Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
A kind of bulky capacitor formula fire rod shown in composition graphs 1-Fig. 5, comprise metal housing 1, spark plug 2 and high-pressure connection line 4 is provided with in described metal housing 1, described spark plug 2 is connected by connector 5 with described high-pressure connection line 4, described high-pressure connection line 4 from inside to outside comprises copper core 41, insulating barrier 42 and metal level 43 successively, elastic sheet metal 6 is provided with between described metal housing 1 and described high-pressure connection line 4, described elastic sheet metal 6 one end contacts with described metal housing 1, and the other end contacts with described high-pressure connection line 4.
In the present embodiment, described metal housing 1 cylindrically.
In the present embodiment, described spark plug 2 is closed spark plug.
In the present embodiment, the wiring screw rod of described spark plug 2 is arranged along the axis of described metal housing 1.
In the present embodiment, between described metal housing 1 and described high-pressure connection line 4, be provided with insulating positioning sleeve 7 and lining 3.
In the present embodiment, described elastic sheet metal 6 is inserted between described insulating positioning sleeve 7 and described lining 3.
The wiring screw rod of the spark plug 2 coaxially arranged and high-pressure connection line 4 are connected into a conductive path by connector 5 by the present invention, the other end of high-pressure connection line 4 is made into the terminals 8 with certain profile makes it be connected with high-tension coil, then by physical weld mode, the metal housing 1 of a drum type brake is welded on outside spark plug 2 axis, the inner HTHP insulating positioning sleeve 7 that passes through is by positioned apart to high-pressure connection line 4 and metal housing 1, so just can form a Unified Global, high-tension electricity is introduced from high-pressure connection line 4 and is flowed into spark plug 2 firing tip connected along high-pressure connection line 4, the gap that spark plug 2 firing tip is formed makes gas therebetween that the final air mixture producing spark ignition periphery of ionization occur, blast.
High-pressure connection line 4 in the present invention adopts net cored structure, the copper core 41 that the inside adopts electric conductivity excellent, centre adopts the insulating barrier 42 of insulation property superelevation and ensures that its thickness is in the scope of safety, layer of metal material is then covered at the skin of insulating barrier 42, except high-pressure connection line 4 connector approach end except other wire positions can covering metal layer 43, and this layer of metal level 43 will have certain pliability, then adopt elastic sheet metal 6 that the metal level 43 outside high-pressure connection line 4 is linked to be an entirety with metal housing 1.
Be illustrated in figure 3 cylinder inner carrier force diagram.
Be in the compression stroke in four-stroke-cycle in figure, piston upwards, combustion gas is compressed continuously, and before arrival top dead centre, cylinder internal gas pressure P constantly becomes large.
When fire rod is constant with other conditions (ignition gap), the dielectric dielectric constant of ε is larger, and it is larger that igniting punctures required voltage; And the factor that ε changes in cylinder depends on cylinder pressure P and temperature T, and ε and P direct proportionality; And P cylinder pressure increases along with the reduction of β angle.
In generating set, ignition advance angle β can not artificially arbitrarily change, and is a parameter of relatively fixing.
And present invention employs outer metal level 43 structure of high-pressure connection line 4, and metal level 43 is connected with the metal housing 1 of fire rod, such people is the electric capacity C substantially increasing fire rod itself, in the ignition circuit, electric current flows into fire rod by ignition coil, and the change curve of ignition voltage is similar to sine curve, in such LRC circuit, the change of voltage progressively promotes.
Be illustrated in figure 4 the change curve of ignition voltage in the cycle in firing circuit.
Be illustrated in figure 5 the charge graph of RC.
In figure when voltage is in Uj, there is arcing; Dotted line is ignition coil theoretical voltage change curve, and the existence due to electric capacity causes the change of time shaft lower part.
τ＝R·C………………(1)
Wherein: τ---time constant;
U
0---terminal voltage;
From (1), (2) two formulas: the value of capacitor C is larger, then timeconstantτ is also larger, and thereupon
less; When
less, then
otherwise it is larger.Wherein t, τ are greater than zero all the time, therefore known:
Therefore, at a time during t, when the value of capacitor is larger, then the magnitude of voltage that two ends can be made to produce is also larger (more close to U
0value), in other words, voltage can be regarded as and arrive the time shorten of demand.
When arriving ignition advance angle, circuit starts to charge to fire rod, and the electric capacity of the fire rod of the present invention's design significantly promotes, so just there is the time point of igniting in advance than normal fire rod, and the air pressure P of the time cylinder shifted to an earlier date is just little than the fire rod P not having the present invention's design relatively lagged behind, P is little for cylinder pressure, and the dielectric dielectric constant of ε diminishes, and during igniting, the voltage of demand is just relatively little like this.
Therefore, the fire rod of the present invention's design just has and reduces the effect of ignition voltage, and the reduction of ignition voltage, and the fault of to carry out unit maintenance as the differentiation of unit data because of sparking voltage just will reduce greatly, improve the useful life of fire rod simultaneously; And because bulky capacitor introduces firing circuit, electric capacity itself has certain energy storage effect, like this when arriving fired state, more electric energy just can be provided in circuit for puncturing fuel gas mixture, so also will be beneficial to the Thorough combustion of fuel gas mixture, thus improve power output and reduce discharge.
The present invention can reduce demand point ignition voltage during igniting, effectively shortens the duration of ignition, shortens burning time, improves fuel economy and dynamic property and emissions reduction effectively.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement etc., all should be included within protection scope of the present invention.
