  • FILTRATION OF GASOLINE DIRECT INJECTION ENGINE EXHAUSTS WITH HONEYCOMB FILTERS
    Publication number: 20150260064
    Abstract: Particulate matter is removed from the exhaust gas of a gasoline direct injection (GDI) engine, by introducing a particulate-containing exhaust gas into an inlet end of a ceramic honeycomb containing multiple axially-extending cells that are defined by intersecting porous walls, passing the exhaust gas through at least one such porous wall to trap the particulate matter in the porous wall, and then discharging the exhaust gas from an outlet end of the ceramic honeycomb. The porous walls of the ceramic honeycomb have a wall thickness of 150 to 750 ?m, the honeycomb has an effective permeability of at least 0.8 10-12.
