PROBLEM TO BE SOLVED: To maximally promote vaporization and atomization of fuel by an intake flow, even if an intake flow place is changed by its operation state, in a rotary piston engine 1 for directly injecting the fuel into an operation chamber 5. SOLUTION: This fuel injection system has first and second injectors 30 and 31 respectively injecting the fuel toward intake ports 11 and 13 by facing a trochoidal inner peripheral surface 2a of a rotor housing 2, having one injecting the fuel near the always opening first intake port 11 and having the other injecting the fuel near the opposite side. The fuel is injected by the first injector 30 in a low rotation first operation area (I), particularly, in a low load-low rotation area R1, and the fuel is injected by the second injector 31 in an area R2 on the higher load or higher rotation side than that area.
