現今我們的生活中與動力交通工具密不可分，例如汽車或摩托車。燃油引擎製造出的廢氣排放是非常驚人，嚴重影響空氣的品質。本研究討論汽油內燃機在不同的引擎轉速與空燃比(AFR)參數中，分析自然進氣與吸入汽化水分子後對廢氣排放的改善。液態水溶液汽化過程中，汽化水分子經由化水器蒸發作用下，經由空氣導入內燃機(ICE)燃燒室中燃燒。從不同引擎轉速實驗結果中得到驗證，在5000 rpm可以得到動力性能的提升，馬力效率增加8%，扭力效率增加6%；AFR14 在稀薄燃料燃燒下降低 NOx、HC 和 CO 廢氣排放的結果詳細顯示：（1）3500 rpm 時 NOx 的改善值降低了約 63 ppm，（2） 4500 rpm時 CO 氣體效率降低了約 20%， (3) HC 在 5000 rpm 以上最多減少約 2.5 ppm。本研究提供減少廢氣的方法與增加動力性能，實驗結果已得到驗證，我們的研究將進一步實踐友善環境的願景。

Nowadays, our lives are inseparable from power vehicles, such as cars or motorcycles. The exhaust emission produced by the fuel engine is very alarming, which seriously affects the quality of the air. This study discusses how gasoline internal combustion engines can improve exhaust emissions after natural intake and inhalation of vaporized water molecules in different engine speeds and the air-fuel ratio (AFR) parameters. During the vaporization of the liquid aqueous solutions, the vaporized water molecules are introduced into the combustion chamber of the internal combustion engine (ICE) through the air and burned through the vaporization of the water vaporizer. It is proved from the results of different engine speed experiments that the power performance can be improved at 5000 rpm, the horsepower efficiency is increased by 8%, the torque efficiency is increased by 6%. The results for AFR14 reduces NOx, HC, and CO exhaust emissions under lean fuel combustion are shown in detail: (1) the improvement value of NOx at 3500 rpm is reduced by about 63 ppm； (2) CO gas efficiency is reduced by about 20% at 4500 rpm, and (3) the HC is reduced by about 2.5 ppm at most above 5000 rpm. This research provides methods to reduce exhaust gas. The experimental results have been verified. Our research will further implement the vision of a friendly environment.
