Abstract

An inexpensive or economical ignition device which is capable of advancing the ignition timing in proportion to an increase in the engine speed when it stays within a preset range and obtaining constant minimum and maximum ignition angle characteristics when the engine speed is below and above the preset range, respectively, so that the ignition device may be operate in conformity with the output characteristic of an engine. A driving power source for the controller of the ignition device can be provided independently of the pulser coil, thereby to greatly stabilize the ignition characteristic in the low engine speed region.
