Patent ID: 8375925

Claim:
A vaporized fuel processing device comprising: an adsorption material within a canister and configured to temporarily hold vaporized fuel generated in a fuel tank in the adsorption material within the canister, the canister into which an intake air pressure of an engine used for purge air is introduced when the engine is operated and purge air purging fuel corresponding to vaporized fuel from the adsorption material is to be supplied to the engine; an electric heater configured to heat the adsorption material; and a control section configured to variably control an electric power supplied to the electric heater in accordance with a purge air quantity to be introduced within the canister, wherein the control section includes: a flap arranged to interrupt a flow passage of the purge air within the canister; and a variable resistor intervened in an electric circuit in order for an electric power to be supplied to the electric heater to vary, an electrical resistance of the variable resistor varying in accordance with a position of the flap, and wherein the electrical resistance of the variable resistor is decreased along with an increase in the electric power.
