Abstract (en)
[origin: EP1150002A1] The fuel injection system (1) for an internal combustion engine consists of a pre-fabricated unit including a common rail (6) and the injectors consisting of electromagnetically operated valves (2). Between the valves and the common rail pipes (10) are arranged which are flexible but sealingly connected at their one end to the common rail and the other end to the valves. Preferably between the common rail and the pipes plate springs (11) are arranged to keep the injection valves pressed against the seat in the cylinder head. By using the intermediate pipes with sealings (18,18') at both ends and the stack of plate springs (11), the manufacturing tolerances for the bores in the cylinder heads and for the independently fabricated bores in the common rail can be compensated. <IMAGE>
