PCT No. PCT/JP93/01627 Sec. 371 Date Jun. 29, 1994 Sec. 102(e) Date Jun. 29, 1994 PCT Filed Nov. 9, 1993.A basic discharge QK Of a fuel pump is determined based on an engine load and an engine rotational speed, and further a correction amount QG for correcting the basic discharge QK based on comparison of an actual fuel pressure PT with a target pressure Po is learnt for every driving conditions. Then, the basic discharge QK is corrected with the correction amount QG, whereas in a transient condition, the basic discharge QK is corrected with a transient correction amount QT set on the basis of a variation rate DELTA PT Of the fuel pressure PT. Thus, it is possible to ensure that an amount of fuel required by an engine is surely supplied without excess fuel supply from the fuel pump.
