The quest for clean, efficient engine technologies is imperative in reducing transportation’s environmental impact. Hydrogen, as a zero-emission fuel, offers significant potential internal combustion engines but faces challenges such optimizing performance and longevity. Water injection proposed solution, yet its effects on require thorough investigation. This study bridges the knowledge gap by examining various water ratios (WIRs) their impact performance, focusing balance between power output We identified existence of an optimum WIR (e.g., 10% this study), which provides peak with minimal adverse health. Computational simulations single-cylinder revealed how WIRs influence in-cylinder temperature, pressure, IMEP, emphasizing nuanced benefits injection. Additionally, our analysis turbulence, through TKE dissipation rate, deepens understanding fuel efficiency hydrogen engines. research valuable guidance operations paves way advanced systems engines, marking step towards cleaner technology.

<div class="section abstract"><div class="htmlview paragraph">Hydrogen internal combustion engines (H<sub>2</sub>-ICE) do not emit any fuel-borne carbon emission species. Nitrogen oxides are the remaining raw species at significant levels. However, exhaust aftertreatment system is exposed to a different matrix, including unburned hydrogen. This raises question of role hydrogen emissions for system. Extensive synthetic gas bench (SGB) test campaigns address in several production catalyst components. Starting with selective catalytic reduction (SCR) systems, systematic variation concentration shows rather small effects on NO<sub>X</sub> performance. A change selectivity results increased secondary N<sub>2</sub>O copper-zeolite system, whereas vanadium-based SCR unaffected. both types highly sensitive NO<sub>2</sub>/NO<sub>X</sub> ratio emission. Therefore, an upstream oxidation remains important low temperature Investigations catalysts varying platinum loadings show performance higher content. effect attributed accelerated heating centers due exothermic reaction. In parallel however, increase during light-off, speaking against post-oxidation-based strategy. The strongest sensitivity found lambda sensors. Fast diffusion through zirconia distorts signal towards rich mixtures. Overall, emphasize hydrogen, especially respect emissions, requesting H<sub>2</sub>-ICE-specific operating strategies achieve zero-impact tailpipe emissions.</div></div>
