Ignition device for a multi-cylinder internal combustion engine

An ignition device for a multi-cylinder internal combustion engine having an ignition coil, the two primary windings of said ignition coil being wound in opposite directions from each other, positive and negative high voltages being alternately generated across the secondary winding of said ignition coil, and a distributor, said distributor comprising a center electrode;

• two electrical distributing conductors in the rotor of said distributor, said center electrode being connected electrically with said two electrical distributing conductors, said electrical distributing conductors including at least one center conductor and two projecting conductors for distributing electric power to side electrode;
• two diodes having opposite polarities from each other and connecting said center conductor and said projecting conductors for electrical distribution, respectively, and;
• a plurality of side electrodes adapted to be electrically coupled successively with said projecting conductors according to the rotation of said rotor;
• whereby said positive and negative high voltages are supplied alternately to said side electrodes through said corresponding projecting conductors.
