<div class="section abstract"><div class="htmlview paragraph">Pre-chamber (PC) technology has demonstrated its capability to achieve clean and stable combustion in internal engines (ICEs) under lean conditions. This study evaluates the effectiveness of PC direct injection (DI) hydrogen (H<sub>2</sub>)-ICEs compared conventional spark ignition (SI) operation using high-fidelity computational fluid dynamics simulations across a range load Various loads were attained by systematically adjusting intake pressure injected H<sub>2</sub> mass. The primary hypothesis posits that highly turbulent jets facilitate rapid mixing ultra-lean mixtures. comparative analysis revealed DI fueling both SI modes did not perfectly homogeneous mixtures, particularly high conditions, although slightly enhanced mixture uniformity. Combustion behavior exhibited non-monotonic trend, with outperforming at low loads, while superior performance medium despite elevated heat transfer losses. Additionally, maintained concentrations OH radicals, promoting faster indicating potential for auto-ignition suppression. In conclusion, specific tasks optimizing systems identified, providing clear directions future research.</div></div>
