| 摘要 |
A system and method for controlling soot regeneration in a catalyst soot filter ("CSF") of an exhaust system for a diesel engine by measuring the inlet temperature of a diesel oxidation catalyst ("DOC") coupled to the CSF, determining a target light off temperature for the DOC, injecting a first fuel amount into a cylinder of the engine to cause the DOC inlet temperature to approach the target light off temperature, measuring the CSF inlet temperature and pressure across the CSF, determining a target CSF inlet temperature for regeneration, injecting a second fuel amount for combustion in the DOC to cause the CSF inlet temperature to approach the target CSF inlet temperature. |
