Abstract
A fuel vapor storage and recovery apparatus for a fuel system of a motor vehicle including an internal combustion engine with an exhaust pipe and a fuel tank containing a fuel vapor/air mixture above a liquid fuel, the exhaust pipe being close to the fuel tank. The apparatus includes a vapor storage canister including a fuel vapor adsorbent material therein, a thermal insulation mechanism for thermally insulating at least a portion of the fuel tank from the heat generated by the exhaust pipe, and a beat exchanger. The heat exchanger is configured to heat to a purge temperature air guided there through by absorbing heat from the thermal insulation mechanism.

A fuel vapor storage and recovery apparatus for a fuel system of a motor vehicle including an internal combustion engine with an exhaust pipe and a fuel tank containing a fuel vapor/air mixture above a liquid fuel, the exhaust pipe being close to the fuel tank, the apparatus comprising:
- a vapor storage canister including fuel vapor adsorbent material therein;
- thermal insulation means for thermally insulating at least a portion of the fuel tank from heat generated by the exhaust pipe;
- a heat exchanger, and
- means for supplying air from said heat exchanger to said vapor storage canister,
- wherein the heat exchanger is configured to heat to a purge temperature air guided there through by absorbing heat from the thermal insulation means, and wherein the canister is a piece separate from the heat exchanger and/or thermal insulation means, and the canister is located away from the exhaust pipes,
- wherein the heat exchanger is either located between the fuel tank and the thermal insulation means, or integrated to the thermal insulation means.
