Overview of Common Problems
We need to investigate the potential causes of the decrease in DPF filtration efficiency leading to excessive PM emissions. To address issues such as decreased filtration efficiency and carbon leakage, it is necessary to conduct a thorough investigation into the causes and adopt appropriate solutions.
△ Carbon leakage problem
Carbon leakage may be caused by DPF damage or sensor contamination, and it is necessary to regularly check the DPF and exhaust pipe tail for carbon buildup. Carbon leakage is one of the reasons that requires in-depth exploration. Possible reasons include DPF damage causing carbon leakage, and contamination of the particulate matter sensor with conductive particles inside.
When troubleshooting, you can try disconnecting the DPF backend (if DPF and SCR can be separated), or use an endoscope (if DPF and SCR cannot be separated) to observe the situation at the DPF backend. Meanwhile, checking the carbon buildup at the end of the exhaust pipe is also an effective method. If carbon deposits are found to have significantly turned black, it may indicate that the DPF has burned out and needs to be replaced immediately.
