摘要： A fuel delivery rail assembly for supplying fuel to a plurality of fuel injectors in an engine is provided. The assembly comprises an elongate conduit having a longitudinal fuel passage therein, a fuel inlet pipe, and a plurality of sockets. Outer walls of the conduit include at least one flat or arcuate flexible first absorbing surface, which is smoothly and integrally connected to an arcuate second absorbing surface. The first absorbing surface or the second absorbing surface faces fuel inlet ports of the sockets. The sectional configuration of the conduit can be flat, a telephone receiver shape, a character “T” shape, a corrugation shape, a dumbbell shape or a reverse eye mask shape. Thus, fuel pressure pulsations and shock waves are reduced by abrupt enlargements of fuel passages and bendings of the absorbing surfaces.

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.
