<p> An evaporation fuel treating device capable of heating a more effective heating location of active carbon to increase a purge efficiency, restricting a rise in temperature of active carbon to prevent a decrease in adsorbing performance, and lowering power consumption. Since heating devices (16a), (16b) provided about midway between respective absorbing material layers (7a), (7b) in a canister (1) heat an adsorbing material (4) for a specified time before start of purging, heating a hard-to-purge location can promotes purging to enhance a purge efficiency and an adsorbing performance. A suspension of heating during purging restricts a rise in temperature of the adsorbing material (4) and prevents a decrease in adsorbing performance when an evaporation fuel is adsorbed.</p> |
