Rotary engine with rotary power heads

A rotary engine comprising:

• a casing having a first circular boring of a first size and a second circular boring of a second size that is smaller than the first size, wherein the first circular boring is interconnected with the second circular boring;
• a piston rotor having one or more pistons positioned in the first circular boring and movable in a rotating manner within the first circular boring in the casing, the piston rotor having at least three depressions formed in a circumference of the piston rotor, the at least three depressions defining, within the first circular boring:
• one or more intake/compression chambers,
• one or more power/exhaust chambers, wherein each of the one or more power/exhaust chambers is adjacent to a respective intake/compression chamber, and
• one or more cooling chambers, wherein each of the one or more cooling chambers is between a respective intake/compression chamber and a respective power/exhaust chamber;
• a power head positioned within the second circular boring and configured to rotate within the second circular boring, the power head including an exhaust port to vent exhaust gases into a ported hollow center shaft within the power head;
• a rotor shaft extending centrally from the piston rotor;
• a carburetor having a fuel intake port and an air intake port in gaseous communication with the collector ring to supply the fuel/air mixture into the collector ring;
• and
• a capacitor discharge solid state ignition system on the casing, the capacitor discharge solid state ignition system having a spark plug module that is located under the power head, wherein the spark plug module is configured to ignite a fuel/air mixture in the one or more intake/compression chambers at or near top dead center.
