The present invention provides an engine unit, or the like, having a high-load region and a low-load region, and capable of lessening a variation in the position where rotation of a crankshaft stops after combustion of a four-stroke engine body is stopped. The engine unit includes: a four-stroke engine body having a high-load region and a low-load region; a three-phase brushless motor that starts the four-stroke engine body and generates power after starting the four-stroke engine body; an inverter including a plurality of switching parts; and a control device. The control device is configured to, while the crankshaft is in forward rotation after a combustion operation of the four-stroke engine body is stopped, control the plurality of switching parts so as to short-circuit terminals of a plurality of windings such that a resistance is applied to the forward rotation of the crankshaft, forcing the crankshaft to stop forwardly rotating in a compression stroke of the four-stroke engine body. |
