Abstract
A rotary internal combustion engine includes an arcuate compression chamber, an arcuate expansion chamber, an output shaft, and a piston coupled to the output shaft for movement through the arcuate compression chamber and the arcuate expansion chamber. The piston has a leading end, a trailing end, an inlet valve that is located at the leading end of the piston for receiving a compressible fluid from the compression chamber and an outlet valve that is located at the trailing end of the piston for expelling a combustion gas into the arcuate expansion chamber.
Claims13
A rotary internal combustion engine, comprising:
- an arcuate compression chamber;
- an arcuate expansion chamber, wherein the arcuate compression chamber and the arcuate expansion chamber cooperate to define a substantially toroidal cylinder shape;
- an output shaft;
- a piston coupled to the output shaft, the piston having a leading end, a trailing end, an inlet valve located at the leading end, an outlet valve located at the trailing end, an internal combustion chamber in communication with the inlet valve and the outlet valve, an outer wall shaped complementarily to the substantially toroidal cylinder shape of the arcuate compression chamber and the arcuate expansion chamber, and an inner wall adjacent to the internal combustion chamber;
- and
- a heat exchange chamber that is formed in the piston between the outer wall of the piston and the inner wall of the piston and receives a cooling substance for cooling the piston.
A rotary internal combustion engine, comprising:
- an arcuate compression chamber;
- an arcuate expansion chamber;
- an output shaft;
- a piston coupled to the output shaft, the piston having a leading end, a trailing end, an inlet valve located at the leading end, an outlet valve located at the trailing end, and an internal chamber in communication with the inlet valve and the outlet valve;
- and
- a heat exchange chamber that is formed in the piston and receives a cooling substance for cooling the piston, wherein the cooling substance is expelled from the heat exchange chamber into the internal chamber.
A rotary internal combustion engine, comprising:
- an arcuate compression chamber;
- an arcuate expansion chamber;
- an output shaft;
- and
- a piston coupled to the output shaft, the piston having a leading end, a trailing end, an inlet valve located at the leading end, an outlet valve located at the trailing end, and an internal chamber in communication with the inlet valve and the outlet valve, wherein the inlet valve of the piston and the outlet valve of the piston are each controlled such that the inlet valve is closed and the outlet valve is open during combustion of a combustible mixture to propel the piston within the arcuate expansion chamber and such that the inlet valve and the outlet valve are open simultaneously subsequent to combustion of the combustible mixture to facilitate removal of byproducts of combustion of the combustible mixture from the internal chamber of the piston.
