The sealing structure is a piston ring that is embedded in a lower portion of the outer side of the hollow post. The stroke limiting structure comprises a stepped surface in the middle of the hollow pillar and an uppermost curved brake ring, wherein the upper part of the steam piston is an annular shrinking groove stuck between the stepped surface in the middle of the hollow pillar and the curved brake ring The lower part of the curved brake ring is provided with a curved convex positioning snap ring. The air outlet is disposed at an upper portion of the cylinder head and has a height higher than an upper end of the steam piston. The lower end surface of the hollow pillar is an indented end surface, and the upper end of the hollow pillar is connected with the upper end surface of the cylinder head through a fastener, and the upper end surface of the cylinder head is provided with a through hole communicating with the interior of the hollow pillar. The upper part of the steam piston is an elastic grid structure, and the direction of the elastic grid is the same as the direction of the busbar of the outer surface of the steam piston.

The upper and lower halves of the steam piston described in this embodiment can be made of two materials, the upper part is made of wear-resistant material, and the lower part is made of metal or composite material with good heat transfer performance and small thermal expansion coefficient.

Taking a four-stroke engine as an example, the working process of the internal combustion and steam combination engine - The engine is in the four strokes of suction, compression, work, and exhaust, and the movement of the piston of the internal combustion engine is consistent with the operation of the conventional internal combustion engine. The steam piston only operates during the power stroke, and the spray head is connected to the internal combustion engine. In the cooling water system, the water supply is supplied to the spray head by the pump timing, and the time control is matched with the engine time control. After the ignition of the power stroke, the piston of the internal combustion engine is pushed down to perform work, and on the other hand, the water in the cooling water system is heated by the water pump. Water is injected into the steam chamber. The high temperature generated by the internal combustion of the internal combustion engine cylinder vaporizes the water in the steam chamber instantaneously. The steam chamber vapor volume expands and the steam piston also descends at the same time, so that the pressure of the steam is transmitted through the gas in the cylinder of the internal combustion engine. The internal combustion engine piston can improve the downward force and speed of the piston of the internal combustion engine, thereby improving the power of the piston of the internal combustion engine. Before the end of the internal combustion engine stroke, the exhaust valve is slammed, and the high pressure gas in the cylinder of the internal combustion engine pushes the steam piston back into place. .
