摘要： The invention relates to a method for purifying exhaust gas in an internal combustion engine provided with an LNT and a particulate matter filter arranged in an exhaust gas conduit of the engine. The method includes de-sulfurization of the LNT and regeneration of the particulate matter filter. The invention includes the following steps: initiating a heating phase wherein the engine is set to generate heat sufficient for the de-sulfurization and the regeneration; initiating a de-sulfurization phase during a first time period (t1), in which the engine is set to generate a rich exhaust gas in the exhaust gas conduit; keeping the first time period below a first maximum value so as to avoid release of emissions of H2S from the engine; initiating a regeneration phase during a second time period, in which the engine is set to generate a lean exhaust gas in the exhaust gas conduit; keeping the second time period below a second maximum value so as to avoid thermal damage to the particulate matter filter; and repeating the de-sulfurization phase and the regeneration phase in a periodical manner.

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： 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.
