Special Issue Information

Dear Colleagues,

Mobility is the heart of our human society in the third millennium. This Special Issue of Energies is focused on research in the area of serving mobility with new, green sustainable energy. The increasing role of cognitive tools in data acquisition, decision making, and research and development is opening new avenues. Reviews and research innovations on (but not limited to) the following topics are welcome:

  • Traditional fuel reformulation;
  • Advanced and renewable fuel production and application;
  • Innovative combustion methods;
  • Hydrogen production, storage, and use in internal combustion engines or fuel cells;
  • Hybrid drivetrains and vehicles;
  • Newest electricity-related developments in storage and utilization;
  • On-board vehicle management.

Prof. Dr. Zöldy Máté
Guest Editor

This study explores the performance and emissions characteristics of a dual-fuel internal combustion engine operating on a blend of hydrogen and gasoline. This research began with a baseline simulation of a conventional gasoline engine, which was subsequently validated through experimental testing on an AVL testbed. The simulation results closely matched the testbed data, confirming the accuracy of the model, with deviations within 5%. Building on this validated model, a hydrogen–gasoline dual-fuel engine simulation was developed. The predictive simulation revealed an approximately 5% increase in overall engine efficiency at the optimal operating point, primarily due to hydrogen’s combustion properties. Additionally, the injected gasoline mass and CO2 emissions were reduced by around 30% across the RPM range. However, the introduction of hydrogen also resulted in a slight reduction (~10%) in torque, attributed to the lower volumetric efficiency caused by hydrogen displacing intake air. While CO emissions were significantly reduced, NOx emissions nearly doubled due to the higher combustion temperatures associated with hydrogen. This research demonstrates the potential of hydrogen–gasoline dual-fuel systems in reducing carbon emissions, while highlighting the need for further optimization to balance performance with environmental impact.
