Abstract:
A spark plug for an internal combustion engine is provided which has a center electrode and a ground electrode. The ground electrode includes an upright portion extending in a lengthwise direction of the spark plug and an extension bent from the upright portion in a radial direction of the spark plug. The extension has a slant surface which is shaped to be inclined away from the center electrode downstream in a flow of air-fuel mixture within a combustion chamber when the spark plug is mounted in the engine. This results in an increase in in distance by which a starting point on the ground electrode where a spark is created is moved on the slant surface, thereby increasing a length of time the spark is moved downstream and then blown out to increase the probability of successful ignition of the air-fuel mixture.

Claim (Index 1):
A spark plug for an internal combustion engine comprising:\n a hollow cylindrical housing; a hollow cylindrical porcelain insulator which is retained inside the housing; a center electrode which is retained inside the porcelain insulator with a top portion thereof protruding outside the porcelain insulator; and a ground electrode which defines a spark gap between itself and the center electrode, wherein the ground electrode includes an upright portion which extends from a front end of the housing to a front side of the spark plug and an extension which is bent from the upright portion inwardly in a radial direction of the spark plug, wherein if a direction which is oriented perpendicular both to an extension lengthwise direction that is a lengthwise direction of the extension and to a plug axial direction that is an axial direction of the spark plug is defined as a lateral direction, and sides opposed to each other in the lateral direction are defined as a Y 1  side and a Y 2  side, respectively, the extension has an inner slant portion which faces the center electrode and is inclined away from the center electrode from the Y 1  side to the Y 2  side, and wherein the extension has a first and a second edge which are opposed to each other in the lateral direction, and the inner slant portion continuously extends from the first edge to the second edge of the extension.
