Abstract
A fuel vapor processing apparatus may include a first canister and a second canister each having an adsorbent disposed therein. The second canister may include a first passage and a second passage each communicating between the first canister and an atmosphere. The first passage may be configured as an adsorption passage having the adsorbent disposed therein. The second passage may be configured as an air passage through which air flows. A control device may control flow of the air through the air passage. A heating device may heat the air flowing through the air passage. The air passage may be arranged so that the adsorbent of the adsorption chamber is heated by heat of the air that is heated by the heating device and flows through the air passage.
