Reactivity Controlled Compression Ignition (RCCI) stands out as a promising combustion method for the next wave of internal engines, offering cleaner and more efficient operation, particularly in heavy-duty engines. A key approach within this strategy involves pairing diesel high reactivity fuel with natural gas (NG) low counterpart. Further optimization can be achieved by introducing hydrogen to replace portions NG, thereby enhancing quality while reducing greenhouse emissions. For accurate numerical simulation engines employing strategy, specialized chemical kinetics reaction mechanism tailored becomes essential. To facilitate computationally 3-D Computational Fluid Dynamics (CFD) simulations, has been reduced include 60 species 372 reactions, N-heptane acting surrogate. This compact is optimized align experimental ignition delay time (IDT) data N-heptane. The accuracy mechanism's predictions IDT laminar burning velocity (LBV) validated using available data. Furthermore, CFD quasi-dimensional multi-zone engine simulations are performed new validate operating parameters against
