PROBLEM TO BE SOLVED: To provide the fuel injection timing control device of a diesel engine reflected the difference of the effect to the fuel injection timing of a prestroke amount following to the difference of an engine temperature. SOLUTION: A fuel injection timing (eacld2bse+emacldq×eqfin) is corrected and the injection timing (eacld2) at a cooling time is set (S180, S190), based on a base prestroke amount (eaplstb) and the prestroke correction coefficient (t-mplstthw) S170) at the cooling time found out responding to the cooling water temperature (gthw). Thus, by correcting the fuel injection timing responding to the engine temperature and prestroke amount of a diesel engine, the difference of the effect to the prestroke amount between the cooling time and after warming up can be reflected to the fuel injection timing. Therefore, a proper fuel injection timing can be set for favorable combustion.
