Definitions

  • This invention relates to a spark plug, particularly, a spark plug with a ring-shaped ground electrode.
  • the ground electrode 9 under the center electrode 8 is a rectangular piece; between the two electrodes, there is a spark gap 10.
  • a rectangle-ahaped discharge 11 will take place.
  • the discharging surface of the ground electrode will be coated with carbonized deposits, and this is particularly true to the two-stroke engine.
  • the electrodes near the spark gap are coated with some granular carbonized deposits, which may result in engine failure or engine unable to start; all these troubles would put the user to inconvenience.
  • the prime object of the present invention is to provide a spark plug with a ring-shaped ground electrode to generate a slope type of discharging spark. Since the ground electrode forma a round frame over the center electrode, there will, upon explosion taking place, be a high speed air stream to pass through the gap between the electrodes to clean the carbonized deposits off out of the round frame, i.e., something like a washing effect to prevent from generating granular carbonized deposits.
  • the prime feature of the present invention is the round frame on the ground electrode; the round frame has a gap, and the inner diameter of the round frame ia longer than that of the center electrode so as to generate a slope type of discharging spark.
  • a conventional spark plug which mainly comprises a center electrode 8 and a ground electrode 9.
  • the center electrode 8 is surrounded with insulator 2 with filling stuffs 3 therein.
  • the top is provided with a terminal 1; outside the insulator 2, there is mounted a ground electrode 9, which extends under the tip of the center electrode 8 with a given spark gap 10.
  • the bottom end of the center electrode 8 is a flat and smooth surface 12 without any crossed threads.
  • the ground electrode 9 is a solid piece, a carbonized deposit as a result of sparking is usually deposited on the discharging surface of the ground electrode 9; that deposita may cause abnormal ignition.
  • Fig. 3 and 4 there is shown the ring-shaped ground electrode and the canter electrode of the present invention, in which the bottom end of the center electrode 21 ie provided with crossed threads 23, while the end of the ground electrode 22 is designed into a round frame 24 with a gap 25 to open a portion of the round frame that is opposite to the ground electrode 22.
  • the inner diameter of the round frame 24 is longer than that of the center electrode 21.
  • the gap 25 is used for preventing the temperature of the ground electrode 22 from being into focus to form a blockade to temperature circulation so as to have the high temperature of the ground electrode transmitted to a radiator promptly.
  • FIG. 5 there is shown another embodiment of the present invention, which includes a center electrode 31 and a ground electrode 33 with crossed threads 32, but the inner periphery of the round frame of ground electrode 33 in provided with a number saw teeth 34.
  • FIG. 6 there is shown a still another embodiment of the present invention, which includes a center electrode 41 with crossed threads 42 on top, and a ground electrode 43 furnished with several salient lugs 44 along the inner periphery of the round-frame.
  • the improved portion of a spark plug in the present invention is merely limited to the ground electrode, but that limited improvement will surely solve the carbonized deposit problem to an expected extent, i.e., it is deemed as being an advanced and practical spark plug without doubt. Since there has been no similar product being found in some relative information and in the markets both domestically and abroad, its novelty may conform with the requirments of the patent law.
