Abstract
An evaporative fuel adsorbent 32, which adsorbs evaporative fuel, is positioned substantially parallel to a sidewall surface 30 of a surge tank 22. A retention member 34 is positioned between the sidewall surface 22 and evaporative fuel adsorbent 32 to prevent oil, which runs down on the sidewall surface 22, from adhering to the evaporative fuel adsorbent 32. The evaporative fuel adsorbent 32 is mounted on the sidewall surface 30 of the surge tank 22 via the retention member 34.
Claims5
An evaporative fuel adsorption device comprising:
- an evaporative fuel adsorbent disposed in an intake path to adsorb evaporative fuel;
- and
- oil adhesion prevention means that is positioned between an inner wall surface of said intake path and said evaporative fuel adsorbent to prevent oil running down on said inner wall surface from adhering to said evaporative fuel adsorbent;
- wherein said evaporative fuel adsorbent is mounted on said inner wall surface via said oil adhesion prevention means.
