碩士 === 國立臺北科技大學 === 車輛工程系所 === 97 === 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.
