Patent ID: 8498801

Claim:
An engine start control system, comprising: an idle stop control configured to stop an engine upon establishment of a predetermined condition and configured to restart, by a throttle operation at the time of starting the engine, using a starting switch; a fuel injection system configured to perform simultaneous fuel injection until completion of a stroke discrimination; an ignition device configured to ignite at a preset fixed timing every one revolution of a crankshaft; and a storage unit configured to store, during execution of the idle stop control, a result of the stroke discrimination after initiating the engine starting, wherein, after completion of the stroke discrimination, the engine start control system is configured to perform a fuel injection and ignition control once every two revolutions of the crankshaft based on an output value of a lead (Pb) sensor, and wherein, at the time of restarting the engine by the idle stop control, the result of the stroke discrimination stored in the storage unit is used to drive the fuel injection system and the ignition device, instead of conducting a new stroke discrimination.
