摘要
A spark plug comprising: an insulator shell; a center electrode inside the insulator shell such that one end of the center electrode protrudes from the insulator shell; a metal shell exterior to the insulator shell; a side ground electrode having one end coupled to the metal shell and the other end facing the protruding end of the center electrode to form a spark discharge gap between the center electrode and the side ground electrode; and a metal tip on at least one of the side ground electrode or the center electrode, located at the spark discharge gap, that is a platinum-based alloy including 23-35 weight percent palladium, greater than 0 to 10 weight percent iridium and the balance being platinum.
