中文摘要 | 本文係利用純柴油及含水量5, 10, 15%的油水乳化液,應用在一四汽缸,四行程 的柴油引擎上,做(1)固定節流閥,(2)固定轉速,及(3)定轉速但改變噴油時間下 的測試,量測引擎在各條件下的性能、效率,同時並分析排氣中污染物的變化。並藉引擎實 驗所得之各項數據,配合對乳化液液滴燃燒行為的瞭解,由此分析及討論油水乳化液在引擎 中所可能發生的一些燃燒現象,以進一步瞭解油水乳化液應用於柴油引擎上所遭遇的問題。 綜合實驗結果顯示,油水乳化液的使用,在所有的實驗狀況下,微粒子與 NO �X的生成或排 放,會造成明顯的減少。在實驗範圍內,微粒子的減少量可達 30 %,而 NO �X的減少量更 可達 75 %。至於油水乳化液對引擎性能的影響,則在不同的操作條件下,或有所改進或有 負面的效果,但變化並不很大。以整體而言,油水乳化液在柴油引擎上確有其可行性。 觀察冷卻水熱損失、排氣溫度的變化,可知燃料燃燒的行為確會因噴油時間的改變而有所變 化。但由於噴油時間的改變,對引擎的效率,並無太大的影響。而其對微粒子的產生有減少 的功用,但卻使 NO �X的生成增加;在實驗範圍內,微粒子的減少與 NO �X的增加,分別可 達 20 %與 70 %。 |
英文摘要 | The report here used diesel and its 5, 10, 15% water-diesel emulsions in a four-stroke, four-cylinder diesel engine, and then performed the test under (1) constant throttle, (2) constant rotational speed, and (3) constant rotational speed with different injection timing of fuel. The test results which included the engine performances and the pollutants formed within the exhaust. We then analyzed and discussed those results base on the fundamental understanding of the burning charateristics of emulsified fuels, and tried to get better view of the emulsified fuels reacted in a diesel engine. The experimental results showed that in all test conditions, the usuage of the emulsified fuels remarkably reduced the exhausted particulate and NO �X. The reduction of particulate and NO �X could up to 30 and 75%, respectively. As for the engine performance, there was a positive or negative affect under different test conditions, but the change was not perfounded. From the overall point of view, the usuage of water-oil emulsion in a diesel engine is feasible. By investigation the variation of the cooling water heat loss and the exhausted gas temperature, we can conclude that the burning characteristics of fuel were altered by the changing of the injection timing of fuel. There was not much impact on engine performance, the exhausted particulate was further reduced, but NO �X formation was increased. Within the test ranges, the reduction of particulate and the increasing of NO �X were up to 20 and 70%, respectively. |
