Description
Gemischregler für Einspritz-Otto-Motoren Die Erfindung geht von Gemischreglern für Einspritz-Otto-Motoren aus, bei denen mittels eines Staurohres in der Ansaugleitung die Gemischzusammensetzung geändert wird.Mixture regulator for injection gasoline engines The invention is based on mixture regulators for injection gasoline engines, where a pitot tube in the intake line the mixture composition is changed.
Bei einer bekannten Einrichtung dieser Art ist die öffnung des Staurohres in Abhängigkeit vom Gang der Maschine gegenüber der Anströmrichtung der angesaugten Luft verstellbar, um auf die Regeleinrichtung entweder den statischen oder den Gesamtdruck wirken zu lassen. Die hierfür erforderliche bewegliche Anordnung des Staurohres erfordert besondere Verstellvorrichtungen, die den Aufbau und den Betrieb der Anlage erschweren.In a known device of this type, the opening of the pitot tube is depending on the gear of the machine in relation to the direction of flow of the sucked in Air adjustable to either the static or the total pressure on the control device let it work. The movable arrangement of the pitot tube required for this requires special adjustment devices that structure and operate the system make more difficult.
Demgegenüber kennzeichnet sich der _ Gemischregler nach der Erfindung dadurch, daß die öffnung des Staurohres bis zur Erreichung der Dauerlast im Windschatten der Drosselklappe liegt und von da an zum Zwecke der Gemischanreicherung dem vollen Staudruck der Ansaugluft ausgesetzt ist. Hierdurch wird der Vorteil erreicht, daß das Staurohr fest in die Ansaugleitung eingebaut werden kann und daß keine zusätzlichen Einrichtungen zu seiner Bewegung erforderlich sind.In contrast, the _ mixture regulator according to the invention is characterized in that the opening of the pitot tube is in the slipstream until the permanent load is reached the throttle valve and from then on to the full for the purpose of mixture enrichment Is exposed to dynamic pressure of the intake air. This has the advantage that the pitot tube can be permanently installed in the suction line and that no additional Facilities are required for its movement.
In der Zeichnung sind zwei Ausführungsbeispiele der Erfindung im Längsschnitt dargestellt.In the drawing, two exemplary embodiments of the invention are shown in longitudinal section shown.
Das Staurohr A ist erfindungsgemäß so hinter der Drosselklappe B in der Ansaugleitung F untergebracht, daß seine Mündung bis zur Erreichung der Dauerlast im Windschatten der Drosselklappe B liegt, von da an jedoch dem vollen Staudruck der angesaugten Luft ausgesetzt ist. Es ist durch ein Rohr J mit dem Regler G verbunden, der über ein Gestänge H eine hier nicht gezeichnete Brenn stoffpumpe beeinflußt. In Abb. 2 ist statt der einfachen Staudüse ein U-förmig gebogenes Rohr verwendet, das seinen engsten Querschnitt bei C hat und in öffnungen D; E von rechteckigem Querschnitt endet (vgl. Schnitt a-b). Es ist durch :eine Bohrung bei C mit dem Rohr J verbunden, das zum Regler G führt. Solange die nach innen zu liegende öffnung E noch im Windschatten der DrosselklappeD liegt, strömt die bei D eintretende Ansaugluft bei E wieder aus, ohne sich vor der Bohrung bei C zu stauen. Wird jedoch auch die Düsenöffnung E beim Überschreiten der Stellung für Dauerlast von der Drosselklappe freigegeben, so kann der volle dynamische Druck der angesaugten Luft auf den Regler G einwirken. Es wird also auch hier wie bei der einfachen Düse nach Abb. i ein plötzlicher Druckanstieg erzielt, der die je Zeiteinheit einzuspritzende Kraftstoffmenge in der gewünschten Weisse vergrößert. Der besondere Vorteil des U-förmig gebogenen Rohres vor der eigentlichen Düsenöffnung bei C gemäß Abb. 2 ist jedoch, daß h?er der Druckanstieg in weiten Grenzen nach Beliehen festgelegt werden kann.According to the invention, the pitot tube A is behind the throttle valve B in the intake line F accommodated that its mouth until the continuous load is reached lies in the slipstream of throttle valve B, but from then on the full dynamic pressure is exposed to the sucked in air. It is connected to the regulator G by a pipe J, which influences a fuel pump, not shown here, via a linkage H. In Fig. 2 a U-shaped bent tube is used instead of the simple nozzle, that has its narrowest cross-section at C and in openings D; E of rectangular Cross section ends (see section a-b). It's through: a hole at C with the pipe J connected, which leads to controller G. As long as the opening to the inside E is still in the slipstream of the throttle valve D, the intake air entering at D flows off again at E without jamming in front of the bore at C. However, also the Nozzle opening E when the position for continuous load of the throttle valve is exceeded released, the full dynamic pressure of the air drawn in can be applied to the regulator G act. So here too, as with the simple nozzle according to Fig. 1, it becomes a sudden one Pressure increase achieved, which the amount of fuel to be injected per unit of time in the desired whiteness enlarged. The particular advantage of the U-shaped bent Pipe in front of the actual nozzle opening at C according to Fig. 2 is that higher the pressure increase can be determined within wide limits after borrowing.
