DPF frequent regeneration problem

Some car enthusiasts have reported that DPF regeneration occurs frequently, and the reasons for this problem are multifaceted:

1. Whether low ash engine oil is used and whether it meets the requirements of the user manual;

2. Is there a problem with diesel? Diesel problems can directly lead to insufficient combustion, resulting in a large amount of smoke particles blocking the DPF;

3. The oxygen sensor is damaged, leading to an increase in fuel injection and insufficient combustion, resulting in the production of a large number of particles;

4. Frequent short distance driving without heating up the car, if the diesel engine is pressed on the accelerator before the temperature reaches, it will also cause a large amount of smoke particles;

5. DPF burner has a problem and stops working before complete combustion;

6. the sensing components inside the DPF (differential pressure sensor, temperature sensor) are unstable in operation; wait.

In short, there are multiple reasons for the malfunction of DPF regeneration. Although it indicates a DPF malfunction, the root cause of the malfunction may not necessarily be the DPF itself, but may also be caused by other reasons. It depends on the situation and can only be eradicated by targeting the symptoms. DPF is not so delicate, as long as you follow the standards for refueling and maintenance, it is not easy to have problems. Many problems occur with the oil.
