摘要

本研究將重組器置於排氣管內，利用引擎排氣廢熱對其加溫，配合燃料及空氣供應控制系統進行實驗。重組燃料使用乙醇，經重組器重組產出之富氫氣體，導入引擎作為輔助燃料，並分別於引擎測試及實車穩態及暫態測試。引擎測試方面，分別為引擎轉速(5000、6000)rpm，油門開度(1/3、2/3、3/3)；實車測試方面分為穩態：車速(40、50、60km/h)、暫態測試：起步加速及續走加速。測試項目包括廢氣排放、燃料消耗及溫度等特性，以了解導入富氫氣體之後，燃料消耗、污染排放及行車特性。
在引擎測試方面，引擎轉速於5000rpm，H2+CO莫爾流率為0.14-0.2(mol/min)，排污均能獲得改善；實車部分，在車速40km/h的情況下，添加能量百分比為25.7%、H2+CO流率0.11mol/min、空氣過剩率比為1.06的時候，能量改善率達23%、排汙方面均可獲得改善；車速50km/h時，能量百分比20%、H2+CO流率0.11及0.16mol/min時，能量消耗及排汙，均能獲得正面的改善；於車速60km/h時，各H2+CO流率，空氣過剩比1附近，排污方面均能獲得改善。
整體而言添加富氫氣體之後，選擇適當的重組器操作參數，在穩態行車狀態可以在排汙方面獲得改善。

In this study, the hydrogen was produced by a pipe reformer, and the hydrogen-rich gas was introduced into the engine. Ethanol and air were introduced into the reformer to generate hydrogen-rich gas. Experiments were carried out on the engine dynamometer and chassis dynamometer. The control parameters included engine speeds (5000, 6000 rpm), throttle openings (1/3, 2/3, 3/3), steady and transient running conditions were conducted, and the driving performance, fuel consumption and exhaust emissions of the motorcycle were measured.
In engine tests, emissions can be improved at engine speed of 5000 rpm and H2+CO molar rate of 0.14-0.2 mol/min. As for the results of the vehicle tests, at vehicle speed of 40km/h, energy percentage of 25.7, H2+CO molar rate of 0.11mol/min, excess air ratio of 1.06, energy consumption of engine could have 23% improvement and emissions could also be improved. At 50km/h, energy percentage of 20 and H2+CO molar rate of 0.11 and 0.16 mol/min, energy and emissions could be improved simultaneously. At vehicle speed of 60km/h, adding hydrogen-rich gas, excess air ratio near 1, emissions could be improved. As a whole, adding hydrogen-rich gas to engine, reduction of emission was significant at the tested vehicle speeds.
