Abstract: In an engine starting apparatus, together with a one-way clutch, a pinion is pushed toward a ring gear of an engine mounted in a vehicle. The one-way clutch has an idling torque smaller than a torque of the ring gear that tries to turn the pinion when the pinion is pushed to the ring gear. By a control device, a pinion pushing device is enabled to operate when i) the revolution speed of the ring gear is larger than a revolution speed of the pinion and ii) a relative revolution speed between the revolution speed of the ring gear and the revolution speed of the pinion is a desired value.

Abstract: An electromagnetic solenoid having an electromagnetic coil, a fixed iron core, a movable iron core, and a spring coil. The spring coil, arranged between the fixed and the movable iron core, supplies a spring force to the movable iron core toward an opposite direction of the fixed iron core along the axial direction. A magnetic attraction surface and a fitting part are formed in at least one of the fixed iron core and the movable iron core. The magnetic attraction surface is contacted with the fixed iron core when the movable iron core reaches the fixed iron core. An outer peripheral surface of the fitting part, apart from the magnetic attraction surface by a predetermined distance along the axial direction, is engaged with the spring coil. The most outer peripheral part of the magnetic attraction surface is positioned inside rather than the most outer peripheral part of the fitting part.

Abstract: In a system, a starter includes a motor for rotatably driving an output shaft with a pinion and an actuator that shifts the pinion toward a ring gear to be engaged with the ring gear. A monitor unit monitors a rotational speed of the internal combustion engine. The rotational speed of the internal combustion engine drops after an automatic control for stop of the engine. When an engine restart request occurs with the rotational speed being within a preset range during the rotational speed of the internal combustion engine dropping by the automatic control for stop of the engine, a drive unit drives the actuator to shift the pinion toward the ring gear to be engaged with the ring gear. The drive unit rotatably drives the motor with the pinion being engaged with the ring gear to thereby crank the crankshaft.

Abstract: A starter to start an engine mounted on a vehicle provides an electromagnetic solenoid to push a pinion gear towards a ring gear side, an electromagnetic switch to open and close a motor contact point. The electromagnetic solenoid and the electromagnetic switch are individually controlled by an Electronic Control Unit i.e., ECU. When an idle-stop is triggered, the ECU controls a starter relay to be closed during the ring gear is rotating whereby the pinion gear together with a clutch are pushed out to counter-motor direction by the electromagnetic solenoid. As a result, the pinion gear meshes with the ring gear that is rotating at lower rotational speed. Therefore, the inertial mass of the starter is added to the ring gear so that swinging of the engine can be suppressed.
