An improved overhead camshaft driven by a toothed belt and a poking plate is common to engines. Or, a cam (57t) is additionally arranged at the end part of a guide rod of a valve element of a one-way valve beside a combustion chamber of a cylinder block (44) to conduct driving, and is used as a valve, and the cam and a belt gear I (57c) are arranged coaxially. Or, the poking plate (57b), having an effect of a lever, is additionally arranged at the end part of a rod of a valve (57p), and is driven by the cam (57t). The cam shaft comprises the toothed belt, and the toothed belt is connected with a belt gear of a crankshaft. The teeth of the belt gear are shaped like multi stars. A plurality of penetrating holes are formed in the toothed belt, so that the possibility of deflection is low. An active driving one-way valve engine is not closed occasionally. The inner wall of the combustion chamber of the engine takes the shape of a parabola. The ignition point of the spark plug is arranged at the focal point of the
