A spark plug ignition tip for an electrode of a spark plug device, in particular a prechamber spark plug, having a base body that has a first axial end, a second axial end and a circumferential section situated between them; the base body contains a precious metal or precious metal alloy; the first axial end and/or the circumferential section is embodied for fastening the base body to an electrode; the second axial end has a dome-shaped section; and the base body is produced by powder metallurgy.

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.

The present invention relates to a series clearance multi-point discharging spark plug for a spark ignition engine, including a wiring screw. The wiring screw is arranged in an insulator. A central electrode is arranged in a tip of the insulator. A built-in damping resistor is arranged between the central electrode and the wiring screw. A ceramic multi-point discharging ignition table fitted with the insulator is arranged at a bottom of the insulator. A cavity assembly is formed between the ceramic multi-point discharging ignition table and the insulator. An outer wall at an upper end of the ceramic multi-point discharging ignition table is fastened to the shell. An ignition electrode assembly is arranged at the bottom of the ceramic multi-point discharging ignition table. The series clearance multi-point discharging spark plug increases temperature and pressure of mixed gas during ignition, thereby improving ignition performance, shortening combustion duration and improving engine performance.

An ignition plug wire for an internal combustion engine has an elongated conductor with a programmable capacitor module disposed in-line with the elongated conductor. The programmable capacitor module is configured to step up or convert the ignition voltage normally supplied by an ignition coil to a plasma voltage. An inventive ignition plug if configured such that the anode enclosed within the insulator includes or is replaced by a voltage converting module designed to convert the ignition voltage into a plasma voltage. The voltage converting module consists of a semiconductor circuit, a composite semiconductor material, or a capacitor.

A plasma header gasket for use with an internal combustion engine includes plasma-igniters disposed around the perimeter of apertures in the gasket corresponding to piston cylinders in the engine. The plasma-igniters produce a plasma ionization field in time with the engine to increase the efficiency of combustion.
