An evaporative emissions control system for reducing the amount of fuel vapor emitted from a vehicle, said vehicle having an engine with an air intake passage and a fuel system, said control system comprising: a canister having a purge port, a tank port, and a vent port in communication with a sorbent material disposed within said canister, said purge port configured to communicate with said air intake passage via a purge valve, said tank port configured to convey a mixture of air and said fuel vapor between said fuel system and said canister, and said vent port configured to communicate with atmosphere through a vent valve; and a cartridge heater at least partially disposed within said canister, wherein said heater is disposed in direct physical contact with said sorbent material so as to allow heat conduction from said heater to said sorbent material, wherein electrical power is conveyed from said vehicle to said heater through electrical terminals extending from said heater and disposed external to said canister during at least one predetermined time interval to heat said sorbent material when said control system is operated in a regenerative phase of operation; such that said control system: (a) during a storage phase of operation, allows flow of said mixture from said fuel system through said tank port into said canister wherein said sorbent material adsorbs a percentage of said fuel vapor then through said vent port and said vent valve to atmosphere, and (b) during said regenerative phase, allows air drawn in from atmosphere to flow through said vent valve and said vent port into said canister to desorb said fuel vapor from said sorbent material, with said desorbed fuel vapor then being drawn out through said purge port into said air intake passage by said engine, wherein the evaporative emissions control system further comprises a heat sink in direct physical contact with the heater and disposed within said canister, characterised inn that the heater is inserted through a first opening defined in the heat sink, the heater and the heat sink are configured such that the fit between the heat sink and the heater is a press fit and, and a portion of said heat sink is affixed to an attachment feature defined in the interior of the canister. a canister having a purge port, a tank port, and a vent port in communication with a sorbent material disposed within said canister, said purge port configured to communicate with said air intake passage via a purge valve, said tank port configured to convey a mixture of air and said fuel vapor between said fuel system and said canister, and said vent port configured to communicate with atmosphere through a vent valve; and a cartridge heater at least partially disposed within said canister, wherein said heater is disposed in direct physical contact with said sorbent material so as to allow heat conduction from said heater to said sorbent material, wherein electrical power is conveyed from said vehicle to said heater through electrical terminals extending from said heater and disposed external to said canister during at least one predetermined time interval to heat said sorbent material when said control system is operated in a regenerative phase of operation; such that said control system: (a) during a storage phase of operation, allows flow of said mixture from said fuel system through said tank port into said canister wherein said sorbent material adsorbs a percentage of said fuel vapor then through said vent port and said vent valve to atmosphere, and (b) during said regenerative phase, allows air drawn in from atmosphere to flow through said vent valve and said vent port into said canister to desorb said fuel vapor from said sorbent material, with said desorbed fuel vapor then being drawn out through said purge port into said air intake passage by said engine, (a) during a storage phase of operation, allows flow of said mixture from said fuel system through said tank port into said canister wherein said sorbent material adsorbs a percentage of said fuel vapor then through said vent port and said vent valve to atmosphere, and (b) during said regenerative phase, allows air drawn in from atmosphere to flow through said vent valve and said vent port into said canister to desorb said fuel vapor from said sorbent material, with said desorbed fuel vapor then being drawn out through said purge port into said air intake passage by said engine, wherein the evaporative emissions control system further comprises a heat sink in direct physical contact with the heater and disposed within said canister, characterised inn that the heater is inserted through a first opening defined in the heat sink, the heater and the heat sink are configured such that the fit between the heat sink and the heater is a press fit and, and a portion of said heat sink is affixed to an attachment feature defined in the interior of the canister.
