Diiselpartiklipuhastus, often referred to as DPF cleaning, is a process designed to remove accumulated soot and particulate matter from a diesel particulate filter. This filter is a crucial component in modern diesel engines, designed to reduce harmful emissions by trapping exhaust particles. Over time, these particles build up, leading to a clogged filter.

A clogged DPF can significantly impede engine performance, increase fuel consumption, and potentially cause severe engine damage. DPF cleaning aims to restore the filter's functionality and prevent these issues.

There are several methods for DPF cleaning. Passive regeneration occurs automatically when the engine is running under conditions that generate sufficient exhaust heat, such as sustained highway driving. Active regeneration is initiated by the engine control unit when it detects a certain level of soot accumulation. This involves injecting extra fuel into the exhaust to raise the temperature and burn off the soot.

For heavily clogged filters or when passive and active regeneration are insufficient, manual cleaning methods are employed. These can include professional cleaning services that use specialized fluids or ultrasonic baths to dislodge stubborn deposits. In some cases, a DPF may need to be replaced if it is damaged or cannot be effectively cleaned. Regular maintenance and proper driving habits can help prolong the life of a DPF and reduce the need for frequent cleaning.
