Abstract
A fuel injection control device controls a spark-ignition engine of an intra-cylindrical direct fuel injection type. The engine includes a fuel injection valve configured to directly inject a fuel to an interior of a cylinder, and a spark plug configured to ignite, by a spark, an air-fuel mixture inside the cylinder. When the injected fuel collides with a portion in a predetermined low-temperature state, the fuel is injected while changing a fuel injection condition under predetermined operating conditions so as to restrain a fuel spray from keeping colliding with the same position continuously.
