  • a conventional fuel supply pipe structure in a throttle body provided with two fuel injection valves is disclosed in Fig. 2 .
  • Reference numeral 30 denotes a throttle body in which an intake passage 31 is provided in an inner portion so as to laterally pass through.
  • the intake passage 31 is opened and closed by a throttle valve 33 attached to a throttle valve shaft 32, and an auxiliary throttle valve 34 is attached to an auxiliary throttle valve shaft 35 in an upstream side of the throttle valve 33 so as to open and close the intake passage 31.
  • the throttle valve 33 controls an amount of air flowing to an internal combustion engine (not shown), and the auxiliary throttle valve 34 controls an amount of air flowing to the throttle valve 33.
  • Reference symbol J1 denotes a first fuel injection valve injecting and supplying fuel into an intake passage 31a at a downstream side of the throttle valve 33.
  • the first fuel injection valve J1 bears a fuel supply region at a time when the internal combustion engine is under a low opening degree operation and under a middle opening degree operation.
  • a leading end J1a of the first fuel injection valve J1 is inserted to a first insertion hole 30a of the throttle body 30, a rear end J1b is inserted to a first fuel injection valve insertion hole 36a of a first fuel distribution pipe 36, and the first fuel injection valve J1 is pinched by the throttle body 30 and the first fuel distribution pipe 36 screwed to the throttle body 30 by a screw 41.
  • a longitudinal axis Z-Z of the first fuel injection valve J1 is arranged at a crossing angle (A degree) with respect to a longitudinal axis X-X of the intake passage 31.
