Abstract: An engine structure having a conjugate cam assembly is provided and includes a piston which can be used to push or pulled by the conjugate cam assembly mounted on a camshaft through a connection rod, a roller rocker and two rollers. The conjugate cam assembly has two cams with cam profiles and relative arrangement angle which can be varied according to actual operational desire, so as to vary the ratio of intake/exhaust strokes and the ratio of compression/power strokes. Thus, the combustion efficiency and the exhaustion efficiency can be enhanced. When the camshaft finishes four strokes of an operational cycle, the camshaft only rotates one circle (i.e. 360 degree), so that the rotation speed of the camshaft can be lowered.
