記載の手持ち作業機用小型エンジン。[Claims for Utility Model Registration] (1) A magneto that has a rotor connected to the crankshaft of an engine and a stator with an ignition coil placed opposite to the rotor, and generates an alternating current voltage when the engine rotates; an ignition device that generates a spark discharge in an engine spark plug with a voltage of either positive or negative polarity of the output of the magneto; a starter motor for starting the engine; a secondary battery for driving the starter motor; a charging device for charging the battery with a voltage of the other polarity of the output of the magneto, wherein the rotor of the magneto fixes an alternating current voltage for spark discharge at the spark plug; a first magnet to be generated in the secondary ignition coil; and at least one magnet whose mounting rotational angle position on the rotor is shifted relative to the first magnet to generate alternating current voltage in the ignition coil at a time other than the compression stroke of the engine. two second magnets, wherein the first magnet and the second magnet are magnetized differently so as to give magnetic flux changes in opposite directions to the stator when the rotor rotates in one direction. A small engine for a hand-held power machine, characterized by being attached to the rotor in the orientation of . (2) A small engine for a hand-held working machine according to claim 1, wherein the first and second magnets are arranged at equal angular intervals on the rotor.
