The engine operation show in figures 21, 22, 23 and 24. In each cylinder is performed a complete cycle by each complete rotation of the rotor. Meanwhile, each satellite makes two complete rotations on its own axis. Each piston makes four strokes or phases to complete a cycle. In each phase the rotor tour 90 degrees, and then, each crank turns 180 degrees in the same direction and on its own axis.

Figure 21 shows intake stroke in cylinder (A) and power stroke in cylinder (B). The cylinder (A) is discovered during the entire stroke by the intake distribution port, while is closed by the stator the cylinder (B). In this phase the pistons rotates with smaller speed that the rotor, and make a negative stroke, being provoked in the cylinder (A) the draw (input) of fresh air charge and being produced in the cylinder (B) the expansion of the gases inflamed by the spark plug. The piston of this cylinder pushes in this phase to the crankshaft, and this push transmits it to its satellite and to the rotor as rotary torque. The gases are admitted mixed previously with fuel by a carburetor installed to the entry of the intake.

Figure 22 shows compression stroke in cylinder (A) and exhaust stroke in cylinder (B). The cylinder (A) is closed during all the phase by the stator, while the exhaust distribution port discovers the cylinder (B) during all the phase. In this phase each piston make a positive stroke. Therefore rotates with greater speed that the rotor, being provoked in the cylinder (A) the compression of the gases and in the cylinder (B) the exhaust of the gases burnt. At the end of this phase, the interior of the cylinder (A) enters contact with the spark plug, which inflames the combustible mixture.

Figure 23 shows power stroke in cylinder (A) and intake stroke in cylinder (B). The intake distribution port discovers the cylinder (B) during all the phase, while the stator close the cylinder (A). In this phase the pistons make a negative stroke, rotating with smaller speed that the rotor, being provoked in the cylinder (B) the charge of fresh air-fuel mixture and being produced in the cylinder (A) the expansion of the inflamed gases. In this phase, the piston of this cylinder pushes the crankshaft inwards, and this push is transmits by the satellite to the rotor as rotary torque.

Figure 24 shows exhaust stroke in cylinder (A) and compression stroke in cylinder (B). The cylinder (B) is closed during all the phase by the stator, while the cylinder (A) is discovered during the entire stroke by the exhaust distribution port. In this phase each piston make a positive stroke, therefore rotates with greater speed that the rotor, being provoked in the cylinder (B) the compression of the gases and in the cylinder (A) the exhaust of the gases burnt. When the rotor completes a rotation, in each cylinder has been effect the four-operation stroke, beginning then in each one a new cycle.

For the implementation of the engine is applied electrical contact on the ignition device. After is made to turn the rotor, until are produced the first explosions. Then, the engine must turn in a way autonomous, in so much the carburettor supply air-fuel mixture.
