TARGETED PARTICULAR MATTER FILTER REGENERATION SYSTEM |
摘要 |
A regeneration system includes a particulate matter (PM) filter. The PM filter has an upstream end that receives an exhaust gas from an engine. An air pump circuit directs ambient air to a first exhaust conduit upstream from the PM filter. A control module determines a current soot loading level of the PM filter. The control module also at least one of operates the engine in a rich mode and activates an air pump of the air pump circuit when the current soot loading level is greater than a predetermined soot loading level. |
