Abstract

PURPOSE:To increase combustion efficiency at the time of low load of an engine and decrease the combustion noise at the time of high load by increasing the injection rate from a second injector at the time of low load of the engine and the injection rate from a first injector at the time of high load of the engine. CONSTITUTION:In a rotary piston engine 1, a first injector 11 for injecting fuel in the normal direction and a second injector 12 injecting the fuel in the opposite direction in relation to an intake air flow B in response to the rotation of a rotor 4 are provided. As fuel injection characteristics from the first and second injectors 11, 12 against the load change of the engine, an entire injection amount from both injectors 11, 12 are increased linearly in response to the raise up of the load. Therefore, in a low load zone until the load reaches a prescribed value L0, the entire injection amount is controlled by a control unit 18 so that the combustion characteristic can be expedited so as to improve its heat efficiency and fuel consumption performance by the injection in the opposite direction from the second injector 12 and in a high load zone beyond the prescribed value L0, the injection rate in the normal direction from the first injector 11 is increased gradually so that the rapid combustion can be retrained and the combustion noise can be reduced.
