Abstract
This invention relates to a piston gas oil diesel spare part composed of a ball nut, a conduction screw rod, an insulating porcelain, an iron shell, a side electrode, a crossover electrode and a central electrode characterizing in moving the central electrode from the position of the traditional porcelain central axis to outside so as to increase the distance between the side electrode and the central electrode to relatively increase the sparking distances between the central and the crossover electrodes and the sparking distance between the crossover and the side electrodes to further strengthen the sparking energy, in which, the oil mixed gas can burn completely to increase the power of the engine.
Description
Technical field:
What the present invention relates to is piston type gasoline internal combustion machine part, especially a kind of eccentric string polar spark plug.
Background technology:
In the prior art, technique known is the applicant's No. 96228846.2 patents, this patent disclosure a kind of technical scheme of cascade high-energy sparking-plug, the arcing gap of the comparable common spark plug of spark plug of this scheme increases 2-3 doubly, has improved ignition energy greatly.But the spark plug of this structure, the axis of its central electrode and the axis of insulating ceramic are coaxial, this just limited between central electrode and the lateral electrode apart from l, also just limited central electrode and crossed over beeline l between the electrode
1And the beeline l between leap electrode and the lateral electrode
2, because the arcing length overall of spark plug is l
1+ l
2, in order to ensure the arcing spark at l
1And l
2In carry out, just must accomplish (l
1+ l
2)＜l.Because there is strict unified standard in the diameter of thread country of spark plug, equaling the screw thread inside radius apart from l and subtract the central electrode radius between lateral electrode and the central electrode, it is exactly the limiting value in this spark plug sparking gap, therefore, the structure that increases the existing spark plug of arcing gap and ignition energy can not adapt to, and this is the existing in prior technology weak point.
Summary of the invention:
Purpose of the present invention is exactly at the existing in prior technology deficiency, and the technical scheme that provides a kind of off-centre to go here and there polar spark plug, this scheme adopts the structure of central electrode axis runout insulating ceramic axis to reach the distance that increases between central electrode and the lateral electrode, improves arcing gap and ignition energy.
This programme is realized by following technical measures: it is made up of bulb nut, conductive lever, insulating ceramic, iron-clad housing, lateral electrode, leap electrode and central electrode, the characteristics of this programme are the position of axis beyond the insulating ceramic central axis of described central electrode, this position is parallel to outer displacement by the geometrical central axis line position of insulating ceramic, displacement limitation will be with the insulating ceramic thickness 〉=1.5mm of central electrode direction of displacement.The concrete characteristics of this programme also have, and described central electrode and conductive lever are that the end face butt welding becomes an electric conductor, and two circumference of butt welding solder side must be a bit to overlap.Described central electrode, lateral electrode and leap electrode are the cylinders that axis is parallel to each other.
The beneficial effect of this programme can be learnt according to the narration to such scheme, because in this scheme, the central electrode axis shifts out the axis of insulating ceramic, has increased the distance between central electrode and the lateral electrode, can obtain sparking distance and the ignition energy bigger than prior art.Test by experiment, this programme can make generator power improve 12%-18%, make the automobile F-Zero improve 10%-15%, hydrocarbon can be reduced to 300mmp by 1700mmp in the tail gas, carbon monoxide content can drop to 0.2% from 4.5%, and can reach the oil-saving effect of 15%-25%, automotive performance is obviously improved.This shows that the present invention compared with prior art has outstanding substantive distinguishing features and obvious improvement, the beneficial effect of its enforcement also is conspicuous.
Description of drawings:
Fig. 1 is the sectional structure schematic diagram of the specific embodiment of the invention.
Fig. 2 is the sectional structure schematic diagram of prior art.
Among the figure, 1 is the bulb nut, and 2 is conductive lever, and 3 is insulating ceramic, and 4 is the iron-clad housing, and 5 is lateral electrode, and 6 for crossing over electrode, and 7 is central electrode.
Embodiment:
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by an embodiment.
By accompanying drawing as can be seen, the off-centre string polar spark plug of this programme is made up of bulb nut 1, conductive lever 2, insulating ceramic 3, iron-clad housing 4, lateral electrode 5, leap electrode 6 and central electrode 7, the position of the axis of described central electrode 7 beyond insulating ceramic 3 central axis, this position is parallel to outer displacement by the geometrical central axis line position of insulating ceramic 3, displacement limitation, will be with the insulating ceramic 3 thickness 〉=1.5mm of central electrode 7 direction of displacement, the porcelain body thickness of 1.5mm is to puncture minimum insurance thickness.Described central electrode 7 is that the end face butt welding becomes an electric conductor with conductive lever 2, and two circumference of butt welding solder side must be a bit to overlap, and that is to say that it is on same straight line that the bus of the bus of central electrode 7 and conductive lever 2 has only a bus.Described central electrode 7, lateral electrode 5 and leap electrode 6 are cylinders that axis is parallel to each other.
