Abstract
An engine driving apparatus includes an engine, a starter motor, and a starter motor controller. The engine includes a plurality of cylinders. When any one of the plurality of cylinders enters a compression stroke, another one of the cylinders enters an expansion stroke. The starter motor is coupled to a crankshaft of the engine. The starter motor controller is configured to control the starter motor. Before restarting the engine, the starter motor controller performs pre-restart control for adding torque to the crankshaft by using the starter motor to open an exhaust valve of the cylinder in the expansion stroke.
