<P>PROBLEM TO BE SOLVED: To provide a fuel injection control apparatus capable of controlling OT increase appropriately. <P>SOLUTION: The fuel injection control apparatus includes: a temperature acquisition means 20 that estimates the present temperature T2 of a catalyst 10 and the convergence temperature T1 of the catalyst 10; an increase value calculation means 22 that calculates a base OT increase value D1 that is an increase value of the fuel injection amount that a fuel injection valve 8 provided in an internal combustion engine needs to inject, on the basis of the present temperature T2 and the convergence temperature T1 estimated by the temperature acquisition means 20; a correction means 24 that calculates an OT increase correction-reflected value D2 by correcting the base OT increase value D1 on the basis of the present temperature T1 and the convergence temperature T2 if the present temperature T1 is lower than the convergence temperature T2; and an increase value determination means 26 that selects one of the base OT increase value D1 and the OT increase correction-reflected value D2 as the OT increase value of the fuel injection amount that the fuel injection valve 8 needs to inject, on the basis of the base OT increase value and the OT increase correction-reflected value D2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
