Abstract: An automotive evaporative emissions canister includes a housing containing a hydrocarbon adsorbing material, such as carbon. The canister includes a vent port for venting air to the atmosphere upon adsorption of hydrocarbons and for admitting air upon the desorption of hydrocarbon during the purging operation of the canister. A purge port is adapted for connection to the engine to allow the desorbed hydrocarbons to flow into the engine. A plurality of holes is formed through the side wall of the canister housing and are formed at a location remote from the purge port between the vent port and the purge port to define a buffer zone. The holes are adapted for communication with the fuel tank to allow fuel vapor to flow through the tank through the plurality of holes into the buffer zone. Thus, vapor purged directly from the tank to the engine is buffered through the carbon canister to prevent any vapor purge spikes creating the undesirably over-rich condition.
