In the spark plug, the ground electrode is fixed to a mount fitting, while the ground electrode has a convex portion. The convex portion is made of a part of base materials of the ground electrode where the part is facing the center electrode, and is projected toward the center electrode. The convex portion has a fusion solidification part made of precious metal materials and a part of the base materials melted together and solidified at least on part of an electric discharge surface facing the center electrode.

摘要： A method of manufacturing a spark plug having an attachment fitting 2, an insulator 3, a center electrode 4 and an earth electrode 5. While fixed to attachment fitting 2, earth electrode 5 has a convex part 510 formed by projecting a part of an opposed surface 51 toward center electrode 4, and a concave part 520 formed toward the opposed surface 51 from the earth electrode's back surface 52. The convex part 510 is disposed so that the extension of a shaft center of the convex part 510 passes through the area in which the concave part 520 is formed. The relation S1>=s is realized when an area of an opening of the concave part 520 is set to S1 and an average cross-section area of a cross section of the convex part 510 perpendicular to an axial direction of the spark plug is set to s.

摘要： A spark plug for an internal combustion engine is provided which includes a hollow cylindrical metal shell with an open end portion to be exposed to a combustion chamber of the engine, a ground electrode joined to the metal shell, a center electrode disposed in the metal housing to define a spark gap between itself and the ground electrode. The spark plug also includes a stream shaper geometrically formed on an outer periphery of the open end portion of the metal shell to shape tumble vortexes of air-fuel mixture into vortex streams oriented toward a central portion of the combustion chamber. This ensures the stability of orientation of the tumble vortexes to control a flow of sparks, thereby enhancing the ignitability of the air-fuel mixture in the combustion chamber.

摘要： A spark plug according to the present invention includes a metal shell, an insulator retained in the metal shell, a center electrode secured in the insulator, and a ground electrode. The center electrode includes a base member and a thin member thinner the base member. The ground electrode includes a base member fixed to the metal shell and a protruding member that protrudes from the base member and has an end face with an inner and an outer edge. When the insulator is clean, sparks can be discharged between the thin member and the inner edge. When the insulator is fouled with carbon, sparks can be discharged between the base member and the outer edge to self-clean the insulator. Dimensional parameters and relationships are specified in the spark plug, so that the spark plug can induce spark discharges with a low discharge voltage while securing an excellent self-cleaning capability thereof.

摘要： A spark plug includes a metal shell, an insulator, a center electrode, and a ground electrode. The ground electrode includes an intermediate portion extending in the axial direction of the center electrode in an axial range between an end of the insulator and an end of the center electrode. The intermediate portion has a thickness surface that is perpendicular to a radial direction of the center electrode and defines a thickness of the intermediate portion in a thicknesswise direction that is perpendicular to both the axial and radial directions of the center electrode. The intermediate portion also has a width surface that is perpendicular to the thickness surface and defines a width of the intermediate portion in a widthwise direction that is perpendicular to both the thicknesswise direction and the axial direction of the center electrode. The thickness of the intermediate portion is smaller than the width of the same.
