Advanced combustion and aftertreatment technologies

  • Advanced aftertreatment

    The overall aim is to develop a gasoline particulate filter (GPF) to allow vehicles to comply with upcoming Euro 6 RDE limits with particle number emissions measured to a 10nm size threshold.

    The aim of this study was to assess Lagrangian-Eulerian CFD models for the simulation of Gasoline sprays under non-flashing and flashing conditions. Both conditions can be well reproduced, also maintaining the grid resolution quite high (0.5 mm) in order to be suitable for combustion simulations in a real engine geometry.

  • Fuel-film evaporation and combustion

    The aim is to develop optical diagnostics to investigate the impact of evaporating fuel films in combustion as a source of polyaromatic hydrocarbons (possible particle precursors) (PAH) and soot.

    High-speed colour combustion-imaging visualizes the spray and fuel films, illuminated by a green LED, the flame front by chemiluminescence, and soot by natural incandescence. To read more on the results of Laser Induced Fluouresence (LIF) based fuel-film imaging.
