  • Toyota DPF: understanding your diesel particulate filter ...

    2014-10-20 · Why do modern diesel engines need a particulate filter? European legislation places strict exhaust emissions targets on all vehicle manufacturers. From September 2009, the Euro 5 legislative standard came into effect, part of which required all diesel cars registered from that point on to be equipped with a diesel particulate filter, or DPF.

  • Diesel particulate filter problems: How to solve them ...

    2021-7-26 · To counter this series of diesel particulate filter problems, FTC treated diesel results in a reduction in both the total number of soot particles, and the total soot mass produced. Secondly, it forces all carbon in combustion and exhaust spaces, including any soot trapped in the DPF, to combust at temperatures as low as 350C to 400C.

  • Darkside Developments - Diesel Particulate Filter (DPF)

    A Diesel Particulate Filter (DPF or FAP for short) is a filter found in the downpipe section of the exhaust and is specifically designed to reduce the amount of Diesel Particulate Matter (Soot/Ash) passing through. The objective of this filter is to create cleaner more eco friendly exhaust gases being released into the atmosphere.
