ABSTRACT:
A fuel vapor treating apparatus for an engine provided with a fuel tank and a canister is disclosed. The fuel tank is communicated with the canister by a vapor line and a breather line. The canister has a partition which defines a main chamber and a sub-chamber therein. A plate provided in the sub-chamber further defines two compartments therein. The plate has a plurality of holes on its entire surface. When fuel vapor flows through the holes, fuel components suspended in the fuel vapor are adsorbed and collected by an adsorbent. The adsorbent pellets of the two compartments divided by the partition are kept from contacting each other. This suppresses diffusion of the fuel vapor between the upper and lower chambers. The total area of the holes on the plate is greater than the passage area of the breather line. Accordingly, the venting resistance of the plate is relatively low. Thus, the venting resistance inside the canister is relatively low.
