英文摘要：

This paper presents the structure of a novel two-stroke micro free swing piston engine, （MFSPE） and creates the kinematics equations of four-connecting-rod mechanism. The calculation of movement simulation for MFSPE is conducted with ADAMS, the performance curves of MFSPE model has been obtained. The analysis result shows that the structure design for the mechanism of MFPSE is reasonable, and it is applicable for the steady operation of the system.
