Abstract: A novel combustion engine is disclosed that is also called the Mirabile engine (10). The Mirabile engine (10) comprises an air intake (18), an air compressor (22), coupled to the air intake (18), and a combustion chamber (24), coupled to the air compressor (22). A shuttle valve (50) is included and is placed between the air compressor (22) and the combustion chamber (24) to seal off the combustion chamber from the air compressor during combustion. The engine (10) includes a fuel supplier (70), coupled to the air compressor (22) and the combustion chamber (24), to deliver fuel to the air after intake to provide a fuel/air mixture that has been compressed within the combustion chamber (24). The invention further comprises a crank shaft (46), rotatably coupled to the air compressor (22) to operate the air compressor and to transfer power generated by the engine (10) to a useful purpose. A turbine piston (12) is also included, which is coaxially coupled to the crank shaft, and travels in a circular path.

Abstract: A novel combustion engine with turbine like properties is disclosed. The novel engine (10) comprises an air intake, a first compressor stage, coupled to the air intake, a second compressor stage, coupled to the first compressor stage, a transfer valve, placed between the compressor stages and an annular race. Within the annular race, toroidal piston travels and passes over the transfer valve. The valve, toroidal piston and race form a temporary combustion chamber that expands as the piston travels within the annular race. Compressed air and fuel are introduced into the temporary combustion chamber and ignited to release the chemical energy and force the turbine piston to travel faster within the annular race. The first compressor stage is rotatably coupled to a crank shaft, which drives the first compressor stage and connects to an armature, which also connects the turbine piston so that useful work can be extracted from the energy released from the combustion of the fuel-air mixture.
