Abstract
A fuel vapor processing apparatus may include a first adsorption chamber, a second adsorption chamber and a third adsorption chamber that are arranged 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 a ratio of a length to a diameter of the first adsorption chamber. A filling ratio of an adsorbent within the second adsorption chamber may be smaller than a filling ratio of an adsorbent within the first adsorption chamber.
