High Performance Direct Sale Iridium Spark Plugs Silzkr7b11 9723 Car Parts Ignition System

Spark plugs are important components of the ignition system in gasoline engines. They can introduce high-voltage electricity into the combustion chamber and cause it to jump over the electrode gap to generate sparks, thereby igniting the combustible mixture in the cylinder. It mainly consists of wiring nuts, insulators, wiring screws, central electrodes, side electrodes, and the shell, with the side electrodes welded to the shell.

The working principle of a spark plug is that the insulation skirt of a standard spark plug is slightly shrunk into the end face of the housing, and the side electrode is outside the end face of the housing, making it the most widely used type. The insulation skirt of the edge protruding spark plug is longer and protrudes beyond the end face of the housing. It has the advantages of large heat absorption and good anti fouling ability, and can be directly cooled by the intake air to lower the temperature, so it is not easy to cause hot ignition, so the thermal adaptation range is wide.
