A direct-drive rotary engine having a rotor housing, the rotor housing having an interior wall structure which defines the open interior of the engine compartment, including an air intake region, a compression region, a combustion region, an expansion region and an exhaust region therein, in which is rotatably disposed a cylindrical rotor assembly coaxially fixed to an engine shaft. The rotor receives a plurality of slidable and retractable sliding walls in a radial arrangement, respectively at positions substantially equal spaced on circumference of said rotor. The sliding walls are pressures biased to the surrounding inner wall structure of the rotor housing during the rotation of the rotor. The reciprocating movements of the sliding walls define the working chambers of the engine as the rotor rotates, dividing the rotor housing into plurality of sweeping airtight chambers, so that the Otto cycle are carried out once for each sliding wall during a complete revolution of the rotor. That is to say, it is apparent that in this invention the sequence of the intake, compression, combustion and exhaust engine cycles is executed repeatedly by the number of the sliding walls on one rotor.
