The 3 main culprits of DPF blockage (with real repair cases attached)
1. Dust particles exceeding the standard
A logistics company's fleet statistics show that the DPF blockage rate of vehicles driving on the G60 Shanghai Kunming Expressway is as high as 28%, mainly due to the dust concentration of 15mg/m ³ (the national standard limit of 10mg/m ³) on this section. It is recommended to activate the DPF manual dust cleaning function in advance when passing through heavily polluted roads.
2. Poor fuel quality
In 2023, a third-party inspection report showed that the DPF blockage cycle of vehicles using blended diesel was shortened to 4000 kilometers (the standard should be 12000 kilometers). It is recommended to choose a gas station with the "National VI B" logo for each refueling, which can increase the fuel qualification rate to 92%.
3. Long term short distance driving of vehicles
According to data from 4S stores of certain Japanese brands, vehicles with an average daily mileage of less than 30 kilometers have a probability of DPF blockage 3.2 times higher than those with an average daily mileage of 80 kilometers. Because DPF needs to reach above 500 ℃ to function properly, it is impossible to reach the cleaning temperature for short distance driving.
