Abstract

The ignition system for a multicylinder IC engine is based upon electronic units not requiring a mechanical distributor. The unit has a pair of ignition coils (10) each of which serves half of the cylinder plugs. The underside of the housing has connections to the plugs of two cylinders directly. Other connections to the remaining plugs (22,24) are made via leads (22,24). The housing (10) has a heat sink plate (32) of aluminium mounted on the top surface and this projects through an aperture in a plastic cover.

Description

Die Erfindung betrifft eine verteilerlose Zündanlage nach Patentanmeldung P 41 05 585.3.The invention relates to a distributorless ignition system according to patent application P 41 05 585.3.

Wie in der Stammanmeldung beschrieben, besitzt die Hälf­ te der Zylinder Zündspulen, die direkt den Zündkerzen zugeordnet sind, während die andere Hälfte der Zylinder Zündkerzen besitzt, die über Hochspannungskabel jeweils mit einer der Zündspulen verbunden sind.As described in the parent application, Hälf has te the cylinder ignition coils, which directly the spark plugs are assigned while the other half of the cylinders Has spark plugs, each via high-voltage cable are connected to one of the ignition coils.

Dabei ist es wünschenswert, zu einer besonders günstigen Bauform zu gelangen, die den Montageaufwand verringert.It is desirable to get a particularly affordable one Design to arrive, which reduces the assembly effort.

Die Aufgabe wird gelöst durch den Hauptanspruch.The task is solved by the main claim.

Erfindungsgemäß ist vorgesehen, daß die Zündspulen für die Zylinder zu einer Einheit zusammengefaßt werden, also beispielsweise bei einer Vierzylinder-Brennkraftma­ schine zwei Zündspulen als eine Einheit betrieben wer­ den. In einem Gehäuse zusammengefaßt ist ein Blechpaket, in dem die Zündkerzenstecker direkt vorgesehen sind, wobei der Abstand zwischen den Zündkerzensteckern selbstverständlich auf die geometrischen Anordnungen der Brennkraftmaschine abgestimmt ist, so daß im Abstand der Zündkerzen der Brennkraftmaschine aus der Unterseite des Gehäuses zwei Zündkerzenstecker herausragen, die direkt auf die Zündkerzen aufgesteckt werden können. Damit ist die gesamte Verbindung der Zündspulen zu den Zündker­ zensteckern bereits hergestellt, lediglich die beiden anderen Zündkerzenstecker, die über Kabel mit den Zünd­ spulen verbunden sind, müssen auf die jeweils anderen Zündkerzen aufgesteckt werden.According to the invention it is provided that the ignition coils for the cylinders are combined into one unit, So for example with a four-cylinder internal combustion engine seem two ignition coils operated as one unit the. A laminated core is combined in a housing, in which the spark plug connectors are provided directly, the distance between the spark plug connectors of course on the geometric arrangements of the Internal combustion engine is tuned so that the distance Spark plugs of the internal combustion engine from the bottom of the Two spark plug plugs protrude from the housing, directly can be attached to the spark plugs. So that is the entire connection of the ignition coils to the spark plug already made, just the two other spark plug connector, which is connected to the ignition cable  coils are connected to each other Spark plugs are put on.

Dadurch wird eine leicht montierbare Einheit geschaffen, die zudem günstig so abgedichtet werden kann, daß die Störanfälligkeit auf ein Minimum reduziert wird.This creates an easily assembled unit which can also be sealed cheaply so that the Susceptibility to faults is reduced to a minimum.

Zudem wird die Anzahl der störanfälligen Hochspannungs­ verbindungen auf ein Minimum reduziert.In addition, the number of high voltage susceptible to failure connections reduced to a minimum.

Im folgenden wird die Erfindung anhand der einzigen Fi­ gur beschrieben. Mit dem Bezugszeichen 10 ist ein Gehäu­ se bezeichnet, das ein Blechpaket 12 als Teil der Zünd­ spulen besitzt. In diesem Gehäuse 10 sind die Zündspulen untergebracht, wobei 26 einen Anschlußstutzen für das Gehäuse 10 aufzeigt, an den die Stromzufuhr zu den Zünd­ spulen befestigt werden kann.In the following the invention will be described with reference to the single Fi gur. The reference numeral 10 denotes a housing which has a laminated core 12 as part of the ignition coils. In this housing 10 , the ignition coils are housed, with 26 showing a connection piece for the housing 10 , to which the power supply to the ignition coils can be attached.

An der Unterseite des Gehäuses 10 ragen nach unten zwei Zündkerzenstecker 14 und 16 heraus, die auf zwei neben­ einanderliegende Zündkerzen, die zwei nicht im Gleich­ takt laufenden Zylindern zugeordnet sind, aufgesteckt werden können. In dem dargestellten Beispiel einer üb­ lichen Reihen-Vierzylinder-Brennkraftmaschine können al­ so die Zündkerzenstecker 14 und 16 den Zylindern 1 und 2 oder 3 und 4 zugeordnet werden, nicht jedoch den Zylin­ dern 2 und 3, die in einem Abstand von 360° Kurbelwel­ lenwinkel betrieben werden.On the underside of the housing 10, two spark plug connectors 14 and 16 protrude downwards, which can be plugged onto two adjacent spark plugs, which are assigned to two cylinders not running in the same cycle. In the illustrated example of a usual in-line four-cylinder internal combustion engine, al so the spark plug connectors 14 and 16 can be assigned to cylinders 1 and 2 or 3 and 4 , but not the cylinders 2 and 3 , which are at an interval of 360 ° crankshaft lenwinkel operate.

Aus dem Gehäuse 10 herausgeführt werden zwei Hochspan­ nungskabel 18 und 20, die an ihren Enden jeweils Zünd­ kerzenstecker 22 und 24 tragen, die auf die noch freien Zündkerzen aufgesteckt werden. Die Hochspannungskabel können fest eingespritzt sein oder alternativ über Steckkupplungen angeschlossen sein.Lead out of the housing 10 are two high-voltage cables 18 and 20 , each of which carries spark plug connectors 22 and 24 at their ends, which are plugged onto the still free spark plugs. The high-voltage cables can be permanently injected or alternatively connected via plug-in couplings.

Die Zuordnung, die dabei zu beachten ist, ist in der Stammanmeldung ausführlich dargestellt.The assignment that must be observed is in the Master registration shown in detail.
