What is the reason for the frequent stationary self-cleaning of the Fengjun 5?
1 Answers
Excessive self-cleaning frequency is caused by an excessive accumulation of incompletely burned carbon soot in the DPF, which can lead to clogging. Here is additional information: 1. Differential pressure sensor: When the DPF's differential pressure sensor detects excessive exhaust pressure, it triggers the combustion of particulate matter in the DPF for cleaning. The ECU will then continuously perform post-injection for self-cleaning. 2. Certified oil: Use ACEA C3-certified oil. During automatic self-cleaning, ensure the engine speed remains above 2000 RPM. While driving, try to maintain the engine speed in the green zone to optimize combustion efficiency. Additionally, consider installing an LU.
