PROBLEM TO BE SOLVED: To provide a fuel injection control method for an internal combustion engine with improved maneuverability, enabling shifting to low load operation during operation of the engine while keeping combustion performance and exhaust gas performance favorable over the whole operation range of the engine in the internal combustion engine with a plurality of fuel injection valves mounted on one cylinder, and its device. SOLUTION: In the internal combustion engine, one cylinder is provided with the plurality of the fuel injection valves having a valve opening pressure regulator regulating valve opening pressure of a needle valve. The valve opening pressure regulator is operated and the needle valve of at least one of the fuel injection valve out of the plurality of the fuel injection valves is pressed with pressure not less than the valve opening pressure to block the fuel injection of the fuel injection valve.
