PROBLEM TO BE SOLVED: To provide a fuel injection control for an engine capable of making an air fuel ratio appropriate by adjusting the fuel injection control quantity based on a detection result of a suction air quantity detection means such as an air flow sensor. SOLUTION: This device is provided with a suction air quantity detection means detecting suction air quantity of an engine, a cylinder filling efficiency detection means detecting cylinder filling efficiency based on a detection result of the suction air quantity detection means, a rotation speed detection means detecting engine rotation speed, a suction air pressure detection means detecting suction air pressure in an intake system of the engine, a limit value operation means operating a limit value of a detection value of cylinder filling efficiency based on a detection value of the rotation speed detection means and a detection value of the suction air pressure detection means, and a fuel injection control quantity operation means operating fuel injection control quantity of the engine based on cylinder filling efficiency and operating fuel injection control quantity based on the limit value if the detection value of the cylinder filling efficiency exceeds the limit value.
