Fuel rail for bottom and side fed injectors

An internal combustion engine fuel rail assembly comprising a rail member which contains a fuel hole via which fuel is made available to a plurality of electrically operated fuel injectors mounted on said rail member, each of said fuel injectors comprising a fuel inlet, a fuel outlet, and an electrical connector, said fuel inlet being intermediate opposite axial ends of the fuel injector, said fuel outlet being disposed toward one of said axial ends relative to said fuel inlet, and said electrical connector being disposed toward the other of said axial ends relative to said fuel inlet, said rail member comprising transverse through-hole structures that are spaced apart along the length of said rail member and whose own lengths are arranged transverse to the length of said rail member, each of said fuel injectors being disposed in a corresponding one of said through-hole structures such that the injector's inlet is communicated with said fuel hole via an opening between the corresponding through-hole structure and said fuel hole, said rail member also containing electrical conductors extending from an input connector to individual receptacles for each fuel injector, each such receptacle being open in a direction that faces the electrical connector of the corresponding fuel injector, and said electrical connector of each fuel injector being open in a direction facing the corresponding receptacle and mated with the corresponding receptacle to establish electrical connection of the fuel injector to said input connector, wherein each said fuel injector comprises catch means that is engaged with a corresponding catch-receiving means in said rail member adjacent each through-hole structure, in which each said catch-receiving means comprises hole means, and in which each said catch means comprises at least one integral catch on each fuel injector, and each said hole means comprises a corresponding hole within which each such catch is received, each such catch comprising a hook that lodges behind a surface that lies adjacent the corresponding hole.
