Abstract

An ignition system for an internal combustion engine has a plurality of peripheral ignition gaps arranged at appropriate separations along the periphery of a combustion chamber and a center ignition gap disposed at a center of the combustion chamber. The ignition gaps are selectively used according to engine operating conditions so that only the peripheral ignition gaps produce sparks when the engine operates under low engine loads and the center ignition gap and the peripheral ignition gaps all produce sparks at once when the engine operates under high engine loads.
