An evaporative emission control system for an automotive vehicle includes a generally cylindrical casing having an adsorption zone containing hydrocarbon adsorbing agent, an antechamber extending within the casing to the adsorption zone, and a swirl inducing inlet passage for conduction of hydrocarbon laden air into the antechamber such that a rotational flow pattern will be established in the antechamber, with the rotational flow having an axis coincident with a longitudinal axis of the generally cylindrical casing.

[ We claim:] [1.] An evaporative emissions control system for an automotive vehicle, comprising:a generally cylindrical casing having an adsorption zone with a hydrocarbon adsorbing agent contained therein;an antechamber extending within said casing from a first end of the casing to the adsorption zone, with a planar interface between the adsorption zone and the antechamber; anda swirl inducing, tangentially directed inlet passage for conducting hydrocarbon laden air into the antechamber with an even rotational flow such that a mixed rotational and axial flow pattern having a substantially invariant axial flow velocity distribution is established across the planar interface.
