Advanced combustion and Research

Establish the solid basis for model-supported design and control based on an in-depth understanding and cause and effect relationships of particle formation of the in-cylinder processes. Read more

Aim is to visualize fuel films on the piston surface and soot precursors within the combustion chamber to understand the cause and effect relationship between fuel films and particle formation. Read more

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. Read more

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.
