摘要： 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.

摘要： The invention relates to a device and a method for reducing emissions in catalytic converter exhaust systems for a vehicle provided with a combustion engine. The invention comprises a control unit adapted to control the air-fuel being fed to the engine so that a high concentration of hydrogen is generated in the exhaust gas during start-up of the engine. Furthermore, secondary air is supplied downstream of the engine during cold starting thereof for forming a gas mixture with the exhaust gas. This gas mixture is oxidized, so that heat energy generated by means of this oxidation is supplied to the catalyst, thereby providing a reduction of the light-off time of the catalyst.

摘要： Method and device for reduction of a gas component in an exhaust gas flow of a combustion engine (1) that is adapted for operation by a lean air/fuel mixture. An exhaust pipe (21) is included for transport of the exhaust gas flow from the engine (1). A separation unit (22) is also included that is arranged along the exhaust pipe (21), which separation unit (22) has a wall structure (32) of a material which provides separation of the gas component from the exhaust gas flow by means of a selective passage of the gas component before other gas components in the exhaust gas flow. The method provides for a reduction and a separation unit that is intended to be utilized during such a reduction. An improved reduction of in particular NOx compounds from a so-called “lean-burn” engine is also provided.
