<P>PROBLEM TO BE SOLVED: To provide a delivery pipe pressurizing fuel supplied to a plurality of fuel injection valves right after starting an engine. <P>SOLUTION: The delivery pipe 6-1 comprises a connection parts 61c-f for mutually connecting the plurality of fuel injection valves 2a-d which supply fuel to the internal combustion engine, the fuel (pressurized by a low pressure fuel pump 4 and a high pressure fuel pump 5) from a fuel tank 3 as a fuel supply source is once stored, and the stored fuel is supplied via the connection parts 61c-f to the fuel injection valves 2a-d. In a space part 61a storing the fuel, a shaft 62 as an insertion member is provided for reducing the capacity of the space part 61a. Thus, the capacity of the space part of the delivery pipe 6-1 located ranging from the high pressure fuel pump 5 to each of the fuel injection valves 2a-d is reduced to reduce the capacity of the fuel which is pressurized by the high pressure fuel pump 5. This enables fuel pressurization supplied to the plurality of fuel injection valves 2a-d right after starting the engine. <P>COPYRIGHT: (C)2007,JPO&INPIT |
