複合氣動系統能量匯流管理之研究
Study of Energy Merger Management of Hybrid Pneumatic Power System
摘要
複合氣動系統特色能使內燃機維持在最佳運轉區域下運轉，並透過能量匯流管裝置將內燃機所排放之廢氣能量與壓縮空氣混合回收利用，驅動氣動馬達產生動力，有效提升內燃機熱效率與減少廢氣排放。系統測試平台以市面上現有液氣壓元件所匹配而成，在各零組件之間各裝設感測器擷取類比訊號，經由資料蒐集器(NI-USB-6229)蒐集彙整後，傳送至電腦運算、記錄並顯示於人機介面，有效分析各元件能量使用狀況。 本研究主要以實驗探討能量匯流過程，壓縮空氣的壓力太大會使內燃機廢氣能量無法順利匯流，導致嚴重影響氣動馬達輸出功率，利用控制能量匯流管管徑改變能量匯流管截面積產生文氏管效應，使內燃機廢氣能量匯流過程順暢，有效的將內燃機廢能回收提升系統效率。由本文結果可得知在不同壓縮空氣壓力與氣動馬達負載狀態下最佳能量匯流管管徑調整控制量，進而建立複合氣動系統能量匯流管理策略。

One characteristic of hybrid pneumatic power system (HPPS) is that it enables internal combustion engines (ICE) to operate at its sweet spot of maximum efficiency. Through energy merger device, HPPS can recycle both the exhaust-gas energy of an internal combustion engine and compress air to activate the air motor. HPPS can increase thermal efficiency of ICE and helps reduce exhaust emissions. Through the data collection device (NI-USB-6229), the data was collected and then conveyed to the computer operations, record and show on Human Machine Interface. This research is mainly to investigate the process of energy merging by experiment. The compressed air energy will influence the ICE exhaust gas energy in the merger process. It will deeply affect the air motor output power. Modulating the diameter of energy merger pipe improves backflow phenomenon in tube and promotes efficiency more. The experimental result shows the compressed air energy and air motor at different load conditions to adjust the best energy merger control the state of tube diameter, and establish the HPPS management strategy.
