ABSTRACT:
A fuel injection system for internal combustion engines which serves to inject fuel into the air intake tube of the engine. The fuel injection system includes at least one fuel injection valve, which is disposed in a holder body and communicates with a fuel supply line and a fuel discharge line. The fuel injection valve is provided with a fuel supply groove, from which fuel supply openings branch off, and a fuel discharge groove, from which the fuel discharge openings branch off with the fuel supply groove and fuel discharge groove being axially offset linearly from one another. The fuel injection valve is radially guided in the guide opening of the holder body by means of support bodies of a fuel filter, which extends axially over the fuel injection valve, covering the fuel supply groove and the fuel discharge groove. The supply of fuel from the fuel supply line is effected via one filter area to the fuel supply groove, while the fuel can flow out of the fuel discharge groove via another filter area of the fuel filter to the fuel discharge line. The central support body is embodied such that it seals off these filter areas from one another.
