摘要： Carbon fouling adhered on an insulator tip of a spark plug of the present invention is burnt down by a leak current during an inductive discharge period, due to a promoted ionization before beginning a capacitive discharge, in such an arrangement of a central electrode that a border portion of a body and narrowed portion is positioned in an insulator. The carbon burning-down effect is further improved by a narrow projection provided with an earth electrode, due to increased inductive energy and extended inductive discharge time period. This is because an electric field in a discharge gap is raised, thereby decreasing a discharge voltage and suppressing an energy emitted from a coil during the capacitive discharge.

摘要： A spark plug for internal-combustion engines includes a housing, an insulator, a center electrode, and an earth electrode. A gas guiding sections equipped with slopes that slope inwardly as they approach toward a tip side from a circumference surface of the housing and guide surfaces that are disposed on both sides in a circumferential direction of the slopes are formed in a tip part of the housing. The gas guiding sections are formed in the circumferential direction within a 90-degree range measured relative to the center of the earth joint section, which is a junction of the housing and the earth electrode, in the circumferential direction. When the spark plug is mounted to the engine, it is constituted so that the gas guiding sections are projected into a combustion chamber.

摘要： A spark plug for an internal combustion engine is provided which is equipped with a tip protrusion disposed on a top of a hollow cylindrical housing of the spark plug. The spark plug also includes a center electrode retained in a porcelain insulator disposed inside the housing and a ground electrode is joined to the housing so as to form a spark gap. The tip protrusion serves to direct a flow of gas to be ignited by a spark produced in the spark gap and is shaped to have a radial width extending in a radial direction of the housing and a circumferential width extending in a circumferential direction of the cylindrical housing. The radial width is greater than the circumferential width. This enhances the efficiency in guiding the flow of gas toward the spark gap.
