摘要

在考慮環境保護及能源需求的因素下，生質酒精可適用於汽車引擎，可做為汽車之替代燃料。本研究係以TOYOYA 4AFE引擎進行替代燃料試驗，以不同比例含氧油料MTBE及酒精摻配汽油中，探討油品對引擎性能、油耗及排氣污染之影響。
由試驗結果可知：
基礎油料摻配含氧油料後，其辛烷值會增加，但是熱值卻隨之降低，因此，含氧油料之最大燃燒壓力會比基礎油低；由CO的廢氣分析結果可知，CO排放量會隨油門開度增加而降低，而在高轉速2500rpm時，含氧燃料HC的排放量均會較低，含氧燃料的NO排放量均比基礎油低。

In considering environment and energy requirement, bio-alcohol is an attractive alternative fuel for automobile. The effects of alcohol blending with MTBE on the TOYOYA 4AFE gasoline engine combustion characteristics were investigated. The engine performances, fuel consumptions and exhaust emissions were also studied.
The test results showed that:
MTBE and alcohol could increase fuel octane number and decrease heating value. Combustion pressures for oxygenated fuels were lower than base fuel. CO emissions were decreased with increasing throttle open angle. HC emissions were low for oxygenated fuel at 2500rpm. A lower NO emissions were measured for oxygenated fuels.
