    摘要： An integrated air fuel module (10) for an internal combustion engine reduces or eliminates the escape of hydrocarbon evaporative emissions from the integrated air fuel module (10) system, sub systems and components. The integrated air fuel module (10) includes containment means (34), such as a valve (34) or carbon adsorber, that blocks the escape of evaporated hydrocarbon emissions from the air inlet (16) of an engine during engine off conditions. The module (10) provides a reduced number of potential external hydrocarbon leak and permeation paths to the surrounding atmosphere. Preferred geometries of the intake manifold (12) in the module (10) with the internal integration of other normally external systems, such as fuel injection (60) and positive crankcase ventilation (50) systems, accomplish the containment of evaporative emissions within or entering the air fuel module (10) between engine operating periods when the engine is shut down.

    摘要： A fuel delivery module integrates a fuel rail, with its associated connections, features and components, with the injectors for one bank of a direct injection engine. When the module is secured to the engine, loading springs between the inlet ends of the injectors and abutments in the mounting recesses accommodate variations in manufacturing and assembly tolerances to provide adequate but not excessive loading of the injectors against associated seats of the engine. Manufacturing and assembly costs are reduced by the use a module with injectors pre-installed. Also, the module may be pretested in a suitable test fixture prior to installation to assure proper flow and spray development from each of the injectors. The module may integrate other components also, such as intake air passages, EGR passages and coolant passages and their associated components. Various examples of injector loading springs are described.
