<P>PROBLEM TO BE SOLVED: To smoothly raise rotation speed of an engine to idling rotation region by positively urging a rise of the rotation speed of the engine after start-up. <P>SOLUTION: A capacitor charging/discharging type engine ignition device is provided with a magnet type generator 4 which is driven synchronously with an engine 1, a capacitor 10 for charging/discharging which is charged by positive half-wave output from a source coil 9 of a magnet type generator 4, a switching element 13 for discharging which makes a charging of the capacitor 10 for charging/discharging be discharged through an ignition coil 12 during conduction, and an ignition timing controller 18 which conducts the switching element 13 for discharging at the ignition timing corresponding to the rotation of the engine 1 by negative half-wave output of the source coil 9. The ignition timing controller 18 sequentially advances ignition timing every time the engine 1 rotates by a specified number at low speed rotation after start-up. <P>COPYRIGHT: (C)2012,JPO&INPIT |
