Abstract

The invention relates to a mechanical injection pump governor with an atmosphere and charging pressure-related torque control (2) for an air-compressing combustion engine, on which a delivery adjustment element (10) interacts with an intermediate lever (4), which as control-side transmission element between a load connection leading to the accelerator pedal and a delivery adjusting element (8) of the injection pump leading via reversing lever (5) and control lever (6) and determining the control travel, can be designed so that it can be isolated from a swivel member (9) as part of the torque control (2) in such a way that up to a certain adjusting lever angle the control travel can be varied only as a function of the load, but independently of the charging pressure, and beyond this adjusting lever angle solely according to the charging pressure building up as a function of the charging pressure and load in the direction of increased delivery. <IMAGE>

Description

Die Erfindung betrifft einen mechanischen Einspritzpumpenregler mit einer atmosphären- und ladedruckabhängigen Angleichvor­richtung für eine luftverdichtende Brennkraftmaschine gemäß den im Oberbegriff des Patentanspruchs angegebenen Merkmalen.The invention relates to a mechanical injection pump controller with an atmospheric and boost pressure-dependent adjustment device for an air-compressing internal combustion engine according to the features specified in the preamble of the claim.

Aus der DE-OS 37 36 781 ist ein derartiger Einspritzpumpenreg­ler bekannt, bei der ein Mengenkorrekturglied der Angleichvor­richtung über einen als Kulissenkörper ausgebildeten Schwenk­körper auf einen mit diesem in der Kulisse geführten Umlenkhe­bel mengenkorrigierend wirkt.Such an injection pump regulator is known from DE-OS 37 36 781, in which a quantity correction element of the adjustment device acts via a pivot body designed as a link body on a deflection lever guided with it in the link, and has a quantity-correcting effect.

In der Kulisse ist neben dem Umlenkhebel zusätzlich ein mit dem Verstellhebel verbundener Zwischenhebel geführt, über den bei einer Lasteingabe der Umlenkhebel, der Regelhebel und schließ­lich das Mengenverstellglied verstellt wird. Bei dieser Aus­führung bewirkt eine Ladedruckänderung immer eine Einspritz­mengenänderung sowie im Teillastbereich der Brennkraftmaschine auch eine unerwünschte Drehmomentänderung, obwohl der Fahrer das Gaspedal in seiner Stellung nicht verändert.In addition to the deflection lever, an intermediate lever connected to the adjustment lever is also guided in the backdrop, via which the deflection lever, the control lever and finally the quantity adjustment element are adjusted when a load is input. In this embodiment, a change in boost pressure always causes a change in the injection quantity and also an undesirable change in torque in the part-load range of the internal combustion engine, although the driver does not change the position of the accelerator pedal.

Beim Anfahren aus dem Stand wird z.B. das Gaspedal voll durch­getreten, um eine Maximalbeschleunigung durchführen zu können. Wird dann der Ladedruck wirksam, so erhöht sich rasch die Ein­spritzmenge, wodurch eine vom Fahrer nicht beabsichtigte Voll­lastbeschleunigung bewirkt wird, die bei bestimmten Verkehrssi­tuationen nicht ungefährlich ist.When starting from a standing position, e.g. the accelerator pedal is fully depressed to allow maximum acceleration. If the boost pressure then becomes effective, the injection quantity increases rapidly, as a result of which a full-load acceleration which is not intended by the driver and which is not harmless in certain traffic situations is brought about.

Der Erfindung liegt daher die Aufgabe zugrunde, diese Mängel durch einfache Maßnahmen im Einspritzpumpenregler abzuwenden.The invention is therefore based on the object of averting these deficiencies by simple measures in the injection pump controller.

Zur Lösung dieser Aufgabe dienen die im Kennzeichen des Pa­tentanspruchs I angegebenen Merkmale, durch die die eingangs genannten Mängel behoben werden.To solve this problem, the features specified in the characterizing part of patent claim I serve to remedy the shortcomings mentioned at the outset.

Durch die Entkoppelung des lastabhängigen Übertragungsgliedes von dem ladedruckabhängigen Schwenkkörper ist es möglich, daß beim Anfahren aus dem Stand die maximale Einspritzmenge bereits unterhalb der Vollastanschlagstellung des Gaspedals erreichbar ist und beim Wirksamwerden des Ladedrucks der Regelweg bei un­veränderter Stellung des Gaspedals gehalten werden kann. Es erfolgt somit kein ladedruckabhängiger Schub, auf den der Fah­rer keinen Einfluß nehmen kann, vielmehr hat der Fahrer die Möglichkeit, über das Gaspedal eine Anpassung an den steigenden Ladedruck vorzunehmen (detaillierte Erläuterungen sind im be­schreibenden Teil angegeben).By decoupling the load-dependent transmission element from the charge-pressure-dependent swivel body, it is possible that when starting from a standstill, the maximum injection quantity can already be reached below the full-throttle position of the accelerator pedal and when the boost pressure becomes effective, the control path can be maintained with the accelerator pedal in the same position. There is therefore no boost dependent on boost pressure, which the driver cannot influence, but the driver has the option of using the accelerator pedal to adapt to the increasing boost pressure (detailed explanations are given in the descriptive part).

In den Unteransprüchen sind erfindungsgemäß förderliche Wei­terbildungen angegeben.Advantageous further developments according to the invention are specified in the subclaims.

Als vorteilhafte Maßnahmen gemäß Anspruch 5 wird angesehen, daß eine zwangsläufige Begrenzung des Gaspedals bei einer Bewegung in Richtung Vollaststellung beim Anschlagen des Anschlagbolzens an den Gegenanschlag verhindert wird.It is regarded as advantageous measures according to claim 5 that an inevitable limitation of the accelerator pedal during a movement in the direction of the full load position is prevented when the stop bolt strikes the counter stop.

Die Erfindung ist anhand von in der Zeichnung veranschaulichten Ausführungsbeispielen näher beschrieben. Es zeigen:

  • Fig. 1 ein Funktionsschema des mechanischen Einspritz­pumpenreglers mit atmosphären- und ladedruckabhän­giger Angleichvorrichtung,
  • Fig. 2 den Regler in Seitenansicht,
  • Fig. 3 ein Kennfeld mit einer Regelwegkennlinie, bei dem der Regelweg mit RW und der Verstellhebelwinkel mit VH-W Grad angegeben ist,
  • Fig. 4 ein bekanntes Kennfeld, in dem die gesamten Regel­wegkennlinien in Abhängigkeit vom Ladedruck stehen.
The invention is described in more detail with reference to exemplary embodiments illustrated in the drawing. Show it:
  • 1 is a functional diagram of the mechanical injection pump controller with atmospheric and boost pressure-dependent adjustment device,
  • 2 the controller in side view,
  • 3 is a characteristic diagram with a control path characteristic curve, in which the control path is indicated with RW and the adjusting lever angle with VH-W degrees,
  • Fig. 4 shows a known map in which the entire control path characteristics are dependent on the boost pressure.

Bei einem in Fig. 1 schematisch dargestellten mechanischen Einspritzpumpenregler 1 mit einer atmosphären- und ladedruck­abhängigen Angleichvorrichtung 2 für eine luftverdichtende, selbstzündende Brennkraftmaschine erfolgt die Lasteingabe von einem mit dem Gaspedal (nicht gezeigt) verbundenen Verstellhe­bel 3 über einen Zwischenhebel als Übertragungsglied 4 und ei­nen Umlenkhebel 5 auf einen Regelhebel 6 und über eine Lasche 7 auf das als Regelstange ausgebildete Mengenverstellglied 8.In the case of a mechanical injection pump regulator 1, shown schematically in FIG. 1, with an adjustment device 2 which is dependent on the atmospheric and boost pressure for an air-compressing, self-igniting internal combustion engine, the load is input from an adjusting lever 3 connected to the accelerator pedal (not shown) via an intermediate lever as a transmission element 4 and a deflection lever 5 on a control lever 6 and via a tab 7 on the quantity adjusting element 8 designed as a control rod.

Das Übertragungsglied 4 steht mit einem Schwenkkörper 9 als Teil der Angleichvorrichtung 2 in Wirkverbindung, der die Form eines Winkelhebels hat, dessen nach oben ragender Schenkel 9a an einem Mengenkorrekturglied 10 der Angleichvorrichtung ange­lenkt ist und dessen seitwärts verlaufender Schenkel 9b auf einem Lagerbolzen 11 drehbar gelagert ist, der seinerseits am Reglergehäuse 1a (Fig.2) drehfest eingespannt ist. Der bei La­dedruckzunahme entgegen dem Uhrzeigersinn drehbare Schwenkkör­per 9 ist an der Unterseite seines Schenkels 9b mit einer Gleitbahn 12 versehen, die auch bei bestimmten Ladedruckzuständen als Gegenanschlag für einen Anschlag 13 am Übertragungsglied 4 dient. Dieser Anschlag 13 ist als An­schlagbolzen ausgebildet und liegt etwa in Längsmitte des abgewinkelt ausgeführten Übertragungsgliedes 4, dessen eines Ende einen Lagerbolzen 4a aufweist, der in einer Kulisse 5a des Führungshebels 5 geführt ist, und dessen anderes Ende mit einer Verstellhebelwelle 14 drehfest verbunden ist.The transmission member 4 is operatively connected to a swivel body 9 as part of the adjustment device 2, which has the shape of an angle lever, the upwardly projecting leg 9a of which is articulated on a quantity correction member 10 of the adjustment device and the laterally extending leg 9b is rotatably mounted on a bearing pin 11 , which in turn is clamped on the controller housing 1a (FIG. 2) in a rotationally fixed manner. The swivel body 9, which can be rotated counterclockwise when the boost pressure increases, is provided on the underside of its leg 9b with a slideway 12, which also applies to certain ones Boost pressure conditions serves as a counter-stop for a stop 13 on the transmission member 4. This stop 13 is designed as a stop pin and lies approximately in the longitudinal center of the angled transmission member 4, one end of which has a bearing pin 4a which is guided in a link 5a of the guide lever 5, and the other end of which is connected in a rotationally fixed manner to an adjusting lever shaft 14.

In der Lastverbindung zwischen dem Gaspedal und dem Verstell­hebel 3 ist ein Überdrückglied 15 mit einer Ausgleichsfeder 16 angeordnet, die nachgibt, sobald beim Niedertreten des Gaspe­dals das Übertragungsglied an den Schwenkkörper 9 anschlägt.In the load connection between the accelerator pedal and the adjusting lever 3, an overpressure member 15 with a compensating spring 16 is arranged, which yields as soon as the transmission member strikes the swivel body 9 when the accelerator pedal is depressed.

Wirkungsweise:Mode of action:

Durch die besondere Entkoppelung des ladedruckabhängigen Ein­griffs in die Einspritzmengenzuteilung (Fig.3) erfolgt gegen­über der bekannten Ausführung nach Fig. 4 eine Beeinflussung der Einspritzmenge im Teillastbereich nur last-, jedoch nicht ladedruckabhängig und ferner nur in dem Fall, wenn durch das Gaspedal eine Mehrmenge angefordert wird, bei der das Grenz­lambda (∼1.2λ) bei dem augenblicklich vorliegenden Ladedruck unterschritten ist.Due to the special decoupling of the charge pressure-dependent intervention in the injection quantity allocation (FIG. 3), compared to the known embodiment according to FIG. 4, the injection quantity in the part-load range is influenced only as a function of the load, but not as a function of the charge pressure, and also only in the case when the accelerator pedal causes an excess is requested at which the limit lambda (∼1.2λ) falls below the current boost pressure.

Beispiel:Example:

Der Verstellhebelwinkel von 50° entspricht der Vollastan­schlagstellung des Gaspedals. Tritt nun der Fahrer das Gaspedal bis zu einem Verstellhebelwinkel von 35° durch, was einem Re­gelweg von ca. 9 mm entspricht, und wird anschließend der La­dedruck bis zu einem Wert von ca. 1200 mbar wirksam, so verän­dert sich der Regelweg erst, wenn vom Fahrer über das Gaspedal eine Mehrmenge angefordert wird.The adjustment lever angle of 50 ° corresponds to the full load stop position of the accelerator pedal. If the driver now depresses the accelerator pedal up to an adjustment lever angle of 35 °, which corresponds to a control path of approx. 9 mm, and if the boost pressure is then effective up to a value of approx. 1200 mbar, the control path only changes when the Driver using the accelerator pedal to request a surplus.

Somit wird verhindert, daß beim Wirksamwerden des Ladedrucks ein vom Fahrer ungewollter Schub des Fahrzeugs auftritt, wie es z.B. bei der bekannten Ausführung gemäß Fig. 4 der Fall wäre. Hier muß der Fahrer bei gleichem Regelweg von 9 mm das Gaspedal bis zum Anschlag (50° VH-W) durchtreten. Der nachfolgende La­dedruck verändert schlagartig den Regelweg ohne Einflußnahme des Fahrers. Das Fahrzeug läßt sich schwer beherrschen. Im Teillastbereich erfolgt ebenfalls eine Änderung der Einspritz­menge durch eine Ladedruckänderung, die ein unruhiges Motor­verhalten auslöst.This prevents an undesired thrust of the vehicle from occurring when the boost pressure comes into effect, as e.g. would be the case in the known embodiment according to FIG. 4. Here the driver must depress the accelerator pedal as far as the stop (50 ° VH-W) with the same control range of 9 mm. The subsequent boost pressure suddenly changes the control path without the driver's influence. The vehicle is difficult to control. In the part-load range, the injection quantity is also changed by changing the boost pressure, which triggers uneasy engine behavior.
