Modular fuel injection pack

摘要

Steel fuel rails are provided with the mechanical components of a plurality of fuel injector valve bodies. The electronics for operating those valves are molded into an injector pack. The valve bodies are inserted into the passages associated with the injector pack such that the electronics are part of a single molded plastic portion. A corrugated seal is sealed to an outer portion of the passage on the injector pack. Thus, the present invention eliminates the number of connections for supplying fuel that needed to be sealed in the prior art. Further, the number of required assembly steps is reduced over the prior art.
