Abstract
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.
