摘要: 
本研究的主要目的是探討四缸四行程汽油引擎進氣系統設計對引擎進氣量的影響,並以一維非穩態可壓縮流模式來進行進氣系統設計,進而探討各項設計參數對引擎進氣性能的影響。研究的目標引擎為三陽工業公司發展1.4L汽油引擎。整個研究的執行可分成兩部份,分別為:(1). 建立目標引擎進氣系統的數值模型,並以實驗數值調整一維可壓縮流計算進氣模式,並根據引擎之實際量測結果作系統模式的參數修正,作為後續發展數值引擎進氣系統的重要參考依據。(2). 針對進氣系統進行設計分析,以找出不同轉速下較適當的進氣系統設計參數。改變的設計參數包括進排氣閥門正時、閥門最大揚程、進氣歧管管長與管徑。
經過本研究的模擬計算,若將進排氣閥門正時、最大揚程與進氣歧管尺寸等條件互相搭配調整,則引擎在各轉速下整體的進氣效率都可以提高,其中在1200rpm時,可提高10.24%,在3200rpm時,可提高7%,在5600rpm時,可提高12.68%。

The main purpose of this study was to investigate the engine intake design effects on the intake air mass for the four-cylinder four-stroke gasoline engine by one dimensional unsteady compressible flow mode. Execution of the entire study can be divided into two parts, the first is to create the numerical model for the engine intake system, and then revise the numerical model according to the measured results. The second is to vary the intake system design parameters to determine the best intake system design at different engine speeds. The design parameters include intake and exhaust valve timing, valve maximum lift, intake manifold length and diameter. After the study, it was found that if the parameters could be collocated well, the volumetric efficiency can be improved in the full range of engine speed. At 1200rpm, volumetric efficiency can be raised by 10.24%. At 3200rpm, the increment is 7%, and at 5600rpm, 12.68% of increase can be reached.
