A linear piston engine includes a housing having a combustion chamber located between opposing first and second piston chambers. A first piston assembly is located within the first piston chamber, and a second piston assembly is located within the second piston chamber. Each piston assembly includes a piston for reciprocating within the piston chamber. The piston is located adjacent to the combustion chamber. Each piston assembly also includes a crankshaft coupled to the piston for guiding the piston through a power stroke and a return stroke, and a linear output member coupled to the piston for providing a linear output motion based on reciprocating motion of the piston.

A hydraulic motor assembly includes a flow controller, a displacement controller and a hydraulic motor. The flow controller controls the flow of hydraulic fluid through the hydraulic motor and the displacement controller controls motor displacement. The hydraulic motor converts the pressure and flow into angular displacement of a drive shaft. An electrical generator is connected to the motor drive shaft and provides electrical power to accommodate a varying electrical load. As the electrical load varies, the flow controller and displacement controller vary the flow and displacement of the hydraulic motor to vary the torque applied to the generator by the drive shaft so that the drive shaft rotates at a desired speed.

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.
