Abstract
The present invention is accomplished by a canister structure for an internal combustion engine that includes a container having a gas passage therein through which gas containing evaporative fuel flows from a first end to a second end, a purge portion disposed on the container and connected to the first end through which vacuum pressure is applied into the gas passage, a charge portion disposed on the container and connected to the first end through which the gas is introduced into the gas passage, a drain portion disposed on the container and connected to the second end through which the gas passage is made open to the atmosphere, and an adsorbent material, disposed in the gas passage, to temporarily adsorb the evaporative fuel, whose specific heat on the side of the second end is made higher relative to that on the side of the first end.
