Abstract

An engine unit (EU) to be included in a straddled vehicle (1) is provided. The engine unit (EU) includes a four-stroke engine (10), a rotating electrical machine (20) that is used in common as a starter motor and a generator, an electromagnetic pickup (50) that generates a detection signals in accordance with a rotation of the rotating electrical machine (20), and a controller (60). The controller (60) has a combustion controller (63) for controlling a combustion operation of the engine (10) and a rotating electrical machine controller (62) for controlling the rotating electrical machine (20). The controller (60) executes a position specifying processing (S50) of specifying a position of a crankshaft (15), an idle stop control (S17, S18), a restart control (S41, S42), and a swing back control (S19). In the restart control (S41 to S43; S50 to S52), the controller (60) executes a start asynchronous injection control (S44 to S47) of making a fuel injector (18) perform asynchronous injection (S47) after beginning drive of the crankshaft (15) in a forward rotation direction by the rotating electrical machine (20).
