High compression ratio, high power density homogeneous charge compression ignition engines using hydrogen and carbon monoxide to enhance auto-ignition resistance

摘要

High compression ratio, homogeneous charge compression ignition engines. In one aspect the engine is dual mode utilizing spark ignition at high load levels including the addition of hydrogen or a hydrogen/carbon monoxide mixture. In another aspect, the engine operates on a high cetane fuel with the addition of hydrogen or a hydrogen/carbon monoxide mixture at low-to-mid-load levels.
