Provided is an engine unit that achieves improvement in both engine startability and vehicle mountability without use of a swing-back function and a decompression function, and, when used in combination with the swing-back function and/or the decompression function, achieves further improvement in the engine startability and the vehicle mountability. An engine unit mounted to a vehicle includes a starter motor. A flywheel provided in the starter motor includes magnetic pole faces that are provided on inner circumferential surfaces of permanent magnet parts with respect to a radial direction of the starter motor. The magnetic pole faces are arranged side by side in a circumferential direction of the starter motor. The number of the magnetic pole faces is more than 2/3 of the number of slots. At least at a time of starting a four-stroke engine body, a control device changes a current supplied to a winding of each phase, to thereby enable the flywheel to rotate with overcoming of a high-load region. |
