PURPOSE:To enable to correct the fuel increasing or decreasing rate corresponding to an engine warming up in an internal-combustion engine of the type in which a reference fuel injection rate is corrected according to he operational conditions of the engine, by correcting the fuel increasing rate for acceleration and the fuel decreasing rate for deceleration by use of a correction factor corrected by a multiplication factor according to the engine temperature at the time of warming up of the engine. CONSTITUTION:In controlling an injection valve 30 by determining a datum fuel injection rate from a signal relating to the pressure in an intake pipe, given from a sensor 23 for detecting the pressure in the intake pipe, and an engine-speed signal given from a crank angle sensor 44 in a control circuit 54, the fuel increasing rate is corrected by use of a correction factor of a prescribed positive value when an ''idle'' switch of a throttle sensor 20 is turned OFF. The fuel increasing or decreasing rate is corrected by use of a correction factor that is increased or decreased appropriately when it is detected from the output of a potentiometer of said sensor 20 that the opening of a throttle valve has become smaller or greater than a prescribed value. Further, at the time of warming up of an engine, control is made to correct the correction factor at the time of increasing or decreasing fuel injection rate according to the output of a sensor 46 for detecting the temperature of cooling water. |
