What is a DPF?
A diesel particulate filter (DPF) is a device which sits in the exhaust system, it “captures” soot / diesel particulate and other nasty particles so they are not released into atmosphere. A diesel particulate filter can remove upwards of 85% of the particles from the exhaust, reducing harmful emissions.
The DPF physically captures the soot and ash particles in a net or mesh like structure within the filter.
There are two different types of DPF regeneration that are commonly used. These are active and passive. Which ever your car uses you’ll still have to meet some strict conditions in order for the regeneration to start. It’s usually a combination of engine temperature, speed and RPM. A rule of thumb is that the engine needs to have reached normal operating temperature, you’re travelling at more than 40MPH and the RPM (revs) of your engine is at least 2500 RPM. Depending on how blocked or effective your regeneration will determine how long it needs to be performed.
- Engine at normal operating temperature
- At least 40MPH
- At least 2500RPM
- Fingers crossed!
