A valve mechanism of an engine comprises a camshaft, a driven wheel (20), a rocker arm (30), and an air valve (40). The air valve (40) and the driven wheel (20) are connected to the rocker arm (30). A cam (10) of the camshaft is combined with the driven wheel (20) and can drive the driven wheel (20) so as to open or close the air valve (40). The rim of the driven wheel (20) is provided with a protrusion (21). The protrusion (21) is disposed on the driven wheel (20), so that the opening degree of the air valve can be suddenly increased, which helps to discharge residual gas out of a combustion chamber, the air in the combustion chamber is thus made fresher, and the effect of optimizing the scavenging is achieved.
