Abstract:
A spark plug includes a main ground electrode having a main connecting portion connected to the housing and forming a discharge gap between the main ground electrode and the center electrode, and a sub ground electrode having a sub connecting portion connected to the housing. The direction on which the main connecting portion and a plug center axis are arranged is set to be perpendicular to an air flow direction of an air stream in the combustion chamber. The sub connecting portion is located in a downstream side than the main connecting portion. The tip end position of the sub ground electrode in the plug axial direction is located in farther tip end side than that of the main ground electrode is. The sub ground electrode is configured such that an end point of the discharge spark is movable on the sub ground electrode.

Claim (Index 1):
A spark plug of an internal combustion engine, the spark plug capable of being attached to the internal combustion engine having a combustion chamber, producing a discharge spark in the combustion chamber, the spark plug comprising:\n a housing having a cylindrical shape; an insulator supported inside the housing; a center electrode supported inside the insulator; a main ground electrode having a main connecting portion connected to the housing and forming a discharge gap between the main ground electrode and the center electrode; and a sub ground electrode having a sub connecting portion connected to the housing at a portion different from the main connecting portion in a circumferential direction of the spark plug, wherein a direction on which the main connecting portion and a plug center axis are arranged is set to be perpendicular to an air flow direction of an air stream in the combustion chamber, when viewed from a plug axial direction; the sub connecting portion is located in a downstream side of the air stream in the combustion chamber than a position of the main connecting portion is; a tip end position of the sub ground electrode in the plug axial direction is located in farther tip end side than a tip end position of the main ground electrode in the plug axial direction is; and the sub ground electrode is configured such that an end point of the discharge spark is movable on the sub ground electrode, when the end point of the discharge spark produced in the discharge gap moves to the sub ground electrode from the main ground electrode.
