Abstract
A diesel particulate filter assembly having a housing and a filter structure disposed within the housing for trapping particulate material in received exhaust gas as such received exhaust gas passes through the housing along a longitudinal axis of the housing. The filter structure has walls of particulate collecting, gas passing material. The walls pass portions of the exhaust gas while trapping particulate material in such passing exhaust gas. The walls are disposed the oblique to the direction of the received exhaust gas.
Claims7
A diesel particulate filter assembly, comprising:
- a housing;
- a filter structure disposed within the housing for trapping particulate material in received exhaust gas as such received exhaust gas passes through the housing along a longitudinal axis of the housing, such filter structure having walls of particulate collecting, gas passing material, such walls passing portions of the exhaust gas while trapping particulate material in such passing exhaust gas, the walls being disposed oblique to the direction of the received exhaust gas.
A diesel particulate filter assembly, comprising:
- a housing;
- a filter structure disposed within the housing for trapping particulate material in received exhaust gas as such received exhaust gas passes through the housing along a longitudinal axis of the housing, such filter structure forming a plurality of channels separated by walls of particulate collecting, gas passing material, such walls passing portions of the exhaust gas from one of the channels to another adjacent one of the channels while trapping particulate material in such passing exhaust gas, the walls being disposed oblique to the direction of the received exhaust gas.
A diesel particulate filter assembly, comprising:
- a housing having an inlet for receiving an inlet flow of exhaust gas from a diesel engine;
- a filter structure disposed within the housing for trapping particulate material in the received exhaust gas as such received exhaust gas passes in an outlet flow through an outlet of the housing with the inlet flow and the outlet flow being disposed along a longitudinal axis of the housing, such filter structure forming a plurality of channels for passing portions of the received exhaust gas, such channels being separated by porous walls of particulate collecting, gas passing material, such walls passing portions of the exhaust gas from one of the channels to another adjacent one of the channels while trapping particulate material in such passing exhaust gas, the separating walls of each one of such channels the walls being disposed oblique to the direction of the received exhaust gas.
