本研究提出以一小一大單缸氣動引擎進行串聯的Split-Cycle氣動引擎，可以讓輸入氣動引擎的高壓氣體進行兩次膨脹，達到將高壓氣體之壓力完全利用的目標，以提升氣動引擎的輸出功率與效率。　
模擬部分以商用軟體MATLAB建立Split-Cycle氣動引擎模型，再以建立好的數值分析模擬獲得在不同進排氣時序、不同引擎壓縮比下運轉過程中缸內壓力變化與輸出功率、扭力、效率對於轉速的關係，並分析此雙缸氣動引擎的輸出性能與特性，並且透過實驗進行驗證。
此外在實驗當中也發現兩缸連接管會影響Split-Cycle氣動引擎的表現，因此透過實驗進行探討不同粗細之連接管所造成的影響。最後以光陽MONGOOSE 90沙灘車之構造為基礎，搭配本研究的實驗數據進行單缸氣動引擎與Split-Cycle氣動引擎實車性能評估，探討兩種引擎特性之差異。

This thesis proposed a novel Split-Cycle air engine that was composed by one smaller and one larger cylinders. This two-cylinder air engine has two expansion strokes in the larger cylinder to make full use of high pressure air. Therefore, the power and efficiency of air engine were raised.
Simulation in this research used MATLAB to establish Split-Cycle air engine model and use the model to analyze the cylinder pressure, power, torque, efficiency in various turning speed, valve timing and compression ratio. Then the characteristics of Split-Cycle air engine obtained from simulation were verified with experiments.
In addition, the experiment found that the high pressure tube between two cylinders influenced the power and torque outputs of Split-Cycle air engine, so the effect of diameter of high pressure tubes on the performance of the engine was investigated. Finally, this research used the experimental data to conduct emulation of single cylinder air engine and Split-Cycle air engine based on the configuration of KYMCO MONGOOSE 90, then pros and cons of both engines were compared.
