Abstract
In an evaporative emission control system of a motor vehicle, a two way valve is provided for connecting the canister with the air-fuel mixture intake tube of the engine when assuming a first position and connecting the canister with the clean side of the air cleaner when assuming a second position. The two way valve assumes the first position when the interior condition of the fuel tank does not tend to saturate the vapor adsorbing power of the canister, and assumes the second position when the interior condition of the fuel tank tends to saturate the vapor adsorbing power of the canister.
