The present invention provides an improved rotor mechanism to improve the mechanism of the intermeshing displacement rotor and valve rotor. The main feature is that the displacement rotor and the valve rotor provide the operation curve from the carryover period to intake period, which includes a pair of convex curves with different radius merging smoothly with each other, thereby providing a smooth transference of the intake, exhaust, and carryover, etc. and avoiding noise and vibration during the working process. Moreover, the displacement rotor and the valve rotor provide the operation curve from the starting of exhaust to the period of ending, which is defined by an arcuated surface thereby providing a rotor mechanism with great diplacement transference and high compression ratio.
