摘要： A spark plug includes a tubular metal shell, an insulator, a cylindrical center electrode, and a ground electrode. The ground electrode has an inclined portion, a straight portion, and a bend between the inclined and straight portions. The inclined portion extends obliquely with respect to the axial direction of the center electrode from a base end of the ground electrode, which is joined to an end of the metal shell, to the bend that is positioned closer to the center electrode in the radial direction of the center electrode than the base end. The straight portion extends substantially parallel to the axial direction of the center electrode from the bend to a tip end of the ground electrode. The straight portion has an inner side surface facing the side surface of an end portion of the center electrode through a spark gap in the radial direction of the center electrode.

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 inner 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： There is provided a spark plug that includes a center electrode, an insulator, a housing, a ground electrode, an auxiliary ground electrode, and a projected portion in the housing. The housing has a though-hole which is formed in the housing along the longitudinal axis of the center electrode and has an opening of the through-hole at the first housing end. The ground electrode has a first end facing the end of the center electrode to form a first discharge gap. The auxiliary ground electrode has a first end facing an outer peripheral surface of the first end of the insulator to form a second discharge gap. The projected portion is formed in a hollow portion of the through-hole and is projected from an inner peripheral surface of the hollow portion of the housing.

The spark plug also includes a stream shaper or a stream reflector geometrically formed on the metal shell and/or the porcelain insulator to shape a vortex steam of air-fuel mixture into a stream thereof which is oriented outside the spark plug or serves to decrease the amount of the air-fuel mixture into a pocket between the metal shell and the porcelain insulator. This ensures the stability of ignition of the air-fuel mixture.
