摘要： In an internal combustion engine, a sulfur detection sample gas is generated in a sample gas generation chamber (14) by fuel of an amount smaller than the amount of fuel fed to a combustion chamber (2) and proportional to the amount of fuel fed to the combustion chamber (2). An SO X sensor (16) having a sensor part trapping the sulfur contained in the sample gas and capable of detecting the amount of sulfur trapped in the sensor part from the property changes of the sensor part is provided. The amount of SO X that flows into the catalyst (8) is estimated from the output value of this SO X sensor (16).

摘要： The present invention relates to a regenerable catalyst composition suitable for entrapping SOx, a Diesel oxidation catalyst (DOC) or a catalyzed soot filter (CSF) comprising said catalyst composition. The invention furthermore relates to the use of said catalyst composition for adsorbing SOx as metal sulfate under lean conditions and desorbing accumulated SOx as SO2 under rich conditions. Such reversible SOx trap material is able to work under typical NOx trap operating conditions to prevent sulfur poisoning of NOx trap and can be regenerated under rich conditions of NOx trap operation at 300-450 DEG C. The platinum group metal free (PGM-free) regenerable catalyst composition substrate is suitable for entrapping SOx having the general structure Cu/ A oxide whereby A oxide represents SiO2, Zr-SiO2, Al2O3, TiO2-Al2O3, ZrO2 and In2O3 and mixtures thereof. For irreversible SOx trap, which can collect SOx under lean conditions and can be regenerated only at elevated temperatures in a separate mode of operation, the systems containing praseodymia, zirconiapraseodymia and mixed manganese-yttria and mixtures thereof have shown to be an effective material for SOx removal.

摘要： In an internal combustion engine, the engine is formed so that an output of an electric motor (27) can be superposed on an output of the engine. An SO X trap catalyst (13) able to trap the SO X contained in the exhaust gas is arranged inside the engine exhaust passage upstream of the NO X storage catalyst (14). The vehicle drive power from the engine and the vehicle drive power from the electric motor (27) are adjusted so that the SO X trap rate of the SO X trap catalyst (13) is maintained at a predetermined high SO X trap rate.
