Description
Luftverdichtende, selbstzündende Brennkraftmaschine Die Erfindung betrifft eine luftverdichtende, selbstzündende Brennkraftmaschine, insbesondere einen schnell laufenden Dieselmotor; mit rotationskörperähnlichem Verbrennungsraum, bei dem der Kraftstoff als dünner Film auf die Wandung des Brennraumes aufgebracht und zugleich der einströmenden Luft eine solche Drehbewegung erteilt wird, daß hierdurch der Kraftstoff in Dampfform von der Wandung allmählich abgelöst, vermischt und verbrannt wird.Air-compressing, self-igniting internal combustion engine The invention relates to an air-compressing, self-igniting internal combustion engine, in particular a fast running diesel engine; with a combustion chamber similar to a rotating body, in which the fuel is applied as a thin film to the wall of the combustion chamber and at the same time the inflowing air is given such a rotary motion that it thereby the fuel in vapor form gradually detached from the wall, mixed and burned will.
Zweck der Erfindung ist eine weitere Verbesserung der Gemischbildung durch besondere Ausbildung der Brennraumwand.The purpose of the invention is to further improve the mixture formation due to the special design of the combustion chamber wall.
Bei Brennkraftmaschinen vorstehender Bauart und Betriebsweise wird der Kraftstoff filmartig auf die Brennraumwand aufgetragen und durch eine in geeigneter Weise zugeordnete Luftdrehung von höchstmöglicher kinetischer Drehenergie in Dampfform von der Brennraumwand abgelöst, mit der Luft vermischt und verbrannt. Der flüssige Kraftstoff wird dabei, wie es für diese Art Kraftstoffeinspritzung erstmals in der deutschen Patentschrift 865 683 angegeben wurde, bewußt der unmittelbaren Vermischung mit der Verbrennungsluft entzogen, um alle jene Vorreaktionen zu vermeiden, welche einen vorzeitigen chemischen Zerfall der Kraftstoffmoleküle zur Folge haben und dadurch einen zu raschen Reaktionsablauf bei der Verbrennung mit den dabei zu erwartenden Mängeln, wie Klopfgeräusche, hoher Kraftstoffverbrauch und starke Abgastrübung, bedingen.In internal combustion engines of the above design and mode of operation the fuel is applied in a film-like manner to the combustion chamber wall and a suitable one Wise assigned air rotation of the highest possible kinetic rotation energy in vapor form detached from the combustion chamber wall, mixed with the air and burned. The liquid one Fuel is used as it was for this type of fuel injection for the first time in the German Patent 865 683 was given, conscious of the immediate mixing withdrawn with the combustion air in order to avoid all those preliminary reactions, which cause premature chemical breakdown of the fuel molecules and as a result, the reaction process is too rapid during the combustion with the expected ones Defects such as knocking noises, high fuel consumption and strong exhaust gas opacity, condition.
Obgleich durch die wandverteilte Auftragung des Kraftstoffes auf eine glatte Brennraumwand bereits eine weitgehende Beseitigung der vorstehenden Mängel erreicht wurde, so hat sich doch gezeigt, daß man bei den nach dem obigen Prinzip arbeitenden Brennkraftmaschinen den Verdampfungsprozeß auf der Brennraumwand noch weiter im Sinne einer Verbesserung der Gemischbildung steigern kann, wenn die vom Kraftstoff benetzte Brennraumwandungsöberfläche hinsichtlich ihrer quantitativen Aufnahmefähigkeit potenziert wird, ohne daß man dabei gezwungen ist, die geometrische Flächenausbreitung der Brennraumwand zu vergrößern.Although the wall-distributed application of the fuel to a smooth combustion chamber wall already largely eliminates the above deficiencies has been achieved, it has been shown that one works according to the above principle working internal combustion engines still the evaporation process on the combustion chamber wall can further increase in the sense of improving the mixture formation if the from Fuel-wetted combustion chamber wall surface in terms of its quantitative Absorption capacity is increased without being forced to use the geometric To enlarge the area of the combustion chamber wall.
Dies wird erfindungsgemäß dadurch erreicht, daß der Brennraum in an sich bekannter Weise eine in das umgebende harte Material des Brennraumträge.rs (Kolben, Zylinderkopf) fest eingebettete poröse Wandauskleidung aufweist, deren Porosität (Korngröße, Korndichte) und Dicke so bemessen sind, daß sie mindestens einen Teil des beim Einspritzvorgang filmartig auf die poröse Wandung aufgetragenen Kraftstoffes unter der Einwirkung des Kompressionsdruckes schwammartig in sich aufnimmt und im Zuge der Verdampfung wieder abgibt. Die poröse Wandauskleidung kann dabei beispielsweise aus einem Sinterstoff bestehen und weist zweckmäßig eine Porosität in der Größenordnung von etwa 60°/o auf.This is achieved according to the invention in that the combustion chamber is in on As is known, a hard material surrounding the combustion chamber is carried out (Piston, cylinder head) has firmly embedded porous wall lining, whose Porosity (grain size, grain density) and thickness are such that they are at least a part of the film-like applied to the porous wall during the injection process Absorbs fuel like a sponge under the action of the compression pressure and gives off again in the course of evaporation. The porous wall lining can thereby consist for example of a sintered material and expediently has a porosity of the order of about 60%.
Durch die erfindungsgemäße Auskleidung des Brennraumes mit einer porösen Wandung wird erreicht, daß der Verdampfungsprozeß des Kraftstoffes gleichmäßiger als bei glatter oder materialharter Brennraumwandung erfolgt, so daß keinerlei Druckspitzen im Ablauf der Verbrennung auftreten und das Diagramm des Verbrennungsablaufes sich einer Gleichdruckverbrennung weitgehend nähert.The inventive lining of the combustion chamber with a porous Wall is achieved that the evaporation process of the fuel more evenly than occurs with a smooth or material-hard combustion chamber wall, so that no pressure peaks whatsoever occur in the course of the combustion and the diagram of the combustion process itself largely approaches a constant pressure combustion.
Poröse Auskleidungen des Verbrennungsraumes von Brennkraftmaschinen sind zwar an sich schon vorgeschlagen worden, jedoch nicht in der besonderen Aufgabenstellung und Ausbildung gemäß der Erfindung. Bei einer bekannten Einrichtung dieser Art ist die poröse Wandauskleidung mit besonderen, nach außen führenden Kanälen versehen, die an ein Druckflüssigkeitssystem angeschlossen sind. Es wird dabei Flüssigkeit unter Druck in die poröse Masse eingeführt, die nach innen verdampfen und an der Innenwand des Brennraumes eine wärmeisolierende Dampfhaut bilden soll. Der Zweck dieser Anordnung ist Wärmeisolation. Bei solcher Anordnung wäre es unmöglich, daß irgendwelcher filmartig an der Wand verteilter Kraftstoff in die unter äußerem Flüssigkeitsdruck stehende Brennraumwandungsfläche eindringt; vermutlich würde noch nicht einmal eine Kraftstoffilmbildung auf der Brennraumwand gelingen. Der Kraftstoff würde vielmehr sich mit dem allseits eindringenden Wasserdampf in unerwünschter Weise vermischen und einen unkontrollierbaren Ablauf der Verbrennungsreaktion herbeiführen.Porous linings of the combustion chamber of internal combustion engines have already been proposed per se, but not in the special task definition and training according to the invention. In a known device of this type the porous wall lining is provided with special channels leading to the outside, which are connected to a hydraulic fluid system. It becomes liquid introduced under pressure into the porous mass, which evaporate inwards and at the Inner wall of the combustion chamber should form a heat-insulating vapor skin. The purpose this arrangement is thermal insulation. With such an arrangement it would be impossible that any fuel spread like a film on the wall into the under external fluid pressure standing combustion chamber wall surface penetrates; probably not even one Successful fuel film formation on the combustion chamber wall. Rather, the fuel would mix in an undesirable way with the water vapor penetrating from all sides and cause an uncontrollable course of the combustion reaction.
Nach einem anderen bekannten Vorschlag wird bei gemischverdichtenden Brennkraftinaschinen (Gaskraftmaschinen ) zur Beschleunigung des Verbrennungsablaufes die Wandung des Verbrennungsraumes mit katalytisch wirkenden Stoffen, z. B. Platinmetall, ausgekleidet, die in poröser feuerfester Masse verwendet werden. Derartige Katalysatoren erfüllen jedoch nicht die Voraussetzungen zur Lösung der Aufgabenstellung der Erfindung, da sie als ausgesprochene Reaktionsbeschleuniger in der dem älteren Vorschlag entsprechenden Anwendungsweise bei einer luftverdichtenden, selbstzündenden Brennkraftmaschine gemäß der Erfindung nicht brauchbar sind.According to another known proposal, in the case of mixture compressing Internal combustion engines (gas engines ) to speed up the Combustion process the wall of the combustion chamber with catalytically active Substances, e.g. B. platinum metal, lined, used in porous refractory mass will. However, such catalysts do not meet the requirements for solution the object of the invention, since it is a pronounced reaction accelerator in the application method corresponding to the older proposal for an air-compressing, self-igniting internal combustion engine according to the invention are not useful.
In der Zeichnung ist die Erfindung an einem bevorzugten Ausführungsbeispiel dargestellt. Hierbei zeigt Fig. 1 einen axialen Längsschnitt durch den Kolben einer Brennkraftmaschine mit darin angeordnetem Brennraum und erfindungsgemäßer Ausbildung der Brennraumwandung (Zylinder und Zylinderkopf der Brennkraftmaschine sind nur angedeutet) , Fig. 2 einen Grundriß des Kolbens in Fig. 1 unter Darstellung von Teilen im Schnitt und in Perspektive. Der bei der Brennkraftmaschine 1 vorgesehene Kolben 2 besitzt einen im Kolbenboden angeordneten rotationskörperähnlichen Brennraum 3, welcher im vorliegenden Fall die Form eines Rotationsellipsoides aufweist, wobei die Brennraumöffnung durch einen halsartigen übertrittskanal 4 nach dem Hauptverbrennungsraum 5 gebildet ist. An der Brennraumöffnung 4 ist eine taschenartige Ausbuchtung 6 ausgespart, die in der oberen Totpunktlage des Kolbens die Düsenmündung einer Einspritzdüse 7 aufnimmt, aus der der Kraftstoff mittels der Kraftstoffstrahlen 8, 9 in filmartiger Verteilung auf die Brennraumwand 10 aufgebracht wird. Der Auftragung des Kraftstoffes auf die Brennraumwand ist in bekannter Weise die durch den_ Pfeil 11 (Fig.2) angedeutete Luftdrehung zugeordet, wodurch der Kraftstoff allmählich in dampfförmigem Zustand von der benetzten Brennraumwandungsoberfläche abgelöst wird.In the drawing, the invention is based on a preferred embodiment shown. Here, Fig. 1 shows an axial longitudinal section through the piston of a Internal combustion engine with a combustion chamber arranged therein and a design according to the invention the combustion chamber wall (cylinder and cylinder head of the internal combustion engine are only indicated), Fig. 2 is a plan view of the piston in Fig. 1 showing Share in section and in perspective. The one provided in the internal combustion engine 1 Piston 2 has a combustion chamber similar to a rotational body arranged in the piston crown 3, which in the present case has the shape of an ellipsoid of revolution, wherein the combustion chamber opening through a neck-like transfer channel 4 after the main combustion chamber 5 is formed. A pocket-like bulge 6 is recessed at the combustion chamber opening 4, the nozzle orifice of an injection nozzle in the top dead center position of the piston 7 receives, from which the fuel by means of the fuel jets 8, 9 in film-like Distribution is applied to the combustion chamber wall 10. The application of the fuel on the combustion chamber wall is indicated in a known manner by the arrow 11 (FIG. 2) Associated with air rotation, causing the fuel to gradually turn into a vaporous state is detached from the wetted combustion chamber wall surface.
Erfindungsgemäß wird die Brennraumwand 10 von einer porösen Materialschicht 12 gebildet, die beispielsweise aus Sinterstoff besteht und die ihrerseits in das sie umgebende harte und dichte Material des eigentlichen Brennraumträgers, d. h. hier des Kolbens 2, eingebettet ist. Die Dicke d der porösen Schicht 12 muß mindestens so groß sein und eine inakroskopische Korngröße von solcher Beschaffenheit aufweisen, daß der auf die Wand 10 aufgespritzte Kraftstoff unter Einwirkung des Verdichtungsdruckes teilweise in die poröse Schicht 12 eindringen und darin bis zur Endphase der Verdampfung gespeichert werden kann. Nach einem weiteren Merkmal der Erfindung ist für die die Brennraumwand bildende Sintermasse eine Porosität von etwa 60% vorgesehen, womit der gewünschte Erfolg erreicht wird.According to the invention, the combustion chamber wall 10 is made of a porous material layer 12 formed, which consists for example of sintered material and which in turn is in the the surrounding hard and dense material of the actual combustion chamber support, d. H. here the piston 2 is embedded. The thickness d of the porous layer 12 must be at least be so large and have an inacroscopic grain size of such a nature, that the fuel sprayed onto the wall 10 under the action of the compression pressure partially penetrate into the porous layer 12 and therein until the end phase of evaporation can be saved. According to a further feature of the invention is for the Sintered mass forming the combustion chamber wall has a porosity of about 60%, which means the desired success is achieved.
Die Wirkungsweise der Maschine ist folgende: Wie üblich wird der Kraftstoff beim Verdichtungshub jeweils vor Erreichen des oberen Totpunktes ein gespritzt. Wenn nun auf die durch die poröse Schicht 12 gebildete Brennraumwandung 10 der Kraftstoff in Form eines dünnen Films aufgebracht wird, dann wird unter Einfluß des gegen Ende der Verdichtung weiterhin zunehmenden Druckes im Brennraum dieser filmartig verteilte Kraftstoff teilweise in den Sinterstoff der Brennraumauskleidung 12 verdrängt. Bei Einsetzen der Zündung wird zunächst weiter ein Teil des Kraftstoffes noch in den Sinterstoff eindringen, dann aber nach Ablösung der obersten Benetzungsschicht wieder aus den Poren der Wandung austreten und dank dieser vergrößerten Oberflächenwirkung also unter günstigeren Bedingungen verdampfen, als dies bei glatter Wandungsfläche der Fall wäre. Der Vorteil im Ablauf de r Gesamtverbrennung besteht in der schon erwähnten Annäherung des Druckverlaufes im Brennraum an ein Gleichdruckdiagramm.The way the machine works is as follows: As usual, the fuel is injected on the compression stroke before top dead center is reached. If the fuel is now applied in the form of a thin film to the combustion chamber wall 10 formed by the porous layer 12, this film-like fuel is partially displaced into the sintered material of the combustion chamber lining 12 under the influence of the pressure in the combustion chamber, which continues to increase towards the end of compression. When the ignition starts, some of the fuel will initially continue to penetrate the sintered material, but then exit the pores of the wall again after the top wetting layer has been detached and, thanks to this increased surface effect, evaporate under more favorable conditions than would be the case with a smooth wall surface . The advantage in the course of the overall combustion consists in the already mentioned approximation of the pressure curve in the combustion chamber to a constant pressure diagram.
Die Erfindung ist nicht auf die hierin gezeigte Brennraumanordnung oder Brennraumform beschränkt, sondern anwendbar auf alle Brennräume - gleichgültig, ob im Kolben oder im Zylinderkopf liegend -, bei denen eine Gemischbildung unter filmartiger Wandverteilung des Kraftstoffes möglich ist.The invention is not limited to the combustion chamber arrangement shown herein or combustion chamber shape, but applicable to all combustion chambers - regardless of whether in the piston or in the cylinder head - in which a mixture formation under film-like wall distribution of the fuel is possible.
