Abstract:
An engine intake manifold, said manifold comprising:a plurality of air intake passages adapted for communication with associated engine cylinder inlet ports;a plurality of drop-through injector pockets formed in the manifold, each of the pockets communicating at one end with an associated one of the air intake passages and open at an opposite second end for receiving and operation with a side feed fuel injector;at least one common fuel passage acting as a fuel rail formed integral with said manifold and communicating with a plurality of said injector pockets adjacent their second ends for supplying fuel to said pockets and adapted to supply fuel to inlets of associated side feed fuel injectors when received in said pockets;a side feed injector in each of said pockets and having opposite nozzle and connector ends, said nozzle ends extending into said one end of each pocket, electrical connectors on said connector ends adjacent said second end of each pocket, and at least one side feed opening in each injector spaced toward said connected end and communicating the common fuel passage of the manifold with the interior of the injector and with an axially centered central fuel passage through the injector leading to said nozzle end;wherein said central fuel passage of each injector extends from said side inlet through the center of an electrical actuating coil and an associated armature connected with a nozzle valve adjacent the nozzle end of each injector.
