Definitions
- the invention is based on an ignition coil arrangement for multi-cylinder internal combustion engines according to the type of claim 1.
- Such an ignition coil arrangement is known from DE 36 10 067 C3.
- the ignition coil arrangement consists of several coil units, each controlled by an output stage, in the manner of multiple ignition coils.
- Each coil unit consists of a primary coil and a secondary coil connected to two spark plugs. All coil units are combined to form a structural unit with a common housing.
- the ignition coil arrangement is of large construction, so that the installation of such an ignition coil arrangement can be difficult in the confined spaces in the engine compartment of an internal combustion engine.
- the ignition coil arrangement according to the invention with the characterizing features of claim 1 has the advantage that the aforementioned inadequacy is avoided to a satisfactory extent.
- the ignition coil arrangement voltage at least one coil unit as a multiple ignition coil, the primary coil and secondary coil are each divided and mechanically separated. A primary coil section and a secondary coil section are combined to form a coil section and several coil sections are electrically connected in series.
- the ignition coil assembly consists of several small units, each of which, due to its small construction volume, in particular in the case of a rod core design, can also be placed under cramped installation conditions, so that this ignition coil assembly can be used in many different ways and can be manufactured in large numbers and thus inexpensively.
- An ignition coil arrangement for a multi-cylinder internal combustion engine is composed of several identical coil units 11 in the manner of multiple ignition coils, realized as double ignition coils, one of which is shown in the figure.
- Each coil unit 11 contains a primary coil 12 and a secondary coil 14 connected to two spark plugs 13 and is controlled by a switching element 16 in the form of an output stage, here symbolized by the switching symbol of a transistor.
- Both the primary coil 12 and the secondary coil 14 are mechanically and spatially separated into two primary coil sections 17 and two secondary coil sections 18, respectively.
- a primary coil 17 and a secondary coil 18 together with an iron core 19 arranged therein form a first coil Sub-coil 21 or second sub-coil 22 summarized.
- Each of the partial coils 21, 22 is arranged in a housing 23.
- each of the two primary part coils is connected to a common primary connecting line 24 and the one end of the two secondary part coils 18 is connected to a common secondary connecting line 26.
- a coil unit 11 with a switching element 16 can also consist of three or more primary part coils 17 or secondary part coils 18 with the same structure and serial interconnection.
