摘要： Exhaust systems and components are suitable for use with gasoline engines to capture particulates and to reduce gaseous emissions, where three-way conversion (TWC) catalysts located on a particulate filters are provided. Coated particle filters having washcoat loadings in the range of 1 to 4 g/ft3 result in minimal impact on back pressure while simultaneously providing TWC catalytic activity and particle trapping functionality to meet increasingly stringent regulations such as Euro 6. Sufficient to high levels of oxygen storage components (OSC) are also delivered on and/or within the filter. The filters can have a coated porosity that is substantially the same as its uncoated porosity. The TWC catalytic material can comprise a particle size distribution such that a first set of particles has a first d90 particle size of 7.5 μm or less and a second set of particles has a second d90 particle size of more than 7.5 μm.
