Abstract(E) | Hydrogen (H2) internal combustion engines (ICEs) are emerging as an attractive option for high power, high duty cycle vehicles and are expected to play a strong role in achieving rapid decarbonization of hard-to-electrify markets. However, H2 readily pre-ignites which limits achievable power and a portion of H2 can slip through the ICE un-combusted, negatively impacting thermal efficiency. Pre-chamber combustors can extend the lean limit in H2 ICEs and increase combustion stability, reducing pre-ignition and eliminating H2 slip. In this study, the ability of a pre-chamber combustor to reduce pre-ignition and H2 slip is demonstrated, and the mechanisms are investigated. |
