甲丙醇燃料的共沸效應對柴油引擎影響之研究

The Study of The Effect Azeotropic effect of Methanol-Porpanol Fuel on FT Diesel Engines

摘要


廣泛使用於大眾交通物流運輸工具的柴油引擎,其排放廢氣中的黑煙、氮氧化物、碳氫化合物和懸浮粒狀汙染物等有毒物質造成空氣汙染,嚴重影響人類健康。故本研究使用FT(Fischer-Tropsch process)合成柴油,並將甲醇及異丙醇混合添加於FT合成柴油中進行實驗,探討蒸餾溫度較低的甲醇及蒸餾溫度較高的異丙醇混合對柴油引擎的性能影響。實驗結果證明,甲醇與異丙醇添加入FT合成柴油中可改善柴油引擎廢氣排放問題,尤其是引擎廢氣中smoke及HC的含量均有減少之效果。

並列摘要


The diesel engines are widely used in public transport vehicles. Its emissions of smoke, NOX, HC and PM cause air pollution, and affect human health seriously. In this study, we used Fischer-Tropsch diesel fuels and mixed methanol and isopropyl alcohol with the Fischer-Tropsch diesel fuels and filled into vehicular diesel engine tank. The experiment results show that adding methanol and isopropanol in Fischer-Tropsch diesel fuels can help to improve the problem of diesel engine exhaust emissions. In particular, it effectively reduces the engine exhaust smoke and HC concentration.
