    摘要： Unique engines, air compressors, and pneumatically driven electrical generators are disclosed. The engine employs a rotor having a number of pistons slidably disposed within respective cylinder bores extending into the rotor periphery. As the rotor spins within a stator, each cylinder bore passes a combustion stage at which the piston is driven further into the rotor toward a bottom of the respective cylinder bore. Valves at the bottom of the cylinder discharge air that is compressed by this piston downstroke, and admit new intake air during an opposing upstroke. The unit thus operates as a self driven compressor, or engine-compressor combination, and the compressed air may be used to pneumatically drive a turbine of an electrical generator. A carbon splitter dissociates carbon and oxygen molecules from the carbon dioxide in the air downstream of the generator turbine, reducing the overall carbon dioxide output of the system.

    摘要： The present invention provides a cooling structure of a cylinder block, the cooling structure being capable of improving a cooling performance of sliding surfaces. A cylinder block includes a plurality of cylinders, and pistons are respectively inserted into the cylinders through openings. Each of the pistons performs reciprocating sliding on a sliding surface which defines the cylinder. A plurality of cooling depressions are formed on an outer peripheral surface of the cylinder block. Each of the cooling depressions extends from a front end surface of the cylinder block on a dividing wall located between the two adjacent cylinders and is formed by reducing the thickness of the dividing wall so as to reduce a thickness of a portion between the sliding surface and the outer peripheral surface.
