<P>PROBLEM TO BE SOLVED: To provide a device and an assembly used for extending life of a spark igniter. <P>SOLUTION: An igniter 40 includes a shell comprising: a base; a tip surface 202; a sidewall 204 extending both the base and the tip surface and surrounding a cavity 206; a shell hole 208 extending from the tip surface 202 to the cavity 206; and a pin 210 embedded in the tip surface 202 and nearly extending in a tangential direction to the shell hole 208. The igniter also includes an electrode 212 arranged in the shell, and the electrode 212 includes an ignition far-end section located in the vicinity of the shell hole 208. The igniter further includes an insulator 216 arranged between the shell and the electrode 212 in the shell, and the insulator 216 includes an insulator hole 218 nearly aligned to the shell hole 208. <P>COPYRIGHT: (C)2011,JPO&INPIT |
