PURPOSE:To prevent the combustion fluctuation accompanied by the operation of a pumping loss mechanism by gradually increasing respectively the rate of the fuel injection amt. in a cylinder and the opening of the control valve opening and closing a slow closing suction port at the transfer time from the fuel injection in a suction passage to the fuel injection in a cylinder. CONSTITUTION:A rotary piston engine is provided with a rotor R so that it performs a planetary rotation around an eccentric shaft 5 at the internal part of a casing 10. A main suction port 13 and the slow closing suction port 14 closed by delaying more than it are opened in a combustion chamber. In this case, a control valve 17 opening and closing the slow closing suction port 14 is provided thereon. In a suction passage 18 and work chamber 16 each 1st and 2nd fuel injection valves 23, 30 are provided. Said each valve 17, 23, 30 is respectively controlled by a CPU 32. At this time the rate of a fuel injection amt. by a 2nd fuel injection means 30 and the opening of the control valve 17 are gradually increased respectively at the transfer time from the 1st fuel injection means 23 to 2nd fuel injection means 30. |
