Based on the Fluent-CFD software, a three-dimensional dynamic grid numerical model was established to simulate the combustion process of a micro internal combustion swing engine (MICSE) with a free-swinging arm. One-step reaction mechanism of n-butane oxidation was employed for numerically calculating the flow and combustion processes in the combustion chamber. The effects of three inner diameters of combustion chamber on the output performance of MICSE were compared. The results showed that increasing the inner diameter can reduce the fuel residue at the bottom of the chamber, accelerate combustion, increase the peak pressure and shorten the occurrence time of peak pressure, which is beneficial to improve the output power, power density and thermal efficiency of MICSE.
