Abstract:
A method of fabricating an engine fuel rail comprising the steps of:integrally molding a fuel delivery pipe from a synthetic resin by means of a primary molding, the fuel delivery pipe being provided with a plurality of openings to serve as fixture mounts for respective injectors, the openings being branched from a fuel delivery path disposed on the right side and the left side of the fuel delivery path, alternatively;forming an electrical wiring by applying press working to a metal sheet;securely holding the electrical wiring with a plurality of reinforcement blocks by insert molding with synthetic resin; andmolding the fuel delivery pipe integrally with the electrical wiring in a base member of the engine fuel rail with synthetic resin by means of a secondary molding, whereby the base member is provided with an opening at one end thereof to serve as a socket on an input side for the electrical wiring, and is provided with a plurality of branching blocks formed integrally therewith at the side thereof, each branching block having both an opening to serve as the fixture mount for the respective injectors and an opening to serve as a socket on an output side for the electrical wiring.
