Fuel injection control device

A fuel injection control device comprising:

• an electronic control unit configured to
• (a) update and store a learning value compensating for a steady deviation between an actual air-fuel ratio and a target air-fuel ratio through an air-fuel ratio feedback control during operation of an engine,
• (b) correct a fuel injection amount by using the learning value,
• (c) detect whether or not fuel is replenished,
• (d) start fuel injection using fuel after being replenished and a fuel injection amount corrected based on a stored learning value when the stored learning value at a timing when the electronic control unit determines that fuel is replenished is included in a predetermined range from a first predetermined value to a second predetermined value, the first predetermined value being a value used when an amount increase correction of fuel is performed, the second predetermined value being a value used when an amount decrease correction of fuel is performed, and
• (e) start fuel injection using fuel after being replenished and a fuel injection amount in a predetermined injection amount range when the stored learning value at a timing when the electronic control unit determines that fuel is replenished is not included in the predetermined range, the predetermined injection amount range being a range of a fuel injection amount corrected by the learning value in the predetermined range.
