BACKGROUND OF THE INVENTION 
     In mechanical energy production through internal combustion motors, several different engines have been developed featured by carrying out 4 basic functions or strokes: admission, compression, explosion and exhaust. This type of engine was the invention of August Otto and has been subsequently the subject of several changes. Its basic principles remaining unchanged; these gave rise to engines having 4-valves per piston, 2 sparkplugs per piston, engines with cylinders in line or in V, engines carrying out the 4 functions or strokes in two turns of the piston crankshaft, the so-called 2-stroke engine; also there are engines with pistons divided around a crankshaft, mostly used in aviation, the toric engine as well as others. The Wankel engine at one thee was considered the potential definite substitute of the traditional Otto piston engine, but due to higher fuel consumption, in relation to the traditional engine, forced the idea to be abandoned. There is also the engine that due to over-compression explodes its mixture, such as Diesel engine, and there exist other power plants that have not been proven a challenge to the Otto engine. At present, auto manufacturers and others, are looking for other options to substitute internal combustion engines, for example, electric engines. 
     SUMMARY OF THE INVENTION 
     An object of the invention is to use 4 basic strokes: admission, compression, explosion and exhaust, to manufacture a new internal combustion motor plant, characterized by its ability to produce energy within rectangular chambers inside a circular device, whereby the 4 strokes are carried out using rectangular piston blades pivoting at one end and transmitting power through the other end of the piston blades to the pinions via the connecting rods and the crankshafts. These moving pinions, that according to their movement push the rotor, actuate through a gear a fixed pinion or a fixed interior toothed-ring, allowing it to begin a new cycle once a cycle has ended. 
     In one embodiment of the engine having 4-piston blades, it has the ability to repeat the cycle of admission, compression, and explosion and exhaust cycle once each revolution or turn of the engine, and in the embodiment having 8-piston blades, twice each revolution or turn of the engine. That is, either the pinions traveling across an internal fixed toothed-ring or encircling a fixed pinion with the same relation, 2:1 for the 4-piston blade engine, 4:1 for the 8-piston blade engine and 6:1 for 12-piston blade engine embodiment. 
     The present invention further relies on a lubrication system where oil comes into through the central portion of the engine by means of a mechanical seal with holes and slots and is evacuated through seals along the periphery of the rotor. 
     The present invention further includes an air-cooling system, located in the sides or the rotor, provided with turbines allowing for air to pass from one side of the rotor to the other by means of chambers in the fixed portion of the stator. The lubrication system also helps in the cooling due to the hot oil evacuated from the engine passes through a radiator. The engine seals or gaskets are similar to those of the Wankel engine, these seals lowering friction both in the chambers as in the rotor. 
     The present invention, additionally, is provided with a reinforcing system or additional aid to piston blade displacement by explosion through polarization of the piston blades with positive or negative magnetic charges which are repel or repulsed with its stator, when piston blades are nearer the stator with the same type of positive or negative magnetic charge. The charge of the electromagnet of the stator is increased at the moment that it passes a few degrees from its maximum position through the load yielded by the alternator or dynamo, which is synchronized and distributed by means of timers, electronic panels, thus further lowering fuel consumption.

     DETAILED DESCRIPTION OF THE INVENTION 
     FIG. 1 shows a rotary internal combustion engine  100 , where curved rectangular piston blades  200  realize the four strokes: admission  104 , compression  106 , explosion  108  and exhaust  110 . The piston blades are supported at a proximal end  112  while the distal end  114  is transported due to explosion  108  pushing a connecting rod  116  which moves a crankshaft  118  making the pinion  120  rotate, which when supported on the fixed pinion  122  rotates twice per rotation, pushing and making the rotor spin through the bearings  124  which are embedded between rotor lids (not shown), between the crankshaft  118  and the pinion  120  of each piston blade  200 ; the explosion  108  being carried out by  8  sparkplugs  126  arranged in two rows of four sparkplugs  126 . Four curved divided seals (not shown), located in each side over the periphery of the rotor  128  are supported and produce a tight seal with the stator  130 . 
     FIG. 2 shows a curved rectangular piston blade  200  with a cavity  202  at its base, in proportion to the compression necessary, ranging from 1:1 to 1:15. Also a system of seals is shown, including edge seals  204 , central linear seal  206  and circular seal  208  around the proximal end  112 . In this circular seal  208  and plug seal  210  there are small boxes  212  wherein the ends of edge seals  204  and central linear seals  206  enter, thus gaining a perfect seal for the fin  200  and its chamber is completely sealed in any position. 
     FIG. 3, along with references to FIG. 1, show how lubrication and cooling takes place. Lubrication takes place by oil  302  going into the engine through external ducts  304 . The engine has a drilled seal with a ring-shaped slot  306  allowing for oil  302  to enter into the inside of the rotor  128  through 4 drilled pipes  308  distributed one per chamber that permanently sprays oil  303  in those areas requiring lubrication and various internal ducts  310  lead pinion lubrication oil to the piston blades  200  Slots  314  located along the length of peripheral seals  312  allow for the evacuation of oil  302 , which pass across slots and ducts (not shown) with the aid of an oil pump. To enhance cooling, hot oil  302  passes through a radiator  318 . The cooling system operates through the air taken in, and sent by turbine  320  from one side of the rotor  128  to the other side, through stator cavernous body  322  where it is received at the other end by a second turbine  324 , which suctions and expels air allowing the suctioning of air, both for admission and for conditioning of the air. The rotor  128  is supported by dual-stoke rolls  326 , which function either horizontally or vertically. These cooling and lubrication systems operate both in the engine shown in FIG.  1  and FIG.  4 . 
     FIG. 4 shows a rotary internal combustion engine  400  having eight curved and rectangular piston blades  200 , wherein one revolution of the rotor  128  in the stator  130 , requires four revolutions of the pinions  120  inside the fixed internally-toothed ring  402  or the fixed pinion  122 , thereby requiring four turns per revolution and 2 piston blade  200  cycles per turn, that is, twice admission  104 , compression  106 , explosion  108 , exhaust  110 . This engine differs from the engine of four chambers shown in FIG. 1, in that the engine of FIG. 1 has four chambers, four connecting rods  116 , four crankshafts  118  and four pinions  120 . Also, related to the four chamber engine, the pinions  120  are supported either in the fixed internally-toothed ring  402  or in the fixed pinion  122 . The rotary internal combustion engine  400  lowers rotor  128  velocity relative to that in FIG. 1, but with increased power. 
     FIG. 5 shows a rotary internal combustion engine  400  in a front view having eight curved and rectangular piston blades  200 . The engines major feature is the way pinions  120  are geared in the fixed internally-toothed ring  402  with a 4:1 ratio. It is outfitted with mechanical seals  404  keeping oil  302  from coming out when entering through mechanical seals  404  and passes from pinions  120  to piston blades  200  by means of internal ducts  310  distributing and expelling oil  303  through the same systems displayed in FIG.  3 . 
     FIG. 6 shows a portion of the rotor surface  128 where one can see how peripheral seals  312  are arranged with longitudinal holes  328 , these seals and the transverse seals  408  are aligned at their ends by means of plug seals  210 , which have seal boxes  212  that tightly align with the seals and thus achieving a perfect seal with minimum friction. 
     FIG. 7 shows a cross-sectional rotor  128  and its circular seal  208  located between rotor  128  and stator  130 . This seal is provided with longitudinal slots  702  disposed along the external duct  304 , and allowing for the oil  302  to be evacuated through the expulsion cavity  704  by means of the oil pump  316  and centrifugal force. 
     FIG. 8 shows a fin  200  magnetized with positive and negative charges and a stator  130  having a series of independent electromagnets  802  magnetically energized, either positively or negatively for the purposes of repelling or attracting in relation to the necessary position of the fin  200 . Additionally, negative or positive charges may be concurrently activated to quickly brake the rotor  128 , all this based on the magnetic principle that same charges are repelled and contrary charges attracted. 
     FIG. 9 shows a compressor and/or vacuum pump type rotary internal combustion engine  900  where piston blades  200  perform two expansion cycles  902  and two contraction cycles  904 . Such piston blades  200  are transported due to torsion resulting from a power plant taking the power from the central shaft  906 , pushing the crankshafts  118 , putting into motion the connecting rods  116  due to pinion  120  motion of the crankshaft  118  which are moved through bearings  124 , which when displaced due to torsion actuates the central shaft  906  rotating the pinions  120  when supported by the fixed pinions  122  rotating twice per turn. In the entrances of expansion  902  and contraction  904  are located valves, such as check valves that allow for ingress and egress of air.
