PURPOSE:To prevent the stagnation of additionally injected fuel and enable the optimum setting of injection completion timing in an ordinary condition by advancing preliminarily the injection completion timing in acceleration at a low temperature where additional fuel injection time after the completion of the predetermined fuel injection timing becomes long. CONSTITUTION:When an internal combustion engine is in an acceleration condition while the temperature thereof detected via an engine operation condition detecting means A is equal to or lower than the predetermined value, injection completion timing for a low temperature start earlier than the predetermined normal injection completion timing is set by an injection completion timing setting means B. Also, the injection time for fuel is operated by an injection time operation means C on the basis of the operation condition of the internal combustion engine detected by said means A. Furthermore, injection start time is set by an injection start timing setting means D on the basis of the predetermined injection time so as to execute the predetermined injection completion timing. And at the predetermined injection start, an injection control means E actuates a fuel injection valve F and fuel is thereby injected during the predetermined injection time. On the other hand, upon completion of the predetermined fuel injection, an additional injection control means G additionally actuates the fuel injection valve F during additional time corresponding to the operation condition of the internal combustion engine.
