。 A two-stroke cycle comprising an exhaust timing control valve disposed in an exhaust port opened on the inner surface of the cylinder to be opened and closed by a piston slidably fitted in the cylinder, and an irregular combustion suppressing means for suppressing irregular combustion. In the engine, the asymmetric combustion suppressing means operates in the drive means connected to the exhaust timing control valve to operate the exhaust timing control valve in response to the drive means operating in the direction of decreasing the engine output. The control means to which the suppressing means is connected and controlling the operation of the driving means is configured to operate the driving means in a direction in which engine output is reduced in response to detection of an operating region where irregular combustion is likely to occur or detection of occurrence of irregular combustion. A two-stroke engine characterized by:
