In order to use novel, regenerative fuels (eFuels, e.g. hydrogen) in engines, their effects on the physical processes must be understood. Port fuel injection (PFI) can be used to produce a lean homogeneous mixture, and then the effects of adding a direct injection can be subsequently investigated.
This work is concerned with characterizing the injectors currently in use in terms of injected mass. Different atmospheric pressures and temperatures have to be considered. After designing the experimental setup, the measurements are to be carried out and evaluated.
