Description
Einspritzvorrichtung für Brennkraftmaschinen mit Druckzerstäubung Die Erfindung bezieht sich auf eine Einspritzvorrichtung für Brennkraftmaschinen mit Druckzerstäubung, bei welcher mehrere symmetrisch auf den Umfang des Arbeitszylinders verteilte Einspritzdüsen vorgesehen sind, von denen einzelne Gruppen im Zusammenhang mit Belastungsänderungen der Maschine ab- und zugeschaltet werden können, und besteht darin, daß Einspritzdüsen, welche eine abschaltbare Gruppe bilden, einander gegenüberliegend angeordnet sind, so daß bei der Ab- und Zuschaltung einer Gruppe jeweils Düsengruppen, welche gegenüberliegende Sektoren des Verbrennungsraumes bestreichen, in Tätigkeit bleiben und bei jedem Belastungszustand der Maschine eine symmetrische Verteilung des Brennstoffes im Verbrennungsraum gewahrt bleibt.Injection device for internal combustion engines with pressure atomization The invention relates to an injection device for internal combustion engines with pressure atomization, in which several symmetrically on the circumference of the working cylinder distributed injectors are provided, of which individual groups are related can be switched on and off with changes in the load on the machine, and exists in that injection nozzles, which form a disconnectable group, are opposite one another are arranged so that when a group is switched off and on, nozzle groups, which line opposite sectors of the combustion chamber, in action and a symmetrical distribution for every load condition of the machine of the fuel in the combustion chamber is preserved.
Der Erfindungsgegenstand ist auf der Zeichnung schematisch dargestellt.The subject of the invention is shown schematically in the drawing.
i ist der Arbeitszylinder, auf dessen Umfang die Einspritzdüsen bzw. -ventile 2, 3, d., 5 symmetrisch angeordnet sind. 6 und 7 sind Brennstoffdruckleitungen, in denen Rückschlagventile 8 und 9 und Sicherheitsventile io und ii vorgesehen sind. 12 ist das Gehäuse einer gemeinsamen Steuervorrichtung für die Einspritzventile, in welche die an die (nicht gezeichnete) Brennstoffpumpe angeschlossenen Leitungen 13 und 14 einmünden. Die Steuerwelle, auf welcher die Nocken 17 und 18 sitzen, ist mit 15, die Regelwelle mit 16 bezeichnet. Diese wird vermittels des Hebels i9 unter dem Einfluß des Reglers der Belastung entsprechend gedreht, so daß das Gestänge 2o, 21 bzw. 22, 23 stärker oder schwächer mit den Nocken 17 und 18 in Eingriff gebracht wird. Im Steuergehäuse i-: sind die federbelasteten Ventile 2q. und 25 eingebaut. Die Nocken 17 und 18 können unter gleichem Winkel oder unter voneinander verschiedenen Winkeln auf der Steuerwelle 15 aufgekeilt sein, so daß entweder alle Düsen gleichzeitig einspritzen oder beispielsweise zuerst das Düsenpaar 3, 5 und erst hierauf das Düsenpaar 2, q..i is the working cylinder, on the circumference of which the injection nozzles or valves 2, 3, d., 5 are arranged symmetrically. 6 and 7 are fuel pressure lines in which check valves 8 and 9 and safety valves io and ii are provided. 12 is the housing of a common control device for the injection valves into which the lines 13 and 14 connected to the fuel pump (not shown) open. The control shaft on which the cams 17 and 18 sit is denoted by 15 and the control shaft by 16. This is rotated by means of the lever i9 under the influence of the controller of the load, so that the linkage 2o, 21 or 22, 23 is brought more or less into engagement with the cams 17 and 18. In the control housing i-: are the spring-loaded valves 2q. and 25 installed. The cams 17 and 18 can be keyed at the same angle or at different angles on the control shaft 15, so that either all nozzles inject simultaneously or, for example, first the nozzle pair 3, 5 and only then the nozzle pair 2, q ..
Die Vorrichtung arbeitet wie folgt: Der von der Brennstoffpumpe auf Einspritzdruck gepreßte Brennstoff wird in den Räumen 26 und 27 aufgespeichert, bis der auf den Ventilen 24. und 25 lastende Federdruck unter der Einwirkung des Steuergestänges 21 und 23 aufgehoben wird. Ist dies geschehen, so strömt der Brennstoff durch die geöffneten Ventile einerseits durch die Leitung 6 zu den Einspritzdüsen 3 und 5, andererseits durch die Leitung 7 zu den Einspritzdüsen 2 und .4. Falls eine Düsengruppe, z. B. die Düsen 3 und 5, die von der gemeinsamen Leitung 6 gespeist werden, abgeschaltet wird, so verteilt die weiterarbeitende Gruppe den Brennstoff immer noch auf einander gegenüberliegende Sektoren des Verbrennungsraumes; die Verteilung bleibt demnach bei jeder Schaltstellung symmetrisch, so daß eine gleichmäßige Verbrennung gewährleistet ist.The device works as follows: The one from the fuel pump Injection pressure injected fuel is stored in spaces 26 and 27, until the spring pressure on the valves 24 and 25 under the action of the Control linkage 21 and 23 is canceled. Once this has happened, the fuel flows through the opened valves on the one hand through line 6 to the injection nozzles 3 and 5, on the other hand through the line 7 to the injection nozzles 2 and .4. If a nozzle group, e.g. B. the nozzles 3 and 5, which are fed by the common line 6 is switched off, the group that continues to work distributes the fuel still on opposite sectors of the combustion chamber; the distribution therefore remains symmetrical in every switching position, so that even combustion is guaranteed.
Durch die Rückschlagventile 8 und 9, die zwischen den Einspritzventilen und den Steuerorganen eingebaut sind, wird ein Zurückschlagen des Brennstoffes verhindert. Durch die Sicherheitsventile io und ii wird unzulässigen Druckerhöhungen und dadurch bedingten Stauungen vorgebeugt.Through the check valves 8 and 9 between the injectors and the control elements are installed, a kickback of the fuel is prevented. By the safety valves io and ii becomes impermissible pressure increases and thereby conditional congestion prevented.
