Description
Kreiskolbenmotor mit beliebig konstruier baren VerbrennungsräumenRotary piston engine with any design combustible rooms
Die Erfindung betrifft einen Verbrennungsmotor, der ein Benzin-Luft-Gemisch entzündet, ver brennt und dabei Arbeit leistet.The invention relates to an internal combustion engine, which ignites a gasoline-air mixture, ver burns and does work.
Der Verbrennungsmotor gehört zur Gattung der Kreiskolbenmotoren.The internal combustion engine belongs to the genus Rotary piston engines.
Es ist bekannt, daß der Kreiskolbenmotor NSU- Wankel unbestritten viele Vorteile bietet, wie zum Beispiel: Einfachheit (keine Ventile), hohe Leistungskonzentration auf kleinem Raum, geräuscharmer und nahezu vibrationsfreier Lauf. It is known that the NSU Undoubtedly, Wankel offers many advantages, such as: simplicity (no valves), high power concentration in a small space, low-noise and almost vibration-free running.
Der "Wankelmotor" fällt unangenehm auf durch seinen hohen spezifischen Kraftstoffverbrauch, der auf den ungünstigen, langen und sichel förmigen Verbrennungsraum ("Mövenschwingen") zurückzuführen ist. Außerdem ist die Zündkerze dauernd wärmebelastet und hat eine entsprechend kürzere Lebensdauer.The "Wankel engine" falls through unpleasantly its high specific fuel consumption, the one on the awkward, long and sickle shaped combustion chamber ("gull swing") is due. In addition, the spark plug constantly exposed to heat and has a corresponding shorter lifespan.
Das Ziel der Erfindung ist, den Verbrauch zu senken und eine längere Lebensdauer der Zündkerze zu erreichen, aber trotzdem keinen Vorteil des "Wankelmotors" zu streichen.The aim of the invention is consumption lower and longer life of the To reach the spark plug, but still none Eliminate the advantage of the "Wankel engine".
Zur Lösung der Aufgabe mußte ein neuer Kreis kolbenmotor konstruiert werden. Eine verkürzte zweibogige Epizykloide ("Trochoide") kreist in einem kleeblattähnlichen Gehäuse. Der Ver brennungsraum ist in frei wählbarer Form an frei wählbarer Stelle plaziert (in meinem Ausführungsbeispiel wurde ein verbrennungs günstiger, halbkugeliger Verbrennungsraum gewählt). Dadurch, daß in jedem Verbrennungs raum eine eigene Zündkerze plaziert ist, und sie nicht dauernd der Wärmebelastung ausge setzt ist, hat sie eine über dreifache Lebens dauer gegenüber einer "Wankelzündkerze" (sie wird ja auch nur 1/3mal so oft beansprucht).To solve the problem, a new circular piston engine had to be constructed. A shortened double-arched epicycloid ("trochoid") circles in a shamrock-like housing. The combustion chamber is placed in a freely selectable position at a freely selectable position (in my embodiment, a combustion-favorable, hemispherical combustion chamber was chosen). Because space in each combustion a separate spark plug is in place, and they are not permanently connected to the heat load being set is, it has a three-fold service life compared with a "Wankelzündkerze" (it is also only 1/3 times as often claimed).
Die mit der Erfindung erzielbaren Vorteile bestehen darin, daß der Kraftstoffverbrauch eines Kreiskolbenmotors wesentlich gesenkt werden könnte. Außerdem wird eine über dreimal so lange Lebensdauer der einzelnen Zündkerzen erwartet (allerdings müssen dann immer drei Zündkerzen auf einmal ausgetauscht werden). Die Erfindung eignet sich voraussichtlich auch für Dieselkraftstoffbetrieb, bei ent sprechender Erhöhung der Verdichtung. Denk bar wäre auch ein Drehkolbenmotor, bei dem sich Rotor und Gehäuse jeweils um ihre Mittel punktachse drehen. Die Folge wäre ein turbinen artiger, vibrationsfreier Lauf, der durch die voll auswuchtbare reine Drehbewegung zustande käme.The advantages achievable with the invention are that fuel consumption a rotary piston engine significantly reduced could be. It also gets over three times so long life of the individual spark plugs expected (but then always three Spark plugs can be replaced at once). The invention is likely to be suitable also for diesel fuel operation, at ent speaking increase in compaction. Think bar would also be a rotary piston engine in which rotor and housing each around their means rotate the point axis. The result would be a turbine well-behaved, vibration-free run, which by the fully balanced, pure rotary movement would come.
Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt und wird im fol genden näher beschrieben. Es zeigtAn embodiment of the invention is in the drawings and is shown in fol described in more detail. It shows

Es folgt die Erläuterung der Erfindung anhand der Zeichnungen nach Aufbau und Wirkungsweise der dargestellten Erfindung. The following is an explanation of the invention based on the drawings according to structure and mode of operation of the illustrated invention.
Der große Kreis stellt ein innenverzahntes Zahnrad dar, das oberhalb des Rotors fest am Gehäuse befestigt ist.The large circle represents an internal gear Gear wheel that is fixed above the rotor is attached to the housing.
Der kleine Kreis stellt ein außenverzahntes Zahnrad dar, das über den Rotor hinausragt (bis zum innenverzahnten Zahnrad) und fest am Rotor befestigt ist.The small circle represents an external gear Gear wheel that protrudes beyond the rotor (up to the internal gear) and firmly is attached to the rotor.
Das Verhältnis von großem zu kleinem Zahnrad muß 3 : 2 betragen.The ratio of large to small gear must be 3: 2.
Die Zahlen in den einzelnen Kammern geben die Zahl des jeweiligen Verbrennungstaktes an:The numbers in the individual chambers indicate the Number of combustion cycles to:
- 1. Takt - ansaugen,1st stroke - suck in,
- 2. Takt - verdichten,2nd stroke - compress,
- 3. Takt - arbeiten,3rd bar - work,
- 4. Takt - ausschieben.4th cycle - slide out.
Zwischen 2. und 3. Takt wird das Gemisch ge zündet (evtl. geringe Vorzündung).Between the 2nd and 3rd cycle, the mixture is ge ignites (possibly slight pre-ignition).
Der Einlaß (durch EIN gekennzeichnet) ist nach oben (zum Betrachter hin) an einen dreieckähnlichen Ansaugkanal angeschlossen. Der Auslaß (durch AUS gekennzeichnet) ist nach unten (vom Betrachter weg) an einen ebenfalls dreieckähnlichen Auslaßkanal ange schlossen.The inlet is (marked by ON) upwards (towards the viewer) to one triangular-like intake duct connected. The outlet (indicated by OFF) is down (away from the viewer) to one also triangle-like outlet channel closed.
An den 3 Ecken, an denen der Rotor ständig anliegt, muß eine Dichtleiste (bekannt vom "Wankelmotor" her) eingesetzt werden. Ebenso müssen auf der Innenseite des Gehäuses Dicht streifen verlegt werden (rote Kennzeichnung). Die Schraffierung in Fig. 5 soll eine Ver tiefung darstellen, die als Auslaßkanal dient. Dieser wird an beliebiger Stelle "angezapft", um die Abgase über einen Schalldämpfer ins Freie zu entlassen. Von derselben Form ist auch der Einlaßkanal auf der oberen Seite des Gehäuses, über den das Gasgemisch vom Vergaser in den Einlaß, und anschließend in die einzelnen Kammern strömt. Denkbar wäre auch die Möglichkeit des Direkteinspritzens, wobei der Kraftstoff direkt in den Verbrennungs raum eingespritzt und anschließend entzündet würde.A sealing strip (known from the "Wankel engine") must be used at the 3 corners where the rotor is always in contact. Sealing strips must also be laid on the inside of the housing (red marking). The hatching in Fig. 5 is intended to represent a recess that serves as an outlet channel. This is "tapped" at any point in order to discharge the exhaust gases into the open via a silencer. The inlet duct on the upper side of the housing, through which the gas mixture flows from the carburetor into the inlet and then into the individual chambers, is of the same shape. The possibility of direct injection would also be conceivable, with the fuel being injected directly into the combustion chamber and then ignited.
Der Mittelpunkt des kleinen Zahnrads beschreibt einen Kreis innerhalb des großen Zahnrads. An dieser Stelle (Mittelpunkt des kleinen Zahn rads) wird die Leistung über eine Kurbelwelle abgenommen.The center of the small gear describes a circle inside the big gear. At this point (center of the small tooth rads) is the power via a crankshaft decreased.
