matches, and can have little range of activity such as 0.1mm up and down, and meanwhile, particularly arc drum 24a is recessed with respect to arc 25a can rotate, so the recessed rotation of arc drum is more preferred than the screw thread of original part or screw thread shape groove, therefore its fine setting during arcing And the trend of carbon deposition removal is more excellent；The place puncturing under first during electric discharge, at second time and be next still the position easily hit, by Particularly rotate in the shake of electrode and fine motion, for the place that two electrode last time punctured relatively, relatively-stationary electric discharge Place turns to unfixing and avoids, so that the local displacement of multiple discharge, and discharge each time and just have electrode molecule to be translated into Gaseous state and be lost, therefore its usefulness is self-evident, extends the life-span of electrode and is beneficial to carbon deposition removal.The shake of electrode and Fine motion particularly rotates, and is easy acquisition under the vibration condition in kinetic energy engine.Due to described electric discharge cartridge 11 be subject to The inside of electrode tip 24, is analogous to by electrode tip 12, constitutes discharging gap by the basin shape of top and ring sidepiece, and have at top many The individual wedge

characterized in that being provided with least one in described ring sidepiece, or 2, or multiple, particularly 6 insertions Opening, is conducive to flowing and the discharge carbon deposit of gaseous mixture, and particularly rotates the additional air-flow of offer to shake and fine motion.Because The feature of the described wedge 11b of electric discharge cartridge 11 is that end is provided with the polygonal pyramid digging out thereon, particularly criss-cross many ribs Cone, therefore be conducive to the edgetone effect of ion stream of lighting a fire；Make in the basin shape gap containing top surface and ring side of spark plug, especially office Portion increased the gap of polygonal pyramid, makes the position part that fiery karyomorphism becomes leave wall, has buffer cells, can avoid stagnating In the impact of near wall residual gas, meanwhile, coordinate the many sideshakes 24b setting up, particularly arc drum 24a is with respect to arc The rotation of recessed 25a, is conducive to the wedge of gaseous mixture to collide and turbulence effect, adds electric discharge cartridge 11 and the fine motion by electrode tip 24 With effect of trembling, the absolute quantities of the gaseous mixture in gap are made to increase, the probability catching fire also increases, in addition, wedge collides and disorderly The part that stream is also beneficial to repel in carbon deposit molecular flow, wedge and in basin shape gap has the mixture of liquefaction tendency, not only has electricity The opportunity of arc discharge, and have the cydariform electric discharge of similar spark machined electric discharge, thus, its resultant effect makes spark discharge quality Improve, performance of operating condition is more preferably.The criss-cross polygonal pyramid of the described wedge 11b of electric discharge cartridge 11, can be utilized to put stubborn spiral shell The instrument of silk, makes the screw thread of wedge 11b or screw thread shape groove 11c match with electric discharge pole bar 9.Described by electrode tip 12 and be subject to electrode 24 cross, also can be utilized to put the instrument of the turn of the screw.The side flabellum 11a of described electric discharge cartridge 11 has complementary Micro- transferring to is used and complementary discharge process.This electrode is suitably arranged in pairs or groups with the waveform piston having spark pit 36.Spark pit 36 increases Big seed region, air inlet pit 33 increases air inlet flowing, and aerofluxuss pit 33 has squish to act on, and function wave helps deflagration wave and disseminates.

Because described multiple improvement are available for various types selecting, and when on probation, also can correct advance angle and regulation and control high-tension pulse Rush parameter in the hope of more preferably.In addition the special improvement 7 proposing, is to make the positive and negative commutation of high electric field pulse and change direction, also can try out.Though So spark-ignition process is extremely complex, and the mankind still have many aspects not clear so far, but it is understood that electricity positive and negative to putting Electrode and the loss by electrode have Different Effects.Improving 7 is a kind of method for reducing export license, is just to make voltage x current Negative commutation, this is not difficult to realize with electromagnetism class and electrical type circuit, for example, use astatic multivibrator and peaker；Commutate is secondary Number or synchronous with engine speed, or interval, or it is spaced the commutation of some periods, it is worth improving further.Described various improvement, All be conducive to increasing the probability of electric discharge and remove carbon deposit and reduce export license, in practicality or special according to different types It is to select after the angle of ignition carrys out pilot, and arrange in pairs or groups with the combustor having function wave of improvement.
