Abstract
A fuel evaporative emission control apparatus comprising a vessel having an adsorbent layer therein for adsorbing a vaporized fuel, and a vaporized fuel inlet conduit inserted in the adsorbent layer, wherein the improvement comprises a flow deflector of a hollow conical shape having a diameter gradually increasing upward, the deflector being embedded in the adsorbent layer, the vertical angle (.alpha.) of the flow deflector is adjusted to 60.degree. to 120.degree., the ratio (S1/S2) of the sectional area (S1) of the largest-diameter end portion of the flow deflector to the sectional area (S2) of the adsorbent layer is adjusted to 0.4 to 0.6, the ratio (a/b) of the distance (a) between the largest-diameter end portion of the flow deflector and the top end of the adsorbent layer to the distance (b) between the largest-diameter end portion of the flow deflector and the side end of the adsorbent layer is adjusted to at least 1.5, and the distance (a) is made smaller than the sum (g+b) of said distance (b) and the axial length (g) of the conduit in the adsorbent layer.
