Diesel Particulate Filter regeneration

DPF regeneration

The Diesel Particulate Filter (DPF) is regenerated by a process of combustion of the soot particles accumulated inside the filter. There are two types of DPF regeneration: passive and active.

    1. Passive regeneration : It occurs when engine exhaust temperatures are high, typically during highway driving or intensive engine use. High temperatures burn off soot particles and clean the filter.
    2. Active regeneration : It is triggered by the engine management system and can occur while driving or when the vehicle is stationary. During active regeneration, the engine management system raises the exhaust temperature by injecting fuel into the engine to burn off soot particles in the filter. This process can take from 10 to 30 minutes.

It is important to note that DPF regeneration is an automatic process and does not require driver intervention. However, if the FAP is clogged or damaged, it may need to be replaced or professionally cleaned to restore normal exhaust system operation.

You have a problem with your vehicle, such as loss of power, an engine warning light on, exhaust fumes, or you’ve failed your roadworthiness test for pollution, contact us.

Before replacing expensive parts, don’t hesitate to contact our FAP Cleaner technicians who can accurately diagnose your problems and suggest alternative solutions before replacing the parts.
