Abstract
An ignition system that sufficiently utilizes the energy output from a power supply, to thereby realize excellent ignition performance. The ignition system includes an ignition plug having a spark discharge gap formed between a center electrode and a ground electrode, and a power supply for supplying electric energy to the spark discharge gap. Electric energy output from the power supply for producing spark discharge of one unit is set to 100 mJ or greater. S1≧[{−30 (mm)×G1+60}/100]×S2 and G1<2.0 are satisfied wherein G1 represents the size (mm) of the spark discharge, S1 represents an area (mm) defined with a region obtained by removing, from a projection region of the center electrode, a region where the projection region overlaps with a projection region of the ground electrode and S2 represents an area (mm) defined with the projection region of the center electrode.
