Summary
Probably the greatest challenge for future mobility is the development of an environmentally friendly propulsion system without losing the advantages of today’s engine concepts. The hydrogen-fuelled combustion engine in a direct-injection configuration shows great potential for achieving this goal. The high number of degrees of freedom of direct-injection concepts leads to the need for deeper investigation into the basic in-cylinder processes, which is preferably done by multidimensional, non-intrusive measurement techniques. For according investigations a transparent one-cylinder research engine and a measurement system for Laser-Induced-Fluorescence (LIF) has been installed at the Institute for Internal Combustion Engines and Thermodynamics at TU Graz. In this paper the use of this optical measuring method on a hydrogen engine is described together with its particular application on the mixture formation process and the combustion. Selected results are presented to show the gained insights as well as further potentials in the mixture-formation and the combustion process.
