充氣就能跑 氣動機車零汙染

朱芳瑤／台北報導 2008.09.04 中國時報

中央大學三日發表「中大綠能一號氣動機車」，以氣動馬達（Air Motor）及高壓氣桶取代傳統機車的油箱和引擎，免汽油、免電能，利用空氣驅動，真正零汙染。這項應用為全球首例，研究成果將刊登於《應用能源》期刊（「Applied Energy」），已申請專利。

這款空氣概念車由中央機械系教授黃衍任與博士生沈毓達研發，只要高壓空氣就可驅動機車馬達。沈毓達從廢車廠拖回一輛機車，換上高壓空氣鋼瓶、過濾器、控制閥及最關鍵的氣動馬達，再調整鋼瓶容量及穩定度。

黃衍任解釋氣動機車的原理，先由氣壓鋼瓶產生高壓氣體，空氣經由過濾器去除水分，再由控制閥進入氣動馬達，以調整機車速度。氣動馬達以空氣驅動後，將產生旋轉動力，帶動機車齒輪與鏈條而前進。

黃衍任強調，氣動機車堪稱無汙染交通工具，僅鋼瓶填充高壓空氣時，充氣機需使用電力運轉。目前填充速率為一分鐘一四○至三二○公升，不用一分鐘便可完成。

這台氣動機車使用工業最小號的十公升氣鋼瓶，壓力為每平方公分一百公斤，充氣一次僅能跑一至二公里，時速最高三十公里。進入實用階段前，還要解決行駛中空氣驅動噪音、充氣機造價十幾萬起跳及鋼瓶重達十五公斤等問題。

Currently in Taiwan, there are more than 13 million motorcycles, mostly driven by internal combustion engines, and the pollutants, carbon monoxide (CO) and unburnt hydrocarbons (HC), generated by motorcycle are responsible for more than 10% of the air pollutants released to the atmosphere. The studies show that the internal combustion engines of motorcycles may generate up to two times more pollutants than those of automobiles. In order to improve the air pollution condition and eliminate the pollutants exhausting, this paper presents a new idea of using compressed air as the power sources for motorcycles. Instead of an internal combustion engine, this motorcycle is equipped with an air motor, which transforms the energy of the compressed air into mechanical motion energy. A prototype is built with a fuzzy logic speed controller and tested on the real road. The experiment data shows that the speed error is within 1 km/h and the efficiency is above 70% for this system when the speed is over 20 km/h.
