PURPOSE:To minimize piece number of parts in such a way that at least a piece of ignition coil is connected electrically to plural pieces of ignition plugs on its secondary side, and the primary side of the ignition coil makes simultaneous ignition through conduction and interruption by a piece of switching means. CONSTITUTION:A point 7 is opened and closed by a cam involved in the rotation of the engine. Opening and closing operations of this point 7 makes electric current streaming along to primary sides 31, 41 of the ignition coils 3, 4 conduct and interrupt, which induces high voltage on the secondary sides 32, 42. The high voltage on the secondary sides is supplied at the same time to the ignition plugs 8, 9, and 10, to produce simultaneous ignitions. |
