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.
