摘要： A pulsation reducing system for a fuel line of an internal combustion engine, especially for an automotive engine equipped with an electronic fuel injection system is provided. The system includes a fuel delivery rail, a fuel tank, and a longitudinal main fuel pipe. A first flexible tube is arranged between the fuel delivery rail and the main fuel pipe. A second flexible tube is arranged between the main fuel pipe and the fuel tank. A small-ID tubular portion is arranged within the first tube or near the connecting portion of the first tube. The inside diameter of the small-ID tubular portion is smaller than that of the main fuel pipe. The length of the small-ID tubular portion is set between 10 to 50 times the inside diameter of the small-ID tubular portion itself. Thus, standing waves and resultant pressure pulsations caused by the fuel delivery rail are reduced by the small-ID tubular portion.

摘要： A returnless type fuel delivery pipe is provided for each cylinder bank of an opposed type engine. A connecting pipe is connected to this pair of fuel delivery pipes, a supply pipe is connected to this connecting pipe, thus coupling the fuel delivery pipes with the fuel tank. The fuel delivery pipes are made to be capable of absorbing and reducing pressure pulsation through elastic deformation of the external walls thereof, and the supply pipe is connected to an intermediate section of the length of the connecting pipe. Pressure pulsations with opposite phases caused by fuel injection of the fuel delivery pipes interfere with and attenuate each other in the supply pipe at or near intersection thereof with the intermediate section of the connecting pipe.

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.
