摘要： The present disclosure generally relates to an ignition plug tip (70) of an ignition plug configured to be used in an internal combustion engine including at least one main combustion chamber. The disclosed ignition plug tip (70) may comprise a nozzle portion (74) forming at least a portion of a pre-combustion chamber (66) and having an inner surface (75). The disclosed ignition plug tip (70) may further comprise at least one flow channel (110) configured to fluidly connect the pre-combustion chamber to the main combustion chamber, wherein the at least one flow channel (110) includes a main portion (118) having constant cross-section and a funnel-shaped inlet portion (114) at the inner surface (75). The inlet portion (114) may constitute about 30% to 70% of the length of the flow channel (110).

摘要： The objective of the present invention is to improve the heat conductance of the center electrode of the spark plug in which its center electrode protrudes to the combustion chamber from the defining surface of the chamber. The ignition plug of the present invention comprises a center electrode to where high voltage for spark discharge is applied; an insulator having a penetration hole to where the center electrode is fit; and an earth electrode that forms a discharge gap between the center electrode at where the spark discharge is generated. The center electrode protrudes from a defining surface of an internal combustion engine to a combustion chamber when the ignition plug is attached to the engine. The entirety of a main body of the center electrodes that is fixed by fitting into a penetration hole of the insulator is made of high heat conductance material having heat-conductivity of 250 W / mK or more.

摘要： An ignition plug (1) includes a center electrode (5) extending in the direction of an axis (CL1), an insulator (2) having an axial hole (4) into which the center electrode (5) is inserted, a tip (31) joined to a forward end portion of the center electrode (5) by a fusion portion (35), and a ground electrode (27) forming a gap (33) in cooperation with the tip (31). The ignition plug generates high-frequency plasma at the gap (33) when high-frequency electric power is supplied to the gap (33). The forward end of the tip (31) is located forward of the forward end of the insulator (2) with respect to the direction of the axis (CL1). Also, at least a portion of the outer surface of the fusion portion (35) is located within the axial hole (4), and, the distance between a forward-end-side opening of the axial hole (4) and the rearmost end of the outer surface of the fusion portion (35), measured along the axis (CL1), is equal to or greater than 0.1 mm. Thus, in the ignition plug (1) which generates high-frequency plasma, corrosion of the fusion portion can be suppressed effectively, whereby durability is improved.

In this spark plug, the insulator has a leg portion inner circumferential surface which surrounds the rod portion; a cylindrical trunk portion inner circumferential surface which has a diameter larger than the diameter of the leg portion inner circumferential surface, surrounds the head portion, and has a center axis coinciding with the above axis; and a support surface which supports the head portion and extends continuously between the leg portion inner circumferential surface and the trunk portion inner circumferential surface. The seal portion has a seal portion outer circumferential surface in contact with the trunk portion inner circumferential surface; a seal portion abutment surface in contact with the support surface; and a connecting surface extending continuously between the seal portion outer circumferential surface and the seal portion abutment surface. In a cross section of the seal portion cut along a plane including the axis, a curve which is part of the contour of the seal portion appearing in the cross-section and is included in the connecting surface has a radius of curvature R of 0.1 mm or more.

摘要： In a spark plug including an electrode having a cover portion and a core portion, the occurrence of a gap between the cover portion and the core portion is suppressed. In a spark plug including a center electrode and a ground electrode that forms a gap between the center electrode and the ground electrode, at least one of the center electrode and the ground electrode has a cover portion and a core portion covered with the cover portion and formed of a material having a thermal expansion coefficient different from that of the cover portion. The core portion of the at least one electrode has a concave portion and a convex portion formed at the front end thereof. The convex portion is such that, in a cross section passing through the barycenter of the front surface of the electrode and also passing through the convex portion, the area of the convex portion delimited by a line perpendicular to the bisector of the convex portion and passing through a point 0.2 mm shifted from the front end of the convex portion in the direction of the bisector is smaller than the area of a triangle formed by connecting the front end of the convex portion and intersections of the line perpendicular to the bisector and the contour of the convex portion.
