To provide a desired injection quantity regardless of an injection timing in a direct injection type engine.

Engine operational conditions (engine number of revolution Ne, accelerator opening degree Acc) are read in (S1), so as to set the fundamental injection time Tp(S2) and an injection timing θinj is set (S3). By referring to a table for storing cylinder inside pressure in relation to a crank angle per cylinder per area, cylinder inside pressure Pcy1-inj at the injection timing θinj is read in (S4). Then a differential pressure ΔP between fuel pressure Pfuel and the cylinder inside pressure Pcy-inj is found out (S5) and according to this different pressure ΔP, the fundamental injection time Tp is corrected to obtain the final injection time Ti (S6).
