Apparatus for the purification of exhaust gases from internal combustion engines is disclosed including a conduit for connecting the exhaust pipe from the engine with a canister containing an adsorbent for at least one of the components of the exhaust gases, and a valve associated with the conduit for selectively directing the exhaust gases from the exhaust pipe to the canister when the valve is open. Methods for purification of such exhaust gases are also disclosed including monitoring an operating condition for the internal combustion engine and controlling the flow of the exhaust gases from the engine to the exhaust pipe in response to the monitored operating condition, controlling of the flow including selectively directing at least a portion of the exhaust gases from the exhaust pipe to the canister.

[ What is claimed is:] [1.] Apparatus for the purification of exhaust gases from an internal combustion engine including an exhaust pipe for transporting said exhaust gases from said internal combustion engine and a canister containing an adsorbent for at least one component of said exhaust gases, said apparatus comprising a first conduit for connecting said exhaust pipe with said canister, a first controllable valve associated with said first conduit for selectively directing said exhaust gases from said exhaust pipe to said canister when said valve is open and a controller for said first controllable valve, wherein said controller selectively controls said first controllable valve between a first condition wherein at least a portion of said exhaust gases are directed to said canister and a second condition wherein said exhaust gases are directed to the atmosphere through said exhaust pipe.
