Definitions
- the present invention relates to an element for coupling energy into a certain medium filled space, for example in the form of a spark plug for Ignition of an air-fuel mixture located in a combustion chamber of an internal combustion engine. Furthermore, the present invention relates to a device for Energy coupling into a room filled with a certain medium with several such elements, in particular a device for coupling energy into a an air-fuel mixture-filled combustion chamber of an internal combustion engine to the air-fuel mixture to ignite.
- DE 196 36 712 A1 describes a possibility for improving the ignition behavior proposed, wherein a plurality of ignition electrodes simultaneously in the combustion chamber to be arranged and to be supplied with the ignition voltage. That way Several flame cores are formed at the same time, so that an ignition zone is larger Expansion can be generated, which ensures reliable ignition of problematic air-fuel mixtures should allow.
- a problem associated with this ignition system is however, the high design effort to provide suitable spark plugs and the required space on the internal combustion engine itself.
- Ignition methods for the ignition of air-fuel mixtures have therefore been used Internal combustion engines proposed, with the help of plasma discharges thermal Energy introduced into the combustion chamber of the respective internal combustion engine or is coupled in to ignite the air-fuel mixture.
- Plasma is ignited by an electrode protruding into the combustion chamber
- Combustion chamber located air-fuel mixture ignites that the air-fuel mixture through a high frequency field of sufficient energy to a reactive Temperature is brought up by the air-fuel mixture through the by the electrode in the combustion chamber coupled high-frequency field in the electrically conductive plasma state brought.
- Such a device based on plasma discharge or plasma ignition is known for example from EP 0 211 133 B1.
- the electrode is a spark plug, which protrudes into the combustion chamber of an internal combustion engine, directly with one over one Circuit breaker clocked high frequency generator connected.
- the one from that High frequency generator generates high frequency power / high frequency energy in one of emitted by the electrode into the combustion chamber of the respective internal combustion engine High-frequency field for plasma ignition of the air-fuel mixture contained therein radiated.
- Electrode emitted radio frequency field to regulate to a high voltage in such a way that at the electrode in the air-fuel mixture, a plurality of high-resistance at the same time Form plasma threads of short duration.
- a number becomes short-term and intense producing plasma threads, which lead to short-term, intensive discharges of the Lead to plasma and cause a lot of flame nuclei in the air-fuel mixture, whereby a particularly good ignition behavior of the air-fuel mixture is achieved leaves.
- the geometry of the electrode is to be evaluated such that field strength increases of the high-frequency field emitted by the electrode, which are used for Form the short-term plasma threads in the air-fuel mixture.
- the ignition systems described above have in common that to ignite the in the Air-fuel mixture located in each combustion chamber is relatively high Energy consumption of the corresponding ignitor is required. By at the Discharges occurring at certain points also lead to a relatively strong discharge Wear of the electrode, which is also referred to as electrode erosion.
- the present invention is therefore based on the object, for example in the form a spark plug designed element for coupling energy into one with a certain medium, for example an air-fuel mixture, filled space To provide the most effective coupling of the electrode of the Elements supplied energy in the corresponding room while protecting the Electrode allows.
- the present invention is preferred for coupling energy into the combustion chamber an internal combustion engine, for example a gasoline engine with direct injection, is suitable for using an air / fuel mixture in the combustion chamber
- the present invention goes without saying to ignite plasma discharge basically also applicable to spark plugs, which according to the principle of Spark discharge work.
- the present invention is not limited to that Energy coupling into the combustion chamber of an internal combustion engine is limited, but can also to other possible areas of application in which energy is coupled into one space filled with a certain medium is required.
- Figure 1 shows a combustion chamber of an internal combustion engine with multiple spark plugs according to a first embodiment of the present invention
- FIG. 2 shows an enlarged illustration of the spark plug shown in FIG. 1, and
- Figure 3 shows an arrangement of two spark plugs according to a second Embodiment of the present invention.
- the combustion chamber or cylinder 1 of an internal combustion engine for example of a gasoline engine with direct injection
- an injection nozzle 3 for supplying an air-fuel mixture in Direction of arrow is provided in the upper part of the Combustion chamber 1
- a piston 2 is vertical in the combustion chamber 1 slidably mounted, which for compressing the supplied via the injection nozzle 3 Air-fuel mixture is used to ignite the air-fuel mixture facilitate.
- spark plugs 8 are shown in FIG. 1, which are in the combustion chamber 1 protrude.
- the spark plugs 8 comprise an electrode 9, which is used to couple a ignition energy used to ignite the supplied air / fuel mixture is provided.
- Electrodes 9 of the spark plugs 8 a high-frequency energy of a high-frequency generator 4 supplied so that from the electrodes 9 based on the supplied radio frequency energy a corresponding high-frequency field is emitted into the combustion chamber 1 in order to Air-fuel mixture injected between the electrodes 9 by means of plasma discharge ignite.
- the high-frequency generator 4 generates a high-frequency power signal generated with a frequency of preferably several kHz, which is initially from a Amplifier 5 amplifies and via a transformer 6 the electrodes 9 of the two spark plugs 8 is supplied. With the help of the transformer or transformer 6 it is ensured that none galvanic contact between the electrodes 9 and the amplifier 5 or High-frequency generator 4 is required, but that of the high-frequency generator generated radio frequency energy is galvanically decoupled, i.e. contactless on the Electrodes 9 transferred so that a contamination-proof coupling of the High frequency or ignition energy is guaranteed. This is particularly advantageous because because in conventional ignition devices with a direct contact between the in the Electrodes projecting into the combustion chamber and the high-frequency generator the contact points are susceptible to contamination and thus for the ignition of the in the combustion chamber existing fuel-air mixture represent a source of error.
- the spark plug 8 shown in FIG. 1 is shown enlarged in FIG. 2.
- the electrode 9 in the longitudinal direction through the Spark plug 8 extending electrode portion 12, the upper end as a connection serves to supply the high-frequency energy generated by the high-frequency generator 4.
- the end region of the electrode 9 protruding into the combustion chamber 1 comprises several elongated and comb-like electrode sections 10, each with the in Longitudinal direction of the spark plug 8 extending electrode section 12 are connected and to Coupling the ignition energy in the combustion chamber 1 serve.
- the electrode sections 10 run in different Transverse planes to the longitudinal axis of the spark plug 8 or to the electrode section 12 to one another parallel.
- the electrode sections 10 are located in the combustion chamber 1 protruding outer surface of the spark plug 8 essentially in the circumferential direction designed semi-circular (of course, the electrode sections 10 can each can also be circular along the entire circumference of the spark plug 8).
- the spark plugs 8 are to be arranged as shown in FIG. 1 in such a way that they are at the lower end of the spark plugs 8 formed electrode sections 10 are facing each other.
- At Application of the high-frequency energy generated by the high-frequency generator 4 are on this way between the individual electrode sections 10 of the electrode 9 of the two Spark plugs 8 distribute occurring, high-frequency discharges with a large surface generated, which thus form a "discharge curtain" 7 and an energy-saving and reliable ignition of the "discharge curtain” or "plasma curtain” extending injection jet of the air-fuel mixture enables.
- insulating coatings 11 for example made of a ceramic material, isolated from each other.
- FIG. 3 shows two spark plugs 8 according to a second exemplary embodiment of the presented present invention.
- this is Embodiment the spark plug or the electrode 9 on the in the combustion chamber 1st protruding end region bent transversely to the longitudinal axis of the respective spark plug 8, where as in the previously described embodiment again several elongated Electrode sections 10 are provided which are connected to the spark plug 8 in the longitudinal direction extending electrode section 12 are connected and for coupling the Ignition energy supplied to the electrode section 12 serve in the combustion chamber 1.
- the single ones Electrode sections 10 are in turn insulated from one another by insulating layers 11.
- the Electrode sections 10 run analogously to the previously described embodiment essentially semicircular around the corresponding end region of the respective Spark plug 8 around.
- the two spark plugs 8 are to be arranged in the combustion chamber 1 in such a way that the Electrode sections 10 of the two spark plugs 8, as shown in FIG. 3, face each other are.
- the direction of the injection jet is again indicated by an arrow.
- the generation of several is distributed with the help of this arrangement Discharges occurring, which form a "discharge curtain" 7, between the Electrode sections 10 of the two spark plugs 8 generated, so that a large volume Ignition of the supplied between the electrode sections 10 of the two spark plugs 8 Air-fuel mixture is possible.
- This arrangement also does not occur a punctual discharge between the two spark plugs 8, but it occurs a large number of discharges, with which the area on which the ignition energy is applied to the Air-fuel mixture supplied acts in a significantly increased manner and thus the Ignition of the air-fuel mixture can be facilitated.
