PURPOSE:To enable change-over two-point ignition and one-point ignition substantially and smoothly by providing the ignition timing of ignition plugs at two points with phase difference is response to the speed of revolution of an engine. CONSTITUTION:A pair of ignition timings 7A, 7B is each disposed in an engine combustion chamber 6. A distributor 8, distributors 9A, 9B and a rotor 10 are stacked on the same shaft. A transistor Tr3 is turned OFF, an engine is ignited by means of the ignition pulgs 7A, a transistor Tr6 is turned OFF being delayed only by the setting time of a timer circuit 14, and the engine is ignited by means of the ignition plug 7B. |
