為因應全球暖化、能源短缺造成高價能源時代來臨，節能減碳儼然成為全球共識，機車為目前台灣地區最普遍的個人交通工具，在台灣人的生活中佔有極重大的地位。但是機車所排放的一氧化碳、碳氫化合物與氮氧化物，皆是造成空氣污染的主要活動污染源。本論文主要使用排氣量150c.c之汽油引擎機車(Scooter)、電動馬達、控制器及機構研發一台並聯式混合動力機車。使用底盤動力計來進行混合動力系統性能測試。而本系統主要使用低功率馬達來改善汽油引擎機車低速域效能不佳的問題。本研究分別對於引擎系統、馬達系統、動力轉換系統等進行動力與性能測試。由實驗結果可知此並聯式油電混合機車主要可分為性能與油耗效益兩大特色。油電混合動力系統於0-7秒利用電動馬達負責起步驅動車子，7秒過後以燃油引擎動力驅動車子，節流閥開度為12.5%，測試時間為0-30秒，行駛距離為100公尺做靜止起步、加速、停止之循環測試，並耐久測試，均可維持6%以上之油耗降低率，動力銜接平順，此項優勢著重於低加速性之交通壅塞路況。

To face the coming of high-price energy era caused by global warming and energy shortage, energy conservation and carbon reduction are just like the consensus of all countries all over the world. In Taiwan, motorcycle is currently the most common personal transportation. Therefore, motorcycle plays an extremely important role in Taiwanese daily lives. Unfortunately, according to the statistics made in the past years, the carbon monoxide, hydrocarbon and nitrogen oxide emitted by motorcycles are the main active pollutants causing air pollution. This thesis primarily researched and developed (R&D) the parallel hybrid system using 150c.c motorcycle (scooter), electric motor, controller, and mechanism. The chassis dynamometer was used to test the performance of the hybrid scooter. This system use lower power motor to improve the performance of the gasoline engine in low speed domain. The engine system, motor system, and power transformation system was tested to explore its power and performance. The experimental results reveal that this parallel hybrid motorcycle had two major characteristics in performance and fuel consumption. The hybrid system started the motorcycle with the electric motor in the first 0-7 seconds, and then drove the motorcycle with a fuel engine at a throttle valve opening of 12.5%. The test time was set to be 0-30 seconds. The driving distance was 100 meters. Through the cycle test and endure test from standing start, acceleration to stop, we found a reduction of at least 6% of the fuel consumption could be attained. The driving was smooth. This advantage focused on low acceleration in traffic congestion condition.
