The Potential of Hydrogen Internal Combustion Engines in a Future Mobility Scenario

Focus is pointed on the highly favorable physical properties of hydrogen (H₂) with regard to its combustion characteristics in internal combustion engines. Thereby it will be shown in how far the performance of next generation hydrogen engines can be improved by implementing a direct fuel injection system instead of the conventional port injection approach. Results from numerical as well as from experimental investigations will be used to clearly give a vision of the overall future potential of hydrogen for combustion engines in comparison to fuel cell systems.
