The concept and principle of setting an ignition point of a sparking plug on the focal point of a combustion chamber can be popularized to various engines and instrument equipment. A single-cylinder gasoline engine provided with a crankcase and synchronous belt transmission valve mechanism comprises an active-driving one-way valve type engine body, and occasional poor actuation is avoided. One end of a valve spring is ground flat, so that edge folding matched with valve clamping is facilitated; the other end of the valve spring is a free end, so that high-speed free swinging of a valve element is facilitated; an arc-shaped chamfer with a function curve is arranged on the front portion of a front valve seat and can be conveniently matched with a sealing ring on the periphery of a function curve of the valve element; a key hole of a valve clamping disc can be arranged in a valve clamping groove in a sleeved mode in the axial direction and then mounted in the valve clamping groove in the radial direction; and th
