摘要

本論文主要對道路廢能儲存與發電系統之油壓傳動部份進行技術開發與效率量測以及道路廢能發電裝置之內部構造進行探討，此道路廢能儲存與發電系統係由『宇春綠能源科技股份有限公司』與本CCT實驗室共同開發的技術並已擁有多國的專利。本研究先針對此系統之先期四缸模組進行空氣儲能與油壓傳動之效率測定，由結果發現空氣之儲能效率在腔體壓力達到300kPa時，效率約為15%，而油壓傳動之效率為48.33%。另外，針對油壓傳動部份利用位能之方式進行能量的儲存開發油壓儲能裝置，能夠將車流量的不穩定輸入源，調整為穩定的輸出源，穩定的帶動後段之發電系統，位能儲能裝置之實驗規格為高度一公尺，單次車輛理論可使其上升7.8cm，重物重量為1960kg，目前之最高油壓轉換效率為重物重量1960kg時約34.25%。本研究並針對油壓傳動系統作整體性的探討，觀察各種形式之活塞環在作動過程中之洩漏問題，在採用PE材質之U型油環時，可有效解決洩漏問題。還有，測試用之受壓塊原使用鋼鐵結構，考慮整體系統之成本問題，改採用水泥缸結構以替代之，其兩者之油壓傳動效率分別為：鋼鐵結構43.36%，水泥結構49.15%。本系統之道路廢能儲存與發電系統將建立於下高架橋之下坡路段與減速路段，使用車重約1000kg之小型車進行一般柏油路面與壓過本受壓塊裝置之滾動摩擦比較，分別為14.11kg與37.06kg，此值可進一步對油耗進行分析。本道路廢能儲存與發電系統安裝在路面上，於減速路段時可使駕駛者減少踩煞車的機會，將煞車所需的能量收回進行發電。

This study is focused on hydraulic transmission part or developing the roadway system of waste energy storage and electric generation. The main works are technical development, efficiency measurement, and design of internal structure. The roadway system of waste energy storage and electric generation is developed by Yen-Chun green energy technology incorporated company and our CCT Laboratory, which has been patented in many countries. In this work, a four cylinder module is first measured the working efficiency with air storage and hydraulic transmission. The results show that efficiency of the air storage is ca. 15% while the chamber pressure is 300kPa and efficiency of hydraulic transmission is ca. 48.33%. Moreover, applying the potential energy storage can collect and transfer the instable vehicles energy to the stable output energy for stable electric generation. The potential energy storage is with height of 1 $m$ and weight of 1960kg. It is theoretically risen 7.8cm while one car runs over. The reached efficiency of hydraulic conversion is ca. 34.25% while the weight on the potential energy storage is 1960kg. This work had also studied oil leakage for the motion of piston and found the solution by using the U-type oring of PE material. Furthermore, the steel pressure piece is changed to use the cement for reducing the cost. The working efficiency of the pressure piece for the steel structure is 43.36% and for the cement structure is 49.15%. This roadway system of waste energy storage and electric generation will be installed at the downhill section of elevated bridge and decelerating section. The rolling friction of a car with ca. 1000kg is 14.11kg for running over asphalt road and is 37.06kg for running over this pressure piece. As a whole, this roadway system of waste energy storage and electric generation can reduce the braking times of car and capture the waste energy for electric generation.
