Abstract:
1. A fuel distribution pipe structure for a plurality of throttle bodies wherein each of said bodies is provided with a fuel injection valve and said bodies are arranged in a position separated from each other by a given distance, and fuel is supplied to each of said fuel injection valves from a fuel distribution pipe, said fuel distribution pipe structure comprising: a distribution member detachably supported between a first throttle body and a second throttle body, first and second injection valve support members detachably coupled between a first side wall of said first throttle body and a second side wall of said second throttle body; wherein said distribution member is provided with a first flat surface and a second flat surface, said first and second surfaces of the distribution member being parallel to each other, and said distribution member is provided with a fuel distribution path, throttle body mounting holes, and injection valve support member mounting holes, said distribution path, throttle body mounting holes and valve support member mounting holes each extending from said first fiat surface to said second flat surface of the distribution member, said distribution member having a fuel inflow boss, said fuel distribution path in communication with a fuel inflow path of the fuel inflow boss; wherein each of said injection valve support members is provided with a first flat surface and a second flat surface, said first and second surfaces of the injection valve support members are parallel to each other; each injection valve support member is provided with mounting thread holes extending from said first fiat surface of the injection valve support member to said second flat surface of the injection valve support member and with an injection valve support boss extending diagonally away from said second flat surface of the injection valve support member; wherein each injection valve support boss is provided with a fuel supply path extending in a longitudinal direction thereof, one end of said fuel supply path is open at said second flat surface and the other end of said fuel supply path is connected to an injection valve support hole which is open at a lower end of said injection valve support boss; wherein each injection valve support member is mounted respectively on each flat surface of said distribution member so that said fuel distribution path in said distribution member is in communication with each of the fuel supply paths in the injection valve support members; wherein bolts are inserted into said mounting thread holes in said distribution member and said mounting thread holes in each injection valve support member so that each injection valve support member is secured to each flat surface of said distribution member; and wherein first and second fuel injection valves and provided on said first and second throttle bodies and are coupled to said first and second injection valve support members, respectively.
