摘要

氫引擎燃燒後，排放水與少量氮氧化物的特性，是解決車輛排放溫室氣體的替代方法之一。熱力學分析，較計算流體力學更快速的了解引擎效能。本研究係利用熱力學零維度模型，分析氫、汽油兩種引擎的性能差異。氫燃料具備燃燒迅速、熱值高的特性，此一特性導致熱損失較汽油引擎顯著。但是也因為燃燒快速的特點，反而造成氫引擎在高轉速區的熱效率表現，明顯高於汽油引擎的熱效率。

Hydrogen engines have little exhaust emissions, except water vapor and nitrogen-oxide. Hydrogen engine may be the vehicle alternative power source of lower green house gases. Thermodynamics analysis is more convenient than computer aid fluid dynamic in engine simulation. In this research, zero dimension thermodynamics model was be used to analysis the difference between gasoline and hydrogen. Hydrogen has high burning velocity and high heating value. Those properties result to high heating loss in SI engine. But, also raise the thermo efficiency in high engine speed.
