PROBLEM TO BE SOLVED: To provide a fuel injection control device for an internal combustion engine, capable of deciding a value of the fuel injection quantity which is appropriate to the then present charge efficiency and of appropriately and easily controlling the fuel injection through easy computation of the fuel injection quantity, the device being provided with two kinds of variable valve mechanisms capable of changing the cam phase and cam profile. SOLUTION: A control device 1 for the internal combustion engine 3 is provided with an ECU 2. The ECU map-retrieves a multiplication term Ati for a high-speed cam and a low-speed cam, in response to the engien speed NE and a cam phase CAIN (steps 100, 101, 104), and map-retrieves an addition term Bti for the high-speed cam and the low-speed cam in response to the engine speed NE and the cam phase CAIN (steps 100, 102, 105), and computes the basic fuel injection time Tibase as a sum of the product of the intake in-pipe absolute pressure PBA and the multiplication term Ati with the addition term Bti (Ati.PBA+Bti) (step 103). |
