A fuel injection apparatus for an engine includes various sensors (10), a control unit (20) and an injector (30). The control unit (20) includes a basic fuel injection quantity arithmetic means for determining a basic injection quantity conforming to the operation state, a data map (21) holding data for determining a regulating correction quantity in accordance with specific engine parameters (Th, Ne), and a correcting arithmetic means for determining the injection quantity by correcting the basic injection quantity with the data. The data map (21) includes plural areas for holding the data. Intermediate areas holding no data are provided between two adjacent data holding areas. The correcting arithmetic means includes a search means for determining interpolation data corresponding to the intermediate area through interpolation based on the data stored in two adjacent areas. The injection quantity for the intermediate area is determined by correcting the basic injection quantity with the interpolation data.
