Description

Es- gibt bekanntlich Zündanlagen zum Betrieb von Brennkraftmaschinen, bei denen jede Zündkerze mit einer besonderen Zündspule zusammenarbeitet, welche zweckmäßig unmittelbar an der Zündkerze .angeordnet wind.. Derartige Zündeinrichtungen haben den Vorteil, daß sie ohne Hochspannungsverteilung arbeiten; als Nachteil ist dagegen zu verzeichnen, daß die einzelnen Zündspulen, verhältnü.sanäßig groß wenden.There are known ignition systems for the operation of internal combustion engines, where each spark plug works together with a special ignition coil, which expediently arranged directly on the spark plug. Such ignition devices have the advantage that they work without high voltage distribution; as a disadvantage On the other hand, it can be noted that the individual ignition coils turn relatively large.

Um dies zu vermeiden, .ist gemäß der Erfindung mindestens ein Vortransformator vorgesehen, welcher mit einer Gruppe von Einzelzündspulen zusammenarbeitet, und zwar derart, daß in den Primärstromkreis des Vortransformators ein Steuerunterbrecher eingeschaltet ist, während an seine Sekundärwicklung die Primärwicklungen der zu der Gruppe gehörenden Zündspulen über eine mit dem Sfieuerunterbrecher synchron umlaufende Schalteinrichtung angeschlossen sind. Bei einer derartigen Zündeinrichtung, bei welcher die Transformierung der Eingangsspannung auf die Zündspannung :in zwei Stufen erfolgt, kann der Primärstrom für den Vortransformator einer Aldkumulatorenbatterie entnommgn oderpermanentmagnetisch induziert werden. Eine an einen Vortransformator angeschlossene Gruppe von, Zündspulen kann dabei aus höchstens acht Zündspulen bestehen. Zum Betrieb von Brennkraftrmaschinen mit hoher Zylinderzahl sind daher mehrere Vortransformatoren erforderlich.In order to avoid this, at least one pre-transformer according to the invention provided, which cooperates with a group of individual ignition coils, and in such a way that a control breaker in the primary circuit of the pre-transformer is switched on, while the primary windings of the to its secondary winding The ignition coils belonging to the group are synchronized with the fire breaker circumferential switching device are connected. With such an ignition device, in which the transformation of the input voltage to the ignition voltage: in two Steps takes place, the primary current for the pre-transformer of an Aldkumulatorenbatterie removed or permanently magnetically induced. One to a pre-transformer Connected group of ignition coils can consist of a maximum of eight ignition coils. To operate internal combustion engines with a large number of cylinders, there are therefore several pre-transformers necessary.

In -der Abbildung, in welcher,eim Schaltbild einer Batteriezündanlage zum Betrieb einer Vierzylinderbrennkraftmaschine nach der Erfindung dargestellt ist, veranschaulicht a eine Akknmulatorenbatterie, welche einerseits über einen Schalter b mit der Primärwicklung c eines Vortransforrnators und andererseits mit einem Steuerunbenbrecher d und einem zu diesem parallel geschalteten Kondensator e verbunden ist.In the figure in which, a circuit diagram of a battery ignition system for operating a four-cylinder internal combustion engine according to the invention is, illustrates a Akknmulatorenbatterie, which on the one hand via a Switch b with the primary winding c of a pre-transformer and on the other hand with a control circuit breaker d and a capacitor connected in parallel to this e is connected.

Durch den Steuerunterbrecher d wird der in, der Wicklung e fließende Strom im Rhyfhanus der Arbeitstakte -der zu betreibenden Brenakraftmaschine unterbrochen. Die Sekundärwicklung f des Vortransformators liegt mit ihrem einen Ende an Masse, während .das andere Ende mit vier Schaltern g einer Verteilereinrichtung verbunden ist, durch welche jeweils im Zündzeitpunkt, d. h. bei der ölfnung ,des Steuerunterbrechers d, ein in ,der Sekundärwicklung f des Vortransformators induzierter Spannungsstoß auf die Primärwicklung h je einer Zündspule gegeben wird, deren eine Seite ebenfalls mit Masse verbunden ist. Vier derartige Zündspulen sind zum Betrieb einer Vierzylinderfirennkraftmaschnne erforderlich, in der Abbildung ist der Einfachheit halber jedoch nur eine dargestellt. An die Sekundärwicklung idieser Zündspulen ist je eine Zündkerze k in. einem Zylinder der zu Brennkraftmaschine angeschlossen. Die Übersetzungsverhältnisse des Vortransformators und der Zündspulen können beispielsweise so gewählt sein, daß der Vortransformator die Spannung auf 2ooo V vortransformiert, während säe durch die Zündspulen vollends auf die Zündspannung von ro ooo V erhöht wird.The control interrupter d causes the flow in the winding e Current in the rhyfhanus of the work cycles of the Brena power machine to be operated interrupted. One end of the secondary winding f of the pre-transformer is grounded, while .the other end is connected to four switches g of a distribution device is, by which in each case at the ignition point, d. H. at the opening of the control breaker d, a voltage surge induced in, the secondary winding f of the pre-transformer an ignition coil is given to the primary winding h, one side of which is also given is connected to ground. Four such ignition coils are used to operate a four-cylinder industrial engine required, but only one is shown in the illustration for the sake of simplicity. One spark plug each is connected to the secondary winding of these ignition coils in a cylinder connected to the internal combustion engine. The transformation ratios of the pre-transformer and the ignition coils can be chosen, for example, so that the pre-transformer the voltage is pretransformed to 2ooo V, while the ignition coils are completely used is increased to the ignition voltage of ro ooo V.
