Abstract

A four-pass carbon canister includes a cover sealingly coupled to an injection-molded housing having a first chamber, a second chamber fluidly coupled to the first chamber, a baffle fluidly coupled to the second chamber, and a third chamber fluidly coupled to the baffle. The three chambers are filled with carbon pellets to absorb carbon pellets provided to the carbon canister from the fuel tank. The carbon canister is periodically purged by drawing fresh air into the carbon canister, with the fresh air desorbing the hydrocarbons and then provided to and consumed in an internal combustion engine.
