What does DPF overload mean?
2 Answers
DPF overload means that the DPF particulate filter in the exhaust pipe is severely clogged and requires cleaning and regeneration. The relevant introduction about the particulate filter is as follows: 1. Function: The full English name of DPF is "Diesel-Particulate-Filter", which literally translates to "Diesel Particulate Filter", also known as the Diesel Particulate Filter Regeneration Device. It is a device that can reduce particulate matter (PM) emissions in the exhaust. 2. Definition of DPF regeneration: During the operation of the filter, particles accumulate inside it. When a certain level is reached, it can lead to a decline in engine performance and fuel economy, among other aspects. It is necessary to promptly remove the accumulated particles to ensure the DPF continues to function properly, which is referred to as DPF regeneration.
I often help friends with car repairs, and DPF overload is quite common. Simply put, it's when the Diesel Particulate Filter gets clogged—this device is installed in diesel vehicles to capture soot particles from the exhaust, and when too much accumulates, it overloads. The reasons? Many cases involve frequent short-distance driving, like daily city commutes stuck in traffic for just a few kilometers, where the engine doesn't get hot enough to burn off those particles. It could also be due to using low-quality diesel or faulty sensors failing to trigger automatic regeneration. Once overloaded, the dashboard warning light comes on, power noticeably drops, and driving feels like dragging with the handbrake on. Over time, this can damage the engine, leading to expensive repairs. Prevention? I recommend at least one weekly highway trip lasting over half an hour to allow system regeneration. If issues arise, take it to a professional shop early for cleaning or part replacement—don't cut corners to save money. Regular maintenance is key to avoiding hefty repair bills.
