Combustion Analysis of Ammonia Fueled High Compression Ratio SI Engine with Glow Plug and Sub-Chamber

Ammonia is a kind of energy carrier hydrogen, and its use as engine fuel has been studied. However, it requires overcoming shortcomings low combustion speed. We focus that the laminar velocity gasoline mixture with an excess air ratio at 2.0 same ammonia. The ammonia was simulated by using experiments under lean-burn conditions experimental sub-chamber glow plug. Through experiments, data such optimal ignition angle NOx emissions during lean are obtained. Based on above data, authors did co-combustion experiment gasoline/ammonia/air. Under 1.1, 1.2, 1.3, maximum content 33%NH3, could be operated less than 10% variation in IMEP.
