Mazda CX-5 Service & Repair Manual: Spark Plug [Skyactiv G 2.0]
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.
