Abstract

A fuel injection system includes a substantial integration of various components, the fuel injection system including at least one fuel injector and at least one intake manifold, as well as a fuel supply channel, which are all surrounded by a plastic sheathing. The full integration of the fuel injectors into an induction pipe component made of plastic leads to the reduction or elimination of both electrical and hydraulic interfaces. Thus, only a compact component remains that is very simple to attach to a cylinder head of an internal combustion engine. Means for electrically contacting the fuel injectors (1), such as connector sockets, are also fully integrated in the plastic sheathing. This fuel injection system is especially suited for use in mixture-compressing internal combustion engines having externally supplied ignition.
