NOx/e-fuels interactions in combustion engines

The current energy transition is witnessing the rising interest towards e-fuels, i.e. energy carriers able to store the excess energy obtained from renewable sources like wind or sun, then releasing it “on demand”. For this reason, a comprehensive description of their chemistry needs to be achieved. Specifically, their interaction with Nitrogen Oxides (NO_x) is of the utmost importance in internal combustion engines, due to their presence because of the Exhaust Gas Recirculation. The objective of this thesis is obtaining a fundamental understanding of the chemical interactions between e-fuels, and NO_x, and integrating such knowledge within a detailed kinetic mechanism, necessary to ensure a predictive degree to the CFD simulations.
