METHOD FOR DETECTING ABNORMALLY FREQUENT DIESEL PARTICULATE FILTER REGENERATION, ENGINE AND EXHAUST AFTERTREATMENT SYSTEM, AND WARNING SYSTEM AND METHOD |
摘要 |
A method is provided for detecting abnormally frequent diesel particulate filter (DPF) regeneration. The method includes measuring a pressure drop across the DPF and using the measured pressure drop to calculate a pressure drop based soot load estimate, calculating soot output from an engine model and using the calculated soot output to calculate an emissions based soot load estimate, comparing the pressure drop based soot load estimate with the emissions based soot load estimate, and providing a warning if a difference between the pressure drop based soot load estimate and the emissions based soot load estimate exceeds a predetermined |
