Abstract
An improved two cycle engine is disclosed which includes a subchamber which is in communication with the exhaust port with a cylindrical valve rotatably disposed therebetween. A reed valve unit is turnably supported in the inlet port to open and close the latter. The cylindrical valve is operatively connected to the reed valve unit by way of a linkage mechanism. Either of the cylindrical valve and the reed valve unit is actuated by a servomotor and the other one is actuated by the linkage mechanism. The servomotor is controlled with the aid of a control circuit so as to allow the engine to be operated at a predetermined number of revolutions.
