Abstract
An apparatus for treating evaporated fuel gas from a fuel tank of a motor vehicle having an internal combustion engine. The fuel treating apparatus includes a means for sensing the amount of fuel gas vapors in the fuel tank, a means for drawing the fuel vapors into the intake of the engine and a means for varying the air/fuel ratio in the intake of the engine in response to the amount of fuel gas vapors sensed in the fuel tank by the sensing means whereby a rich air/fuel mixture in the intake of the engine is prevented.
