1. A fuel injection control device for controlling fuel injection performed by a fuel injection device disposed in a cylinder of a two-stroke engine, comprising:
a controller and a storage storing information that causes the controller to,
acquire a parameter related to a state quantity of scavenging and exhaust gas in the cylinder;
calculate a momentum of swirl generated in the cylinder on the basis of the acquired parameter; and
calculate an injection pressure of fuel from the fuel injection device corresponding to the calculated momentum of swirl,
wherein the fuel injection device is controlled to inject fuel into the cylinder at the calculated injection pressure.
