PROBLEM TO BE SOLVED: To provide a fuel injection control device of an engine of an inexpensive configuration in which two injectors for each cylinder are individually controlled with excellent accuracy. SOLUTION: Main injectors M1-M4 and sub injectors S1-S4 are provided at each cylinder of the engine. An ECU 10 has a first CPU 11 and a second CPU 12. The first CPU 11 calculates a fuel injection control value based on an engine operating condition each time, and outputs injection pulses of the main injectors M1-M4 from the result of calculation. The second CPU 12 inputs injection pulses outputted from the first CPU 11, and outputs injection pulses of the sub injectors S1-S4 based on each edge timing of the input pulse. COPYRIGHT: (C)2003,JPO
