Abstract
The present invention uses the exhaust gas of an internal combustion reciprocating engine to drive a turbine. The turbine is position around the cylinder. The turbine is connected to systems that will use the energy to improve the total system efficiency. One such system would be connected to a compressor to create the force induction required for two-stroke engines.
Claims8
A turbo-piston engine, including:
- an engine housing having a cylinder within said engine housing having an intake in a first end of said cylinder, at least one exhaust port in a second end of said cylinder, said engine housing further having an intake manifold and at least one intake channel therein communicating with said intake;
- an intake valve operably connected to said first end of said cylinder to open during intake of to receive air from said at least one intake channel and fuel and close post intake;
- a piston operably reciprocally disposed in said cylinder having a piston head and piston shaft, said piston head moving between a compression and an ignition positions to prevent air and fuel from exiting through said at least one exhaust port wherein air and fuel are trapped within said cylinder and an exhaust position to permit spent emissions to exit said at least one exhaust port;
- a drive shaft operably connected to said piston shaft;
- a turbine wheel operably concentrically rotatably disposed around said cylinder to receive exhaust from said at least one exhaust port;
- and
- a compressor wheel connected to said turbine wheel and rotatably disposed around said cylinder and in at least part of said at least one intake channel to be rotated by rotation of said turbine wheel and causing intake of air through said at least one intake channel within said intake manifold of said engine housing, said intake of air being compressed through said at least one intake channel within said intake manifold of said engine housing into said intake.
