Rotary internal combustion engine

摘要

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.

1. 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 for movement through the arcuate compression chamber and the arcuate expansion chamber, the piston having 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 arcuate compression chamber, an outlet valve that is located at the trailing end of the piston for expelling a combustion gas into the arcuate expansion chamber, and a fuel delivery port that provides a fuel directly to an internal chamber of the piston, wherein the compressible fluid is an oxidant that does not include fuel, the compressible fluid is mixed with the fuel in the internal chamber of the piston to define a combustible mixture, the combustible mixture is located within the internal chamber of the piston as the piston enters the arcuate expansion chamber, and the combustible mixture is combusted within the piston as the piston moves through the arcuate expansion chamber to produce the combustion gas.
