Definitions
- the present invention relates, in general, to an ignition process for a heat engine.
- radio frequency spark plugs adapted to generate a branched spark from the tip of an electrode.
- radiofrequency spark plugs are adapted, in particular by the shape and arrangement of their electrodes, to generate a branched spark when this electrode is powered using an alternating electric signal of higher frequency 1 MHz.
- a branched spark produced by a radiofrequency candle is more likely to ignite a mixture of oxidant and fuel than a linear spark from a conventional candle, since the branched spark extends into a zone of volume greater than the area in which extends the linear spark produced by a conventional candle.
- the invention therefore relates more particularly to a method for igniting a mixture of oxidant and fuel in a combustion chamber of a combustion engine using a radiofrequency spark plug generating a branched spark from the tip of an electrode, the spark plug being arranged to open into said combustion chamber of the engine, the method comprising a first step of feeding said spark plug to the using a first AC signal of higher frequency 1 MHz.
- the document FR2913297 proposes a method of ignition using a radiofrequency ignition plug in which a resonator is controlled during ignition by means of a control signal in the form of a plurality of transmission trains. pulses, each train having a very short duration, for example from 5 to 10 ⁇ s. This command consists in making multi-ignitions.
- supply of the candle consists of feeding the electrode of the candle with a tip using a higher frequency alternating electric signal. at lMhz, in this case it is a supply of the pointed electrode by alternative signals hereinafter called the first and second alternative electrical signals.
- This type of ignition process performed by supplying at least one spark plug with an AC electrical signal with a frequency greater than 1 MHz is known as a radiofrequency ignition process.
- the ignition method of the invention is essentially characterized in that it comprises a second step of feeding said spark plug to using a second signal alternating electric frequency higher than 1 MHz, this second step being subsequent to the first step and being spaced in time with respect to the first step of a spacing period.
- the spark produced by the candle when powered with an electrical signal of frequency greater than 1 MHz has a shape that branches in the mixture and generally has several branches.
- the spark has several portions whose diameter decreases going from the origin of the spark (that is to say at the point where the spark ignites) towards its ends (the place where the spark ceases to spread). It has been noticed that the temperature of the spark varies along the spark and decreases with the diameter of the spark portions. The flame in the mixture is initiated at the hottest spots of the mixture, i.e. at the spark portions that have the largest diameters. It has also been found that when two sparks are triggered consecutively and prior to ignition of the mixture, the second spark occurs substantially at the same location as the first spark while having fewer branches.
- the mixture is preheated in the vicinity of the sparks produced by the first step, then thanks to the second step, producing less branched sparks, the temperature rise continues beyond the temperature obtained by the first step and this to initiate combustion.
- the mixing volume in which the combustion caused by the second stage is initiated is therefore greater than the volume of mixture which would be ignited via the first step alone.
- the ignition of the mixture present in the combustion chamber is initiated by at least two distinct signals of respective frequencies greater than 1 MHz which generate respectively at least two radiofrequency sparks.
- the volume of inflamed mixture is greater than it would be if the ignition was initiated by a single electrical signal.
- the invention thus makes it possible to reduce the number of ignition misfires and the unburnt fuel volume while increasing the flame propagation speed in the chamber.
- said spacing time between the first and second steps is less than 10 times the duration of the first step and preferably less than 5 times the duration of the first step.
- This feature limits the delay between the two candle power signals so as to minimize the risk of cooling the mixture preheated by the first spark, which is a condition that improves the size of the ignited mixture volume.
- the spacing interval between the first and second steps is greater than the duration of the first step.
- this minimum delay condition between the two stages / sparks makes it possible to reduce the number of branches of the second spark relative to the first spark. Allowing for an extension of the branches and an increase in the average diameter of the branches of the second spark relative to the first spark. This average diameter is calculated over the length of a given spark branch. It can also be ensured that the spacing interval between the first and second steps is between 1 and 5 times the duration of the first step.
- said first and second signals have respective frequencies preferably greater than 1 MHz
- each of said first and second electrical signals has specific parameters such as the voltage amplitude of the signal U, the frequency of the alternating electric signal F, the total duration of the signal D, and that one at least parameters of at least one of said first and second signals are determined during a step prior to said first and second steps as a function of parameters determining the combustion, these parameters determining the combustion being measured and / or estimated and comprising at least one pressure in the combustion chamber P, a temperature T representative of the temperature inside the chamber, the richness of the mixture of fuel and oxidant, and a rate of burnt gases present in the mixture.
- Determining at least one of the parameters of at least one of the first and second signals as a function of operating characteristics of the engine makes it possible to adapt the nature of the spark produced during the first and / or second step depending on the conditions prevailing in the chamber which optimizes the ignition conditions.
- the duration of the first step is between 150 and 250 ⁇ s
- that the duration of the second step is between 150 and 250 ⁇ s and that said spacing interval between the first and second stages is included. between 250 and 750 ⁇ .
- the first signal is emitted during the entire first step and only during this first step.
- the second signal is emitted during the entire second step and only during this second step.
- the formation time of the flame front core in the combustion chamber is about 2000 ⁇ s, which is particularly fast and that while increasing the rate of ignition successful.
- the invention also relates to a system for igniting a mixture of oxidant and fuel for a heat engine comprising a current generator and at least one spark plug connected to said generator, said generator being adapted to generate a first signal alternating current of 1 MHz higher frequency and a second AC electrical signal of greater frequency 1 MHz.
- the system of the invention is characterized in that said generator is adapted to space in time said first and second AC electrical signals with a spacing delay and is adapted to the implementation of the method according to the invention.
- the first and second signals generated by the current generator are such that they allow the generation, via the candle thus supplied, of sparks spaced apart from each other by the predetermined spacing time delay.
- the invention also relates to a combustion engine comprising a combustion chamber and the aforementioned ignition system.
- FIG. 1 represents a view of a peak candle system according to the invention and allowing the implementation of the method according to the invention, and respective zones “a” and “b” having the zones of ignition without the method of the invention (zone “a” ) and with the method of the invention (zone “b”), the zone “b” being greater than the zone ". at ";
- FIG. 1 represents a view of a peak candle system according to the invention and allowing the implementation of the method according to the invention, and respective zones “a” and “b” having the zones of ignition without the method of the invention (zone “a” ) and with the method of the invention (zone “b”), the zone “b” being greater than the zone “. at “;
- FIG. 1 represents a view of a peak candle system according to the invention and allowing the implementation of the method according to the invention, and respective zones “a” and “b” having the zones of ignition without the method of the invention (zone “a” ) and with the method of the invention (zone “b”), the zone “b” being greater
- FIG. 2 shows a time curve of supply of the candle with the abscissa and the ordinate the intensity of the supply signal of the candle, said first and second electrical supply signals of the candle as well as the delay of spacing between these signals are shown in this Figure 2, which therefore describes the signal phasing required to implement the method of the invention
- FIG. 3 shows the detail of one of the signals represented in FIG. 2, this signal possibly being the first or the second signal because these signals are, in this particular embodiment, identical to each other;
- FIG. 4a shows a spark emitted when the spark plug receives a first high frequency power supply signal greater than 1 MHz, in this case this first signal is here 5 MHz;
- FIG. 4b shows a spark emitted when the spark plug receives a second high frequency power supply signal greater than 1 MHz, in this case this second signal is here 5 MHz, this spark of FIG. 4b is less branched than that of FIG. of Figure 4a and an amplitude and a width of spark branch greater than they are in Figure 4a;
- FIG. 5a represents the flame zone initiated by a single RF radiofrequency spark as is the case in the prior art (FIG. Aa);
- FIG. 5b represents the flame zone initiated with the method according to the invention which generates two consecutive RF radiofrequency sparks (FIG. 4b) and spaced apart with respect to time, it can be seen that this flame zone of FIG. extent than that of Figure 5a.
- the invention relates to a method for igniting a mixture of oxidant and fuel in a combustion chamber using a spark plug and the ignition system 10 for carrying out the method according to the invention and a motor including this system.
- first and second AC electrical signals 4, 5 of frequencies greater than or equal to 1 MHz for a duration of at least 150 ⁇ s, these signals being spaced apart one of the other of a delay 6 between 200 and 600 ⁇ s.
- This phasing of the signals is represented on the curve 2 where we see the first candle supply signal 4 emitted during a first step 4 followed by a delay without signal 6, itself immediately followed by a second signal 5 as emitted during the second step 5.
- curve A represents the spark temperature when the spark plug 3 is fed with only a first signal 4; and - the curve B represents the spark temperature when the spark plug 3 is fed via the second signal 5 subsequent to the first signal 6 and within a given signal spacing interval 6.
- the signal spacing delay must be adjusted during the development of the system according to the operating characteristics of the heat engine in order to adapt the nature of the spark produced to the conditions prevailing in the chamber which makes it possible to optimize the ignition conditions.
- the spacing time 6 between the first and second signals is chosen to be greater than at least once the duration of the first signal (i.e. the duration of the first step 4), in this case this spacing time 6 and here of 1500 ⁇ s is 3.3 times greater than the duration of the first signal 4 (that is to say 150 ⁇ s).
- the horizontal dotted line in FIG. 1 represents a minimum temperature threshold necessary for the ignition. In order for the mixture to ignite, this mixture must be heated by the spark at a temperature above the ignition temperature threshold.
- the possible ignition zone is of a maximum length "a" much smaller than the length "b" defining the possible area of ignition when the candle is powered with the second signal after the first.
- the ignition zone during the second signal is much greater than the ignition zone during the first signal, which makes it possible to accelerate the flame propagation speed in the chamber and to reduce unburnt and misfires.
- the mixture ignition zone 8 (8" representing the inflamed mixture volume) in the combustion chamber 2 is more extensive using the method according to the invention, with two successive high frequency spark plug power signals spaced apart from each other by a given minimum delay (Fig. 5b) as the area of ignition resulting from a single signal (Fig. 5a).
- first or second signal emitted during the first or second step 4, 5 has an alternating voltage U of candle tip (of frequency F) whose amplitude increases starting from the beginning of the supply step of candle up reach a maximum voltage.
- This first portion X of voltage amplitude increase U corresponds to the spark filament forming portion.
- this second part Y of the signal corresponds to the period of temperature rise of the filaments of the spark.
- the signal is emitted over a duration D which corresponds to the duration of the candle feeding step 3.
- these signal parameters U, F and D of each of the first and / or second signals can be predetermined depending on engine operating parameters such as the pressure P and / or the temperature T in the chamber 2 and / or the richness of the ignited mixture 8.
