The lifespan of DPF (diesel particulate filter) is mainly affected by the usage environment and maintenance conditions. ‌

Lifespan range and influencing factors

Theoretical lifespan: According to relevant national standards, the design lifespan of DPF can reach 200000 kilometers. If calculated based on the annual mileage of 10000-20000 kilometers for household cars, the service life of DPF can reach more than 10 years, basically covering the normal service life of a vehicle.

Actual lifespan: In actual use, the lifespan of DPF will be affected by various factors:

Driving environment: When driving on congested urban roads, prolonged low-speed and low load operation of the engine can increase the frequency of DPF regeneration and accelerate its aging.

Fuel quality: Using substandard and inferior fuel can lead to an increase in particulate matter, accelerate DPF blockage, and affect its efficiency.

Maintenance frequency: Regular maintenance can ensure that the engine and emission system are in good condition. Neglecting maintenance can increase the burden on the DPF and affect its lifespan.

Methods to extend lifespan

To extend the service life of DPF, car owners can take the following measures:

Regular maintenance of vehicles: Strictly follow the requirements of the vehicle manual, regularly replace key components such as oil and air filters to ensure that the engine is in the best working condition and reduce the generation of particulate matter.

Use fuel and oil that meet the standards: Choose high-quality fuel and oil from regular gas stations to ensure that the cleanliness and grade of the fuel meet the requirements of the vehicle.

Avoid frequent regeneration: By driving at high speeds or using original engine oil, enhance fuel emission rates, avoid impurity accumulation, and extend the service life of DPF.
