Abstract

Methods, devices, and systems for power generation through liquid piston internal combustion engine. The liquid piston internal combustion engine of the invention utilizes a novel, synergetic combination of internal combustion and steam piston engines within the framework of one and the same system. The engine may comprise a plurality of cylinders, each having a liquid piston.

Claims (23)

1. A liquid piston internal combustion engine comprising:

a) a power generating module having at least one cylinder and at least one piston comprising at least in part the surface of a first working liquid, thus forming a liquid piston, the power generating module also comprising a booster that converts energy of said first working liquid into energy of a second working liquid and;

b) an output means to convert thermal energy generated in a process of combustion in said cylinder into non-thermal energy.

2. The liquid piston internal combustion engine of claim 1 wherein said booster is integrated with said cylinder.

3. The liquid piston internal combustion engine of claim 1 wherein the first working liquid is water.

4. The liquid piston internal combustion engine of claim 1 wherein the first working liquid is aqua-based electrorheological liquid.

5. The liquid piston internal combustion engine of claim 1 wherein the first working liquid is aqua-based electro-conductive liquid.

6. The liquid piston internal combustion engine of claim 1 wherein said second working liquid is water.

7. The liquid piston internal combustion engine of claim 1 wherein said second working liquid is electro-conductive liquid.

8. The liquid piston internal combustion engine of claim 1 wherein said second working liquid is hydraulic oil.

9. A liquid piston internal combustion engine comprising:

a) a power generating module having at least one cylinder and at least one piston comprising at least in part of the surface of a first working liquid, thus forming a liquid piston, the power generating module also including therein a cylindrical valve body having a plurality of valve openings; and

b) an output means to convert a thermal energy generated in a process of combustion in said cylinder into non-thermal energy;

wherein the cylindrical valve body includes at least one low pressure fuel cavity.

10. The liquid piston internal combustion engine of claim 9 wherein the first working liquid is an aqua-based electrorheological liquid and said system of valves is formed in situ by said aqua-based electrorheological liquid and includes: a) a grounded hollow body; and b) an insulated wire running through said grounded hollow body.

11. A liquid piston internal combustion engine of claim 9 , wherein the power generation module further includes a directional valve located therein.

12. A combustion engine comprising:

a) combustion chamber;

b) an output means coupled to the combustion chamber that converts a thermal energy generated in said combustion chamber during a combustion process into non-thermal energy; and

c) wherein further said combustion process is isochoric and kinematically and dynamically decoupled from said output means.

13. The combustion engine of claim 12 wherein said output means includes the energy-bearing flow of first working liquid.

14. The combustion engine of claim 12 wherein said output means comprise a moving output shaft.

15. The combustion engine of claim 12 wherein said combustion within said combustion chamber is initiated by a spark plug.
