Abstract
A fuel injection system for internal combustion engines having a plurality of fuel injection valves of the top-feed type and a fuel distributor, which has a distributor duct formed in a plastic housing and connecting branches, each of which accepts an end-face supply connection of an injection valve. For simplified manufacture and assembly and in order to secure the injection valves against radial twist, electrical plug jacks are integrated in the plastic housing of the fuel distributor to accept corresponding electrical plug elements of the injection valves. Two of the plug jacks are associated in each case with one of the connecting branches in such a way that when the injection valve is pushed into the connecting branch the plug elements simultaneously penetrate into the associated plug jacks. All the plug jacks are electrically connected to a multi-pole connecting plug located on the fuel distributor, and the electronic control unit for controlling the injection valves is connected to the multi-pole connecting plug.
