This invention describes a mechanism containing two coaxial rotators, embedded on a driveshaft, (1a, 1b) that spin alternately with two velocities. Each rotator has at least two vanes (2) and during the rotators' spin chambers of variable capacities form between the vanes. When the vanes touch together the velocities of the rotators change (2). Rotation speed changes from V1 to V2 and vice-versa are enabled by gearshifts consisting of two-speed ratchets (3) interlocked with rotators' shafts (1a, 1b) that transmit force from and to steering ratchets (4). At a constant velocity of the steering ratchet (4) after its every 180 rotation the angular velocity of the two-speed ratchet (3) and rotator change. The correct functioning of the whole mechanism is provided by engagement of the steering ratchet, transporting force from and to the two-speed ratchet (3), with the coaxial steering ratchet (4) transporting force from the rotator (1b).

An internal combustion engine utilizes the four-cycle process. Gas working chambers are formed using portions of a toroid, two opposing pistons, and seals at the inner gap. A cycle occur over 360 degrees of the toroid with gas ports appropriately placed. One Power Vane (PV) and one Reaction Vane (RV) connect to a central shaft with one piston assembly attached to each end of each vane. The PV produces driving torque on a central shaft through an Overrunning Clutch System (OCS). At specific angles and for controlled durations the PV and RV are slowed, stopped, held to the housing, and then accelerated and coupled to the shaft. Vane movement is controlled by gears, cam ramps, and pin mechanisms operated via multiple, independent but time-coordinated systems. The power vane has no controlled acceleration as combustion forces couple this vane to the shaft via the OCS.
