The utlity model has following advantage:
1, because the utility model arranges 2 or more central electrode and corresponding lateral electrode, " the single-point igniting " of a central electrode and a lateral electrode in the past of therefore comparing, the utility model has increased ignition gap.Because each central electrode connects the high-voltage line of different circuit respectively, the bridge connected multicenter electrode of comparing and only connecting a high-tension circuit in the past, the reliability of ignition energy and the stability of while multi-point spark have been guaranteed, realized that multi-electrode truly lights a fire simultaneously, effectively enlarged the discharge igniting sphere of action, make the cylinder mixture combustion more abundant, reach the good result of oil-saving discharging-reducing and lifting automobile power.
2, in present automotive ignition system, what spark plug and high pressure electric conductor all adopted is the connected mode of pegging graft, and namely central electrode (discharge electrode bar) is inserted in the high-voltage line terminal by conducting rod or connects conduction in the coil tension spring of ignition coil electric conductor.The input of the utility model conducting rod electric current is provided with external screw thread, and the mode of taking to be spirally connected is connected conduction with the high-voltage line terminal of ignition coil, thereby connects firm stable more.
3, the utility model is the compact spark plug, takes the ultra-fine high pressure resistant line of high-quality.Form with welding between each conducting rod and the corresponding discharge electrode bar is connected, each conducting rod connects the high-voltage line terminal in the mode of being spirally connected, thereby solved in the cylinder block small space difficulty that a spark plug connects two high-voltage lines, made free-standing ignition coil function further be improved and improve.
4. separate between the discharge end that collets make the first and second discharge electrode bars and realize electrical isolation.The discharge spacing between each discharge electrode bar and the corresponding lateral electrode has been dwindled in the setting of the first discharge projection and the second discharge projection, has reduced the required energy of discharge igniting, has improved each discharge igniting success rate.
In a word, the utility model is easy to be connected with the automobile high-voltage line, and it is stable to be connected firmly, the real multi-electrode of having realized that arranges of a plurality of discharge electrode bars is lighted a fire simultaneously, effectively enlarged the discharge igniting sphere of action, make the cylinder mixture combustion more abundant, can reach the good result of oil-saving discharging-reducing and lifting automobile power.
