Abstract
A fuel vapor treating apparatus includes a canister, a purge pipe, a purge control valve, and a heating device. The canister is configured to store fuel vapor generated in a fuel tank. The purge pipe is configured to deliver the fuel vapor stored in the canister to an intake passage of an internal combustion engine together with air. The purge control valve is configured to be attached to the purge pipe to be selectively opened and closed in order to adjust a purge flow rate. The purge control valve is also configured to be opened based on a purge request that is made after the internal combustion engine is started. The heating device is configured to heat the purge control valve after the internal combustion engine is started and before the purge request is made.
