Purpose, Function
The spark plug generates spark, ignition of the air-fuel mixture occurs, and combustion of the air-fuel mixture is triggered.
Construction
The spark plug is installed to the cylinder head.

Iridium on the center electrode and platinum on the ground electrode are used (iridium spark plug).
Because iridium has excellent durability, extreme thinning on the center electrode is achieved.
The area contacting flame is decreased by extremely thinning the center and setting electrodes, and extinction action is reduced. Therefore, excellent ignition performance is achieved.
