ABSTRACT:
A canister is divided into small and large bed portions, with the small portion being loaded separately with just diurnal vapors so that it can be purged with a greater efficiency. At fuel fill, both bed portions are loaded simultaneously with a proportion of fuel fill vapors keyed to their own volume ratio, so that an effective capacity equal to the sum of the two is achieved.
