Abstract

PURPOSE:To prevent adsorbent from being broken due to vibration by placing the adsorbent, which traps evaporated fuel from fuel supply, in gas-permeable elastic foamed material. CONSTITUTION:Polyurethane foam having three dimentional skelton structure containing in their space active carbon particles 7 is compressed by grids 9, 10, and filled in an evaporated fuel trap unit 1. Evaporated fuel from fuel tank 2 passes through rout 3, the grid 9 in the unit 1, is distributed in the polyurethane foam, and adsorbed by the active carbon particles 7. The remaining gas is discharged through outlet 6. When suck route 4 becomes negative pressure, atmospheric air is sucked from the outlet 6, separates the evaporated fuel deposited on the active carbon particles 7, and the mixed air-fuel flows through route 5 to enter the suck pipe 4, and is combusted in an internal combustion engine.
