PURPOSE:To save electric power and fuel consumption, by both directly connecting an ignition coil to a spark plug of each cylinder and distributing a signal from a spark advance control circuit separately to each cylinder thus performing generation of high voltage and distribution of ignition energy. CONSTITUTION:An ignition device is constituted by a spark advance spark energy control circuit 11, ignition circuit 12, consisting of a distribution circuit 42 classified by a cylinder, trigger circuit 43, oscillation temporary stop circuit 44, thyristor 45, capacitor 46, etc., voltage booster circuit 13, ignition coil 5, arranged at each cylinder, combination part 14 of a spark plug 9 and low voltage cord 15. In this way, the necessity for using a large power loss part such as center cord, high tension cord, mechanical distributor, etc. can be eliminated, and voltage of a battery 4 is boosted and charge voltage of the capacitor 46 is controlled to arrange ignition energy suitable for the operational condition of an engine, thus electric power consumption can be substantially reduced to improve fuel consumption. |
