Claim 2:
3. The fuel injection control device according to claim 1, wherein the controller is configured to calculate a swirl flow intensity in the cylinder during a scavenging stroke, and
wherein, in the moment of swirl calculating step, the controller is caused to read out, in the swirl flow intensity calculating step, the swirl flow intensity in the cylinder at end of the scavenging stroke, calculate a swirl flow intensity at end of piston compression on the basis of the swirl flow intensity at end of the scavenging stroke, and calculate the momentum of swirl on the basis of the calculated swirl flow intensity at end of piston compression and an air amount in the cylinder.
