Advanced alternating piston rotary engine

A method of operating a Rotary Internal-Combustion Engine-Operating System, in which the method is based on Otto Cycle operation wherein a series of explosions is caused within chambers within the rotary internal combustion engine and said method comprises:

• Inside the Internal-Combustion-Cycle Chamber:
• For Otto Cycle operation, at least:
• Causing First and Second symmetrical Sets, of First and Second diametrically symmetrical pistons, each Set facing one another in an alternate position, and rotating freely inside a toroidal Internal-Combustion-Cycle Chamber, around a Drive-shaft perpendicular to their rotational plane, and further, rotationally performing a scissors-like relative movement in between them,
• by the expansion of the explosion of an air/fuel mix, which is tired by an appropriately located Ignition Means and/or a Fuel Injector when it gets in contact with an exactly compressed air/fuel volume, coining from an appropriately located Admission Means, which had previously been rotationally sucked in, on the previous explosion, from an appropriate air/fuel mixing device, or other;
• and
• Finally, by appropriately located Exhaust Means allowing expulsion of spent gases to complete the four phases of the internal-combustion cycle,
• Outside the Internal-Combustion-Cycle Chamber:
• Where there are located The First and Second symmetrical Sets have Central Hubs extending axially outward so as to connect to a Set of First and Second Unidirectional Rotation Transmission Devices, URTDs, arranged in such a way that one of them will necessarily skid, due to angular speed difference, while the other one drives;
• On explosion, a Leading Piston will connect a First URTD) to drive the shaft with the Torque directly generated by the explosion;
• As the drive-shaft is turned by the explosion force, it is also turning two Solar-Gears, of respective Planetary Gear-trains, each Solar-Gear being keyed to the drive-shaft next to the Second URTD;
• Planet-Gears, held together by a Planets'-Carrier, ride on the Solar-Gears backstopped by the Ring-Gear and are, therefore, constantly rotating at a slower speed than the Solar-Gears, because they are smaller, but with a greatly multiplied higher Torque:
• Whereby both Planets' Carriers, each on their respective Planetary Gear-train at each axial end of the drive shaft, are always continuously advancing and multiplying the explosion force and, as they are connected directly to the inner path of the Second URTD, they are always ready to-backstop-and-move-forward any Set of Pistons pushed back by the explosion, since it has a force greater than that of the explosion itself;
• Such that both Sets, of two URTDs each, cooperating with Planetary Gear-trains, or other type of geared-reduction means, will perform as ‘the mechanical brains’ that, on explosion, automatically synchronize the continuously alternating displacement of pistons, Leading/Trailing, generating a continuously scissors-like rotational operation of the engine, respectively opening/closing the rotational angle in between them, every time an explosion takes place at the Ignition Point, to resemble the ‘4-stroke’ internal-combustion-cycle operation.
