Abstract
Description
Bessere IErmeausnutzung in herkömmlichen Wärme-Better heat utilization in conventional heat
kraftmaschinen durch Einspritzung einer Verdampfungsflüßigkeit,z.B. Wasser, nach erfolgter Verbrennung (Explosion), im Zylinder.engines by injecting an evaporative liquid, e.g. After combustion (explosion), water in the cylinder.
Die Erfindung betrifft Verbrennungskraftmaschinen,wo die Verbrennung des Kraftstoffes unmittelbar im Zylinder erfolgt.The invention relates to internal combustion engines where combustion of the fuel takes place directly in the cylinder.
An Iland einer bekannten Darstellung des Arbeitsvorganges bei Vergaser-Viertaktmotoren wird bei Takt I das Kraftstoff-Luftgemisch angesaugt und bei Takt II verdichtet.On Iland a well-known representation of the work process in carburettor four-stroke engines the fuel-air mixture is sucked in at cycle I and compressed at cycle II.
Bei Takt III erfolgt die Ziindung,normalerweise kurz. vor dem Totpunkt.At bar III the ignition takes place, usually briefly. before dead center.
Das Ktaftstoff-Luftgemisch verbrennt explosionsartig und entwickelt Temperaturen von über 2000 °C.Die Explosion bewirkt tin Druckanstieg im Verbrennungsraum der, wie bei Takt 1V dargestellt,in Arbeit umgewandelt wird..The fuel-air mixture burns explosively and develops Temperatures of over 2000 ° C. The explosion causes the pressure in the combustion chamber to rise which, as shown at 1V, is converted into work.
Durch die Kolbenbewegung sich der Druck schnell ab, trotzdem treten die Verbrennungsgase mit Temperaturen von mehr als 5000C in den Auspuff ein.Diese Energie geht und auch die mit der Kühlung abgeführten Wärmemenge, der Arbeitsleistung aller nicht stationeren Verbrennungskraftmaschinen verlohren.By the piston movement The pressure drops quickly, but the combustion gases still enter the exhaust with temperatures of more than 5000C. This energy is lost and the amount of heat dissipated with the cooling is lost to the work performance of all non-stationary internal combustion engines.
Erfindungsgemäß soll nwunehrdas Kraftstoff-Luftgemisch z.B.According to the invention, the fuel-air mixture should e.g.
weniger Fett zur Explosion gebracht werden.less fat will be made to explode.
Ebenso erfindungsgemäß soll nun nach erfolgter Zündung (Explosion)Arbeitshub
IV dadurch unterstützt werden,daß eine zur Verdampfung
Durch gezielte Mengeneinspritzung von Verdampfungsflüßigkeit nach erfolgter Zündung im ZylindeHwird die Druckanstiegsphase auch in den größer werdenden Raum hinein verlängert und dadurch der Wirkungsgrad der Wärme besser genutzt. Bei gleicher Leistung kann deshalb der Kolben kleiner bei gleichem Hubweg gehalten werden. Targeted injection of evaporating liquid in the cylinder after ignition has taken place, the pressure increase phase is also extended into the larger space and the efficiency of the heat is better used. With the same performance, the piston can therefore be kept smaller with the same stroke.
