Abstract:
A module for the direct injection of fuel into the combustion chambers of multiple cylinders of an internal combustion engine, said module comprising:a body including means for mounting the body on a combustion chamber defining member of the engine; a fuel rail having a common fuel inlet passage extending longitudinally in the body and a plurality of longitudinally spaced laterally extending fuel feeder passages communicating with said inlet passage; an open ended mounting recess extending from each feeder passage, each recess defining an annular abutment adjacent its feeder passage; a direct acting fuel injector having an inlet end sealingly received in each recess and spaced from said abutment; and a loading spring disposed in each mounting recess and compressible between its respective abutment and the associated injector inlet end for loading the injector against a seat of the combustion chamber defining member for holding the injector on the seat against the force of combustion pressures acting on the injector from the combustion chamber during engine operation.
