噴射引擎使用氫氣與汽油燃料對性能之影響分析
Analysis of the Performance in Injection Engine with Hydrogen and Gasoline Fuels
摘要
因使用了大量的石化燃料，近幾年可明顯感受到氣候強烈異常，許多無法預料的大災難隨之而來，不僅嚴重打擊經濟，更威脅到人們的生命財產，為了解決全球暖化及溫室效應，研發出氫氣燃料進而取代石化燃料，期盼更環保的能源，使我們共同生活的地球，能夠永續發展。 本文鑒於溫室效應的嚴重性，應用引擎內燃機運轉模擬套裝軟體GT-Power，模擬目前噴射引擎(Intake Port Injection Engine)中使用石化燃料與氫氣燃料的運轉情況，再應用軟體GT-Post分析討論兩種燃料運轉後所排放的氣體、內燃機的熱傳效率及引擎輸出功率，其中氫引擎運轉時幾乎接近零排放汙染，並且氮氧化物的生成量相較於汽油引擎，少了約1000PPM，但是透過實驗結果發現，在相同的條件下，由於氫氣與汽油的質量密度不同，造成氫氣單位混和體積的熱值比汽油低，致使氫引擎的輸出功率約為汽油引擎的百分之八十，喪失些微的動力換取更節能環保的環境，想必人們也必須在這之中做取捨。

Abnormal climate changes have been noticed increasingly because of various catastrophic phenomena attributable to the intensive use of fossil fuels. Abnormal climate changes have led to the occurrence of numerous unanticipated catastrophes, which severely influence the economy and threaten people’s lives and properties. To address global warming and the greenhouse effect, this study proposes using hydrogen fuel as an alternative to fossil fuels, which can serve as an ecofriendly energy source to protect the earth’s resources and render the earth a sustainable living place. Considering the severity of the greenhouse effect, this study applied GT-Power, a simulation software which can be used to simulate the operation of internal combustion engines, to mimic the performance of common intake port injection engines fueled by fossil fuels and hydrogen. Subsequently, GT-Post software was used to analyze the exhaust gas emission, heat transfer efficiency, and power output of the simulated engines. The results revealed that the operation of the hydrogen-fueled engine emitted nearly zero emission pollutants. Moreover, the hydrogen-fueled engine emitted 1000 ppm less nitrogen oxides than did the gasoline-fueled engine. However, under the same operating condition, the hydrogen-fueled engine produced lower heat values per unit volume than did the gasoline-fueled engine because of the density difference between hydrogen and gasoline. Therefore, the power output of the hydrogen-fueled engine was approximately 80% of that of the gasoline-fueled engine. In this context, people must trade-off between engine power output and maintaining an energy-saving ecofriendly environment.
