摘要

本研究目的在以電池之電動車輛技術為基礎，著重於泛用引擎的性能及製造低成本，發展具有區域性特色及市場潛力之小型複合動力機車。經濟性、輕量化及動力輸出特性，是泛用引擎的優勢所在，具有改善車輛排氣污染及節省能源消耗之目的。
本研究整合複合動力系統搭載於選定之目標車上進行工程驗證，以應用電動馬達低速性能佳，配合泛用引擎高轉速高扭力的輸出特性，落實技術可行性及實用性。在現有實驗樣品中，為了降低更多製造成本，除了使用49cc低價格泛用引擎，且採用傳動系統為固定減速比系統，電動馬達系統以500W/36V輪圈馬達搭配。整體構想：低轉速時，由電動馬達動力輸出；高轉速時，由引擎動力輸出；重負荷時，雙動力系統輸出。
本研究以實驗車實際地面進行測試，再以測試結果進行分析與討論。分析結果顯示，泛用引擎是可應用於複合動力機車上。但本研究之引擎動力經固定減速比系統輸出，將無法改變引擎輸出扭力，使得動力輸出或銜接有不平順，且引擎未處於高效率運轉區域而有耗油情況。

The purpose of this research is to develop a hybrid electric motorcycle (HEM) with utility engine. That is based on electronic vehicle technology with battery, and focus on the performance of the utility engine and low cost of manufacture. The utility engine has the advantages of low cost, light weight, and high power density, which reduce the exhaust pollutions and energy consumption of the vehicle.
This research combines a utility engine and a motor in a target motorcycle to establish a hybrid electric motorcycle. The utility engine has high power at high speed and the electric motor has good performance at low speed. In order to achieve low cost and light weight, an existing 49cc utility engine and a 500W/36V wheel motor are used. The concept of this HEM is to drive the vehicle with motor at low speed and run the engine at high speed.
This hybrid electric motorcycle is tested with practical running, and then the test results are analyzed. The results show that the application of utility engine on hybrid electric motorcycle is feasible. However, the transmission system is limited in one gear ratio, so the power output is not smooth and the fuel economy is not good.
