Abstract
Description
Die Erfindung bezieht sich auf eine Ansaugvorrichtung für eine Kraftstoffmaschine bzw. Verbrennungsmaschine mit der Funktion der Luftzufuhr aus der Umgebung in einen Ansaugkanal, welcher in den Brennraum führt.The invention relates to an intake device for a fuel machine or Internal combustion engine with the function of air supply from the environment into one Intake duct that leads into the combustion chamber.
Der für die Verbrennung nötige Kraftstoff wird zum Beispiel mittels Vergaser oder Einspritzung an einer Stelle des Ansaugkanals oder direkt in den Brennraum zugeführt.The fuel required for combustion is supplied, for example, by means of a carburetor or injection a point of the intake duct or fed directly into the combustion chamber.
Die Erfindung bezieht sich also gattungsgemäß auf eine Ansaugvorrichtung für eine Kraftstoffmaschine. Eine herkömmliche Ansaugvorrichtung (Fig. 1 und 2) besteht in den aller meisten Fällen aus einem Gehäuse, bestehend aus Boden (Fig. 1 und 2, 3), Deckel (Fig. 1, 6) und Luftfilter (Fig. 1 und 2, 2), welches mit dem Ansaugkanal (Fig. 1, 5) des Vergasers bzw. der Einspritzanlage verbunden ist. Die Umgebungsluft (Fig. 1 und 2, 1) gelangt durch eine Eintrittsöffnung in das Gehäuse, passiert den Luftfilter (Fig. 1 und 2, 2) und strömt daraufhin in den Ansaugkanal (Fig. 1, 5).The invention therefore relates generically to an intake device for a fuel machine. A conventional suction device ( Fig. 1 and 2) consists in most cases of a housing consisting of the bottom ( Fig. 1 and 2, 3 ), cover ( Fig. 1, 6 ) and air filter ( Fig. 1 and 2, 2 ), which is connected to the intake duct ( Fig. 1, 5 ) of the carburetor or the injection system. The ambient air ( Fig. 1 and 2, 1 ) enters the housing through an inlet opening, passes through the air filter ( Fig. 1 and 2, 2 ) and then flows into the intake duct ( Fig. 1, 5 ).
Herkömmliche Ansaugvorrichtungen sind ohne besondere Vorrichtungen, welche die Luftströmung begünstigen, konstruiert. Als einziges Merkmal einer Verbesserung der Luftströmung ist oftmals der Übergang bzw. die Öffnung von der Ansaugvorrichtung zum Ansaugkanal verrundet (Fig. 1 und 2, 4).Conventional suction devices are constructed without special devices which favor the air flow. The only feature of an improvement in the air flow is often the transition or opening from the suction device to the suction channel ( FIGS. 1 and 2, 4 ).
Bei vielen, bestehenden Ansaugvorrichtungen prallen die Luftströmungen beim Eintritt in den Ansaugkanal aufeinander (Fig. 1 und 2, 10) und bilden den Ansaugvorgang behindernde Einrollwirbel (Fig. 1, 11), deren Drehachse (Fig. 1, 12) senkrecht zum Ansaugkanal (Fig. 1, 5) verläuft.In many existing suction devices, the air flows collide with each other when entering the suction channel (FIGS . 1 and 2, 10 ) and form roll-in vortices (FIGS . 1, 11 ) that hinder the suction process, the axis of rotation ( FIGS. 1, 12 ) of which is perpendicular to the suction channel ( Fig. 1, 5 ) runs.
Dadurch muss die Kraftstoff- bzw. Verbrennungsmaschine mehr Arbeit für das Ansaugen der benötigten Verbrennungsluft verrichten.As a result, the fuel or internal combustion engine needs more work for the intake of the perform the required combustion air.
Eine ungünstige Luftströmung mit Einrollwirbeln (Fig. 1, 11), verursacht durch beste hende Ansaugvorrichtungen, hat ausserdem einen negativen Einfluss auf die Gemischbildung und erhöht die Saugrohrverluste. Dadurch verschlechtert sich der Wirkungsgrad der Verbrennungsmaschine. Ebenso werden mehr Abgase produziert.An unfavorable air flow with curling vortices ( Fig. 1, 11 ), caused by existing suction devices, also has a negative influence on the mixture formation and increases the intake manifold losses. As a result, the efficiency of the internal combustion engine deteriorates. Likewise, more exhaust gases are produced.
Die vorliegende Erfindung soll daher folgende Probleme lösen bzw. folgende Anforderungen
erfüllen:
Die Luftströmung im Ansaugkanal soll wesentlich verbessert werden. Das heisst, die
Verbrennungsmaschine soll von der Saugarbeit deutlich entlastet werden.The present invention is therefore intended to solve the following problems or meet the following requirements:
The air flow in the intake duct is to be significantly improved. This means that the internal combustion engine should be significantly relieved of the suction work.
Die Gemischbildung soll begünstigt werden: Es soll ein feineres Luft-Kraftstoff-Gemisch gebildet werden.The mixture formation should be favored: It should be a finer air-fuel mixture be formed.
Die Saugrohrverluste bzw. der Niederschlag von Kraftstoff an den Wänden des Ansaugkanals soll verringert werden. The intake manifold losses or the precipitation of fuel on the walls of the intake duct should be reduced.
Durch das Zusammenwirken von besserer Luftströmung, feinerer Gemischbildung und verrin gerten Saugrohrverlusten soll die Effektivität, die Leistung und das Abgasverhalten der Verbrennungsmaschine positiv beeinflusst werden.Through the interaction of better air flow, finer mixture formation and reduced Intake manifold losses should reduce the effectiveness, performance and exhaust gas behavior of the Internal combustion engine can be influenced positively.
Diese Anforderungen werden erfindungsgemäss dadurch erfüllt, dass die Form der in dieser Erfindung beschriebenen Ansaugvorrichtung so gestaltet ist, dass die angesaugte Luft in einer schraubenförmigen Wirbelbewegung in den Ansaugkanal eingeführt wird, wobei die Dreh- Achse des somit erzeugten, schraubenförmigen Luftwirbels parallel zum Ansaugkanal verläuft.According to the invention, these requirements are met in that the shape of the Intake device described invention is designed so that the intake air in a helical swirl movement is introduced into the intake duct, the rotary The axis of the helical air vortex thus generated runs parallel to the intake duct.
Fig. 3 und Fig. 4 zeigen eine mögliche Ausgestaltung der Erfindung. Die Ansaugvorrichtung
enthält hierzu speziell geformte Leitschaufeln (Fig. 3 und 4, 13), welche beim
Luftdurchlauf einen schraubenartigen Luftwirbel (Fig. 3 und 4, 11) erzeugen:
Die Umgebungsluft (Fig. 3 und 4, 1) passiert den Luftfilter (Fig. 3 und 4, 2) und strömt
zwischen den Leitschaufeln (Fig. 3 und 4, 10) zur Öffnung des Ansaugkanals (Fig. 3 und 4,
4). Die Leitschaufeln (Fig. 3 und 4, 13) sind so geformt, dass der Luftstrom (Fig. 3 und
4, 10) nicht senkrecht zur Öffnung des Ansaugkanals (Fig. 3 und 4, 4) eintrifft, son
dern schräg. Dadurch prallen die Luftströme nicht mehr aufeinander, sondern es entsteht ein
schraubenartiger Luftwirbel (Fig. 3 und 4, 11), dessen Drehachse (Fig. 4, 12) idealer
weise parallel zum Ansaugkanal (Fig. 4, 5) verläuft. Fig. 3 and Fig. 4 show a possible embodiment of the invention. For this purpose, the suction device contains specially shaped guide vanes ( FIGS. 3 and 4, 13 ), which generate a screw-like air vortex ( FIGS. 3 and 4, 11 ) during the passage of air:
The ambient air ( Fig. 3 and 4, 1 ) passes the air filter ( Fig. 3 and 4, 2 ) and flows between the guide vanes ( Fig. 3 and 4, 10 ) to open the intake duct ( Fig. 3 and 4, 4 ) , The guide vanes ( Fig. 3 and 4, 13 ) are shaped so that the air flow ( Fig. 3 and 4, 10 ) does not arrive perpendicular to the opening of the intake duct ( Fig. 3 and 4, 4 ), but at an angle. As a result, the air streams no longer collide with each other, but a screw-like air vortex ( FIGS. 3 and 4, 11 ) arises, whose axis of rotation ( FIGS. 4, 12 ) ideally runs parallel to the intake duct ( FIGS. 4, 5 ).
Durch eine gemäss dieser Erfindung beschriebene Ausgestaltung einer Ansaugvorrichtung werden die den Luftstrom behindernden Einrollwirbel (Fig. 1, 11) vermieden. Der Luftstrom wird erfindungsgemäss in eine schraubenartige Wirbelbewegung (Fig. 3 und 4, 11) gebracht, deren Drehachse (Fig. 4, 12) parallel zum Ansaugkanal (Fig. 4, 5) ver läuft.The design of a suction device described in accordance with this invention avoids the curling vortices (FIGS . 1, 11 ) which obstruct the air flow. The air flow is brought according to the invention in a screw-like vortex movement ( Fig. 3 and 4, 11 ), the axis of rotation ( Fig. 4, 12 ) parallel to the intake duct ( Fig. 4, 5 ) runs ver.
Ein so ausgbildeter und ausgerichteter Schraubenwirbel hat die Eigenschaft, sich über den gesamten Verlauf des Ansaugkanals (Fig. 4, 5), auch wenn dieser gekrümmt ist, bis zum Einlassventil bzw. Brennraum (Fig. 4, 9) fortzusetzen.A screw vortex designed and aligned in this way has the property of continuing over the entire course of the intake duct ( FIGS. 4, 5 ), even if it is curved, to the inlet valve or combustion chamber ( FIGS. 4, 9 ).
Die erfindungsgemäss erzeugte, schraubenförmige Luftströmung kann für die Verbrennungsmaschine mit weniger Energieaufwand angesaugt werden, da sich die Luft bzw. das Luft-Kraftstoff-Gemisch durch den gesamten Ansaugkanal "durchschraubt", ohne blockie rende Einrollwirbel (Fig. 1, 11) zu erzeugen.The helical air flow generated according to the invention can be sucked in for the internal combustion engine with less energy expenditure, since the air or the air-fuel mixture “screws through” through the entire intake duct without producing blocking curling vortices (FIGS . 1, 11 ).
Ein weiterer Vorteil des erfindungsgemäss erzeugten Luftwirbels besteht darin, dass dessen Drehbewegung an verengten Stellen des Ansaugkanals, zum Beispiel an der Drosselklappe (Fig. 4, 7), beschleunigt wird, da sich hier der Durchmesser des schraubenartigen Luftwirbels verringert. Da der Drehimpuls des Luftwirbels gleichbleiben muss, wird gemäss der Impulserhaltung die Drehfrequenz erhöht. Hierdurch wird, gemäss Anspruch 2 der vorlie genden Erfindung, im Beispiel einer Vergaseranordnung mit Kraftstoffdüse (Fig. 4, 8) eine zuvor unerreicht feine Gemischbildung ermöglicht.Another advantage of the air vortex produced according to the invention is that its rotational movement is accelerated at narrowed points in the intake duct, for example at the throttle valve ( FIGS. 4, 7 ), since the diameter of the screw-like air vortex is reduced here. Since the angular momentum of the air vortex must remain constant, the rotational frequency is increased according to the conservation of momentum. This enables, according to claim 2 of the vorlie invention, in the example of a carburetor arrangement with a fuel nozzle ( Fig. 4, 8 ) a previously unattainable fine mixture formation.
Die erfindungsgemäss erzeugte, schraubenförmige Luftströmung hat ausserdem die Eigenschaft, das Kraftstoff-Luft-Gemisch mit weniger Wandberührung transportieren zu kön nen. Hierdurch wird der Niederschlag von Kraftstoff an den Wänden des Ansaugkanals und die damit verbundenen Saugrohrverluste verringert. The helical air flow generated according to the invention also has the Property of being able to transport the fuel-air mixture with less wall contact NEN. This will cause the precipitation of fuel on the walls of the intake duct and the associated intake pipe losses are reduced.
Fig. 5 zeigt eine weitere, mögliche Ausgestaltung der vorliegenden Erfindung:
Die Ansaugvorrichtung hat hier eine Schneckenform (Fig. 5, 3). Die Umgebungsluft (Fig.
5, 1) gelangt durch den Luftfilter (Fig. 5, 2) und bildet eine durch die
Schneckenform vorgegebene Luftströmung (Fig. 5, 10). Fig. 5 shows another possible embodiment of the present invention:
The suction device has a screw shape here ( Fig. 5, 3 ). The ambient air ( Fig. 5, 1 ) passes through the air filter ( Fig. 5, 2 ) and forms an air flow ( Fig. 5, 10 ) predetermined by the shape of the screw.
Im Zentrum der Schneckenform mündet die im Sinne der vorliegenden Erfindung gestaltete Ansaugvorrichtung in den Ansaugkanal (Fig. 5, 4). Hier entsteht durch die schneckenför mig umgeleitete Luftströmung ein schraubenartiger Luftwirbel (Fig. 5, 11) mit zum Ansaugkanal parallel verlaufender Drehachse. In the center of the screw shape, the suction device designed in the sense of the present invention opens into the suction channel ( FIGS. 5, 4 ). This creates a screw-like air vortex ( Fig. 5, 11 ) with the axis of rotation running parallel to the intake duct by the snail-shaped redirected air flow.
