Specific embodiment
The following describes the present invention in detail with reference to the accompanying drawings and embodiments.
Referring to Fig.2, the automobile-used igniter includes a control electricity for one embodiment of the automobile-used igniter of the present invention
2, one, source cap unit 3 and a cigar lighter 4.
The control power supply 2 is controlled to be converted between a power supply state and an off-position.
In the present embodiment, the cap unit 3 include one cap shell 31, one be set in the cap shell 31 and
The first conduct piece 32, one for being electrically connected the control power supply 2 is set in the cap shell 31 and is electrically connected first conduct piece
Elastic component 33, one of 32, which are set to, in the cap shell 31 and to be electrically connected resistance unit 34, one of the elastic component 33 and is set to
In the cap shell 31 and it is electrically connected the second conduct piece 35 of the resistance unit 34 and one is set in the cap shell 31 and sets
It is placed in the magnetic force piece 36 of the outer peripheral surface 351 of second conduct piece 35.
It is noted that the elastic component 33 is also possible to be electrically connected to the resistance in other change case of the present embodiment
Between part 34 and second conduct piece 35.In addition, in other change case of the present embodiment, the resistance unit 34 can also regard demand and
Be not provided with, that is, the cap unit 3 only include the cap shell 31, first conduct piece 32, the elastic component 33 and this second
Conduct piece 35.In the present embodiment, which is a helical spring, but not limited to this.
The magnetic force piece 36 has an a north-seeking pole N and south pole S.In the present embodiment, which surrounds and sets
It is placed in the outer peripheral surface 351 of second conduct piece 35, and the inner peripheral surface with an outer peripheral surface 351 towards second conduct piece 35
361.The inner peripheral surface 361, which surrounds, defines the perforation 362 worn for second conduct piece 35, the inner peripheral surface 361 and this
The outer peripheral surface 351 of two conduct pieces 35 abuts each other.In addition, the magnetic force piece 36 is neodymium iron boron (NdFeB) magnet or one
Ferrite (ferrite) magnet, but not limited to this.
The cigar lighter 4 is electrically connected second conduct piece 35, and the middle electrocardio of second conduct piece 35 is electrically connected including one
Pole 41 and one and the central electrode 41 with a gap apart from one another by grounding electrode 42.The gap has a gap electricity
Press Vgap。
The north-seeking pole N of the magnetic force piece 36 is towards the direction of the cigar lighter 4.
When the control power supply 2 is in the power supply state, gap voltage VgapThe electric field strength of offer is very high, it is sufficient to cause
Electrical breakdown, so the cigar lighter 4 can generate electric arc.When the control power supply 2 is in the off-position, gap voltage VgapInstitute's energy
The electric field strength of offer is minimum, is far not enough to cause electrical breakdown, so the cigar lighter 4 will not generate electric arc.
Refering to Fig. 3, the schematic illustration of peak value gap voltage is promoted for the automobile-used igniter of the present invention.When the gap voltage
VgapElectric field E cause electrical breakdown and generate moment of electric arc, a large amount of free electron e-Plasma-based is passed through by the grounding electrode 42
Dielectric (see Fig. 2), and sequentially along the central electrode 41, second conduct piece 35, the resistance unit 34, the elastic component 33,
The path of first conduct piece 32 is mobile towards the control power supply 2 and forms electric current.
At this point, the magnetic force piece 36 in the centre of second conduct piece 35 with high-intensitive magnetic field B along the side of electric current
To acting on free electron e-(a free electron e is only drawn in figure-As signal), make by second conduct piece 35 from
By electronics e-Accelerate to advance with spiral path, forms the effect of similar pumping, it is related so that the grounding electrode 42 is forced supplement more
More free electron e-To the central electrode 41, thus the current value for making electric arc form moment is substantially improved, and adds the resistance
Part 34 have fixed resistance value (such as: 3k Ω), so that gap voltage VgapMaximum value can with electric arc formed wink
Between current value improve and synchronize appearance significantly promoted.
Refering to Fig. 4, waveform 91 is gap voltage V of the automobile-used igniter of the present invention before and after electric arc generationgapAt any time
Variation, the magnetic force piece 36 are using ndfeb magnet；Between waveform 92 is the automobile-used igniter of the present invention before and after the electric arc generation
Gap voltage VgapIt changes with time, which is using ferrite lattice；Waveform 93 is existing igniter in electric arc
Generate the gap voltage V of front and backgapIt changes with time.
As shown in figure 4, the peak value gap voltage of waveform 91, waveform 92 and waveform 93 be respectively 316kV, 222kV and
148kV, and the time that peak value gap voltage occurs then is respectively 11ns, 25ns and 25ns, it is known that the automobile-used igniter of the present invention
Peak value gap electricity when using ndfeb magnet, compared to existing igniter, in addition to one times (113.5%) can be lifted beyond
Other than pressure, moreover it is possible to electric arc be allowed to generate (shorten to 11ns by 25ns) within the shorter time.
Finally, detection is exhausted in the automobile-used igniter of the installation present invention and existing igniter respectively, detect herein
The magnetic force piece 36 of middle automobile-used igniter of the invention is ndfeb magnet, and the result for being vented detection is as shown in the table:
From the foregoing, it will be observed that the present invention, compared to existing igniter, toxic CO emission reduces one third,
The not burned hydrocarbon (hydrocarbon, HC) utilized reduces by more than half, and the carbon dioxide (CO being discharged2) then
It is relative increase, indicates that the degree of fuel completely burned is higher.
It is summarized as follows via above explanation, then by advantages of the present invention:
One, the present invention can be produced using the magnetic force piece 36 for the outer peripheral surface 351 for being compassingly set at second conduct piece 35 in electric arc
Raw moment enables the free electron e for constituting electric current by the effect of the magnetic field B of the magnetic force piece 36-Continue the side accelerated with spiral
Formula forms the effect of similar pumping, compared to existing igniter, the present invention can break through the control by second conduct piece 35
Power supply 2 processed supplies the limitation of voltage, and peak value gap voltage is substantially improved in the moment that electric arc generates, thus can with more rapidly and
More stable electric arc removes to light the fuel in engine cylinder, achievees the purpose that completely burned, is further reduced the row of pernicious gas
The utilization rate put and promote fuel.
Two, the present invention improves peak value gap voltage when electric arc generates using the magnetic force piece 36, compared to existing igniting
Device, the present invention in vehicle when route is old to lead to the supply voltage of the control power supply 2 lower than rated value, remain to effectively and
Stable electric arc is quickly generated, the situation for avoiding vehicle from stopping working or can not start in traveling.
Three, the present invention by the magnetic force piece 36 using the stronger ndfeb magnet of magnetic force, compared to using ferrite
Magnet, which makes peak value gap voltage have significantly more promotion using ndfeb magnet, while also allowing electric arc more
It is generated in the short time, so the oil gas that can ignite moment, and in a manner of explosion engine pistons are carried out with powerful acting.
In conclusion the automobile-used igniter of the present invention can not only promote peak under conditions of not changing original supply voltage
It is worth gap voltage, moreover it is possible to quick and stable electric arc is provided and remove to light fuel in engine, so can reach really of the invention
Purpose.
As described above, only the embodiment of the present invention is when cannot be limited the scope of implementation of the present invention with this, i.e., all
According to simple equivalent changes and modifications made by claims of the present invention and description, all still belong to the scope of the present invention.
