Spark plug configuration having a noble metal tip

Improved Configuration specific ignition end to meet a range of different sizes for the performance as a spark plug having the spark plug generally comprises a shell, an insulator, and each of the improved copper core with improved corrosion for the heat-conductive protection and corrosion-resistant It includes a center electrode and a ground electrode having an electrode having a noble metal insert for. The noble metal insert for the central electrode is preferably in the form of a cylinder of the iridium-based tip, which is received into a complementary recess formed in the center electrode. For the ground electrode noble metal insert is in the form of a platinum-based flat pad attached to the surface of the ground electrode. The range of different sizes to each other individually and in combination with different sizes to provide the various components of the spark plug assemblies.An internal combustion engine, a spark plug, the axial hole, a shell, an insulator, a thermally conductive core, a metal cladding, a main shank portion, the recess, the collar portion, the central electrode, the noble metal tip and the ground electrode.
