Abstract

PURPOSE:To lower the noises produced by electric waves in a particular frequency range, by providing in an ignition system an LC parallel circuit consisting of an inductance component and a capacitance component connected in parallel to each other. CONSTITUTION:An ignition device of this invention comprises an LC parallel circuit having an inductance component and a capacitance component connected in parallel to each other in an ignition system including an ignition coil 1, a resistance- incroporated plug 2, and a plug cord 3 for connecting them (1, 2) to each other. The LC parallel circuit is preferably disposed at a position near the ignition plug 2 where a high noise current is produced, and it is assembled, for instance, in a plug cap 4. Here, it is preferable that the inductance and capacitance of the LC parallel circuit and its particular frequency range are selected to be 0.1-2muH, 1-30pF, and 30-500kHz, respectively. With such an arrangement, it is enabled to effectively lower the noises produced by electric waves in the particular frequency range.
