Sustainable mobility requires storage technologies that allow energy for mobility to be stored, transported and made available worldwide at marketable prices. In view of the enormous global demand and limited resources as well as the high energy density required in mobile applications, this demand can only be partially met by electrochemical storage and electrical drives. New sustainable fuels are required and are currently being investigated in numerous research projects or have entered series production as an E-gas (methane) in a first pilot application. In particular, so-called electro-fuels, in which regeneratively generated electricity is stored at high energy density, enable a gradual improvement of the CO2 balance up to CO2-neutral mobility. In addition to greenhouse gases, however, pollutant emissions must also be reduced to an absolute minimum in internal combustion engine drive systems, for which the joint development of fuel and combustion processes offers new development opportunities. The initial mixing of fuel and air, which is currently carried out by highly developed direct injection systems, is a particularly critical process, as it influences all other sub-processes in the engine's operating chain. Up to now, it can only be mapped and optimized within narrow limits with the aid of simulations, since the spray generated in high-pressure injection processes is so dense in its starting condition at the outlet of the injection nozzle that investigations of the primary break-up of the injection jet are very demanding and were only possible to a limited extent. The research project uses state-of-the-art measuring methods for the fundamental investigation of the mixture formation of e-fuels in order to enable the optimised use of new energy sources.
