<p>PROBLEM TO BE SOLVED: To provide an engine unit and the like including a four-stroke engine body having a high load region and a low load region among four strokes, and simultaneously achieving both of shortening of the time to restart after an instruction of combustion stop, and loadability to a vehicle.SOLUTION: An engine unit includes a four-stroke engine body, a three-phase brushless motor, an inverter, and a control device. The control device controls a plurality of switching portions of the invertor in a state that combustion motion of the four-stroke engine body and normal rotation of a crank shaft are stopped, and an instruction for starting is not input, after the combustion motion of the four-stroke engine body and the normal rotation of the crank shaft are stopped, thus voltage applied to the three-phase brushless motor from a battery is controlled, and the crank shaft is normally rotated from a stop position to an expansion stroke in the four-stroke.</p> |
