Description

Stand der TechnikState of the art

Die Erfindung geht aus von einer Einrichtung zur Verstellung des Zündzeitpunktes für Brennkraftmaschinen nach der Gattung des Patentanspruchs 1. Eine solche Einrichtung ist durch die US-PS 3 780 713 bekannt. Mit einer Frühverstellung des Zündzeitpunktes im Leerlaufbetrieb erreicht man eine Kraftstoffersparnis von einigen Prozenten je 100 Fahrkilometem. Diese Frühverstellung wird bekanntlich nur angewendet mit elektronisch erzeugten Zündverstellinien. Nicht bekannt sind Zündverteiler mit einer mechanischen Einrichtung für eine entsprechende Verstellung sowohl bei Teillast als auch im Leerlauf bzw. Trennung des Start- und Leerlauf-Zündwinkels.The invention relates to a device for adjusting the ignition timing for internal combustion engines according to the preamble of claim 1. Such a device is known from US Pat. No. 3,780,713. With an early adjustment of the ignition timing in idle mode, fuel savings of a few percent per 100 kilometers are achieved. As is well known, this early adjustment is only used with electronically generated ignition adjustment lines. Ignition distributors with a mechanical device for a corresponding adjustment both at partial load and at idle or separation of the start and idle ignition angle are not known.

Vorteile der ErfindungAdvantages of the invention

Mit dem Zündverteiler für Brennkraftmaschinen nach der Erfindung wird die Zündzeitpunktverstellung ausgehend vom Startwinkel (Grundeinstellung) nach Früh sowohl bei Teillast als auch im Leerlauf durch eine mechanische Einrichtung bewirkt, die einen einfachen und sicherwirkenden Aufbau aufweist. Notorisch bekannt sind Einzeldosen für die Frühverstellung bei Teillastbetrieb und aus FR-A-2 168 836 und FR-A-2 435 611 sogenannte Doppeldosen mit einer zusätzlichen, der Abgasentgiftung dienenden Spätdose, die den Zündzeitpunkt im Leerlauf und Schiebebetrieb nach Spät verstellt. Die Erfindung macht sich den Umstand zunutze, daß bei eben geöffneter Drosselklappe der Teillastunterdruck an der Drosselklappe und der Saugraumunterdruck in Strömungsrichtung dahinter fast identisch sind.With the ignition distributor for internal combustion engines according to the invention, the ignition timing is adjusted starting from the starting angle (basic setting) after early, both at partial load and at idle speed, by a mechanical device which has a simple and safe-acting structure. Single cans for early adjustment in partial-load operation and from FR-A-2 168 836 and FR-A-2 435 611 so-called double cans are notoriously known. The invention takes advantage of the fact that when the throttle valve is open, the partial load vacuum on the throttle valve and the suction chamber vacuum in the flow direction behind it are almost identical.

FIG. 1 shows a reduced, scaled representation of the top view of an ignition distributor without a distributor flap with attached device and its connections to the intake manifold of the internal combustion engine; Figure 2 shows the axial section of the device in an enlarged view; and Figure 3 shows the diagram with the adjustment line at idle and at partial load.

Beschreibung des AusführungsbeispielesDescription of the embodiment

Von einem Zündverteiler für Brennkraftmaschinen zeigt Figur 1 ein Gehäuse 10 mit einer darin um eine Welle 12 schwenkbar gelagerten Platte 11, auf der ein Unterbrecherkontaktsatz 13 befestigt ist. Eine Einrichtung für die Verstellung des Zündzeitpunktes nach Früh bei Teillast und im Leerlauf der Brennkraftmaschine ist als Unterdruckdose 14 ausgebildet und durch einen Sockel 15 am Gehäuse 10 befestigt. Eine als Gestänge ausgebildete Zugstange 16 ist zum einen über einen Bolzen 17 an der Platte 11 angelenkt und zum anderen an einer Membran 28 (Figur 2) der Unterdruckdose 14 befestigt.1 shows a housing 10 of an ignition distributor for internal combustion engines with a plate 11 pivotably mounted therein about a shaft 12 and on which an interrupter contact set 13 is fastened. A device for adjusting the ignition timing after early at partial load and when the internal combustion engine is idling is designed as a vacuum socket 14 and fastened to the housing 10 by a base 15. A pull rod 16 designed as a linkage is articulated on the one hand via a bolt 17 on the plate 11 and, on the other hand, is fastened to a membrane 28 (FIG. 2) of the vacuum box 14.

Die Dose 14 verbindet eine Leitung 18 mit dem Saugbereich 19 kurz vor der Drosselklappe 21 des Ansaugkanals 20 der Brennkraftmaschine und eine Leitung 22 mit dem Saugbereich 23 in Strömungsrichtung 24 hinter der Drosselklappe 21. Dargestellt ist der Leerlauf bei geschlossener Drosselklappe 21 mit Atmosphärendruck im Saugbereich 19 und mit Unterdruck im Saugbereich 23. Ab Teillast mit nur geringfügig geöffneter " Drosselklappe 21' bis zur Vollast ist der Unterdruck in beiden Saugbereichen 191 23 annähernd gleich groß.The socket 14 connects a line 18 to the suction area 19 shortly before the throttle valve 21 of the intake duct 20 of the internal combustion engine and a line 22 to the suction area 23 in the flow direction 24 behind the throttle valve 21. The idle state is shown when the throttle valve 21 is closed with atmospheric pressure in the suction area 19 and with negative pressure in the suction area 23. From partial load with only slightly opened "throttle valve 21 'to full load, the negative pressure in both suction areas 19 1 23 is approximately the same size.

Die durch den Sockel 15 am Gehäuse 10 (Figur 2) des Zündverteilers befestigte Unterdruckdose 14 hat eine von einer ersten Halbschale 26 und einer gemeinsamen Membran 27 gebildete Arbeitskammer 25, in welche die Leitung 18 mündet. Des weiteren hat die Unterdruckdose 14 eine von der gemeinsamen Membran 27 unter einer ständig vom Atmosphärendruck beaufschlagten Membran 28 gebildete Leerlauf Arbeitskammer 29, in welche die Leitung 22 mündet. Ein aus Kunststoff hergestellter Ring 30 hat einen Außenbereich 31, der unter Zwischenlage beider Membranen 27, 28 in der ersten Halbschale 26 und einer zweiten Halbschale 32 eingebördelt ist, und dessen Innenbereich 33 einen Anschlag für die gemeinsame Membran 27 bildet.The vacuum box 14 fastened by the base 15 to the housing 10 (FIG. 2) of the ignition distributor has a working chamber 25 formed by a first half-shell 26 and a common membrane 27, into which the line 18 opens. Furthermore, the vacuum box 14 has an idle working chamber 29, formed by the common membrane 27 under a membrane 28 constantly subjected to atmospheric pressure, into which the line 22 opens. A ring 30 made of plastic has an outer region 31, which is crimped in the first half-shell 26 and a second half-shell 32 with the interposition of both membranes 27, 28, and whose inner region 33 forms a stop for the common membrane 27.

An beiden Seiten der gemeinsamen Membran 27 ist ein erster und zweiter Federteller 34, 35 durch einen Niet 36 befestigt, wobei in der Arbeitskammer 25 eine Rückholfeder 37 angeordnet, die sich an der Halbschale 26 und am Federteller 34 abstützt und dabei die gemeinsame Membran 27 über den Federteller 35 an den durch den Innenbereich 33 des Ringes 30 gebildeten ortsfesten Anschlag gedrückt hält. Ein Federteller 38 und eine Scheibe 39 sind unter Zwischenlage der Membran 28 am Endabschnitt der Zugstange 16 angenietet, die einen in die Leerlauf-Arbeitskammer 29 ragenden Stößel 40 aufweist ; dieses bildet einen Topf, welcher im Federteller 38 eingelegt ist, sowie einen Mittelteil 44, der einen aus Kunststoff gefertigten Anschlagbolzen 45 aufnimmt. Eine zweite Rückholfeder 43 mit einer geringeren Vorspannung als die der ersten Rückholfeder 37 ist zwischen dem Federteller 35 und den Armen 41, 42 des Stößels 40 eingespannt und distanziert beide Membranen 27, 28.On both sides of the common diaphragm 27, a first and second spring plate 34, 35 are fastened by a rivet 36, a return spring 37 being arranged in the working chamber 25, which is supported on the half-shell 26 and on the spring plate 34 and thereby the common diaphragm 27 holds the spring plate 35 against the stationary stop formed by the inner region 33 of the ring 30. A spring plate 38 and a washer 39 are riveted with the membrane 28 being interposed on the end section of the pull rod 16, which has a plunger 40 projecting into the idle working chamber 29; this forms a pot, which is inserted in the spring plate 38, and a central part 44, which receives a stop pin 45 made of plastic. A second return spring 43 with a lower preload than that of the first return spring 37 is clamped between the spring plate 35 and the arms 41, 42 of the plunger 40 and distances both diaphragms 27, 28.

Im Schaubild in Figur 3 ist auf der Vertikalen der Verstellwinkel a des Zündzeitpunktes nach Früh aufgetragen und auf der Horizontalen der Unterdruck P im zugehörigen Saugbereich der Brennkraftmaschine. Die Kennlinie 46 im Leerlauf und die Kennlinie 47 bei Teillast werden anhand der in Figur 2 im funktionslosen Zustand der Brennkraftmaschine dargestellten Unterdruckdose 14 folgt gebildet :In the diagram in FIG. 3, the adjustment angle α of the ignition timing after morning is plotted on the vertical and the negative pressure P in the associated suction area of the internal combustion engine is plotted on the horizontal. The characteristic curve 46 when idling and the characteristic curve 47 at partial load are based on the vacuum do shown in Figure 2 in the inoperative state of the internal combustion engine se 14 follows:

Der Start der Brennkraftmaschine erfolgt im Linienbereich 50 ohne Frühverstellung ; der sich anschließende Leerlauf oder Schubbetrieb bei geschlossener Drosselklappe 21 (Figur 1) bewirkt einen Unterdruck im Saugbereich 23 und mithin in der Leerlauf-Arbeitskammer 29, so daß nach Überwinden der Vorspannkraft der Rückholfeder 43 die Membran 28 mit der daran befestigten Zugstange 16 in Pfeilrichtung 49 soweit bewegt wird, bis der Bolzen 45 am Kopf des Nietes 36 anschlägt; diese Frühverstellung im Leerlauf gemäß Linienabschnitt 52 beginnt bei Punkt 51 und endet bei Punkt 53, ab dem gemäß Linienabschnitt 54 auch bei höherem Unterdruck aufgrund der größeren Vorspannkraft der Rückholfeder 37 keine Frühverstellung mehr erfolgt.The internal combustion engine is started in line area 50 without early adjustment; The subsequent idling or coasting operation with the throttle valve 21 closed (FIG. 1) creates a negative pressure in the suction area 23 and thus in the idling working chamber 29, so that after overcoming the pretensioning force of the return spring 43, the membrane 28 with the pull rod 16 attached thereto in the direction of arrow 49 is moved until the bolt 45 strikes the head of the rivet 36; this early adjustment in idle according to line section 52 begins at point 51 and ends at point 53, from which, according to line section 54, there is no longer an early adjustment even with a higher negative pressure due to the greater biasing force of the return spring 37.

Bereits bei niedrigster Teillast, d. h. schon bei geringfügig geöffneter Drosselklappe 21', herrscht in beiden Saugbereichen 19, 23 und mithin in beiden Arbeitskammem 25, 29 gleicher Unterdruck, so daß sich beide Membranen 25, 28 gleichzeitig und gleichmäßig entgegen der Kraft der Rückholfeder 37 so lange bewegen und dabei die Zugstange 16 gemäß Pfeil 49 verstellen, bis diese Verstellung ein nicht gezeichneter Anschlag begrenzt ; diese Verstellung des Zündzeitpunktes nach Früh bei Teillast erfolgt gemäß Teillinie 58 und endet in Punkt 59, ab dem trotz gegebenenfalls erhöhtem Unterdruck gemäß Teillinie 60 keine erhöhte Frühverstellung mehr erfolgt. Beim Übergang von Teillast zu Vollast wird die Verstellinie 47, beginnend bei 59 und endend bei 51, 50 unter Ausklammerung der Linie 46 durchlaufen.Even at the lowest partial load, i.e. H. even with the throttle valve 21 'slightly open, there is the same negative pressure in both suction areas 19, 23 and therefore in both working chambers 25, 29, so that both diaphragms 25, 28 move simultaneously and uniformly against the force of the return spring 37 for as long as the pull rod 16 adjust according to arrow 49 until this adjustment limits a stop not shown; this adjustment of the ignition timing after early at partial load takes place according to part line 58 and ends at point 59, from which, despite the possibly increased vacuum according to part line 60, there is no increased early adjustment. During the transition from part load to full load, the adjustment line 47 is started, starting at 59 and ending at 51, 50, excluding line 46.

Varianten der Verstellinien 46, 47 sind in an sich bekannter Weise darstellbar, insbesondere durch Verändern der Charakteristik beider Rückholfedern 37, 43 und der beiden Membranen.Variants of the adjustment lines 46, 47 can be represented in a manner known per se, in particular by changing the characteristics of both return springs 37, 43 and the two membranes.
