Carbon heating element for evaporative emission canister

摘要

An evaporative emissions control system for reducing the amount of fuel vapor emitted from a vehicle (11) includes a canister (110) containing a sorbent material (128) and a cartridge heater (140) disposed at least partially within the canister (110) in direct contact with the sorbent material (128). Electrical terminals (142) for applying power to a heating element within the heater (140) are disposed external to the canister (110). At least one heat sink (144) may be included within the canister (110) in direct contact with the heater (140). A method of manufacturing an evaporative emission control system that includes a cartridge heater (140) disposed in a canister (110) is also presented.
