PURPOSE:To introduce the heated atmosphere in the removal of a canister for improving efficiency by providing a heat exchanging means for exchanging heat between the atmosphere introduced into an atmospheric port and heat from an engine. CONSTITUTION:Fuel from a tank T and a float chamber C in the adsorption is adsorbed to a canister 10. Electric current shown by the arrow of solid line is produced in the removal of the canister by negative pressure in an intake pipe I, and adsorbed fuel in the canister is sucked into an engine. Then removed air is introduced into an atmospheric port 34 of the canister through a pipe 40', a heat exchanger 39, a temperature controlling valve 44 and a check ball, while it contacts the wall surface of an exhaust manifold in passing through the heat exchanger 39 to be subjected to the heat exchange and heating action. |
