Impact of biofuels on DPF regeneration; Partikelfilter-Regeneration bei Biokraftstoffen

The Institute for Combustion Engines (VKA) of RWTH Aachen University carried out detailed investigations to explore the potential of future biofuel candidates for optimised combustion systems. The chemical structure of these new fuels may impact the thermal decomposition chemistry and consequently in-cylinder particulate formation conditions. This work fundamentally focusses the influence of fuel properties on particulate matter reactivity and, thereby, the regeneration behaviour of a diesel particulate filter (DPF). (orig.)
