Engine starting device and engine starting method

摘要

The engine starting device for stopping, when an engine automatic stop condition is satisfied, fuel injection to the engine to automatically stop the engine, and for thereafter restarting the engine when an engine restart condition is satisfied, includes: a ring gear coupled to a crankshaft of the engine; a starter motor rotated by a current supply; a pinion gear for transmitting the rotation of the starter motor to the ring gear; a pinion gear moving part for moving the pinion gear toward the ring gear by a current supply, thereby meshing the pinion gear with the ring gear; and a fuel injection control part for restarting the fuel injection so that combustion is generated in a predetermined compression cylinder after the engine restart condition is satisfied and after the pinion gear moving part starts the movement of the pinion gear.

1. An engine starting device for stopping, when an engine automatic stop condition is satisfied, fuel injection to an engine to automatically stop the engine, and for thereafter restarting the engine when an engine restart condition is satisfied,
the engine starting device comprising: a ring gear coupled to a crankshaft of the engine; a starter motor rotated by a current supply; a pinion gear for transmitting the rotation of the starter motor to the ring gear; a pinion gear moving part for moving the pinion gear toward the ring gear by another current supply, thereby meshing the pinion gear with the ring gear; and a fuel injection controller restarting the fuel injection at the same time the pinion gear moving part starts the movement of the pinion gear toward the ring gear so that combustion is generated in a predetermined compression cylinder after the engine restart condition is satisfied and after the pinion gear moving part starts the movement of the pinion gear.
