Abstract
A fuel vapor processing apparatus may include a first adsorption chamber, a second adsorption chamber and a third adsorption chamber that are connected in series with respect to a flow of gas. A ratio of a length to a diameter of the second adsorption chamber may be larger than that of the first adsorption chamber. A cross sectional area of each of the second and third adsorption chambers may be smaller than a cross sectional area of the first adsorption chamber.
