Zusammenfassung:	A first sensor (5, 16) detects whether an engine revolution speed change ( DELTA Ne) exceeds a predetermined amount, and a second sensor (5, 17) detects whether an accelerator opening (Ac) stays within a predetermined range. A controller (5) determines a target amount of fuel injection (Qfnl) that is greater than a basic amount of fuel injection (Qbase) when the engine revolution speed change exceeds the predetermined amount and the accelerator opening stays in the predetermined range. The basic amount of fuel injection is determined based on the accelerator opening and engine revolution speed (Ne). By feeding a slightly larger amount of fuel than the basic value while an engine brake is applying, the engine revolution speed change is suppressed and shock upon clutch engagement is reduced.
