Description
Drehzahlbegrenzer für Brennkraftmaschinen Die Erfindung betrifft einen Drehzahlbegrenzer für Brennkraftmaschinen, insbesondere mit Füllungsregelung, bei dem die Gaszu-oder Gasabfuhr durch die Resonanz eines Schwingers in der Ansaug- oder Auspuffleitung bei einer bestimmten Drehzahl gestört oder unterbrochen wird.Speed limiter for internal combustion engines The invention relates to a Speed limiters for internal combustion engines, in particular with filling control, at the gas supply or gas discharge through the resonance of a vibrator in the intake or the exhaust line is disturbed or interrupted at a certain speed.
Es sind Drehzahlbegrenzer bekannt, bei denen der Schwinger aus einem vom Unterdruck der Saugleitung beaufschlagten federbelasteten Kolben besteht, der beim Erreichen der Drehzahlbegrenzung in Eigenschwingungen gerät und die GemischzufuhY mehr oder minder abdrosselt. Der Schwinger benötigt in diesem Falle zwei voneinander unabhängige Mittel, den als Abschlußorgan der Saugleitung dienenden massenbehafteten Kolben und die die Schwingungsfähigkeit des Kolbens bewirkende Feder, die beide aufeinander abzustimmen sind. Da der Kolben in einer Führung der Saugleitung gleitet, treten Reibungswiderstände von veränderlicher Größe auf, die das Ansprechen des schwingungsfähigen Systems in unabsehbarer Weise verzögern oder verhindern können.There are speed limiters known in which the oscillator from one there is a spring-loaded piston acted upon by the vacuum in the suction line, the when the speed limit is reached, the mixture starts to oscillate more or less throttled. In this case, the transducer needs two of each other independent means, the mass-afflicted ones serving as a closing element of the suction line Piston and the spring causing the piston to vibrate, both of which are to be coordinated. Since the piston slides in a guide in the suction line, frictional resistances of variable magnitude occur, which affect the response of the can delay or prevent vibratory system in an unforeseeable way.
Demgegenüber besteht das Neue der Erfindung darin, daß der Schwinger aus einem der Ansaug- oder Auspuffleitung zugeschalteten Gassack besteht. Der Schwinger benötigt in diesem Falle nur ein Mittel, das das massenbehaftete Abschlußorgan und das schwingungsfähige Mittel zugleich ist oder unmittelbar durch das Leitungsmittel (Gemisch oder Abgase) gebildet wird. Es ist hierzu nur ein von der Ansaug- oder Auspuffleitung abgezweigtes geschlossenes Rohr nötig, dessen Achse zur Durchflußrichtung der Saugleitung etwa senkrecht steht. Dieser Drehzahlbegrenzer arbeitet nahezu massenlos und reibungslos, da die im Rohr schwingende Gassäule durch ihre Wandreibung fast keinen Widerstand erfährt. Dieser Drehzahlbegrenzer verursacht keinen besonderen Aufwand; er kann auch nachträglich leicht an der Ansaug- oder Auspuffleitung angebracht werden. Dieser Drehzahlbegrenzer ist außerdem unbedingt betriebssicher und erfordert keinerlei überwachung. Infolge seiner Anspruchslosigkeit kann er für Kleinmooren mit besonderem Erfolg verwendet werden.In contrast, the novelty of the invention is that the oscillator consists of a gas bag connected to the intake or exhaust line. The Schwinger needs in this case only one means that the mass-afflicted closing organ and the vibratory means is at the same time or directly through the line means (Mixture or exhaust gases) is formed. It is only one of the suction or Exhaust pipe branched off closed pipe necessary, its axis to the direction of flow the suction line is approximately vertical. This speed limiter works almost massless and smoothly, as the gas column swinging in the pipe is almost due to its wall friction experiences no resistance. This speed limiter does not cause a special one Expenditure; it can also be easily retrofitted to the intake or exhaust line will. This speed limiter is also absolutely reliable and required no monitoring whatsoever. As a result of his modesty, he can go for peat bogs can be used with particular success.
Der Gegenstand der Erfindung ist in der Zeichnung näher veranschaulicht. Es zeigen: Fig. i die Ansicht einer Maschine mit einem Drehzahlbegrenzer, teilweise im Schnitt, und Fig. 2 das Schaubild der Resonanzkuive für die Ansaugleitung.The subject matter of the invention is illustrated in more detail in the drawing. They show: FIG. 1 a view of a machine with a speed limiter, partially in section, and FIG. 2 shows the diagram of the resonance cuive for the intake line.
Die Brennkraftmaschine ist als Antriebsmaschine kleiner Leistung für Krafträder ausgebildet und arbeitet nach dem Zweitaktverfahren. Der mit Kühlrippen versehene Zylinder 2 ist mit dem Kurbelgehäuse 3 verschraubt, in dem die Kurbelwelle., gelagert ist. Das Kurbelgehäuse 3 ist unter Vermittlung der Pratzen 5 an dein Rahmen des Kraftrades befestigt. Der Zylinder 2 ist mit einem Ansaugstutzen ; und einem Auspuffstutzen ß versehen; seine ansaug-, Spül- und Auspuffschlitze sind vom Kolben gesteuert. Im Zylinderkopf ist die Zündkerze 6 eingesetzt.The internal combustion engine is used as a prime mover for low power Motorcycles trained and works according to the two-stroke process. The one with cooling fins provided cylinder 2 is screwed to the crankcase 3, in which the crankshaft., is stored. The crankcase 3 is mediated by the claws 5 on your frame of Motorcycle attached. The cylinder 2 is provided with an intake manifold ; and an exhaust port ß; its intake, scavenging and exhaust ports are controlled by the piston. The spark plug 6 is inserted in the cylinder head.
An dem Ansaugstutzen 7 ist das Saugrohr 9 angeschlossen, von dem im rechten Winkel ein Rohr 16 abzweigt, das einen Sack io bildet. Das untere Ende des Rohres 16, das mit Innengewinde 14. versehen ist, wird hierbei durch einen verstellbaren Schraubenpfropfen 15 abgeschlossen. An das Saugrohr 9 ist der Vergaser i i angeschlossen, der den Luftfilter 12 trägt. Der Vergaser i i ist mit einer verstellbaren Drosselklappe 13 ausgerüstet, durch die die Füllung der Maschine in bekannter Weise geregelt wird. Die Luft tritt durch den Filter 12 in den Vergaser i i und wird hier je nach Stellung der Drosselklappe 13 mit Brennstoff angereichert. Das Gemisch durchströmt das Saugrohr 9, tritt unter dem Kolben in das Kurbelgehäuse 3 ein, -wird hier vorverdichtet und strömt schließlich im Arbeitstakt der Maschine über die Spülschlitze in den Zylinder 2.At the intake 7, the suction pipe 9 is connected, from which in the A pipe 16 branches off at right angles, which forms a sack io. The lower end of the Tube 16, which is provided with internal thread 14, is here by an adjustable Screw plug 15 completed. The carburetor i i is connected to the intake manifold 9, who carries the air filter 12. The carburetor i i has an adjustable throttle 13 equipped, through which the filling of the machine is regulated in a known manner. The air passes through the filter 12 into the carburetor i i and is here depending on the position the throttle valve 13 enriched with fuel. The mixture flows through the intake manifold 9, enters the crankcase 3 under the piston, is pre-compressed here and finally flows into the cylinder via the flushing slots in the work cycle of the machine 2.
Durch das periodische Schließen der Ansaugschlitze wird die Luftsäule zwischen diesen und dem Vergaser i i einschließlich des Sackes io zu stehenden Längsschwingungen angeregt: die normalerweise von kleiner Amplitude sind. Die Länge L des Sackes i o ist nun so bemessen, daß diese Schwingungen bei der Grenzdrehzahl, z. B. 3ooo UpM, in Resonanz geraten, d. h. eine steile Wellenfront bilden, was die ordnungsgemäße Füllung der Maschine unterbindet. Beträgt der Saugdruck bei einer bestimmten Stellung der Drossel z. B. ioo mm WS, -wie Fig. 2 zeigt, so bleibt dieser Unterdruck bis nahe an die Grenzdrehzahl im wesentlichen aufrecht. Bei dieser Grenzdrehzahl steigt er jedoch plötzlich auf den Wert 4.oo mm WS an und bewirkt, daß zu reiches Gemisch in die Maschine gelangt. Dadurch setzt die Zündung aus, der Arbeitsgang der Maschine wird unterbrochen, und die Leistung fällt so lange ab, bis eine niedrigere Drehzahl erreicht ist, bei der die Maschine wieder mit zündfähigem Gemisch gespeist werden kann.The periodic closing of the suction slots increases the air column between these and the carburetor i i including the bag io to standing longitudinal vibrations excited: which are normally of small amplitude. The length L of the bag i o is now dimensioned so that these vibrations at the limit speed, z. B. 3ooo Rpm, resonated, i.e. H. forming a steep wavefront, which is the proper Stops filling the machine. Is the suction pressure at a certain position the throttle z. B. 100 mm WS, -as Fig. 2 shows, this negative pressure remains until substantially upright close to the limit speed. At this limit speed increases However, it suddenly rises to a value of 400 mm WS and causes the mixture to be too rich got into the machine. This stops the ignition, the machine's operation is interrupted and the power drops until a lower speed is reached, at which the machine can be fed again with an ignitable mixture can.
Durch Veränderung der Länge L des Gassackes i o kann die Resonanzfrequenz in einen anderen Drehzahlbereich verlegt werden. Die Einstellung erfolgt durch den im Gewinde 1,1 sitzenden Pfropfen 15, der von dem unteren Ende des Rohres 16 her verstellbar ist.By changing the length L of the airbag i o, the resonance frequency moved to a different speed range. The setting is made by the plug 15 seated in the thread 1.1, which extends from the lower end of the tube 16 is adjustable.
Dieser Drehzahlbegrenzer kann auch für die schwingende Auspuffsäule Verwendung finden, wobei der Sack io am Auspuffstutzen ä untergebracht ist. In diesem Falle wird durch die Resonanzschwingungen die Gasabfuhr unterbrochen und die Spülung der Maschine gehemmt, so daß beim Erreichen der Grenzdrehzahl kein Frischgas mehr in den Zylinder gelangen kann. .This speed limiter can also be used for the swinging exhaust column Find use, where the bag io is housed on the exhaust port ä. In this Trap, the gas discharge and the purging are interrupted by the resonance vibrations the machine is inhibited, so that when the limit speed is reached, no more fresh gas can get into the cylinder. .
