large that the compression pressure does not reach the level of the compression ignition pressure before the moment when the charge is ignited causes maximum performance.

   In order to be able to use such a system without an artificial supply of cargo, it is advisable to change the size of the compression space and, when the engine is working without an artificial supply of cargo, to adjust it so that in this case too the level of the compression pressure is The self-ignition pressure is not reached before the moment when the ignition of the charge causes maximum power.



       The drawing shows an exemplary embodiment of the subject matter of the invention.



  By means of a fan b connected to the motor cz, an amount of air can be supplied to the carburetor c which, in relation to the weight of the amount of air, is greater than the suction effect of the piston.

    This air, which reaches the fuel in the carburetor, enters the working cylinder d, the compression chamber d 'of which is larger than that of a normal engine, and indeed the size of the compression chamber in relation to the piston stroke volume is so dimensioned that the greatest charge weight is achieved when the fuel is supplied With the help of '-' of the blower, the compression pressure dle height of the auto-ignition pressure is not reached before the moment that is decisive for achieving maximum performance.
