Abstract

The present invention provides an engine starting method from an idling stop condition wherein a preliminary step pushes a pinion to abut with a ring gear when a vehicle operating condition is in an idling stop condition, a starting step rotates the pinion into mesh with the ring gear by a motor upon receiving an engine start signal and thereafter an engine is started, and a restoring step is carried out after engine startup where the pinion is restored to an original position thereof. Also provided, when the engine is stopped, a pinion is meshed with a ring gear. Upon engine start-up, a pinion actuator disengages the pinion from the ring gear and a cutout portion engages an engaging piece to maintain the pinion disengaged. When the engine stops, a releasing actuator disengages the cutout portion and the engaging piece and the pinion is reset.
