An emissions control canister including an insert having an elongate well and flange. The insert extends into a chamber such that a carbon adsorption column is a hollow cylinder around the insert. After vapors flow through the column of adsorbent, flow is directed through holes in the flange and out through an atmosphere port. The flow path through the hollow cylinder has an increased L/D ratio and improves emission performance. In a second embodiment, a cylindrical tube surrounds the exit port and extends into the insert, forcing vapor flow along a tortuous path between the cylindrical wall and the insert. In a third embodiment, a final scrubber is added inside the tube.

Evaporative emissions canister having an internal insert

A canister for an evaporative emissions control system that comprises a canister package with an interchangeable cartridge. The specific cartridge selected for use in the canister package is determined primarily based upon emissions regulatory requirements of the device that uses the canister. The need for a common canister package with an interchangeable cartridge simplifies packaging and assembly of the canister into any device, whether a vehicle or a stationary device, or a handheld tool. For example, a common canister package reduces need for testing, development and certification associated with use of multiple canister packages on a common vehicle platform.
