Definitions
- Such a capacitor serves to increase the energy contained in the spark head of the ignition spark and thus to achieve ignition of even particularly lean mixtures with the help of this spark head.
- So-called breakdown spark plugs have been known for some time, in which the capacitor is integrated in the spark plug. On the one hand, this leads to a significantly increased overall height of the spark plug and, on the other hand, that such spark plugs only have a short service life. Both problems present considerable difficulties in modern motor vehicle construction and have led to the fact that spark plugs of this type have not been used.
- the invention has for its object to provide an ignition system of the type mentioned, which forms the capacitor in a structurally simple manner and without increasing the overall height of the spark plug.
- the invention solves this problem in an ignition system of this type by the means specified in the characterizing part of patent claim 1.
- the capacitor is thus formed between the hollow body and the channel.
- the intermediate insulation body prevents flashovers between the hollow body and the channel. In this way it is possible to construct such a capacitor in a constructive manner without changing the commercially available spark plug and thus to achieve the desired energy enrichment of the spark head.
- the structural possibility of changing the length of the sleeve in relatively wide areas makes it possible to produce capacitors of a defined capacitance. This possibility is supported by the choice of a suitable dialectrical material for the insulation body. In this way it is possible to vary the capacitance in a wide range with regard to its capacitance by constructive design of the sleeve and selection of the suitable insulation body.
- an ignition system for an internal combustion engine is shown in section, which is partially shown as a section.
- the ignition system is designed as a single coil ignition system 1 and is arranged in a cylinder head 2 of an internal combustion engine which is only partially shown.
- a cylinder is partially shown with its bearings 3 and 4 for camshafts, not shown, which are located on the intake and exhaust sides.
- the single-coil ignition system 1 consists of an overhead, schematically shown ignition coil 5 and a high-voltage supply in the form of a sleeve 6 and a connection contact 7.
- the sleeve 6 is designed in stages and is located in a channel 8 of the internal combustion engine. It overlaps the connector 7 and the upper part of a spark plug 9, which is electrically connected to the connector 7 via a mating contact 10.
- the insulation body 11 consists of a material with a high dielectric constant.
- the sleeve 6 together with the insulation body 11 forms a capacitor, the electrodes of which are formed by the sleeve 6 and the inside of the channel 8 in the cylinder head 2 of the internal combustion engine.
- the cylinder head 2 is made of metal and is at the same electrical potential as the - not shown - ground electrode of the spark plug 9.
- the capacitor formed in this way leads to a significant increase in the energy contained in the spark head of the ignition spark, which is formed in the spark plug between the two electrodes. In this way it is possible to ignite even particularly lean mixtures in the manner of a breakdown ignition with the help of the spark head. In this way, reproducible and exact ignition conditions within the individual cylinders of the internal combustion engine are achieved.
- the sleeve 6, which essentially serves as a high-voltage supply and electrical connection between the ignition coil 1 and the spark plug 9, is in one piece with the ignition coil 1 or the insulating body surrounding it (not shown in detail). In this way it is possible, after a prepared insertion of the insulation body 11 into the channel 8 by attaching the single-coil ignition system 1, to form the capacitor and to achieve the desired ignition effect without additional measures and using a commercially available spark plug 9 which is not changed further.
