本研究係以壓縮空氣為綠色能源,預期建構出一複合壓縮空氣引擎與傳統內燃機引擎作為動力來源的載具,藉由兩者的優勢,來達成具有高效率的綠色長程載具。本研究先分別建立出壓縮空氣引擎與汽油引擎之模擬模型,建構出扭力-轉速-效率的地形圖以及進氣壓力-轉速-扭力圖,並以此去嘗試找出最佳效率的動力分配方式,部分的模擬會經由實驗驗證其準確性和用以預測未來架設完全後的實驗結果,同時也會以實驗數據修正以期會有更好的模擬結果,而藉由實驗數據的網格化則可做為複合系統時電腦判斷查表的依據。 本研究也對複合的細節有所探討,包括不同複合方式的架構,以及複合系統中各模式的切換及各模式運作的原理,像是壓縮空氣增壓汽油引擎、煞車回收與怠速回充等,最後對整個系統之控制邏輯做出說明。
This study constructs a hybrid system by using compressed air engine and internal combustion engine (ICE), in which the compressed air is considered as green energy. By taking advantages of two different kinds of engines, we accomplish a high efficiency and long driving-range vehicle. The research has started with the simulation of the compressed air engine and ICE separately, then I make construction of the map of torque/rotational speed/efficiency diagrams and intake air pressure/torque diagrams. Afterwards, we try to find the best efficiency power split condition. Part of the simulation will be tested by experiments to confirm its practice and the usefulness of prediction before further hardware construction in the future, and I also try to modify the simulation model by comparing with experiment data to make the result better. Thanks for gridding the experiment data, the computer can control the hybrid system by looking up table. This study also discusses about the details of hybrid, including the difference of the hybrid construction methods, the modes which can be switched in the hybrid system and the corresponding principles of those modes. Like supercharging, regenerative braking and idling recharging and so on are included. Finally, we make a statement of the control logic of entire system.
