In an engine fuel supply method, a first fuel pressure difference between a fuel injection amount computation timing and a first fuel injection timing and a second fuel pressure difference between the fuel injection amount computation timing and a second fuel injection timing are estimated at the fuel injection amount computation timing based on a control state of a fuel pneumatic transportation amount of a high-pressure fuel pump. The first fuel injection amount is corrected based on the first fuel pressure difference and the second fuel injection amount is corrected based on the second fuel pressure difference. A fuel injection valve is selectively controlled to supply the high-pressure fuel directly into a cylinder of the engine at the first fuel injection timing with the corrected first fuel injection amount and at the second fuel injection timing with the corrected second fuel injection amount.
