Definitions

  • the utility model relates to the technical field of automobile engine ignition system, in particular to a dual-purpose automobile engine spark plug for ethanol-gasoline fuel. Background technique
  • the spark plug is widely used in the engine of a car.
  • the function of the spark plug is to discharge the pulsed high-voltage electric energy transmitted from the ignition wire, and break the air between the two electrodes of the spark plug to generate an electric spark, thereby igniting the mixed gas in the engine cylinder and pushing The piston works to make the engine run.
  • the side electrode of a normal spark plug is generally 2.8 (width) mm x 1.5mm (thickness) strip material, welded to the plug housing port by professional welding equipment, and bend the metal side electrode to the vertical position of the center electrode, and the center The electrodes form an ignition gap.
  • the purpose of the utility model is to provide a novel spark plug which is faster and better in heat conduction, can effectively protect the center electrode of the spark plug, and is less prone to ablation of the side electrode of the spark plug.
  • a dual-purpose automobile engine spark plug comprising:
  • the metal casing is located at a front end of the spark plug body, the center electrode is located in the metal casing, the insulator is located between the center electrode and the metal casing, and the side electrode is welded in front of the metal casing
  • the port side is characterized in that: the side electrode has a width of 3.0 mm and a thickness of 2.0 mm.
  • the front end surface of the metal casing is flush with the front end surface of the insulator.
  • the length of the front part of the metal casing is increased, so that the side electrode length of the engine spark plug is shortened while the ignition position of the engine spark plug is unchanged. This is more conducive to reducing the heat of the spark plug side electrode, and the heat conduction is more rapid;
  • FIG. 1 is a schematic view of a prior art engine spark plug
  • FIG. 2 is a schematic structural view of an embodiment of the present invention.
  • FIG. 1 is a schematic view showing the structure of a prior art engine spark plug.
  • the front end of the spark plug body 5 goes deep into the cylinder and is the ignition working position.
  • the outside of the center electrode 2 is an insulator 4, and the outside of the insulator 4 is a metal case 1.
  • the side electrode 3 is 2.8 mm wide and 1.5 mm thick, and the strip material is bent into an L shape and welded to one side of the front port of the metal casing 1.
  • the insulator 4 is partially exposed to the outer surface of the metal casing 1 in the axial direction.
  • the side electrode 3 is made of a strip material having a width of 3.0 mm and a thickness of 2.0 mm. Since the side electrode 3 is wider and thicker, the soldering area between the side electrode 3 and the metal case 1 is increased, which is advantageous for heat dissipation of the side electrode. As can be seen from Fig. 2, the front end face of the metal casing 1 is flush with the front end face of the insulator 4, completely wrapping the periphery of the insulator 4.
  • the length of the spark plug metal casing 1 can be lengthened by about 1 mm compared with the metal casing of the ordinary spark plug without changing the length of the spark plug body.
  • the advantage of this change is that the length of the metal casing 1 is lengthened, which enables The length of the side electrode 3 is correspondingly reduced by about 1 mm, thereby reducing the amount of heat received by the side electrode.
  • the front end face of the metal casing 1 is flush with the front end face of the insulator 4 outside the center electrode 2, so that the spark plug insulator 4 is protected by the metal casing 1, and can withstand higher temperatures, thereby better protecting the center electrode 2.
