Background & Policy context

The main advantage of Hybrid Diesel Cars (HDC) is to strongly reduce the fuel consumption and, consequently, the emission of CO2 as well as the vehicular dependence on hydrocarbons.  The ambitious target fuel consumption of HDC is 3 L for 100 km for a medium motorisation passenger vehicle (1.6 L). However, HDC will still require a complex catalytic post-treatment in order to achieve future European legislations (EURO 6 in 2014 and EURO 7 in 2018-2020) in terms of emissions of NOx, unburned hydrocarbons, CO and particulate matter. The actual solution for removing soot particulates is the Diesel Particulate Filter (DPF) which is a porous ceramic structure.


The main objective of PIREP2 is to develop a new generation of self-regenerating Diesel Particulate Filters (self-DPF) from the knowledge on filtering electrochemical catalysts acquired during the PIREP1 project (ADEME program, 2007-2010), managed by IRCELYON with the support of PSA.

PIREP2 is an industrial research project which aims to:

  • Develop and optimize self-DPFs, based on ionic conducting ceramics, able to continuously burn soot particulates from 250°C without fuel overconsumption and without the use of noble metals.
  • Understand the mechanism for soot particulates activation by ionic conducting ceramics.
  • Analyse the gaseous and particulate emissions of HDC as well as the impact of self-DPF on nucleation processes (production of ultrafine particulates).
