ABSTRACT:
This rotary internal combustion engine has two rotatable vane type pistons mounted for axial rotation in a sealed casing. In an exemplary cycle, one piston is released to rotate at or prior to initiating combustion in the combustion space between the two pistons, while the other remains fixed. As the free piston rotates around to the position where the fixed piston is located, it drives exhaust from a prior cycle out of an exhaust outlet and then compresses air towards the combustion space. The roles of the pistons are reversed on the next cycle. Two units may be operated in tandem so that the power stroke of one unit provides power to help finalize the cycle of the other. Hydrogen is used as a preferred fuel, and water preferably serves as a lubricant.
