KAISERLICHESIMPERIAL
PATENTAMTPATENT OFFICE
Der Grundgedanke des Patentes 288052 ist, die Kühlwasserzufuhr in zwei zeitlich getrennten Augenblicken erfolgen zu lassen. Bisher ist es als zweckmäßig erkannt worden, den einen Teil des Kühlwassers vor der Brennstoffzuführung und den anderen derselben nach der Brennstoffzuführung zuzuführen.The basic idea of the patent 288052 is the cooling water supply in two temporally separated To let moments happen. So far, it has been recognized as useful, some of the cooling water before the fuel supply and to supply the others thereof after the fuel supply.
Es hat sich nun herausgestellt, daß diese Art der Wasserzuführung je nach ■ der Höhe der angewandten Vorkompression und je nach der mehr oder weniger feinen Zerstäubung des Brennstoffes und vor allem des Wassers vorteilhaft dahin geändert werden kann, daß die Brennstoffzuführung und eine der Wasserzuführungen sich ganz oder teilweise decken. In jedem Falle bleibt aber der Grundgedanke der Erfindung bestehen, daß nämlich die Hauptwasserzuführungen in zeitlich getrennten Augenblicken erfolgen.It has now been found that this type of water supply depends on the height the pre-compression used and depending on the more or less fine atomization of the Fuel and especially the water can be advantageously changed so that the Fuel feed and one of the water feeds completely or partially coincide. In any case, the basic idea of the invention remains, namely that the Main water supplies take place at separate moments.
Fall I. Je höhere Vorkompressionen zur Anwendung gelangen, desto später kann die Brennstoffzuführung erfolgen, da bei höherer Kompression in dem hierdurch entstehenden kleineren Kompressionsraume eine schnellere und intensivere Mischung der Brennstoffe und der vorkomprimierten Luft vor sich geht.Case I. The higher the pre-compressions are used, the later the Fuel supply takes place, since with higher compression in the resultant smaller compression chambers a faster and more intense mixture of fuels and of the pre-compressed air going on.
Erfolgt nun zwecks noch besserer Vermeidung von Frühzündungen die Brennstoffzuführung kurz vor dem Totpunkte, so kann es der Fall sein, daß zur zweiten Wassereinführung bzw. zur Entwicklung des Dampfes aus derselben nicht mehr genügend Zeit bleibt, um noch rechtzeitig das Wasser nach Beendigung der Brennstoffzuführung einzuführen und zur beabsichtigten Wirkung zu bringen. In diesem Falle kann die zweite Wasserzuführung auch mit erheblichem Erfolge ganz oder teilweise zusammen mit der Brennstoffeinführung vorgenommen werden.The fuel is now supplied for the purpose of even better avoidance of pre-ignition shortly before the dead center, it may be the case that the second water introduction or there is no longer enough time to develop the steam from the same, so that the water is still in time after the end the fuel supply and bring it to the intended effect. In this case, the second water supply also with considerable success in whole or in part together with the introduction of fuel be made.
Fall II. Je größer. die Zerstäubung der Brennstoffe und vor allem des Wassers beim Eintritt in die Glühhaube ist, desto schneller und intensiver ist die Wirkung des letzteren. Die Kühlung der Glühhaube geschieht so schnell, daß die Zersetzung des Brennstoffes auch dann vermieden wird, wenn die Brennstoffzuführung und die erste Wasserzuführung ganz oder teilweise zu gleicher Zeit erfolgen.Case II. The bigger. the atomization of the The faster the fuel, and especially the water, enters the glow hood and the action of the latter is more intense. The annealing hood is cooled in this way quickly that the decomposition of the fuel is avoided even when the fuel supply and the first water supply takes place wholly or partially at the same time.
In beiden Fällen wird aber das Wasser in zwei getrennten Augenblicken zugeführt; im ersten Falle erfolgt die erste Wasserzuführung vor der Brennstoffzuführung und die zweite Wasserzuführung ganz oder teilweise mit der Brennstoffzuführung; im zweiten Falle dagegen erfolgt die erste Wasserzuführung ganz oder teilweise mit der Brennstoffzuführung zusammen, und die zweite nach der Brennstoffzuführung.In both cases, however, the water is supplied in two separate moments; in the first case, the first water supply takes place before the fuel supply and the second water supply wholly or partially with the fuel supply; in the second case on the other hand, the first water supply takes place wholly or partially with the fuel supply together, and the second after the fuel supply.
Wie schon in der Patentschrift 288052 hervorgehoben ist, kann die Wasserzuführung auch so geregelt werden, daß zwischen der ersten und zweiten Wasserzuführung dieselbe nicht ganz aufgehoben wird, sondern nur langsamer erfolgt. Es kann endlich auch dieAs already pointed out in patent specification 288052, the water supply can also be regulated so that the same between the first and second water supply is not completely canceled, but only occurs more slowly. It can finally do that too
Wasserzuführung in drei oder mehr Stufen erfolgenj beispielsweise so, daß zwischen der ersten und zweiten Wassereinführung die Brennstoffzuführung in Verbindung mit Wassereinspritzung erfolgt.Water supply in three or more stages take place, for example, so that between the first and second water introduction the fuel supply in connection with water injection he follows.
