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