Method of operating a selective catalytic reduction on filter of an automotive system
A method of operating a Selective Catalytic Reduction on Diesel Particulate Filter or SDPF is disclosed. During a SDPF regeneration; temperature values are obtained for the SDPF inlet and SDPF outlet. The temperature values are used to calculate a rate of increase of SDPF outlet temperature and a ra...

| description | A method of operating a Selective Catalytic Reduction on Diesel Particulate Filter or SDPF is disclosed. During a SDPF regeneration; temperature values are obtained for the SDPF inlet and SDPF outlet. The temperature values are used to calculate a rate of increase of SDPF outlet temperature and a rate of increase of SDPF inlet temperature. A ratio between the rate of increase of SDPF outlet temperature values and the rate of increase of SDPF inlet temperature values is calculated, and if the ratio is greater than a threshold thereof, the exhaust gas composition is modified in some manner. |
