摘要:
An apparatus for treating fuel vapor, such as in a motor vehicle fuel tank, by subjecting it to adsorption treatment to prevent its direct emission into the atmosphere. The apparatus according to the present invention comprises a fuel tank, a partitioning wall provided within the fuel tank to define a small fuel storage chamber within the fuel tank, a canister container housed in the small fuel storage chamber, the canister container storing therein a fuel adsorbing material. When fuel feeding takes place, feeding fuel is introduced into the small fuel storage chamber to cool the canister container. However, when the engine is operated, high temperature return fuel is introduced into the small storage chamber to heat the canister container thereby promoting the adsorbing and de-adsorbing action of fuel by the fuel adsorbing material.
