Response strategies for post-processing blockages

In the face of DPF blockage caused by engine oil burning ash, conventional solutions include replacing the DPF or manually disassembling and cleaning it. However, prevention is always better than treatment. In the daily maintenance of vehicles, we only need to pay a little attention to significantly reduce or even avoid the occurrence of post-treatment blockages.

The key to solving the problem of post-processing blockage is to reduce the ash content in the DPF. Since the ash content mainly comes from the combustion of engine oil, we can start with engine oil. Choosing low ash engine oil can effectively reduce carbon soot in exhaust gas, thereby reducing the risk of DPF blockage. In addition, low ash engine oil produces less ash during combustion, which means less non combustible ash will enter the DPF, thereby reducing the likelihood of DPF problems.

The issue of DPF is increasingly attracting attention from both new and old car owners. Although DPF has a certain regenerative ability, over long-term use, ash substances will gradually accumulate and cause blockage. Therefore, regular cleaning is particularly important to ensure the continuous and effective operation of DPF.
