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.
