PURPOSE:To correct the variation of the viscosity of fuel by inputting a fixed driving signal into a fuel injection timing adjusting actuator in idling and obtaining the viscosity of fuel according to the deviation from the actual value at this time and correcting the injection amount in accordance with the viscosity. CONSTITUTION:In Step 1, it is judged whether an engine is in idling or not. In idling, fuel injection timing feedback control is suspended, and a fixed driving signal is input into an actuator. The actual injection timing at this time is obtained, and the viscosity of fuel is obtained from said injection timing. In Step 5, the set value for fuel injection amount is corrected according to said viscosity. Thus, the variation of fuel viscosity can be corrected. |
