Cleaning fluid tested in the laboratory, 100% safe for filters and the environment Controlled sludge utilization from the cleaning process
we always give the best price
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.
UK emissions standards for cars effectively required fitment of a DPF in the exhaust of diesel cars in 2009 when the ‘Euro 5′ standard came into force. Many cars before this time already had one fitted in anticipation of this requirement but its generally accepted that very few diesel cars manufactured before 2006 had a diesel particulate filter fitted.
If you are in any doubt, the unit should be visible if you have under the vehicle. They are normally located to the front of the exhaust system. If you’re not mechanically minded then it may be beneficial to take along a mechanic if you are looking to buy a car but are keen to avoid having a DPF.
The DPF warning light displayed on the dash board indicates that the filter is not working correctly or is in need of maintenance / regeneration. Sensors within the device or the exhaust monitor the back pressure and temperature of the system to ensure its working correctly. When the readings from this sensors are outside a preprogrammed limit this will trigger the warning. Once activated, the light should trigger a regeneration of the filter or could indicate that the device is faulty and in need of replacement or repair.
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. DPF Regen Conditions Engine at normal operating temperature At least 40MPH At least 2500RPM Fingers crossed!
