    摘要: An engine-generator starting apparatus a three-phase winding equipped with a generating unit that rotates relative to rotation of a crankshaft of an engine, and an electronic control unit that controls supply of electric current the three-phase winding to rotate the crankshaft and start the engine. In the apparatus, the electronic control unit controls to supply first current to the three-phase winding to make the engine crankshaft of rotate reverse, the first current is of a level for stopping the piston connected to the crankshaft at a position in a compression stroke. Then it controls to supply second current (that is greater than the first current) to the three-phase winding to make the crankshaft of the engine rotate forward when a predetermined time period has elapsed, and control to ignite fuel supplied to the engine after the second current is supplied to the three-phase winding.
