Title: Noise preventive device for ignition device of engine
Inventor: KASUYA HIDEO
IPC: F02P7/02
Filed: 1981-04-24
Abstract: PURPOSE:To suppress a harmful radio noise in a device, by feeding high voltage to each spark plug from a distributor through a high tension cable, changing a resistance value per unit length of the high tension cable in accordance with its length and almost equlizing a resistance value of each high tension cable. CONSTITUTION:A high frequency component, generated by a spark discharge in a gap of spark plugs 6A-6D at ignition, flows in each part of an ignition device through high tension cables 11A-11D, and is emitted to the surroundings as a radio noise. To suppress this noise, the high tension cables 11A-11D are generally provided with a resistance value to attenuate a noise current of high frequency component. While if the high tension cables contain even a cable in shorter length, that is, a lower resistance, a noise preventing effect is rapidly decreased. In consequence, a resistance value per unit length is changed, and resistance values of the high tension cables are almost equalized to suppress a noise.
