PROBLEM TO BE SOLVED: To provide a fuel injection control device of an engine capable of suitably making both compatible in low rotation of a target engine speed in an idle operation state and avoidance of an engine stall, in an engine having a cylinder injection injector and a pipe injection injector. SOLUTION: This fuel injection control device of the engine is applied to the engine 1 having the cylinder injection injector DI for injecting fuel into a cylinder C and a port injection injector PI for injecting the fuel into an intake pipe 31. The device injects the fuel by these respective injectors DI and PI by respectively setting a fuel injection quantity (a cylinder injection quantity) of the cylinder injection injector DI and a fuel injection quantity (a pipe injection quantity) of the port injection injector PI, when the engine 1 is put in an idle operation state. The device sets a value of adding a quantity increase value to the cylinder injection quantity as the fuel injection quantity of the cylinder injection injector DI when determining the effect of causing the engine stall on condition that the engine 1 is in the idle operation state.
