Abstract (en)
The invention relates to a canister for evaporated fuel processing system, having a number of adsorbing chambers, wherein the last chamber 10 is connected with an atmospheric port 7 and comprises a monolithically formed block 12 of activated carbon. The block 12 is surrounded, at least from its atmospheric port 7 side by plastic, advantageously polyurethane, covering 13. Preferably, the block 12 is distanced from the atmospheric port 7 side of the last adsorbing chamber 10, defining an improved purge zone 15. The invention also relates to a method of manufacturing such a canister, where, after positioning the block of activated carbon inside the last adsorbing chamber, a covering surrounding the block is formed by injecting plastic, preferably polyurethane foam, into a space between the outer casing of the block and the inner casing of the chamber.
