A closed cycle engine power structure and a power generation method, includes a cylinder block and an inner shell. The inner shell is located at the cylinder block, and the inner enclosed cavity of the cylinder block is divided into an outer duct and an inner duct, and an electric coil is arranged in the inner shell. An Archimedes pump is arranged in the inner duct, the electric coil is in drive connection with the Archimedes pump to form a motor structure. Tension structures are arranged in the outer duct. The Archimedes pump is driven to rotate to form a pressure difference between the top and bottom of the cylinder block, generating airflow around the tension structures. According to Bernoulli principle, the pulling force is generated by tension structures. The tension structures concentrate on the cylinder block to form the power of the engine power structure.

An internal combustion engine for use in land, aerial and water vehicles and various kinds of machinery. A first version of the engine has a cylinder with the inlet channel of compressed air and the outlet exhaust channel situated in the middle of it. In the cylinder head as well as in the partition there are the fuel injector, the water injector and the ignition element. In the middle of the partition the slide bearing is embedded, through which the tappet rod goes. The upper end of this rod is attached to the bilateral piston, whereas its lower end is connected to the connecting rod. The water injectors are powered from the water container through the heating element and the metering device. A second version the engine has a plurality of cylinders in a radial orientation.
