| Abstract(E) | This study demonstrated the cold start performance of ammonia mono fueled engine system. The system was composed with a commercial four-cylinder spark ignition engine and a developed on-board ammonia reformer by means of autothermal reforming. A TWC (three-way catalyst) and a SCR (Selective Catalytic Reduction) catalyst were also adapted the system for exhaust aftertreatment. The engine achieved a starting operation in 3 seconds while the reformer provided stable hydrogen fraction within several seconds. Zero ammonia emissions and pretty low NOx and N2O emissions were obtained during cold start operation by controlling the air excess ratio of mixture step by step. |
