<p><P>PROBLEM TO BE SOLVED: To provide a method for generating negative ions for automobile for emitting negative ions of high density by applying negative high-voltage DC pulses with the voltage of≥-3,000 V, and the pulse number of≥6,000 and changed in proportion to the engine speed to fuel-air mixture to be fed in an engine, combustion exhaust gas or a negative ion emission electrode disposed in an insulated manner in a cabin space. <P>SOLUTION: A piezoelectric ceramic module is brought into tapping contact with a tapping piezoelectric member which is integrally rotated with a crank shaft and has tapping projections formed on an outer circumferential surface thereof at a predetermined interval at the tapping projections of the tapping piezoelectric member to generate the high pulse-shaped power, which is converted into ON-OFF current signals of high pulse by a power transistor of a conversion circuit, and input in a primary coil of an ignition coil. The negative high-voltage DC pulses with the voltage of≥-3,000 V, and the pulse number of≥6,000 and changed in proportion to the number of rotation of the crank shaft are output and applied to a negative ion emission electrode to emit negative ions of high density. <P>COPYRIGHT: (C)2004,JPO</p> |
