Article Synopsis
- Recent PM emission standards have led to increased use of diesel particulate filters (DPFs), which must be periodically regenerated to eliminate trapped particulate matter.
- Our study involved both active and passive regeneration of two heavy-duty diesel vehicles, analyzing emissions during these events and the efficiency of PM conversion to gas-phase products.
- Findings showed that while DPFs reduce PM emissions during normal operation, the emissions produced during regeneration events may vary widely, suggesting challenges in effectively designing engines to minimize emissions across differing real-world driving conditions.
