ABSTRACT:
A fuel vapor control system that is adapted for use with internal combustion engines includes a fuel tank, an evaporative emission control device containing activated carbon and including a first orifice that fluidly communicates with the fuel tank via a vent line. A second orifice in the control device is open to the atmosphere. A purge tube is between a filter element and a venturi section of the engine and fluidly communicates with a third orifice in the control device via a vapor line. Fuel vapors are absorbed by the activated carbon when the engine is not running, and the carbon releases the fuel vapors to the engine via the purge tube when the engine is running.
