INTERNAL COMBUSTION ENGINE

To control fuel injection timings to two intake ports of a cylinder to promote mixing and gasification of the fuel, the internal combustion engine includes a first intake port (7a) and a second intake port (7b) which are connected to a cylinder (9), a first intake valve (15a) of the first intake port (7a), a second intake valve (15b) of the second intake port (7b), a first fuel injection valve (19a) for injecting fuel to the first intake port (7a), a second fuel injection valve (19b) for injecting fuel to the second intake port (7b), and a fuel injection control unit (65). The first intake valve (15a) is configured so that an opening timing of the first intake valve (15a) is advanced relative to an opening timing of the second intake valve (15b). The fuel injection control unit (65) is configured to perform fuel injection by the first fuel injection valve (19a) in advance of injection timing of the second fuel injection valve (19b).
