Abstract: A genset has an enclosure in which a bulkhead separates the enclosure into a high pressure compartment and a low pressure compartment. A first fan is located in the high pressure compartment and draws ambient air into the high pressure compartment and pressurizes the high pressure compartment to a first pressure that is greater than ambient pressure. A radiator is located within the high pressure compartment such that the pressurized air in the high pressure compartment flows through the radiator and out of the high pressure compartment. A generator is located in the high pressure compartment and provides a gas flow path therethrough from the high pressure compartment to the low pressure compartment. An engine is located in the low pressure compartment and is coupled to the radiator for cooling and is coupled to the generator through the bulkhead to drive the generator.

Abstract: 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.
