Description

Explosionsmotor. Um bei verschiedenen Füllungsgraden der Explosionsmotoren den günstigsten Wirkungsgrad zu erzielen, ist es wünschenswert, daß der Endkompressionsdruck stets die zulässige Grenze erreicht. Diese Grenze wird durch die Temperatur bestimmt, , bei welcher Selbstzündung des Gemisches eintritt und die bei den bekannten Brennstoffen etwa bei 5 Atmosphären liegt.Explosion engine. To with different degrees of filling of the explosion engines To achieve the best efficiency, it is desirable that the final compression pressure always reached the permissible limit. This limit is determined by the temperature, , at which self-ignition of the mixture occurs and that of the known fuels is about 5 atmospheres.

Diese Arbeitsbedingung ist bei gleich bleibender Zusammensetzung des Gemisches unerfüllbar, weil der Endkompressionsdruck und die Endtemperatur vom Füllungsgrade abhängig sind. Ist beispielsweise der Motor derart konstruiert, daß der Enddruck von 5 Atmosphären bei voller Füllung erreicht wird, so beträgt bei einer Füllung von 5o Prozent der Enddruck etwa z,5 Atmosphären, während bei einem Motor, der schon bei halber Füllung einen Endkompressionsdruckvon 5 Atmosphären ergibt, bei voller Füllung man auf einen Endkompressionsdruck von xo Atmosphären gelangt. Ein solcher Motor arbeitet mit großer Vorzündung, da die zugehörige Endtemperatur weit über der Selbstzündungsgrenze liegt.This working condition is the same if the composition of the Mixture cannot be fulfilled because the final compression pressure and the final temperature depend on the degree of filling are dependent. If, for example, the engine is designed in such a way that the ultimate pressure of 5 atmospheres is reached with a full filling, then amounts to with one filling from 5o percent of the final pressure to about z.5 atmospheres, while with an engine that is already at half full gives a final compression pressure of 5 atmospheres, at full Filling one reaches a final compression pressure of xo atmospheres. Such a The engine works with a large pre-ignition because the associated final temperature is far above the auto-ignition limit is.

Um nun bei -allen Füllungsgraden die Temperatur unterhalb der Selbstentzündung--grenze zu halten, wird der Erfindung gemäß mit Benutzung des zur Herabsetzung der Kompressionstemperatur bekannten Mittels der Wassereinspritzung, der Kompressionsraum des Motors so gering bemessen, daß schon etwa bei ein Viertel Füllung die Endkompression von g Atmosphären erreicht wird und bei höheren Füllungsgraden wird in die Zylinder eine mit der Füllung zunehmende Wassermenge eingespritzt.In order to keep the temperature below the auto-ignition limit at all filling levels to keep, is according to the invention using the to lower the compression temperature known means of water injection, the compression space of the engine is so small dimensioned that the final compression of g atmospheres at about a quarter of the filling is reached and with higher degrees of filling is in the cylinder with the filling increasing amount of water injected.

Um diese 'nWassermengen dem Füllungsgrade anzupassen, wird die Einrichtung; welche der Füllungsgrad regelt mit jener, durch welche die Menge des eingespritzten Wassers geregelt wird, derart zwangläufig verbunden, daß bei geringstem Füllungsgrade die Wassereinspritzung Null ist und bei dem größten Füllungsgrade die Höchstgrenze erreicht.In order to adapt these 'n water quantities to the degree of filling, the device is; which regulates the degree of filling with that through which the amount of the injected Water is regulated, so inevitably connected that with the lowest degree of filling the water injection is zero and the maximum limit at the highest degree of filling achieved.

Man wird die Wasserdüse möglichst nahe an das Ansaugeventil verlegen und die Periode der Wasserzuführung mit jener der Ansaugung zusammenfallen lassen, so daß das Wasser infolge des im Zylinderraum herrschenden Unterdrucks rasch und wirksam verdampft.The water nozzle will be relocated as close as possible to the suction valve and make the period of water supply coincide with that of suction, so that the water quickly and as a result of the negative pressure prevailing in the cylinder chamber effectively vaporizes.
