PROBLEM TO BE SOLVED: To provide a fuel injection control device of an internal combustion engine, which reduces emission while ensuring starting capability at the time of cold start of the internal combustion engine. SOLUTION: An internal combustion engine 1 is provided with an intracylindrical injector 41 and an intake port injector 42. An ECU 60 is provided with: a fuel injection time calculating part 65 for calculating the demanded fuel injection time; and a fuel injection control part 71 for having the intracylindrical injector 41 inject the fuel in a compression process at the time of cold start and having the fuel injected in addition to the fuel injection by the intracylindrical injector 41 in the compression process. Thereby, the starting capability at the cold start is ensured even in the case where the demanded fuel injection time is longer than the interval time, and HC and CO in the exhaust gas are reduced. As a result, emission is reduced while ensuring the starting capability at the time of cold start of the internal combustion engine 1. COPYRIGHT: (C)2008,JPO&INPIT
