摘要： In a fuel supplying mechanism in which fuel delivery pipes of a non-return type are disposed, the generation region of pulsation resonance is arbitrarily controlled, thereby eliminating various disadvantages otherwise occurring where the pulsation resonance point exists in a favorable rotation region for normal use of the engine. A pair of the fuel delivery pipes 1, 2 of a non-return type is disposed for each bank of a horizontal opposed type or V-type engine and coupled with a connection pipe 4. A characteristic period time of a pulsation wave induced by the pulsation wave generated during fuel injection of the injection nozzles 3 via a connection pipe 4 coupling between one to the other of the fuel delivery pipes 1, 2 is controlled to render the characteristic period time longer to shift the pulsation resonance point out of a low rotation region of the engine as well as to render the characteristic period time shorter to shift the pulsation resonance point out of a high rotation region of the engine.
