To control engine intake evaporative emissions, or “breathing losses”, functions of both Fuel Vapor Storage and Air Induction Systems must be understood. The merging of these diverse systems results in a functional requirements set that is very broad in scope. Several known devices for controlling engine evaporative emissions breathing losses are reviewed and compared. Experimental methods of measuring and estimating hydrocarbon adsorption, approximated by n-butane, are shown, some utilizing scaled laboratory sample units. HC capture efficiency, capacity, flow losses and other performance characteristics of the various devices are then optimally matched to the numerous system needs. Thus, emission control requirements are met, while cost and deleterious effects are minimized, resulting in high level optimal systems.
