An exhaust turbine for an internal combustion engine, which may either serve as a compressor for turbocharging or a turbogenerator for a hybrid vehicle, has its turbine surfaces and the internal surfaces of the exhaust turbine housing coated with a catalyst so the exhaust gases are treated to catalytic conversion as they pass through the exhaust turbine. The turbine wheel is equipped with a disk-like slinger at its input end that carries particulate matter in the exhaust outward radially into a particulate trap and combustion chamber formed on the interior of the turbine housing. The combustion chamber is heated by the exhaust gases and artificial heating such as electrical heating may be used to preheat the chamber. The combustion products from the burned particulate matter are added to the exhaust.
