Abstract

PURPOSE: To provide an ignition device, capable of reducing generation of noise wave effectively, by connecting a terminal of an ignition switch to a non-grounded electrode of a capacitor directly by a single lead wire, and connecting said non-grounded terminal of the capacitor to an external resistance by another lead wire.
CONSTITUTION: A terminal X of an ignition switch 2 is connected to a non- grounded electrode Y of a capacitor 9 directly by a single lead wire W1, and another lead wire W2 extended from the electrode Y is connected to a terminal Z of an external resistance 4. With such an arrangement, high-frequency current produced by the opening and closing of a contact point 7 and that induced by the spark ignition produced at a distributor gap 5 and a gap 6 of an ignition plug is passed necessarily to the electrode Y via the lead wire W2. Here, since the impedance of the capacitor 9 is extremely small for the electrode Y, high- frequency current causing noises is passed almost to the capacitor 9 but not passed through the lead wire W1, so that it is enabled to reduce generation of noise wave.
