Influence of Compression Ratio on Combustion and Emission Characteristics of Hydrogen Internal Combustion Engines Under Different Excess Air Coefficients

Hydrogen internal combustion engines (H<sub>2</sub>-ICEs) are a promising solution for decarbonizing heavy-duty transportation. This study investigates the effects of compression ratio (CR: 9, 11, 13) and excess air ratio (λ: 1–5) on the performance, emissions, and combustion characteris...
