摘要： The invention relates to a system for reducing emissions in catalytic converter exhaust systems for an internal combustion engine. The invention comprises air-fuel mixture forming means for providing a mixture of air-fuel to the engine, a catalytic converter for purifying an exhaust gas mixture from the engine, and a control unit adapted for controlling the mixture forming means so that an excess of hydrogen is generated in the exhaust gas mixture during the start-up of the engine. According to the invention, the excess of hydrogen is maintained essentially unburnt within the catalytic converter so as to provide a short light-off time for the catalytic converter.

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.
