Diesel Particulate Filters (DPFs) are essential components in diesel-powered vehicles, designed to capture and store soot particles from exhaust gases to reduce emissions. Over time, these filters accumulate soot and require cleaning to maintain optimal performance and prevent potential issues. DPF filters when operating correctly should not get blocked or fail but unfortunately, this is a very common and avoidable problem.
Why does a DPF filter block and fail to regenerate properly?
DPFs trap soot particles to prevent them from being released into the atmosphere. As soot accumulates, it increases backpressure on the engine, leading to reduced performance and fuel efficiency. To mitigate this, DPFs undergo a process called regeneration, where accumulated soot is burned off at high temperatures, converting it into less harmful substances. However, certain driving conditions can hinder this process:
- Frequent Short Trips: Regular short-distance driving, especially at low speeds, may not generate sufficient exhaust heat for passive regeneration, leading to soot buildup.
- Extended Idling: Prolonged idling can result in lower exhaust temperatures, preventing effective soot combustion.
- Low-Speed Urban Driving: Consistent low-speed driving in urban areas may not allow the DPF to reach the necessary temperatures for regeneration.
- Incorrect engine oil was used at the time of servicing.
- DPF sensor failure
When regeneration is incomplete or infrequent, soot continues to accumulate, eventually causing blockages that necessitate manual cleaning or, in severe cases, DPF replacement.
Using FTC Decarboniser in your diesel engine will avoid DPF Problems
How to prevent your DPF from Blocking …
To ensure the longevity and efficiency of your DPF:
-
Regular Highway Driving: Incorporate periodic highway driving into your routine. Sustained speeds generate higher exhaust temperatures, facilitating passive regeneration.
-
Monitor Warning Lights: Pay attention to DPF warning indicators on your dashboard. Ignoring these warnings can lead to severe blockages and costly repairs. If your DPF warning light has remained on for an extended period this should not be ignored… Add Add FTC Decarbonizer to the diesel tank ASAP to start the cleaning process.
-
Use Quality Fuel and Additives: Running FTC Decarbonizer Fuel Additive in your diesel will clean your DPF filter and prevent it from relocking with soot.
-
Scheduled Maintenance: Adhere to your vehicle manufacturer’s recommended maintenance schedule, ensuring timely inspections and servicing of the DPF and related components.
By understanding the importance of DPF maintenance and adopting appropriate driving habits, you can enhance your vehicle’s performance, reduce harmful emissions, and avoid unnecessary repair costs.
