Abstract: A valve transmission mechanism (1) of an engine, for installation on a cylinder head (9) of the engine, and mainly comprising a drive shaft (10), a cam assembly (20), a driven assembly (30) and a valve assembly (40). The drive shaft (10) may be pivotally connected to the cylinder head (9) so as to link the cam assembly (20), link the driven assembly (30) by means of the cam assembly (20), and then link the valve assembly (40) by means of the driven assembly (30). The driven assembly (30) is restricted to linearly reciprocate between a first position (P1) and a second position (P2). When at the first position (P1), an intake valve (41) or an exhaust valve (42) of the valve assembly (40) may be linked to close opposite intake ports (911) or exhaust ports (921) on the cylinder head (9). When at the second position (P2), the intake valve (41) or the exhaust valve (42) is linked to open the opposite intake ports (911) or exhaust ports (921). Since the valve transmission mechanism (1) directly pulls to close or pushes to open the intake valve (41) or the exhaust valve (42), time delay and excessive power loss may be effectively avoided, so that the air intake and exhaust have better results, thereby improving the power output efficiency of the engine.
