摘要： Apparatus, methods and systems reside in the decomposition of ammonia into a hydrogen-containing product mixture. An ammonia-rich gaseous mixture containing ammonia and oxygen enters a conduit, within which combustion and decomposition of the mixture is initiated, thereby liberating hydrogen. A mixture of products, resulting from the reactions, is expelled from the outlet of the conduit, the mixture including non-combusted hydrogen gas, which may then be used for other purposes. The incoming reactants, including ammonia and oxygen, are heat exchanged with the outgoing product mixture containing non-combusted hydrogen gas.

摘要： Described herein are various embodiments of an apparatus, system and method for operating an oxygen-enriched ammonia-fueled spark ignition engine. According to one illustrative embodiment, a method for operating an oxygen-enriched ammonia-fueled spark ignition engine includes fueling the engine with a mixture of ammonia and auxiliary oxygen within a first engine load range between zero and an engine load associated with a target combustion condition selected from the group consisting of rough limit, MBT knock limit, and any of various conditions between the rough limit and MBT knock limit. Within the first engine load range, the amounts of ammonia and auxiliary oxygen consumed per cycle increase as the load increases. The method further includes fueling the engine on a mixture of ammonia, auxiliary oxygen, and air within a second engine load range between the engine loads associated with the selected target combustion condition and the maximum engine load.

摘要： Described herein are various embodiments of an apparatus, system and method for operating a dual fueled spark ignition engine. For example, according to one illustrative embodiment, a method for operating a dual fueled spark ignition engine includes fueling the engine solely with a combustion promoter within a first engine load range between zero and an engine load associated with a target combustion condition selected from the group consisting of rough limit, knock limit, and any of various conditions between the rough limit and knock limit. Within the first engine load range, the amount of combustion promoter fueling the engine increases as the load increases. The method further includes fueling the engine on a mixture of ammonia and the combustion promoter within a second engine load range between the engine load associated with the selected target combustion condition and the engine load associated with a maximum operating pressure of the engine. Within the second engine load range, the amount of ammonia fueling the engine increases and the amount of combustion promoter fueling the engine remains substantially constant as the load increases.
