Abstract
A known fuel distributor, which has continuous valve receptacle openings for fuel injection valves. The fuel distributor prevents vapor bubbles that cause difficulties in engine starting to form. The novel fuel distributor has a fuel supply line split by a partition into a first conduit and a second conduit; the second conduit serves as a reservoir and communicates both with the first conduit, through a through opening, and with the various valve receptacle openings. In the fuel reservoir, fuel free of vapor bubbles can collect after the shutoff of the hot engine; upon hot starting of the engine, this makes it possible to inject fuel that is free of vapor bubbles and is readily ignitable through the fuel injection valves. The fuel distributor according to the invention is especially well-suited for fuel injection systems of mixture-compressing internal combustion engines with externally supplied ignition.
