Claim:
A relaying piston valve-less electromagnetically controlled internal combustion engine comprising: a fully enclosed toroidal cylinder cavity with uniformly smooth bore, connected with only one inlet port and one outlet port to a gaseous medium; three semi-toroidal pistons within said cylinder cavity; said semi-toroidal pistons slidingly enclosing and moving along said gaseous medium within said cylinder cavity; winding means on said cylinder cavity to selectively impart electromagnetic forces on each of said semi-toroidal pistons for electromagnetically selected and forced successive movement, braking and stationary-making of each of said semi-toroidal pistons; at least two windings, placed in the angular distance between said inlet and outlet ports, to successively hold electromagnetically at least one of said semi-toroidal pistons at a time; said gaseous medium enters from said inlet port into said cylinder cavity where said semi-toroidal pistons with said electromagnetically selected and forced successive movement of each of said semi-toroidal pistons, one at a time, slidingly effecting intake and compression of said gaseous medium to produce a combustion either by auto-ignition or by initiation from an outside source in the form of either an electrical discharge through said medium or an injection of hydrogen/hydrocarbons into said gaseous medium; the volumetric expansion of said gaseous medium from the kinetic energy released during said combustion effecting the post-combustion angular mechanical movement of each of said semi-toroidal pistons with a sensor sensing said combustion and electromagnetically releasing each of said pistons from a stationary status, one at a time; each of said semi-toroidal pistons in said stationary status prior to said combustion having also immovably effected, one at a time, said compression of said gaseous medium, while each of said semi-toroidal pistons, one at a time, slidingly effecting said intake and compression of said gaseous medium to produce a combustion, going into said stationary status undergoing an electromagnetic status reversal with said sensor sensing said combustion; said combustion taking place successively in a manner that the next said combustion takes place subsequent to said gaseous medium having volumetrically expanded fully inside said cylinder cavity after the first said combustion and reaching said outlet port; and following said combustion, after a short delay, the one of said pistons, slidingly having effected said intake and compression of said gaseous medium which produced said combustion, moving to occupy the space vacated by the one of said semi-toroidal pistons in said post-combustion angular mechanical movement; and each one of said semi-toroidal pistons successively moving after each said combustion, one by one, in the direction of said angular movement, to always keep blocked the shorter of the two angular distances between said radially located inlet and outlet ports inside said cylinder cavity.
