Described sealing configuration is piston ring, the bottom of this piston ring embedded outer side surface at Hollow Pillar.

Described stroke limit structure comprises step surface and the top arc brake hoop at Hollow Pillar middle part, the top of described steam piston is that annular contraction mouth is stuck between the step surface and arc brake hoop at Hollow Pillar middle part, and described arc brake hoop bottom is provided with the location snap ring of arc convex.

Described exhaust valve is arranged on the top of cylinder cap, and it highly is higher than the upper end of steam piston.

The lower end surface of described Hollow Pillar is the end face that caves in, and the upper end of Hollow Pillar is connected with the cylinder cap upper-end surface by fastening piece, and the cylinder cap upper-end surface is provided with through hole and Hollow Pillar internal communication.

The described steam piston first half and Lower Half adopt respectively two kinds of materials, and the first half adopts high-abrasive material to make, and Lower Half employing good heat-transfer, metal or composite material that thermal expansion coefficient is little are made.

The first half of described steam piston is the elasticity structure of grid, and elasticity grizzly bar direction is consistent with the generatrix direction of steam piston outer surface.

The lower end surface of U-shaped Hollow Pillar is the structure of caving in, and the space that can guarantee vaporium can not disappear when the top dead center because of steam piston.

Beneficial effect of the present invention

The present invention is installed the steam cylinder additional by covering in internal combustion (IC) engine cylinder, can utilize the heat in the cylinder of internal-combustion engine to be converted into the power of steam piston, thereby realize providing larger power to internal combustion engine, and then improve power and the fuel utilization ratio of internal-combustion engine.

Mode of execution

Embodiment one: referring to Fig. 1-Fig. 6, a kind of internal combustion, steam combination engine, comprise ECM (engine control module), water cooling system, internal combustion engine cylinders, piston, wrist pin, connecting rod, bent axle, cylinder cap, be arranged on oil nozzle, intake valve and exhaust valve on the cylinder cap, the Hollow Pillar of U-shaped is installed in the described cylinder cap top, this Hollow Pillar is set with the steam piston of U-shaped outward, being provided with sealing configuration and stroke limit structure between Hollow Pillar and the steam piston, is air chamber between the lower end surface of Hollow Pillar and the steam piston lower end surface; The lower end surface of Hollow Pillar is provided with sprinkler and the exhaust steam valve that is communicated with air chamber.Described sealing configuration is piston ring, the bottom of this piston ring embedded outer side surface at Hollow Pillar.Described stroke limit structure comprises step surface and the top arc brake hoop at Hollow Pillar middle part, the top of described steam piston is that annular contraction mouth is stuck between the step surface and arc brake hoop at Hollow Pillar middle part, and described arc brake hoop bottom is provided with the location snap ring of arc convex.Described exhaust valve is arranged on the top of cylinder cap, and it highly is higher than the upper end of steam piston.The lower end surface of described Hollow Pillar is the end face that caves in, and the upper end of Hollow Pillar is connected with the cylinder cap upper-end surface by fastening piece, and the cylinder cap upper-end surface is provided with through hole and Hollow Pillar internal communication.The first half of described steam piston is the elasticity structure of grid, and elasticity grizzly bar direction is consistent with the generatrix direction of steam piston outer surface.
